Description

Relay-type lightning protection quick-break power supply
Technical field
Belong to electronic technology field.
Background technology
Source of stable pressure is the ingredient that electronic product is important, and the quality of power supply directly affects the performance of entirety, electronic product Make rapid progress, need the function of power supply also to tend to reach perfection and could meet the requirement of product, so having the most outstanding steady at present Voltage source.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.Such as this enterprise once Apply for multiple product about security personnel's equipment.The product of these equipment is the highest to the requirement of power supply, and overcritical degree will be the highest In ordinary electrical home appliance, although having a lot of regulated power supply on the market, but the most all can not meet the demand of this series products, its reason is such as Under:
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.
Just because of above-mentioned factor so that the development of power supply receives obstruction, the performance of electronic product to be made obtains more The most perfect, it is necessary first to be exactly the innovation of power supply, so needing brand-new thinking to carry out perfect to power supply.
Summary of the invention
In order to solve overvoltage, the flimsy problem of active part, the contradiction that the charge and discharge voltage of accumulator does not waits, this reality Propose a kind of new measure with novel, use the rapid relay of response as fast tripping protection during thunderbolt overvoltage, use height Back-pressure large power triode, carries out direct current and the automatic switchover exchanged, defines direct current and exchange two loops, the most not in this measure Interference, debugging property is strong, so that this power supply has extensive and special purposes.

2, voltage stabilizing audion is NPN audion, and its back-pressure value is >=300V.
3, floating charge audion is PNP triode.
It is further described below:
One, the AC voltage-stabilizing unit of the present invention be designed with 3 measures, therefore have the strongest fan-out capability, meet exchange steady Pressure unit, the double heavy duty needs of accumulator, highly reliable.
Due to the AC voltage-stabilizing unit in the present invention, it is the main time to loaded work piece, uses the form penetrated with output, Expanding the output of audion, load capacity is very strong, is in " big horse " and draws the state of " dolly ".Thus it is steady to improve exchange The reliable life of pressure unit, two is the current limliting having voltage stabilizing audion, thus voltage stabilizing audion is formed protection, so reliability Height, three is that the voltage stabilizing to base stage has special design.
Two, the present invention has the explanation of the strongest overvoltage protection ability.
Relay quick-break lightning protection unit by lightning protection relay (in Fig. 1 2), lightning protection stabilivolt (in Fig. 1 2.0), Two isolating diodes (2.1 in Fig. 1 and 2.2) form:
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 diode of backup voltage stabilizing branch road (in Fig. 1 5.6) Number is more than the diode number of work voltage stabilizing branch road (in Fig. 1 5.5), and therefore, required breakdown voltage is than work voltage stabilizing The breakdown voltage of branch road is high, thus under normal conditions, and backup voltage stabilizing branch road is worked voltage stabilizing branch road clamper, is in currentless rest State, when overvoltage, and when having exceeded the voltage of work voltage stabilizing branch road, backup voltage stabilizing branch road starts, voltage stabilizing again, thus ensures The stablizing of voltage stabilizing transistor base voltage, substantially increases reliability.
2, the reason that overvoltage protection ability is strong: when there is thunderbolt and shoving because one be voltage stabilizing audion be high inverse-voltage tube So being difficult to infringement, two is when the voltage stabilizing branch voltage that works exceeds the voltage stabilizing value of backup voltage stabilizing branch road, and backup voltage stabilizing branch road is led Logical, become two-way and shove logical, the base stage of voltage stabilizing audion is formed secondary pressure, thus ensure that the output electricity of overall channel level Pressure.
The effect of the semifixed resistor in shared voltage stabilizing branch road is that voltage stabilizing value is formed accurate adjustment, and the diode connected is shown as Coarse adjustment.
Four, AC voltage-stabilizing 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, voltage stabilizing three pole The pressure drop of the overcurrent protection resistance that pipe emitter stage is connected increases, when exceeding the threshold value of current limliting instruction, and the base of voltage stabilizing audion Flow point stream, thus cause emitter current to reduce.
Five, there is wider mains input voltage explanation.
1, the scope that civil power is wider can be operated in.
Being high-power high countervoltage triode in circuit, back-pressure value >=300 volt of its colelctor electrode, so rectifier transformer is secondary The voltage of end 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 AC voltage-stabilizing cell level Penetrate and damage with pipe.So the present invention can be operated in electric hypodynamic place, and also will not in the place that electric power is too strong Infringement.
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, DC power supply unit rectification output has electricity, through floating charge audion, then returns to the ground of bridge rectifier one through accumulator Line end, is also the negative terminal of accumulator, thus forms 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 AC voltage-stabilizing unit, and AC voltage-stabilizing unit is to load Current supply circuit is the output electric current of bridge rectifier two, through AC voltage-stabilizing unit to load, is then return to ground wire, that is to say The earth terminal of bridge rectifier two.
It is connected to stop filling in comparison inclined resistance (in Fig. 1 10.21) at the negative phase end stopping filling device (in Fig. 1 10.2) and stops filling Under Bi compare, inclined resistance is formed and stops filling the threshold voltage of device negative phase end, and its principle is, when accumulator floating charge to this threshold value, stops filling Device output high pressure, makes floating charge audion disconnect, and stops charging to accumulator, and now a streams trickle resistance provides dimension to accumulator The trickle held.
Seven, civil power and accumulator duplicate supply explanation, its power supply trend is as shown in Figure 2.
When mains sometimes, bridge rectifier two exports high pressure, after AC voltage-stabilizing unit, enter load unit Power end, conversion and control resistance by conversion and control audion trigger, therefore by the earth terminal of load unit, load current pass through The colelctor electrode of conversion and control audion, to emitter stage, because the grounded emitter line of conversion audion, has therefore been returned to ground wire, It it is i.e. the earth terminal of bridge rectifier two.
When mains without time, bridge rectifier two without output, AC voltage-stabilizing unit without output, but now accumulator to Load unit is powered, and electric current is after load unit, through switching audion (in Fig. 2 13.1) connecing to bridge rectifier one Ground end, is i.e. the negative terminal of accumulator, completes power supply.
Eight, the principle explanation of direct current switch unit.
When mains sometimes, bridge rectifier two exports high pressure, and conversion and control audion (in Fig. 1 12.2) is touched Sending out, produce base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is, bridge Formula rectification circuit two positive pole, through control unit transistor base to ground, collector current loop is, AC voltage-stabilizing unit defeated Go out the colelctor electrode through load unit entrance conversion and control audion and then arrive ground.Now switching audion is without trigger voltage, also It is i.e. no Anode current, for off-state.
When without mains, bridge rectifier two, does not produces without electricity without output, conversion and control resistance (in figure 12.1) Base flow, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the voltage of accumulator is through overload After unit, handover trigger resistance (in Fig. 1 13.2) triggering switching audion (in Fig. 1 13.1), loop now is, stores The anode of battery enters load unit through DC-isolation diode (in Fig. 1 9.1), then enters switching after load unit The colelctor electrode of audion, is entered the earth terminal of bridge rectifier one, that is to say accumulator by the emitter stage of switching audion Negative pole.
The present invention 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.The present invention 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 has Series bright spot, therefore can be widely used for the needs of various electronic, the development need that the adaptation electronic product moon new day is different. 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.
2, AC voltage-stabilizing 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 Protected effect is especially good.Because defining multi-stage protection, one is in switch lightning protection unit, and lightning protection stabilivolt has multiple voltage stabilizing volt The selectivity of number, can be adjusted flexibly, and this is the most necessary to the electronic circuit of some low-voltages, because the pressure volt of general anti-thunder tube Number is all upper hectovolt, for Low-voltage Electronic circuit, the most inadvisable, and the voltage stabilizing voltage of stabilivolt selects very well, permissible Within the scope of the lowest.Two is that relay response is rapid, quickly can respond thunderbolt, so this utility model selects to continue The switch lightning protection level that electrical equipment and stabilivolt collectively constitute forms lightning protection.Three is in Alternating Current Power Supply unit and DC power supply unit Audion be all high back-pressure large power triode, so the back-pressure ability that can bear is strong, four is exchange two voltage stabilizing audions Base stage has secondary pressure during overvoltage, thereby ensure that the stablizing of base stage.
4, there is stream display, easy to use.When stream occurred in an AC voltage-stabilizing unit, a kind of color occurs, when separately One AC voltage-stabilizing 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.
