Description
Technical field
The present invention relates to a kind of socket, specifically, relate to a kind of smart jack, belong to the low-voltage electrical apparatus field.
Background technology
Guarantee the power grid security economical operation, improve efficiency of energy utilization, be key and the pressing issues that China's electric power system faces.Undoubtedly, the terminal millions upon millions of users' that connect of electrical network demand side electrical equipment electricity consumption situation is to the power grid security economical operation, and improving efficiency of energy utilization has very significant effects, therefore to the necessary science of the management of power use of these electrical equipment, strictness, meticulous, reliable.Electrical equipment uses electric energy to insert socket by appliance plug and realizes that apparent, the socket that concerns of socket and electrical equipment is distribution or supplier of electricity, and electrical equipment is electricity consumption side, socket output electric energy, and electrical equipment input electric energy output function is user's service; Socket directly docks with electrical appliance, there is not any unnecessary link between them again, can draw an important conclusion thus, that is exactly: electricity consumption manages not only feasible but also is that cost is minimum the distributing function by socket to electrical equipment, the most effective, thereby be indispensable, irreplaceable, but an important restriction condition is arranged, if to be exactly socket only have distributing function and unmatchful distributing function carries out the function of intelligent control for that, remaining can't be to high degree of dispersion, vary, complicated millions upon millions of users' electrical equipment electricity consumption situation is carried out science, strict, meticulous, reliable management, because in a single day threat to life appears in electrical equipment when the time comes, during the electric fault of property safety, the only distributing function of socket can't open circuit, and therefore electric disaster is unavoidable.So power department is difficult to by the socket that distributing function is only arranged science, strictness, meticulous, reliable management be carried out in the electrical equipment electricity consumption all the time, have no alternative but to avoid the electrical equipment electricity consumption contradiction that varies, come a total cluster packing to handle: to register one's residence to hold at each household an ammeter record electrical equipment electricity consumption total amount is installed, no matter electrical appliance quantity what, specifications and models that ammeter box is following, all packing is handled, unified by the end ammeter record of registering one's residence, Electrical Safety can only be unified to be born by the modularization miniature circuit breaker of the model specifications such as DZ47 that are installed in register one's residence an end and a highway section.Since Here it is the own electricity, through 100 years of development, up to today, power department also rests on the basic reason of packing management to the management of demand side electrical equipment electricity consumption.
The electric disaster of touching/leak electricity the serious harm securities of the lives and property such as electric shock and short-circuit fire that constantly occurs repeatedly for these years, overstep tripping expansion power failure scope, heat high strength refrigeration on a large scale in season in midsummer and overload operation are damaged the bitter lesson of line facility can be heard without end, fully prove the uniform packing management of this power consumption and safety, can not effectively solve the power grid security economical operation, improve the problem of efficiency of energy utilization.Reason is not only clear but also simple, packing management itself is exactly a kind of extensive cluster management, only pay close attention to the result and do not pay close attention to details and the part that constitutes the result, therefore the result is not controlled, this one-tenth hundred million that just means millions upon millions of user and had to become tens household electrical appliance come down to doing things in his own way, each does what he thinks is right, the operation of a heap of a loose sand, it can not effectively be controlled by electric power system fully with electric process, so the blind area of electricity consumption, leak, black hole are many.The system that all can not effectively manage to output, how about can accomplish the stable, long-acting of system? the level notion of systematology is thought, system self evolves, the inevitable outcome of development is exactly that integral body is more and more senior, function is complicated more, level that constitutes and key element are also just many more, and inscape is many more, need set up Multistage Control mechanism more, otherwise system will fall into chaos.The packing management obviously is contrary to the level notion of systematology, so problem is constantly just not at all surprising repeatedly.Electrical network demand side user household electrical equipment in one's early years is few, and therefore bag is beaten for a short time, manages also easilier, and contradiction is not also given prominence to, but along with social progress, economic development, the electric utility great development, household electrical appliance are growing on and on, the packing that holds on can be to wrap to beat bigger and bigger only, and black box is more and more black; Global warming, extreme weather get more and more, and the common people require constantly to increase to quality of life, and power consumption only can significantly increase; All these have increased the uncertainty of power system operation.Therefore the uniform packing management that has adequate cause to assert following this power consumption of current ammeter box and safety, to have swepting the globe now and throughout the country energy-saving and emission-reduction, the life that people-oriented is sovereign safe, and is obviously outdated.Obviously, to the millions upon millions of users' of demand side electrical equipment distribution management each electrical equipment that not only will become more meticulous, and to the factor that all of every station terminal electrical equipment of the distribution management that becomes more meticulous relate to power consumption and safety be managed, it is integration Management, could carry out science, strictness, meticulous, reliable management, the shade that makes electrical network thoroughly walk to go wrong to the electrical equipment electricity consumption.And when traditional electrical network is further developed into that structure is more complicated, during the intelligent grid of more perfect functions, if also hold on the packing management, even more serious consequence is well imagined.
Though now had some to have the socket of certain controlled function; as touch/earth leakage protective, overcurrent protection, anti-surge protection socket; power supply changeover device in addition economizes on electricity; but their common two aspect defectives that exist; the one, insufficiency; the 2nd, lack crucial short circuit protection and overstep tripping function not, so their scope of application is limited.The reasons are as follows: the one, their contact design does not reach the contact design standard of circuit breaker.Existing contact design has all been applied mechanically conventional domestic switch standard, therefore contact pressure is generally too small, cause contact resistance bigger, as long as tail circuit generation first short circuit fault, dynamic/static contact will stick together under the thermal effect effect of short circuit current, scaling loss, contact is not also because of separating the serious consequence that very likely causes electrical fire, therefore the vitality of their existing defencive functions is just very fragile, all the time be in extremely unreliable state, therefore short trouble all can accessiblely spread to the electrical network depth by socket at any time, causes wider power failure and increases the weight of the extent of injury of electrical fire; The 2nd, they all are to rely on analog circuit to the controlled function of distribution, do not adopt digital circuit and microprocessor, lack of wisdom chemical control system, can not possess short circuit protection overstep tripping preventing function, therefore short circuit is in case take place, electric current just can rise violently rapidly and surpass the instantaneous protection setting value of higher level's circuit breaker, makes the instantaneous release action and overstep tripping; The 3rd, the control command that their actuator sends control device does not possess the effective of microsecond (μ s) magnitude actuating precision and accurately carries out function.The prior art routine, the traditional final controlling element link with compositions such as connecting rod, snap close, energy supply systems is many, the cumulative movement tolerance big and response slowly, low, response time of poor controllability, efficient generally wants a few tens of milliseconds, the dispersiveness of moving in addition is also bigger, for AC controling signal even greater than 10 milliseconds, even the employing dc operation, the dispersiveness of operate time is also at Millisecond.
In sum, power department finally protects the not demand side terminator socket of overstep tripping function because of the short circuit that lacks intelligent control, so can't be to high degree of dispersion, vary, complicated millions upon millions of users' electrical equipment electricity consumption situation implements science, strictness, meticulous, reliable management, handle and have no alternative but packing, know that adverse consequencess such as energy consumption and safety can beat bigger and bigger and be on the rise along with bag perfectly well, but do not have better solution yet, can only let matters drift.

1, the said smart jack technology carrier of the present invention is exactly the extremely small space of conventional socket, and will be in that so small space lining office is brand-new, perfect, compact, reasonable, and each functional structure is docked clog-free overall structure and do not conceived
1) there is the cylindrical tube (41) of perpendicular connection at the said smart jack support plate of the present invention (4) back side, the inner chamber of cylindrical tube (41) runs through positive this distinguishing characteristics of support plate (4), make originally be supported the isolated socket of plate (4) up and down small space got through fully, the said smart jack of the present invention moving (11) unshakable in one's determination is a passage with the inner chamber of cylindrical tube (41), enter the small space top from the small space below, the narrow and small passive iron core in space up and down (11) of socket is communicated with, contact pressure is adjusted spring (12), moving contact part (13), fixed contact parts (14), the testing apparatus that contains testing button (151), the resetting means that contains reset button (161) all can be compact and orderly layout in the positive top of support plate (4), coil (10) then layout in the lower rear of support plate (4), with the circuit board that electronic devices and components are installed on it (8) interface, all layouts are in perfect order, do not clash and disturb, and each correlation technique feature butt joint is accessible, complements each other, on function, support mutually.
2) cylinder of moving (11) one end maximum gauges unshakable in one's determination is installed in the inner chamber of support plate (4) below cylindrical tube (41), when switching on, set up electromagnetic connection with the coil (10) that is installed in cylindrical tube (41) outside, its end face is relative with the following permanent magnet (92) that is installed in end box (3), and electricity keeps the magnetic contact; Be positioned at and on the cylindrical ladder shaft shoulder of moving iron core (11) of cylindrical tube (41) inner chamber of support plate (4) contact pressure be installed and adjusted spring (12), remainder passes moving contact part (13) endoporus that is positioned at support plate (4) top, makes moving contact part (13) and fixed contact parts (14) constitute closure or released state; On the cylinder at moving (11) other end minimum diameter unshakable in one's determination place sucker (111) is installed, can sets up the magnetic contact with the permanent magnet (91) that is installed on the small panel (2); The bi-stable permanent magnetism operating mechanism of having formed a complete smart jack indispensability thus, this permanent-magnet manipulating mechanism efficiently solves first (not reaching the contact design standard of circuit breaker) described in the above-mentioned background technology and the 3rd problem (do not possess the effective of microsecond (μ s) magnitude actuating precision and accurately carry out function), that has effectively cracked the intelligentized microsecond of restriction socket (μ s) magnitude actuating precision effectively and accurately carries out the function bottleneck, is the necessary structure that realizes the said smart jack of the present invention.
3) below that control circuit light current parts such as power electronic device above the circuit board (8) of electronic devices and components, single-chip microcomputer all concentrate on support plate (4) is installed on it; Forceful electric power input, output block that right sleeve (51), left sleeve (52), contact pressure are adjusted spring (12), moving contact part (13), fixed contact parts compositions such as (14) all concentrate on the top in support plate (4), the topology layout that forceful electric power and light current separate, it is minimum that electromagnetic interference is reduced to, and electrical security and reliability are higher;
4) circuit block of real-time detection apparatus (7), testing apparatus and resetting means all is installed in the back side of support plate (4), make full use of the confined space in the socket, can realize accessible butt joint by lead (510) and (520) between the corresponding input on the output of checkout gear (7) and the circuit board (8);
2, control assembly circuit and execution unit and resetting device hight coordinate, substitute the other side's sophisticated functions structure with design feature mutual supplement with each other's advantages separately, with simple structure, both ensured the high-performance that coordination and interaction are integrated, make structure more succinct, compact and highly reliable again, obtain to integrate the remarkable result of back 1+1＞2.
1) moving (11) unshakable in one's determination motion makes contact (131) separate with contact (141), in the power supply of cutting off the electricity supply, also cut off circuit board (8) and gone up the control assembly DC power supply of forming by light current components and parts, power electronic device, if avoided filter capacitor after triggering controllable silicon, can not in time stop to trigger to cause controllable silicon out of control, destroyed the consequence of the said smart jack operate as normal of the present invention.Though other circuit solution is arranged, can be very complicated.And simple structure of contact terminal cleverly can the replace complex circuit solution;
2) resetting means that contains reset button (161) comprises contact (162) and contact (163), contact (164) and contact (165), and they are connected in the reset circuit.From Figure of description 8 as seen, in case it is just closed to press reset button (161) contact (162) and contact (163), power supply is just connected, moving (11) unshakable in one's determination just can drive the normally open contact (131) and contact (141) closure of contact component (13) and fixed contact parts (14), energized, and meanwhile, originally closed normally closed interlock (164) then separates with contact (165), in the time that manual reset can being avoided, give the long-time heating power that coil (10) brings even the drawback of scaling loss because of pushing contact (162) and contact (163) for a long time;
3) general on the coil rack of prior art all around two opposite coils of rotation direction, so that drive moving (11) unshakable in one's determination from two rightabouts, but the said smart jack of the present invention has only adopted the coil (10) of a rotation direction, it also can drive moving (11) unshakable in one's determination from two rightabouts, saved a coil for this reason, had more the space, its principle is utilized the unilateral conduction of diode (84) and controllable silicon (82) exactly, when having electric current to pass through in the coil (10) at every turn, the current channel that a direction can only be arranged, walk diode (84) and just can not walk controllable silicon, vice versa.Diode (84) place circuit and controllable silicon (82) place circuit may be worked at no time simultaneously, a circuit working can only be arranged at every turn, do not disturb and the damage components and parts so can not produce, and in case press reset button (161), the moment of energized, closed originally normally closed interlock (164) then separated with contact (165), therefore (can not act on the voltage on line voltage and the circuit board (8) on 10 simultaneously, damage components and parts at coil so can not cause the circuit disorder by rectification circuit and the common DC power supply of forming (81) of capacitor.Therefore it is fully feasible saving a coil.
In sum, the said smart jack of the present invention is with the structure integrated innovation, with mechanical organ function replacement part electric function, coordination and interaction, complement each other, go after profits and advoid disadvantages, effect is remarkable: broken the DC power supply rectification circuit control silicon controlled that filter capacitor can not be used on (81) and used convention, thereby guaranteed to trigger accuracy constantly; Avoid the infringement of electric current when resetting to coil (10); Realize the electrical control of permanent-magnet manipulating mechanism bistable state with a coil, thereby save a coil, invention of design concept and organization plan that breaks traditions especially, the said smart jack of the present invention makes high-performance, high reliability and the harmony in small space of brief structure, has fully reflected the remarkable synergy of integrated innovation 1+1＞2.
3, possessed the essential circuit breaker function of disjunction short circuit current:
According to the circuit breaker design requirement, can adjust spring pressure and adjust screw (141), guarantee many to contact contact simultaneously basically, also can obtain excess of stroke e, guarantee the prerequisite contact terminate pressure of disjunction short circuit current, like this when short circuit current passes through contact, contact just can be not little because of contact pressure, cause contact resistance big, and excessive heating adhesion, scaling loss, failure phenomenon appear, during circuit generation circuit, have only at first to withstand the test of short circuit operating mode, just have and realize that second step of overstep tripping may not.
4, circuit board (8) has upward been formed the typical electronic operating mechanism by power supply (81), controllable silicon (82), coil (10) that rectification circuit and electric capacity are formed;
Relying on power electronic device controllable silicon (82) control (triggering) power supply (81) discharges to coil (10), produce pulsed magnetic field, bistable-state permanent magnet mechanism moving (11) unshakable in one's determination is produced an explosive force, motion under the synergy of last permanent magnet (91) and following permanent magnet (92), finish the conversion of electric energy to mechanical energy, output promotes moving contact part (13) and does disjunction or the required active force of closing motion.Practical application example according to bibliographical information and 35KV vacuum switch bistable-state permanent magnet mechanism, bistable-state permanent magnet mechanism triggers power supply (81) from controllable silicon, and discharge begins to moving (11) unshakable in one's determination motion to coil (10), and the overall delay that produces arc gap between contact can reach the actuating precision of microsecond magnitude.
5, single-chip microcomputer (83) Applied Digital circuit has been realized Based Intelligent Control; it is a back yard industry control microcomputer with cpu system; therefore can realize very complicated defencive function and protective feature thereof by programming; take precautions against necessary " current limliting " function for short circuit protection overstep tripping, utilization has the single-chip microcomputer of logic analysis function and more easily realizes.
The tail circuit of normal operation, though load has fluctuation, but can not alter a great deal suddenly in the short like this time,, hinder electric current for some reason and increase suddenly if therefore at a time be short-circuited at a power frequency period, certainly lead to jump-value of current, because microcomputer has memory function, is easy to compare the sudden change amount in sampling process, therefore can set a sudden change amount, as long as collect this sudden change amount, single-chip microcomputer is just started working and send the instruction of cutting off the electricity supply after certain time-delay.Just respond when need not as the traditional protection device, must wait jump-value of current to rise violently maximum, so the said smart jack of the present invention just can be realized easily to required " current limliting " controlled function of short circuit protection overstep tripping strick precaution.
According to document record, electronics actuating overall delay t
3=t
1+ t
2+ t
3, t wherein
1Be circuits for triggering time delay, t
2Be coil magnetization time delay, t
3Be electromagnet motion time delay, under the condition of utilization single-chip microcomputer, various systematic errors can overcome by the Computer Compensation in the single-chip microcomputer, so the actuating of bibliographical information electronics might reach the high actuating precision of microsecond magnitude fully.Detect the short circuit sudden change from real-time detection apparatus (7) and measure (11) unshakable in one's determination drive moving contact part (13) and several same fixed contact parts (14) disjunction mounted thereto, cut off the physics contact of circuit, the overall delay of whole process is in the microsecond order magnitude range.This is that the automation controlling organization of any analog circuit so far can not be accomplished, has solved second bottleneck described in the said smart jack background technology of the present invention " lack of wisdom chemical control system can not possess short circuit protection overstep tripping preventing function "
Because what pass through in coil (10) is the direct current of the good wave filtering effect of controllable silicon conducting, therefore coil (10) presents minimum induction reactance, electric current is very big, current instantaneous value is not influenced by the time dependent sine wave of alternating current, therefore control signal has controllability preferably to moving (11) unshakable in one's determination, promptly moving (11) unshakable in one's determination are controlled to the response time of control signal, can obtain the effect of " effectively carrying out with accurate ".
Put down in writing according to document, after short circuit current takes place, need just can reach maximum through 10ms, higher level's circuit breaker DZ47-C10 series modularization small-sized opening circuit of installing with the end of registering one's residence is example, according to the GB6829-1995 national standard, prospective short circuit current is 500A, by the linearity processing of rising violently, the speed of rising violently of short circuit current is 50A/ms, therefore short circuit current rises violently and moves the time that protection setting value 100A needs 2ms at least higher level's circuit breaker wink, and the said smart jack of the present invention begins to detection from the sampling of transcient short circuit time sudden change amount, control, carry out, total time-delay that contact produces arc gap is no more than 1ms, and institute's higher level circuit breaker can not trip in the 1ms after short circuit takes place certainly.The product national standard of DZ47-C10 modularization miniature circuit breaker " residual current action breaker of the band overcurrent protection of GB16917.1-2003 family expenses and similar applications " regulation; if＞10In; promptly＞the short circuit current instantaneous value of 100A; require release in＜100ms, to trip; the trip coil of " higher level " circuit breaker DZ47-C10 modularization miniature circuit breaker is the alternating current actuating; the document record, only the dispersiveness of its operate time is just greater than 10ms.Therefore 2ms does not consider with regard to the minimum or perhaps small probability event of possibility of tripping operation, is that sufficient theoretical foundation is arranged so smart jack short circuit of the present invention protection overstep tripping preventing function is succeedd.
The said smart jack of the present invention adopts single-chip microcomputer (83); can be according to the required best operating characteristics of relaying protection; all electric faults that comprise short trouble were carried out effectively handling with accurate in the time interval of microsecond magnitude; send control command; and permanent-magnet manipulating mechanism can carry out effectively carrying out with accurate to instruction in the time period of microsecond magnitude; the two combination; just can obtain high relaying protection performance index; can satisfy State Grid Corporation of China to strong electrical network under various disturbances, requirement that can both safe and reliable operation.
6, the smart jack integrated use various arc extinguishing means, so arc quenching effect is good:
The smart jack that the present invention is said; because spring pressure is adjusted the existence of screw (141) and the reference for installation of fixed contact parts (14) all is support plate (4) front; therefore can easily same height be adjusted in the fixed contact position of fixed contact parts (14); there be certain manufacturing with fixed contact parts (14) in moving contact part (13) even if constituted; alignment error; also can be basically can double-breakpoint structure closed simultaneously or that disconnect simultaneously bridge contact; can satisfy the requirement of State Standard of the People's Republic of China GB6829-1995 " the general requirement of RCD " preferably about " moving contacts at different levels with two extremely above RCDs ... no matter in manual operation or when threading off automatically should be closed simultaneously basically or disconnect simultaneously ".Has improved burning voltage, shortened the arcing time, also just shortened break-time, so the multibreak arc quenching effect is good, moving contact (131) and fixed contact (141) but between needn't reach the just blow-out of safe air gap of 3mm, realize electric disjunction.
Electric arc and Electric contact theory are pointed out, has higher contact breaking speed, the initial breaking speed height of contact particularly, can avoid electric arc long initial dead time, effectively increase breaking capacity, because the existence of excess of stroke e, contact pressure is adjusted spring (12) and has been quickened moving iron core (11) movement velocity in the separation process, more helps arc extinguishing.
7, has open expanding function
Because microcomputer itself is exactly a high-performance, multi-functional computer; therefore be to realize terminal networkization easily under current prior art condition; therefore the microcomputer technology principle can make the protection of terminal socket collection, control, measurement, data communication integrated; both can satisfy intelligent grid and overcome disturbances such as short trouble; guarantee the strong quality requirements of power grid security reliability service, can satisfy the two-way flow requirement of carrying out electric energy, information between intelligent grid and the user again.
8, the said smart jack theory of the present invention has overcome traditional prejudice
Short circuit protection overstep tripping is taken precautions against the reason of this hard nut to crack, the tradition that comprises experts and scholars explains it is " setting value that the short circuit current of subordinate's circuit breaker has surpassed the instantaneous protection of higher level's circuit breaker very greatly ", and the said smart jack of the present invention adopts the technological means of " current limliting ", at traditional thinking, reverse thinking, the scheme that increases with limiting short-circuit current solves problem, just adopt means that Based Intelligent Control and permanent magnetic operating modern technologies combine with the quick disjunction faulty circuit of sufficiently high breaking capacity in short trouble rudiment moment, still do not have enough time to rise violently above before the instantaneous protection setting value of higher level's circuit breaker at short circuit current, just because of being descended rapidly by disjunction, the instantaneous protector of higher level's circuit breaker can not be moved, solved that people thirst for solving between more than 100 year since the own electricity always, but the short circuit protection overstep tripping of failing all the time to succeed is taken precautions against long-standing technical barrier.
Though said smart jack Based Intelligent Control of the present invention and permanent magnetic operating all are prior arts, but never the people expected they are integrated in the existing narrow and small socket space, one of reason is that socket is simple, with low content of technology, degree of homogenization height, tradition prejudice makes people can not go to think how to improve its technology content, allows it have new work to be; Former two is that total arrangement intelligent device difficulty is big in small space therefore, and the many difficulty of interface are bigger, at forceful electric power, light current, microelectronics, control, in the multidisciplinary technological synthesis integrating process such as execution, the physics conflict of difference in functionality and structure thereof, technical contradiction is too many and too difficult to be coordinated, socket industry technology threshold is low, be difficult to set foot in, though therefore at high pressure, the middle product that mature technology is arranged in the relaying protection field of pressing is used, but arrived the low voltage product field, particularly to real meaning electric terminal rather than register one's residence the end ammeter box circuit breaker, how in the socket small space the inside that is positioned at electric terminal to relating to above-mentioned multidisciplinary technological synthesis, carry out unprecedented integrated innovation, difficult especially, therefore challenge the more beats a retreat in the face of difficulties; Former therefore three be integrate innovations structure bottleneck where, unclear, so smart jack is a low-voltage electrical relaying protection blank always.The said smart jack support plate of the present invention (4) is provided with cylindrical tube connected vertically (41) and cylindrical tube (41) at its back side inner chamber runs through this unprecedented distinguishing characteristics of support plate (4), broken through integrate innovations structure bottleneck, make small space no longer be cut apart, but be connected up and down, no longer include the difference on ceiling and floor, originally narrow space is fully utilized, big for breaking through the total arrangement difficulty, the big very space of preciousness that obtained of interface difficulty, particularly each technical characterictic of technical scheme necessity supports one another on function, complementary, greatly simplify the structure again, in narrow space, obtained unforeseeable technique effect finally.
