Description

The application process of light indication in product and circuit
Method of the present invention, be utilize found, be total design with the indication of light, supervision and monitoring to duties such as voltage, electric current, fuses in circuit and product.
1. the shortcoming of existing use interchange or D.C. voltmeter and reometer is as follows:
A. the cost height of instrument; Except that the large-scale power switch board or the electric equipment of having relatively high expectations, as refrigerator and lathe etc., generally do not establish two kinds of instrument, so inconvenience or can not monitor and monitor the duty of electric component or electromechanical equipment at any time, can not in time find the obstacle place, damage electrical equipment and electromechanical equipment easily, the time that maintenance and equipment stopping production are stopped using is all long.
B. the indication of instrument is not obvious; During far away or ambient black, just be difficult for maybe can not having seen the indication of instrument apart from instrument as the people.
C. instrument is shock-sensitive moving; Because of the precise structure of the instrument shake machine of ability machinery not, so can not be in the basis of electronic shake stamper, electric hand drill, motor etc. on one's body by the dress instrument.
D. can not be on compact electric apparatus, by the dress instrument; Because of the volume of instrument is big, so can not press dress voltage table and reometer on one's body in the basis of on-load switch classes such as supply socket, electric hand drill, electric cooker, glue lid lock and contactor.
E. voltage table and reometer are subjected to the interference in various magnetic fields easily; Because of the coil of the suitable closed-loop path of moving-coil of instrument, the fixed coil of moving-iron voltmeter, permanent magnets etc. are subjected to the induction in various AC and DCs magnetic fields such as low frequency and high frequency easily and influence, and indication is inaccurate.
Big because of the volume of instrument again, use every methods such as magnetic metals, when isolating instrument, also pretty troublesome.
The supply voltage situation that F. can not reflect terminal appliance; On the electric control cabinet as high capacity motor, though be provided with voltage table and power light, but just city's power supply voltage of indication, rather than city's power supply also will pass through circuit, various switches (the starting conversion of star angle and fall along etc. switch), the supply voltage situation of the various electrical equipment such as motor of back terminal such as fuse, so the voltage table on the switch board and the indication of pilot lamp sometimes, to make situation And inconsistent with the practical power of electrical equipment such as motor and worker.
Therefore, damage electrical equipment or plant equipment easily, the time that maintenance and equipment stop production is all long.
H. low because of the internal resistance of instrument, so when the measurement internal resistance height power supply that power is little again, error is big, not even energy measurement and the actual conditions that demonstrate power supply.
2. prior art is to the supervision and the monitoring aspect of fuse (comprising melt and fusible core), and the shortcoming of existence is as follows;
A. at aspects such as electric control cabinets, also not having can be from switch board in appearance, can directly monitor the product with a plurality of fuse working conditions of Monitoring and Controlling cabinet inside.
B. do not establish the disconnected not fuse of telltale of indication melt; As fuses such as various fuses and RM, because of can not monitoring at any time and find that melt is disconnected, easily phase shortage such as threephase motor is damaged, and the time that maintenance and equipment stop production is also all long.
C. be provided with the fuse of mechanical signal method; Assembly technologies such as the small-signal thing of mechanical signal method, thin metallic signal lines, Xiao Dan Huang bother, labour productivity is low, cost is high.
As fuses such as RTO because of structure is limit, the mechanical signal thing must be located at fuse side, is human eye inconvenient or can not see directly that the signal thing comes off? especially set up space in switch board little, dark, when again a lot of groups of fuses being set, just more inconvenient and can not monitor and find that the melt of which fuse has broken?
Though human eye can directly be seen the mechanical signal thing on the screw base fuse fronts such as RLJ, but because of the signal thing little, so darkly again in the cover of fuse still be difficult for seeing clearly the signal thing and whether come off? don't you in addition, all see having electric current to pass through in appearance at various fuses?
Because of the shortcoming of basic structure, melt is had no progeny sometimes, and signal Wu And does not come off! And cause melt disconnected mistake indication and false picture, make phase shortage such as threephase motor and damage the time that ， And has prolonged maintenance and equipment stopping production.
Extraordinary big electric current of moment when starting motor or cold conditions heating wire etc., though melt can bear moment extraordinary big electric current and constantly, but mechanical signal lametta with Rong Ti And connection, but fused by the shunting of melt, after signal is come off, demonstrate melt disconnected mistake indication and false picture, give the operator and overhauled people Dai Lai many troubles.
By the poor reliability of the above-mentioned mechanical signal method of what, when making product or sample do type approval test in quality monitoring department, it is qualified to be difficult for, and is difficult to obtain conformity certification.
The Multifunctional fuse of embodiment 1. monomers
Present embodiment is a new purposes of utilizing prior art melt and Zhi Shi Deng And linked method, and used various high pressure of electric equipment and low-tension fuse are improved, and closes the shortcoming that what is wanted improved fuse, explanation in A～C joint of aforementioned 2..
Purpose of the present invention:
1. on the high pressure and low-tension fuse of not establishing the disconnected not telltale of any indication melt, set up the disconnected device not of light finger-length measurement indication melt, the existing fuse that breaks and deny with mechanical signal method indication melt, cancellation mechanical signal method part, change the disconnected device And not of light finger-length measurement indication melt into the light indication is located at the front of fusible core or fuse base, so that what surveillance and monitoring at any time.
2. on the seat of fuse or on the circuit, set up light indication with reometer effect, does can find out in fuse (or melt or fusible core) have electric current to pass through?
3. the fuse (or melt or fusible core) after improving, melt is had no progeny, and pilot lamp is bright, and when melt was not disconnected, pilot lamp did not work, and after the light stream lamp is connected, forms new good effect.
4. the light indication that can utilize melt to have no progeny as the indicator of the maintenance short circuit or the obstacle that opens circuit, can be shortened the time that maintenance and equipment stop production.
5. the fuse after improving all still can keep existing GB and the whole technical conditions ， And of international target to increase the multi-functional of light indicator signal method.
6. can be in face of switch board, whether each fuse that can understand switch board inside disconnected with the light indication of watching on the switch board? is there electric current to pass through? the damage that can avoid the three phase electric machine phase shortage to cause can also be shortened the time that maintenance and equipment stop production.
One of technical measures of the present invention, shown in Figure 3 as in the accompanying drawing 1, the meaning of figure Chinese words is as follows:
A, B-exchange or direct supply, low pressure such as 90V～600V, or the high pressure of 10KV etc.RD-fuse (comprising seat or cover) or melt or fusible core.
XD1-monitors and monitors the pilot lamp of RD, also is called for short the molten lamp of light, and working current is few.
XD2-plays the pilot lamp of reometer effect, also is called for short the light stream lamp, and operating voltage is very little.
The divert shunt resistor of R1-light stream lamp.The load of R2-power supply is as the elementary winding of electric light, heating wire, motor winding, AC transformer, televisor, refrigerator etc.
Concrete structure is: can put the molten lamp of light in the what fusible core or the outside of fusible core itself etc., or molten lamp of light and light stream lamp etc. are put on the seat of what fuse, so that find and the indication of supervision light.
Principle of work is as follows:
When A and B end has the power supply input, as power supply load R2 nonoverload again during not short circuit, RD is continuous, because of XD1 is not worked by the RD short circuit, indication melt working properly, the electric current of power supply during by light stream lamp XD2 bright, the brightness of light stream lamp determine that by the many or few of working current of power supply load R2 the task of shunt resistance R1 is, divide its aftercurrent remove many whats of melt rated current light stream lamp working current, the light stream lamp can because of voltage or electric current is not excessive not be damaged.
During as power supply load R2 overload or short circuit, melt is had no progeny, if power supply A is through the molten lamp of light, light stream lamp, shunt resistance, behind the R2, B becomes the loop with power supply, the working current that melts lamp because of light is few, be that internal resistance is very big, so in the landing of the voltage at A and D two ends, the supply voltage of only lower slightly what A and B end and bright, send the disconnected light indication of melt, simultaneously, few because of the electric current that the molten lamp of light flows through XD2, R1, R2, R2 quits work so power supply is loaded, the light stream lamp has not worked yet, and only plays the effect of conduction in the loop of electricity.
The application of this light indicating fuse when the protection of power supply load short circuit and maintenance;
The obstacle that is short-circuited such as circuit is more common peril! Immediate current is extremely many during because of short circuit, and electric arc is very big, and temperature is very high, causes accidents such as fire and electric shock easily.
When using this light indicating fuse as protection, when short circuit obstacle such as circuit takes place, melt has no progeny, the light indication is bright.Little as brightness, illustrate that short circuit place has not directly contacted, it is bigger that the little reason of brightness belongs to relevant insulating resistance value, but still meet electricity and the safe operation condition sent, the sensitivity of Yin Ben light indication is very high, therefore send electricity behind the melt that can change or the fusible core, and equipment can recover operate as normal.
Have no progeny as melt, when the brightness of light indication is big, illustrate that short circuit place melted together because of electric arc, or the little what of relevant insulating resistance value of short circuit place duty normally, answer the brightness variation that frontier inspection is repaiied, the limit monitors the light indication? after finding short circuit place or handling the insulation obstacle well, the brightness of light indication becomes very little or when not working substantially, illustrates that obstacle got rid of, behind the melt of changing again or fusible core, operate as normal can have been recovered.
Utilize the light indication of this light indicating fuse, the method for overhauling the obstacle that opens circuit;
With the have no progeny light indication of light indicating fuse of (when needing, but the people is for doing disconnected melt) of melt, can be used as the indicator of the obstacle that opens circuit such as maintenance circuit.
When maintenance has the internal wire of insulating protective layer, disconnected as electric wire, because of not becoming the loop,, but when crooked a certain section electric wire, indicate as discovery light and to neglect brightly when not working suddenly so the light indication does not work with power supply, illustrate that the metal wire of this section electric wire insulation layer inside is disconnected.
Good effect of the present invention is as follows:
1. reasonable because of the basic structure design of light indicator signal method, so the performance of indication has reliably been howed than the mechanical signal method, when product or sample are done type approval test in quality monitoring department, obtain conformity certification easily.
2. when light indicator signal method being improved existing various fuse with what, carrying on as before has kept all technical conditions such as existing GB and international target size and pitch-row etc., thus users at home and abroad new with or very convenient when replacing existing old product.
3. because of being located at the light indication front center in the face of the fuse of human eye, so be exactly apart from several meters distant places, also can see clearly be located at the switch board inner space little, dark, be provided with the light indication which melt in many group fuses are had no progeny, therefore, can reduce or avoid the damage ， And of threephase motor etc. can shorten to overhaul and time of equipment stopping production.
4. utilize the light indication of fuse, as the maintenance short circuit or when opening circuit obstacle, be not only safety but also practical, also be existing machinery signalling fuse basic do less than function.
5. the corresponding Deng And connection on the molten lamp of the light on the switch board and light stream lamp and the fuse, can be in face of switch board, the working condition of each melt of many groups fuse of supervision and Monitoring and Controlling cabinet inside, time of maintenance and equipment stopping production is shortened in the damage that can reduce or avoid phase shortage such as threephase motor to cause.
6. the good assembling process of light indicator signal method is done, so cost is also low.
The multi-functional fustat that embodiment 2. single phase poaer supplies are used
Existing RL1 screw base fuse; RTO enclosed tubular cut-out, RN type high-tension fuse etc.; seat or cover and fusible core (being melt) by fuse are formed; the parts product that has only the overload or short-circuit protection simple function; set up in electric control cabinet etc.; and the overwhelming majority is provided with many group fuses, and existing shortcoming is as follows:
1. on one's body the basis of fuse, do not have, can not can not also set up voltage table and reometer, so just directly the power supply input be arranged with timely understanding fuse? is there there power supply output? is there electric current to pass through the (working current that power supply load R is promptly arranged in melt or the fusible core?)? whether melt disconnected? which melt broken (because of general single-phase equipment uses two fuses)?
2. when circuit or fuse obstacle, or after having a power failure, lamp lighting does not work, and is found by the people easily, but the discovering device inside heating wire heat supply etc. of out-of-work constant temperature oven etc. in time! And it is also long to influence stop production time of stopping using of work, output, quality ， And and maintenance and equipment.
3. there are being power supply input and fuse disconnected again with ing, and when power supply output is arranged, because of not having the reometer supervision and monitoring.So in the pulpit in cinema or auditorium etc., when a plurality of electric lights such as remote control ceiling or other electrical equipment, the electric light failed can not which in time to be found, or other electrical equipment has stopped work! And influence work or effect.
4. at electric control cabinet etc. in appearance, does can not be directly acquainted with inner set each the group fuse of switch board have the power supply input? is there there power supply output? whether melt disconnected? has which melt broken? is there electric current to pass through in which melt?
5. in the inside, back of maintenance switch board when respectively organizing fuse, little, dark because of the inner space, in the time of must directly contacting electrical equipment with instrument again, aptitude test goes out the result, so the time of maintenance and equipment stopping production is long, accidents such as maloperation and error shock takes place easily again.
6. because of in electric loop, not having current-limiting apparatus, so when starting motor, bulb, heating wire etc., moment, extraordinary electric current was very big, the energy of electricity wasting not only, but also damage melt, switch contact, various electrical equipment etc. easily.
Purpose of the present invention is as follows:
1. on one's body the basis of fuse, attach the light indication of voltage table and reometer effect, can be at any time apart from 5～10 meters distant places of fuse, does can see the fuse end have the non-transformer input? does the fuse end have non-transformer output? whether melt disconnected or logical? is there no current to pass through in the melt?
2. in the back of electric control cabinet, when overhauling the fuse of switch board inside, though the space is little dark again, do not need directly to contact and the test fuse with instrument yet, as long as several meters distant places with eye distance fuse group, can find out power supply input, the power supply output of each fuse, whether melt is disconnected, in the melt situations such as no current passes through arranged.
3. the about 5 meters distant places before the electric control cabinet outward appearance just can find out whether power supply input, power supply output, the melt of each fuse of switch board inside be disconnected, in the melt situations such as no current passes through have been arranged.
4. after forming with the seat of fuses such as existing RTO and fusible core etc., can improve and develop the quality and the function of fuses such as RTO, and become a new kind, but also keep the GB of fuses such as RTO and whole basic fundamental conditions of world mark.
Technical measures of the present invention two, shown in Figure 7 as in the accompanying drawing 2, literal meaning is as follows;
A, B-establish 220V from the high pressure or the low-tension supply of power load switch.
XD1-is located at originally on one's body power supply input optical pressure lamp of fuse, 220V.
It is apparent that XD2-is located at switch board, the power supply input optical pressure lamp of fuse in the indication cabinet.
The fuse of RD1-power supply A, or melt or fusible core.
XD3-monitors and monitoring be located at fuse originally on one's body the light of RD1 melt lamp.
XD4-is located at that switch board is apparent, the molten lamp of light of RD1 in the monitor rack.

XD9-is located at originally on one's body alternator indicator of fuse, also claims the light stream lamp.
It is apparent that XD10-is located at switch board, the light stream lamp of the electric current of fuse in the indication cabinet.
The load of R-power supply is as bulb, heating wire, motor winding, televisor etc.
E, F-fuse be on one's body power output end originally.
Principle of work is as follows:
When A and B end has the power supply input, XD1 and XD2 be bright, during as power supply load R nonoverload or not short circuit, RD1 and RD2 constantly lead to, XD7 and XD8 are bright, point out that fuse has power supply and exported, power supply A is through arriving the E end behind the L1, the E at power supply load R two ends and F end obtain power supply and work, because of the working current of power supply load R during by L1, so L2 has power supply output light stream lamp XD9 and XD10 bright, brightness big or little is more than the working current of R or few decision, because of XD3 and XD4 are not worked by the RD1 short circuit, XD5 and XD6 are not worked by the RD2 short circuit.
If after power supply load R overload or the short circuit, RD1 is disconnected, behind power supply A process XD3, XD4, XD7, XD8, L1, R, the RD2, B becomes the loop with power supply, because of the working current of XD3 and XD4 is more littlely than XD7, XD8, L1, R etc., bright so the A of the landing of the voltage of the A at XD3 and XD4 two ends and C end, smaller what power supply and B hold, point out that melt RD1 is disconnected, power supply output optical pressure lamp XD7 and XD8 have not worked, and power supply load R has also just quit work.
Have no progeny as RD2, the indication of its relevant light, the principle and the logic of having no progeny with aforementioned RD1 are the same.
Good effect of the present invention is as follows:
If before the switch board appearance 5～10 meters distant places, can only export with power supply input, the power supply of each group fuse of watching out switch board inside, whether melt is disconnected, which melt broken, the indication by the light stream lamp, can also find out the working condition of power supply load R, can find in time that concrete obstacle place ， And can shorten the time of maintenance and equipment stopping production.
2. in the back of switch board, maintenance switch board inside respectively organize the work of fuse the time, though the space is little dark again, do not need to do engaged test with instrument yet, as long as apart from the about 5 meters distant places of fuse, can find out power supply input, the power supply output of each group fuse, whether melt is disconnected, and which melt And that broken indicates by the light of light stream lamp, can find out the working condition of power supply load R, And can avoid accidents such as maloperation and error shock, shortens the time that maintenance and equipment stop production.
3. as cinema or auditorium etc.; except that doing overload and the short-circuit protection with this fustat; also can be used as and monitor and monitor remote control ceiling lamp at a distance etc.; as after opening power supply; output optical pressure lamp is bright; but the light stream lamp does not work, illustrates power supply output, be that the bulb etc. of remote control is bad, so just there is not source current.
4. utilize the light indication that melt has no progeny, can be used as the maintenance short circuit, open circuit, the indicator of obstacle such as insulation.(concrete grammar is similar to embodiment 1 with principle)
5. because of fuse is the basic guard block that used high pressure in countries in the world and the various electric equipments of low pressure must be used, and has only the simple function of overload or short-circuit protection substantially.
Advanced major step by leaps and bounds by purpose of the present invention and good effect, the function that makes fuse and quality, the GB of fuses such as RTO and the basic fundamental condition of international mark have also been kept, so when doing type approval test, have technical conditions to comply with, but also increased multi-functional.
Because of the current transformer string in the loop of power supply and power supply load R, when starting motor or cold conditions bulb and heating wire etc., the induction reactance of current transformer, the extraordinary big electric current that starts moment there is metering function, can save the energy of electricity, also can reduce the damage of electrical equipment, and prolong the life-span of various electrical equipment.
The multi-functional fustat that embodiment 3. three-phase supply are used
During as overload or short-circuit protection, there is following shortcoming in various fuses such as used RTO of three-phase supply such as existing switch board and RM type;
1. before the appearance of switch board, can not inconvenience maybe be directly acquainted with the power supply input of each single-phase fuse of switch board inside? power supply output? whether melt disconnected? is there no current to pass through in the melt? as monitor at the device in appearance of switch board and during measuring instrument, cost height, the side of occupationing of land greatly, indicate also not obvious,, just be not easy to have seen clearly during slightly far away or ambient black apart from instrument.
2. when three-phase supply input phase shortage or the phase shortage that single-phase melt is had no progeny and caused, be difficult for all in time being found that damage the winding of threephase motor etc. easily, the time that maintenance and equipment stop production is also all long.
3. in the back of switch board, during each fuse of maintenance switch board inside,, also must directly contact electrical equipment and test with instrument because of the space is little dark again, thus accidents such as maloperation and error shock take place easily, and also the off-time of maintenance and equipment is also all long.
4. in the loop of power supply, lack current-limiting apparatus, thus when starting motor or cold conditions heating wire etc., moment extraordinary big electric current, wasted the electric energy, also damage melt or various electrical equipment easily.
Purpose of the present invention is as follows:
1. on one's body the basis of multi-functional fustat, if have the light indication of six voltage tables and three reometer effects, can be at any time apart from the about 5 meters distant places of fuse, find out that three single-phase power supplys inputs, power supplys output, the melts of each group are disconnected not, have in the melt no current to pass through etc.
2. about 5 meters distant places of face before or after the appearance of switch board, the light indication that whether three single-phase power supplys inputs of each group, power supplys output, the melts that can find out switch board inside at any time are disconnected, have in melt or the power supply no current to pass through etc., and than the instrument indication, many significantly.
3. the control of switch board great majority has the power supply of three-phase current motor, when using this fuse, the about 5 meters distant places of face before or after the outward appearance of switch board, can find power supply phase shortage or under-voltage at any time, fall along or the starting conversion of star angle wait not contacting of switch contacts, or loose contact, or three asynchronous concrete places of obstacle of waiting of single-phase contact action are located.
4. use this fuse, can reduce or avoid the damage of phase shortages such as threephase motor, shorten the time that maintenance and equipment stop production, reduce or avoid the accident of maloperation and error shock etc.

If after A phase power supply load R1 overload or the short circuit, RD1 is disconnected, A phase power supply is by molten lamp XD7 of light and XD8, L2, behind the R1, become the loop with C phase power supply mutually with B, the working current that melts lamp XD7 and XD8 because of light is few, the internal resistance of the molten lamp of light is more than L2 and R1 the earth in other words, so voltage landing at A and D end, the 380V of the line voltage of only lower slightly what A phase and bright, point out that RD1 is disconnected, but the landing of the voltage of the G of R1 and H end is very little, so power supply load R1 has stopped work, A phase power supply output optical pressure lamp XD13 and XD16, reaching XD15 and XD18 does not just work smaller with brightness, by the duties such as motor of power supply load, and melt is disconnected when starting motor, or melt is disconnected etc. behind the normal starting has determined, after A phase power supply load R1 quits work, can also find out by the obvious light indication of light stream lamp XD19 and XD20, because of the electric current of the elementary winding L 2 of current transformer LH1 of flowing through has not had (as the words of the molten few working current of lamp of photometric not), so light stream lamp XD19 and XD20 have not just worked significantly.
When the RD3 of the RD2 of B phase or C phase has no progeny, various principle of work about the light indication is identical with the logic that the RD1 of aforementioned A phase has no progeny.
If G, H, the output terminal of the three-phase supply of I, before supplying the threephase motor of terminal, in the time of also will passing through the switches such as suitable or star angle conversion of control motor earlier, when not contacting because of obstacle as a certain single-phase contact, relevant single-phase light stream lamp does not just work, during as loose contact, the light stream lamp is just neglected and is not brightly worked suddenly, move when asynchronous as relevant three single-phase contacts of hand motor starter (methods such as reduced voltage starting or the conversion of star angle), the light indication of three single-phase light stream lamps can be not synchronous yet, can and adjust according to the abnormal conditions maintenance, otherwise motor starting difficulty or fail to start.
As G, H, the three-phase power output end of I, when being the power supplys such as heating wire for production equipment inside such as constant temperature oven, because of not establishing six voltage tables and three reometers, so as three-phase supply input phase shortage, or a certain single-phase melt is disconnected, or the contact of a certain single-phase switch is can not contact because of obstacle the time, the part heating wire of device interior is quit work, easy being found unlike illuminating lamp directly perceived does not work just, when finding again behind the certain hour, caused damage for the matter or the amount of product, as the time with Multifunctional fuse of the present invention, by the unusual indication of light stream lamp, just which single-phase heating wire of discovering device inside has quit work at any time.
Good effect of the present invention is as follows:
1. on one's body the basis of this multi-functional fustat, if after having the light indication of six voltage tables and three reometer effects, can find out three single-phase power supply input and output at any time, whether phase shortage, melt be disconnected, the situations such as electric current of power supply, more obvious than the indication of instrument, cost is low, technology is simple, account for the various obstacles that fall switch contacts such as suitable or the conversion of star angle that occupy a narrow space, solve easily antimagnetic interference, can find out the control motor at any time.
2. in the front of switch board in appearance or the back, can both find out at any time 1. various multi-functional, and the metering function of current transformer outside economizing on electricity, also can reduce electrical equipment and damage.
3. can reduce or avoid the motor of directly perceived or remote control and heating wire etc., because of power supply phase shortage or melt have no progeny the phase shortage that causes damage or influence the work of equipment, can shorten and overhaul and time of equipment stopping production, reduce or avoid the accident of maloperation and error shock etc.
4. make various fuses such as existing RM and RTO increase new purposes and multi-functional, the quality And that has improved product becomes new kind, when product quality supervision department does type approval test, can be with reference to the GB of existing product and whole basic fundamental conditions of international mark, so test and evaluation are qualified easily.
The multifunctional power socket that embodiment 4. single phase poaer supplies are used
Various single phase poaer supply sockets are field electrical equipment plug components commonly used such as civilian and industry, and existing shortcoming is as follows:
1. lack, also can not on socket, set up voltage table and reometer, also do not establish pilot lamp; So when ambient black, be difficult for finding the socket site, when maintenance and power failure etc., does can not understand socket at any time have? is there there working current? can not find easily to forget to close or forget to pull out power supply by inner electrical equipment such as power supply, the particularly human eye gate light that can not directly find, remote control of the electric blanket of socket power supply, electrical heating shower etc. or refrigerators! Both waste the electric energy, shortened the life-span of electrical equipment again, also can breaking out of fire, accident such as maloperation, error shock.
2. be directly to supply with because of the power supply in the socket by city's power supply, lack current-limiting apparatus, in the moment of supplying with bulb, televisor, fan blower, various electric heaters etc., many whats of electric current running current of surging of starting is doubly a lot, not only the serviceable life of the energy of electricity wasting, shortening electrical equipment, also damage the inner fuse such as televisor and refrigerator and the contact of various switch etc. easily.
Four of technical measures, shown in Figure 4 as in the accompanying drawing 1, the meaning of figure Chinese words is as follows:
The output terminal of C, the multi-functional single-phase supply socket of D-.
The input in A, B-electric main source, 220V.The RD-midget fuse.
The optical pressure lamp of XD1-indication power supply input, 220V.
XD3-monitors and the light of monitoring fuse RD melts lamp.
The optical pressure lamp of XD2-indication power supply output, 220V.
The electric load of R1-power supply is as bulb, televisor, motor, heating equipment etc.
XD4-monitors and monitors the light stream lamp of the electric current of power supply and power supply load.
The divert shunt resistor of R2-light stream lamp XD4.
Principle of work is as follows:
When city's power supply is input to A and B end, power supply input optical pressure lamp is just bright, as power supply load R1 nonoverload again during not short circuit, when fuse RD constantly leads to, if the electric current of A end power supply, through RD, R1, XD4, behind the R2, become the loop with the B end of power supply, because of the resistance value behind light stream lamp and the Fen Liu Dian Zu And connection, little what power supply load R1 is a lot, so the voltage landing of B and D end is very little, about about 3V, makes the supply voltage of socket output, the voltage of city's power supply input of only lower slightly what A and B end, so can not influence the televisor of power supply load, washing machine, electric blanket, the operate as normal of desk lamp etc. and characteristic, XD4 is bright for the light stream lamp, has played the effect of reometer, brightness big or little is more than the electric current of power supply load or determined less.
The power supply output optical pressure lamp that is connected on B and C end is bright, and the existing power supply of indication socket has been exported, and the optical pressure lamp has played the effect of electric power output voltage table.
And what fuse RD two ends, monitor and the molten lamp XD3 of the disconnected light not of monitoring fuse, because of by the short circuit of fuse institute,, point out that also fuse is not disconnected so do not work.
But after the various electrical equipment overloads or short circuit of power supply load, fuse RD is disconnected, because of A and B end still has city's power supply, if the electric current of power supply melts lamp XD3 by the A end through light, XD2, R1, R2, behind the XD4, become the loop with the B end of power supply, the working current that melts lamp because of light is few, the internal resistance that is the molten lamp of light is big, so land very big at the A of the molten lamp of light and the voltage of C end, the power supply input of only lower slightly what A and B end is and bright, and indicating fuse RD is disconnected, and the C and the D end group of socket power output terminal originally do not have power supply to export simultaneously, so the washing machine of power supply load etc. has just quit work, power supply output optical pressure lamp XD2 has not just worked yet.
The task of the shunt resistance R2 at And what light stream lamp XD4 two ends is that branch removes the part electric current of nominal current (as series such as 5A) many whats light stream lamp working current of socket, also can protect the light stream lamp to avoid the excessive damage that causes of voltage and current.
Good effect of the present invention is as follows:
1. because of two optical pressure lamps of the power supply input and output on the socket, have the about 10 meters distant places of effect ， And energy distance of two voltage tables of power supply input and output, thus just can find the socket place, thus easy to use, and environment is dark more, and indication ground is obvious more.
2. as after maintenance or having a power failure, needn't open or close electric light etc. again, see if there is electricity or sent a telegram here? as long as with bright not the working of optical pressure lamp of the power supply input and output on the socket once soon? whether can understand has had electricity.
3. during as by the power supply of socket power supply refrigerator, but do not freeze? the available light of seeing on the socket of observing is indicated, as the power supply input and output, when the molten lamp of light stream lamp, light does not all work, illustrating does not have power supply input, and reason may be that the melt of total lock break, or overhaul that the power supply failed etc.
As see that power supply input optical pressure lamp is bright, but power supply output optical pressure lamp does not work, the molten lamp of light is bright, illustrate that socket has the power supply input, but do not have power supply output, reason is that the fuse on the socket has broken, should overhaul earlier whether washing machine etc. transships or obstacle such as short circuit after, the fusible core of changing again, equipment has got final product operate as normal.
Be when supplying the electric light of remote control auditorium ceiling, that inconvenience can not monitor maybe whether each electric light bright in the pulpit by socket? as long as see the light indication of the light stream lamp on the socket, as bright, illustrated that electric current passes through, electric light is bright, as does not work, and is that the lamp etc. of remote control is bad.
4. because of the light stream lamp with after dividing stream electricity resistance And connection, in the loop of the electric light of string what power supply and power supply load etc., the extraordinary big electric current of moment during to starting refrigerator and electric light etc. has metering function, has not only saved the electric energy, can also prolong the serviceable life of televisor etc.
5. the effect of reometer is arranged because of the light stream light fixture; so the user have a look light stream lamp brightness on the socket large and small, unglazed, when neglecting bright do not work suddenly (when the obstacle of loose contact is arranged) etc., the gate light that can understand remote control etc. is forgotten to have closed? which electric light does arenas wait be spoilt in the top? forget to pull out electric blanket etc. plug or find the obstacle that refrigerator can not auto stop etc.
This socket also has the function of identification electric equipment obstacle, as washing machine, electric fan, fan blower etc., when using this socket to supply the power supply of single phase motor winding, after start, electromechanical equipment is just trembled machine once, and can not run well, the light stream lamp is also bright, and the actuating section obstacle of motor has been described, and is moving at all as mechanical part, the mechanical load overload is described, or behind the mechanical part obstacle, blocked etc., also may be that the transmission adhesive tape of washing machine is disconnected or fallen etc.
The multifunctional power socket that embodiment 5. three-phase supply are used
Three-phase power socket is electrical equipment such as the threephase motor of medium and small power capacity and constant temperature oven, uses the plug component commonly used of three-phase supply equipment, and existing shortcoming is as follows:
1. function singleness; Can only be as the plug connector of three-phase supply and three-phase electric apparatus equipment, can not establish three power input voltage tables, three electric power output voltage tables, three reometers on one's body in the basis of socket, do not establish three power supply input indicators on one's body in the basis of socket yet, three power supply output indicators, three single-phase fuses.
Can not there be there input? so monitor and monitor three single phase poaer supplies of the three-phase supply in the socket at any time is there there output? whether fuse on-off? whether working current normal? to the common obstacle of the loose contact of what plug connector, just more difficult or can not be found at any time.
2. as supply with the three-phase supply on-load switch phase shortage of the three-phase supply of socket, or the fuse phase shortage of having no progeny and causing, or the loose contact of plug connector etc., all can make damage by phase shortage such as the threephase motor of socket power supply source or work undesired.
3. three characteristics of the middle term supply socket is that city's power supply is directly supplied with threephase motor etc., lack current-limiting apparatus, the electric current so the moment when starting motor or cold conditions heating equipment etc. surges, big what running current is doubly a lot, not only wasted the electric energy, also easily damage fuse and contact (for socket power, in the power load switch etc.) etc., plug connector contact, motor winding etc.
Purpose of the present invention is as follows:
1. on one's body the basis of socket; if have the light indication of the light indication of three single phase poaer supply input voltage tables and the effect of three single phase poaer supply output voltage meters, three reometer effects; the fuse of three single phase poaer supplies of overload and short-circuit protection, the molten lamp of the light of three single-phase fuses; can monitor and monitor the input and output of three single phase poaer supplies at any time, whether fuse disconnected? does power supply have electric current? not contacting or obstacle place such as loose contact of the switch of relevant electrical equipment etc.
2. the damage that can reduce or avoid common threephase motor phase shortage to cause.
3. can monitor and monitor the working properly and obstacle situation of electric equipments such as human eye is that can not directly see, remote control, device interior, reduce or avoid electrical equipment to damage, shorten maintenance and equipment off-time.
4. use this socket, can save electricity the energy, prolong serviceable life of electrical equipment.
5. use this socket, can reduce or avoid the accident of maloperation and error shock etc.

Principle of work is as follows:
The principle of work of present embodiment 5., basic identical with embodiment 3., and also also more simpler than embodiment 3., existing brief description is as follows:
At A, B, when the C end has the three-phase supply input, XD1, XD2, XD3 is bright, illustrate that existing three-phase supply has been imported in the socket, load R1 as three single phase poaer supplies, R2, the R3 nonoverload is also during not short circuit, RD1, RD2, RD3 constantly leads to, the output optical pressure lamp XD7 of three single phase poaer supplies, XD8, XD9 is bright, illustrate that existing three single phase poaer supplies have been exported in the socket, molten lamp XD4 is not worked by the RD1 short circuit because of light, the molten lamp XD5 of light is not worked by the RD2 short circuit, the molten lamp XD6 of light is not worked by the RD3 short circuit, load R1 as three-phase supply, R2, when R3 is respectively the single-phase winding of three of threephase motor, A phase power supply is through RD1, L2, behind the R1, become the loop with C phase power supply mutually with B, B phase power supply is the same with the logic of the principle of work of aforementioned A phase power supply with C phase power supply, make the G of socket, H, the I end has three-phase supply to export, the motor entry into service, during the elementary winding L 2 of A phase current by current transformer LH1, secondary winding L1 has the output of light stream lamp power supply, XD10 is bright, point out that A phase power supply has had electric current, in like manner, the light stream lamp XD11 of B phase power supply and C the light stream lamp XD12 of power supply mutually are also simultaneously bright, point out that three single phase poaer supplies have all had working current.
After A phase power supply load R1 overload or short circuit, RD1 is disconnected, A phase power supply is through the molten lamp XD4 of light, XD7, L2, R1, behind the XD9, become the loop with C phase power supply mutually with B, the working current that melts lamp XD4 because of light is few, be that internal resistance is big, when so the A phase current passes through XD4, land very big at the A at XD4 two ends and the voltage of D end, only lower slightly what A phase supply voltage and bright, point out that A phase fuse RD1 is disconnected, should in time cut off three-phase supply and maintenance, can avoid the damage of threephase motor phase shortage, because of the voltage landing of the G at R1 two ends and H end minimum, and stopped work, equally, the D at A phase power supply output optical pressure lamp XD7 two ends and the voltage landing of E end are also minimum, but after XD7 and XD9 series connection, can obtain B mutually with the C E of power supply and the power supply of F end mutually, so still can send the light indication littler than operate as normal brightness, simultaneously, because of RD1 has no progeny, A phase power supply does not have electric current to pass through current transformer LH1, so light stream lamp XD10 has not just worked significantly yet, the light indication of having no progeny as the RD3 of the RD2 of B phase or C phase changes, and the RD1 of the aforementioned A phase of the logical and of its principle of work has no progeny identical.
Because of current transformer LH1, LH2, LH3 go here and there respectively in the loop of what A, B, three single phase poaer supplies of C, the induction reactance of current transformer to the extraordinary big electric current of moment of starting motor or cold conditions heating wire etc., the effect of current limliting is arranged, so not only can save the energy of electricity, also can prolong the life-span of the contact, motor winding, heating wire, bulb etc. of fuse, switch.
The good effect of this socket is as follows:
1. before the start, indicating as the light of finding the three-phase supply input and output on the socket has after phase shortage or the start a single-phase molten lamp of light bright or when having a single-phase light stream lamp not work, and all should in time cut off the electricity supply and overhaul, and can avoid the damage of motor etc.
2. this socket is had any different and is indicated the function at obstacle place; After start, the indication of various light is all normal, but motor do not turn round, and the mechanical part obstacle of motor be described, and, stator bad afterwards as bearing and rotor have blocked etc.
When dragging the plant equipment of lathe etc., may be to have blocked behind mechanical load overload or the obstacle etc. as motor.
Therefore, use this socket, can shorten the time that maintenance and equipment stop production, reduce or avoid the damage of motor and plant equipment etc.
Does 3. obvious because of the indication of the light on this socket, can remind operator and maintenance people to understand socket at any time have? when particularly moving the power supply that uses three-phase socket, more can avoid the accident of maloperation and error shock etc.
4. the new varieties of a kind of product of supply socket have been opened.
Embodiment 6. optical pressure lamps, light stream lamp, the molten application Dan cross streams Dian Soldering machine of lamp on Dan cross streams Dian Soldering machine of light are Jin Shu Soldering knot equipment commonly used such as industry, and existing shortcoming is as follows:
1. existing Dan Xiangdian Soldering machine, small portable Dian Soldering machine particularly, do not establish power input voltage Biao ， Soldering knot electric power output voltage table and reometer (power light that has is not established), reason is the cost height, but also be subjected to AC transformer own easily, the particularly high-intensity magnetic field of the low-frequency choke coil of Tiao Zheng Soldering junction current influence makes the indication of instrument inaccurate, when having established instrument Ju Soldering knot workman than far away or ambient black exactly, also is difficult for maybe can not seeing clearly.
2. do not play electric arc when tying as Soldering, can not understand at any time whether electric Soldering machine has been broken? is which part bad? still is Dian Soldering machine output terminal Yu two feeder line loose contacts of Dian Soldering pincers? or the like.
3. except with soon, whether connect outside the protection ground wire, also lacked the further technical measures that can detect simple and practical again detection protection ground wire.
When being located at the molten lamp of optical pressure lamp of the present invention, light stream lamp, light on the Dian Soldering machine, just can monitor at any time with the various relevant situations of Jian Ce Dian Soldering machine, shown in Figure 10 as in the accompanying drawing 2, the meaning of figure Chinese words is as follows;
A, the input of B-AC power, 220V.XD1-power supply input optical pressure lamp, 2
The RD-fuse.Or melt or fusible core.20V。
The light of XD3-RD melts lamp.The K-power switch.XD2-power switch pilot lamp.
The LH-current transformer.The elementary winding of L1-LH.The L2-LH secondary winding.
The light stream lamp of XD4-supervision and Jian Ce Soldering knot output current.The JYB-step-down transformer.
The elementary winding of L3-JYB, 220V.
The secondary winding of L4-JYB, 70V, big electric current.
DK-is adjustable magnetic-core type low-frequency choke coil.XD5-Soldering knot power supply output optical pressure lamp, 70V.
H, G-Soldering tie power output terminal.The pilot lamp of XD6-supervision and monitoring and protecting ground wire
The step-down of R-XD6 and current-limiting resistor., neon lamp, 90～500V.
Principle of work is as follows;
When A and C end has power supply 220V input, when " breaking " as K switch place what, A end power supply by XD2 and XD1 after, become the loop with the B end of power supply, because of the working current of XD2 more littlely than XD1, so XD2 is bright, XD1 does not work, and points out the existing power supply input of A and C end, when not working for a long time, should cut off power supply, to avoid accidents such as maloperation and error shock for A and C end.
When K place what " led to " attitude, XD2 was not worked by the K short circuit, and XD1 is bright, pointed out that existing power supply is input to I and C has held.As Dian Soldering machine nonoverload again during not short circuit, RD constantly leads to, because of the molten lamp of light is not worked by the RD short circuit, illustrate that RD is working properly, A end power supply is through K, RD, L3, behind the L1, C becomes the loop with power supply, the H of L4 and G end output 70V Soldering knot power supply, when bright of XD5 such as Bu Soldering knot, the no-load current of JYB is little, so during by the little ， Zai of the brightness Soldering knot of the light stream lamp XD4 of L2 power supply, the power supply of F end, behind choking coil DK and H and G end De Dian Soldering bar, become the loop with G end power supply; when the big electric current when tying because of Soldering passes through choking coil, the voltage of establishing the induction reactance at F and H two ends lands when being 40V, at the H and the about 30V of G end output of output terminal, the brightness of XD5 has also reduced when Soldering ties, the power consumption of JYB is many, thus the brightness of light stream lamp XD4 also big ， You Shi Soldering when Soldering ties, sometimes Bu Soldering, thus the brightness of light stream lamp and optical pressure lamp XD5 also Sui the variation of Soldering knot situation and change, the indication of light has obviously been howed than the indication of instrument.
The principle of work of the optical pressure lamp XD6 of supervision and the effect of monitoring and protecting ground wire is as follows:
No matter during which termination city power supply it " live wire " of the D of L3 end or E end; the L3 middle part or the potential difference (PD) of J end and the G end of protection ground wire at middle part comparatively; keep about 110V forever; so when the protection ground wire being arranged as the G termination; the brightness maximum of optical pressure lamp XD6; as not connecing the protection ground wire; and the insulation between Dian Soldering machine and ground is when fine again; XD6 is little or do not have brightness substantially with regard to brightness; if though the G end does not connect the protection ground wire; but when still having certain resistance value between the metal shell of Tong Guo Dian Soldering machine or castor and ground; XD6 still has certain brightness; explanation does not meet safe requirement by dress and operation; because of XD6 uses the neon lamp identical with the test pencil characteristic; the resistor that resistance value is very big of having connected again; so when the G end does not connect the protection ground wire; stand in when contacting on the ground G end De Dian Soldering machine shell as the people; XD6 can not have brightness by having brightness to become; or it is big to become brightness for a short time by brightness, can understand the poor quality who does not connect protection ground wire or protection ground wire with Jian Ce Dian Soldering machine! But the people does not have electrical sensation or electric shock accidents.
Also can be on electric Soldering machine, use the branch platen press of resistance series connection, for optical pressure lamp XD6 working power, shown in Figure 9 as in the accompanying drawing 2, the logic of its principle of work, identical with the center tap method of aforementioned primary winding, but technology is simple, cost is low.

1. the device that lacks three single phase poaer supply input voltage tables, three single phase poaer supply reometers, supervision and three single phase poaer supply fuses of monitoring, the also Que Shao Soldering knot electric power output voltage table that has, so inconvenience or can not monitor duty with Jian Ce Dian Soldering machine at any time, cause phase shortage and work undesired easily, even damage.
2. because of the cost height of instrument, the AC transformer of shock-sensitive, easy Shou Dian Soldering machine itself, especially the induction of the high-intensity magnetic field of the adjustable choking coil used of Tiao Zheng Soldering junction current and interference and misregister, when being provided with instrument exactly, as the people apart from instrument during slightly far away or ambient black, the indication that also cannot or hardly see instrument clearly.
3. when the work of Dian Soldering machine is undesired, can not understand the reason of obstacle at any time, maintenance He the time that Dian Soldering machine stops production all long.
Purpose of the present invention is as follows:
1. Zai Dian Soldering machine in appearance, if the light that have three single phase poaer supply input voltage tables, three single phase poaer supply reometer, Soldering knot electric power output voltage table, can monitor and monitor three single phase poaer supply fuses is indicated, can monitor and monitor the working condition that three single-phase supply voltages, electric current, fuse, Soldering are tied power supply electric power output voltage etc. at any time.
2. during the operation irregularity of Dian Soldering machine, do not need to use Meter Test, 5～10 meters distant places of people Ju Dian Soldering machine can see the reason of obstacle, can shorten maintenance with the time that Dian Soldering machine stops production reduces or avoid the damage of Dian Soldering machine.
