Description

A kind of quick-break lightning protection power source in duplicate supply loop

Technical field

Belong to electronic technology field.

Background technology

Power supply is the key of each electronic product, the quality of power supply directly affect entirety performance, electronic product day crescent Different, need the function of power supply also to tend to reach perfection and could meet the requirement of product, so there being the most outstanding regulated power supply at present. Although but the power supply of these voltage stabilizings has many good qualities, needs with rapid changepl. never-ending changes and improvements still can not be met.

Once multiple product about security personnel's equipment had been applied for such as this enterprise.The product of these equipment is to the requirement of power supply the most very Height, overcritical degree will significantly larger than ordinary electrical home appliance, be inefficient by traditional design.Reason is as follows:

One be power supply be often electrical equipment, the most troublesome keypoint part, the most such to ordinary electrical home appliance.And to being furnished with electric power storage The product in pond is all the more so, because during with accumulator, and the most only load power source, add again the charging current filling accumulator, If accumulator electricity consumption is too much, initial charge stream is very big, thus more exacerbates the load of power supply, thus is easily damaged.

Two is the ordinary electrical home appliance same day at thunderstorm season, can pull out power supply prevention, in the needs used time, (if desired for seeing electricity Apparent time) because being easily alerted, can recover immediately, user is expected.And series products of ensuring public security is the most highly difficult, because dialling Behind power down source, being difficult to intuitively remind, because in the life of high rhythm, forget about that these things are possible, now its protection function is just Malfunctioning, produce security personnel's blank.If user is forgotten to recover, then security personnel will be in security personnel's blank for a long time.And present stable state collection Become in lightning protection, the most weak, as generally input ceiling voltage is only about 30 volts.

The particularity importance of three products being because security personnel, it is therefore necessary to have when design and adapt to electrical network change Wider, key benefit reason one is when voltage ripple of power network, will not originally penetrate integrated regulator and cause damage.Reason Two are, civil power relatively low or relatively high time can normal voltage stabilizing, do not result in the malfunctioning of protection function.Reason three is to make security personnel Product can have bigger use space.

Four is that security personnel's series products necessarily joins accumulator, and the maintenance of accumulator has higher requirement, wherein charging voltage It is worth different with place value.If load request voltage stabilizing is pressed in voltage stabilizing, then can not meet the requirement of charging, if by the voltage of charging As requiring, then load will be higher than normal required voltage for a long time.This is difficult point one.Difficult point two is if there being battery discharging system System, inevitable is formed or door power supply mode load with mains-supplied system, therefore both be loaded with or the circuit of door character. During battery discharging, most of time is often to save the standard value of 2 volts, and along with discharging, this value also to decline, the therefore output of accumulator Voltage drop is of great value, if or the pressure drop of circuit of door character excessive.The normal standard of deviation then loaded strengthens.Therefore use Any measure makes accumulator not produce too much pressure drop when electric discharge, becomes difficult point.Difficult point three is Set of system, and be that battery system is powered during without civil power, conversion between the two is to automatically switch, the most how could be real Now change scientific.Difficult point four is how to form two parts to power and be independent of each other each other, is i.e. when accumulator breaks down, no Mains-supplied system can be affected, otherwise do not interfere with battery system during mains-supplied system failure.Difficult point five, some data carry Going out and make to switch with relay, this scheme has multiple deficiency, and wherein the point of an important deficiency is power consumption, and difficult point six is, some Scheme cost is too high, is not suitable for the universal of product.

It is further described below:

One, Alternating Current Power Supply unit of the present utility model be designed with 3 measures, therefore have the strongest fan-out capability, meet and hand over Stream power supply unit, the double heavy duty needs of accumulator level, highly reliable.

Due to the Alternating Current Power Supply unit in this utility model, it is the main time to loaded work piece, uses and penetrate with output, expand The big output of audion, load capacity is very strong, is in " big horse " and draws the state of " dolly ".Thus improve Alternating Current Power Supply The reliable life of unit, two is that the emitter stage of two AC voltage-stabilizing audions has all gone here and there overcurrent protection resistance, can make two pipes loads Than carrying equilibrium, two pipes are difficult to imbalance and damage.Three is the current limliting having voltage stabilizing audion, thus forms AC voltage-stabilizing audion and protect Protect.So reliability is high.Three is that the voltage stabilizing to base stage has special design.

Two, this utility model has the explanation of the strongest overvoltage protection ability.

Having good anti-overvoltage protection explanation: have multi-stage protection unit, rectification output end is to when being connected with high voltage transient, anti- The lightning protection stabilivolt (in Fig. 1 2.0) that thunder relay (in Fig. 1 2) is connect suctions through, and its corresponding normally-closed contact disconnects, to rear class Form protection quick-break, therefore to protected effect of being struck by lightning, form the protection of the lightning protection first order.The principle that this protection is formed is, right Rear class is cut off rather than short circuit, so there being good effect, at the lightning protection of numerous equipment of many Compact Power Plants, just It is to use this fast tripping protection.Due to the audion of pulse charge unit Yu Alternating Current Power Supply unit, have employed high countervoltage triode, Its back-pressure can >=300V, anti-reflective pressure energy power strong (integrated only 35 volts of general three-terminal voltage-stabilizing), so forming two poles protections.Again due to The base stage of two AC voltage-stabilizing audions have employed special design, have employed overvoltage protection resistance (in Fig. 2 5.2), becomes Dropping resistor, and in addition have the combination of two stabilivolts, can inrush current prevention, it is ensured that base stage is basicly stable, hereby it is ensured that basic Output is stable, so forming third level lightning protection.Owing to Alternating Current Power Supply unit can export more stable voltage, to also rear class energy Serve good protective effect, so integrated circuit lightning protection properties is strong.

Wherein two the rectification outputs of a termination of the two ends of the line bud of lightning protection relay, the other end takes over control thunder stabilivolt to ground Line, because the voltage stabilizing voltage of stabilivolt several volts higher than the output of two rectifications, the most in normal state, lightning protection stabilivolt will not be by Puncturing, the double-throw contact of lightning protection relay communicates with normally-closed contact, that is to say that the input of rear class is all equivalent to be connected on rectification defeated On going out, and once having thunderbolt overvoltage, after overvoltage exceeds the pressure voltage of lightning protection stabilivolt, lightning protection stabilivolt is breakdown, and lightning protection continues Electrical equipment adhesive, its double-throw contact disconnects with normally-closed contact, the input dead electricity of rear class, thus protects late-class circuit.

The benefit using such circuit to form switching behavior lightning protection is, the pressure above hectovolt that is typically all of anti-thunder tube, tens The very difficult of volt is looked for, for the general such low-voltage of 12V, 24V, 36V, the most incorrect with the anti-thunder tube of hectovolt , and the voltage stabilizing voltage of stabilivolt selects very well, within the scope of the lowest, and the reason of relay can be used to be, relay Thunderbolt rapidly, can quickly be responded by device response, so selecting lightning protection relay and lightning protection stabilivolt to collectively constitute switch Lightning protection forms protection to circuit.

Three, the explanation of third level lightning protection particular design.

1, the reliable reason of output voltage: when normality works, because the breakdown potential of backup voltage stabilizing branch road (in Fig. 2 5.6) Pressure is higher than the voltage stabilizing value of work voltage stabilizing branch road (in Fig. 2 5.8), by work voltage stabilizing branch road clamper.Thus backup voltage stabilizing Zhi Luji This no current, is in " resting state branch road ", when the voltage stabilizing branch road that works is because being damaged to open circuit, (for the common form of fault), Backup voltage stabilizing branch road will automatically engage work, and owing to the voltage of two branch roads will not differ greatly, its error will not have a tremendous difference, But but substantially increase reliability.

2, the reason that overvoltage protection ability is strong: when there is thunderbolt and shoving, because one is that two AC voltage-stabilizing audions are for high Back-pressure pipe is so being difficult to infringement, and two is that the semifixed resistor that work voltage stabilizing branch road is connected increases, when the voltage of this branch road exceeds standby During the voltage stabilizing value of part voltage stabilizing branch road, backup voltage stabilizing branch road is also switched on, and becomes two-way and shoves passage, decreases work voltage stabilizing branch road Electric current, thus improve the reliability of stabilivolt.Three are because above-mentioned reason, have limited the highest of AC voltage-stabilizing transistor base Voltage, thus ensure that ac output voltage.

Four, Alternating Current Power Supply unit has the explanation of excellent performance.

One is output voltage stabilization, and two is to have overcurrent protection, and the reason producing protection is when current is excessive, Alternating Current Power Supply The pressure drop of the overcurrent protection resistance that unit transistor emitter is connected increases, when the Alternating Current Power Supply exceeding Alternating Current Power Supply unit limits During the threshold value that stream indicates, the base flow shunting of AC voltage-stabilizing audion, thus cause emitter current to reduce.Three is to have overcurrent protection Display, working service is convenient.

Five, there is wider mains input voltage explanation.

1, the scope that civil power is wider can be operated in.

Circuit is high-power high countervoltage triode, the back-pressure >=300V of its colelctor electrode, so rectifier transformer secondary end Voltage can be suitable higher, when therefore civil power is relatively low, the voltage of rectifier transformer secondary end remains to meet wanting of device Ask.And when therefore civil power is higher, its rectification output is still not above 300 volts, thus it is unlikely in Alternating Current Power Supply cell level Penetrate and damage with pipe.So this utility model can be operated in electric hypodynamic place, and in the too strong place of electric power also Without compromising on.

2, be difficult to when unexpected fluctuation occurs in civil power damaged.

Also because of above-mentioned reason, so when civil power unexpected fluctuation, will not damage easily.

The explanation of six, independent charge circuit feature.

It not in high-grade pressure stabilizing device, it is difficult to ensure that there is the accumulator of floating charge with civil power is powered simultaneously, there is height The unification of degree.This measure have employed special design, by completely separable with load circuit for the most supporting floating charge loop, thus tool There is good advantage.Now as a example by load needs 12 volts, if the accumulator of adapted 12 volts.Then during accumulator floating charge, need About 13.8 volts, if not designing special circuit, then when civil power has electricity, power output end is about 13.8 volts for a long time, and this is right The load only needing 12 volts is unfavorable.If power end output is adjusted to 12 volts, though load request can be met, but departing from accumulator Needed for floating charge 13.8 volts.Accumulator floating charge and discharge cell is devised for this native system.Its floating charge principle is that civil power has electricity Time, the output of bridge rectifier one has electricity, through pulse charge unit, then returns to DC power supply unit rectification through accumulator Ground terminal, be also the negative terminal of accumulator, thus form floating charge independent loop, according to kirschner law, and the experiment of circuit, this Floating charge loop is self-existent, does not interfere with each other the current supply circuit of load with Alternating Current Power Supply unit, and Alternating Current Power Supply unit is to negative The current supply circuit carried is the output electric current of Alternating Current Power Supply rectification, through Alternating Current Power Supply unit to load, is then return to ground wire, namely It it is the earth terminal of Alternating Current Power Supply rectification.

Floating charge simultaneously have employed the oscillation form charging of pulse, it is achieved that to the charging of accumulator science it is thus possible to very The life-span of the prolongation accumulator of bigization and capacity.

The feature of this unit is to be not only a clapp oscillator, can adjust frequency in the line.

Its principle forming vibration frequency-adjustable is, by the outfan of agitator (in Fig. 2 10.1) and in-phase end institute Comparison resistance (in Fig. 2 10.12) partially under comparison resistance (in Fig. 2 10.11) and pulse partially in pulse even, becomes homophase The comparison voltage of end, also becomes threshold voltage, when the outfan of agitator is high-order, by pulse adjustable resistance (in Fig. 2 10.13) series circuit with pulse adjustable limit value resistance (in Fig. 2 10.15) charges to pulsed capacitance (in Fig. 2 10.16), When being charged to threshold value, outfan cataclysm is low level, and at this moment pulsed capacitance is by pulse adjustable resistance and pulse adjustable limit value resistance Series circuit discharge to outfan, when current potential is less than in-phase end, oscillator output end becomes high-order, starts second round Charging process.Pulse adjustable resistance defines frequency of oscillation coarse adjustment, can adjust frequency, and pulse is adjustable, and limit value resistance is that pulse can Adjust the restriction of resistance minima.

When agitator is output as low level, and floating charge audion (in Fig. 2 8) turns on, start to charge to accumulator, and work as floating charge When agitator is output as a high position, floating charge audion ends, and accumulator stops charging, now by trickle resistance (in Fig. 2 7) to storage Battery provides the trickle maintained.

Negative phase end at failure of oscillation device (in Fig. 2 10.2) is connected to failure of oscillation and relatively goes up inclined resistance (in Fig. 2 10.21) and failure of oscillation Under Bi compare, inclined resistance forms the threshold voltage of failure of oscillation device negative phase end, and its principle is, when accumulator floating charge to this threshold value, and failure of oscillation Device output high pressure, allows the blocking of oscillator, agitator export a high position by failure of oscillation diode (in Fig. 2 10.23), stops to electric power storage Charge in pond.

Seven, civil power and accumulator duplicate supply explanation, its power supply trend is as shown in Figure 3.

When mains sometimes, Alternating Current Power Supply rectification output high pressure, after the Alternating Current Power Supply unit, enter load unit Power end, conversion and control audion is triggered by conversion and control resistance, and therefore by the earth terminal of load unit, load current is through turning Changing and control the colelctor electrode of audion to emitter stage, because changing the grounded emitter line of audion, being therefore returned to ground wire, i.e. It it is the earth terminal of Alternating Current Power Supply rectification.

When mains without time, Alternating Current Power Supply rectification is without output, and Alternating Current Power Supply unit is without output, but now accumulator is to negative Carrier unit is powered, and electric current is after load unit, through direct current conversion controllable silicon (in Fig. 3 13.1) connecing to DC supply commutation Ground end, is i.e. the negative terminal of accumulator, completes power supply.

Eight, the principle explanation of controllable silicon converting unit.

When mains sometimes, Alternating Current Power Supply rectification output high pressure, conversion and control audion (in Fig. 2 12.2) is triggered, Producing base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is, exchange Power-supply rectifying positive pole, through control unit transistor base to ground, collector current loop is, the output warp of Alternating Current Power Supply unit Overload unit enters the colelctor electrode of conversion and control audion and then arrives ground.Now direct current conversion controllable silicon is without trigger voltage, also It is i.e. no Anode current, for off-state.

When without mains, Alternating Current Power Supply rectification without electricity, does not produce base without output, conversion and control resistance (in figure 12.1) Stream, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the voltage of accumulator is through overload list After unit, by direct current transition trigger resistance (in Fig. 2 13.2) trigger direct current conversion controllable silicon (in Fig. 2 13.1), now return Lu Shi, the anode of accumulator enters load unit through DC-isolation diode (in Fig. 2 9.1), then after load unit Enter direct current conversion silicon controlled anode, direct current conversion silicon controlled negative electrode enter the earth terminal of DC supply commutation, namely It it is the negative pole of accumulator.

This utility model has a following significant advantage after implementing:

The quality of power supply, directly influences the performance of entirety.Power source performance is good, then overall performance is good.The one of particular importance It is that important equipment is generally equipped with Accessory Battery, as its scientific maintenance directly not affected the life of storage battery with reliable Property, it would be possible to become a kind of new trouble point, if if two is that the power supply parameter of supporting power supply is deposited with the power supply parameter of civil power Leading in difference, will directly affect electric property, three is that the automatic switchover performance needing two kinds of power supplys to be got well, to ensure each card signal Do not run off.Four is for ordinary electrical home appliance, and some important performances can make up with the behavior of employment, such as thundery sky, and can be artificial Pull out power supply, and a lot of equipment can not make up by artificial mode, such as the product of class of ensuring public security, pulls out power supply and just makes " security personnel " to become For blank, as being used in the equipment of signal transmission system, pull out power supply and can cause the unimpeded of system signal.What is more, sometimes people Also can not arbitrarily go to power-off source before equipment, pull out power supply.Details success, and the uncertain genus of the problems referred to above is thin Joint.This utility model is the regulated power supply that a kind of performance is the most excellent, and he has all excellent properties of current product, but also There is serial bright spot, therefore can be widely used for the needs of various electronic, the development that the adaptation electronic product moon new day is different Need.Concrete condition is as follows:

1, accumulator floating charge can remain to optimum state, because float charge voltage floating charge and load circuit are independent each other.In addition Use pulse charge form, accumulator is had significant maintenance effects, some critics claim that accumulator is filled bad on the net, and not Damage, and this measure can close the relative maximum scientific maintenance that charges of accumulator, and use such pulse charging manner, no It is only capable of the capacity making battery will not reduce with the life-span, even makes defective cell can obtain a certain degree of recovery, so meaning is The biggest.

2, Alternating Current Power Supply unit is separate with accumulator, is independent of each other, thus further increases reliability, and two is to work as In time without civil power, automatically switches, and accumulator automatically engages immediately, and when there being civil power, accumulator is excised automatically.Switch speed is fast, because of can Control silicon has strong positive feedback, thus switch performance is good, load will not be produced impact.Ensure that the performance of load.

3, overvoltage protection effect is especially good.Because defining multi-stage protection, one is in switch lightning protection unit, lightning protection stabilivolt Having the selectivity of multiple voltage stabilizing voltage, can be adjusted flexibly, this is the most necessary to the electronic circuit of some low-voltages, because typically The pressure voltage of anti-thunder tube be all upper hectovolt, for Low-voltage Electronic circuit, the most inadvisable, and the voltage stabilizing voltage of stabilivolt Select very well, can be within the scope of the lowest.Two is that relay response is rapid, quickly can respond thunderbolt, so this The switch lightning protection level that utility model selective relay and stabilivolt collectively constitute forms lightning protection.Three be Alternating Current Power Supply unit with Audion in DC power supply unit is all high back-pressure large power triode, so the back-pressure ability that can bear is strong, four is exchange The base stage of two voltage stabilizing audions has secondary pressure during overvoltage, thereby ensure that stablizing of base stage.

4, there is stream display, easy to use.When stream occurred in an Alternating Current Power Supply unit, a kind of color occurs, when separately One Alternating Current Power Supply unit occurred occurring during stream that another kind of color, its two unit the third color occur when crossing stream simultaneously, Therefore this is very convenient with use to safeguarding.

5, having broader adaptation ability than traditional regulated power supply, occurring, unexpected voltage is high, will not damage.And at voltage Lower ground side also can normally work with the period.

6, two-stage output voltage (floating charge output voltage, with load output voltage) adjustability is strong, can extensively adapt to load Need.

7, simple in circuits, easily produces and debugging, and the debug point that reason one is because in circuit is few.Two are, the most easily quantify.Adjust Examination scope is loose, workable.

8, cheap, wide adaptability, matching is strong.
