Abstract
The utility model relates to an emergency lighting control device which is used for controlling an emergency light to work after a DC (direct current) power supply source is switched on. The emergency lighting control device comprises an AC (alternating current) monitoring unit and a DC control unit, wherein the DC contactor of the DC control unit is connected on the DC power supply source through contacts; the AC monitoring unit comprises relay circuits connected on three phase lines respectively, and at least two of the three groups of normally-open contact series connection combinations of the three-phase relays are connected in parallel and then connected in series with an AC contactor between one phase wire and the zero wire, to form a monitoring circuit; and the DC control unit is a working circuit on the DC power supply source and is formed by connecting the parallel-connected normally-close contacts of the three-phase relays in series with the contacts of the AC contactor and the DC contactor. The technical scheme achieves the purpose of switching on or off the emergency lighting without labor resources, is superior in operating reliability and real-time switching ability, and has the advantages of simple structure, low cost and low electricity consumption.
Description
Technical field
The utility model relates to the emergency lighting facility in power plant or the transformer station.
Background technology
It is very necessary that emergency lighting lamp device is set in some important events, particularly the such zone of power plant or transformer station.Must guarantee to play illuminating effect reliably when accident occurs with device as emergency lighting, the accident of avoiding being difficult to envision takes place, and mainly is the expansion of power plant or transformer station's field accident or staff's injures and deaths.The subject matter that existing emergency lighting device exists is: in order to obtain emergency lighting all the time when accident occurs, the operational mode and the structural design of the work of whole day illumination input on art designs, have been adopted, also a large amount of consumed power when extremely consuming the illuminating lamp life-span, the work light that loses illumination capability if those decrease always can not get timely replacing, just has great potential safety hazard.Between interlocking at daytime, night, regularly drop into emergency lighting if take, though can save a large amount of electric power, but regularly the automatic control circuit that drops into must cause cost to strengthen, and drop into so that artificial timing is touring, just be difficult to avoid forgetting to throw or leak the safety problem that throwing brings, also need selected parts quarterly to select the walk time input, strengthened workload.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of emergency lighting control device that starts the emergency lighting device when accident occurs automatically.The emergency lighting control device technical scheme that the utility model provides, its major technique content is: a kind of emergency lighting control device, comprise the interchange monitoring unit and the DC control unit of control emergency lighting lamp work loop dc power supply incision work, the D.C. contactor contact of DC control unit is connected on the dc power supply; Exchange monitoring unit and comprise the relay circuit that is connected on the triple line, be connected between a phase line and zero line the formation monitoring loop by choosing at least in three groups of the three phase relaies normally opened contact arranged in series combinations in twos after two groups of parallel connections connect to be provided with A.C. contactor; The DC control unit is the work of one on dc power supply loop, and being connected with ac contactor contact and D.C. contactor by the three phase relay normally-closed contacts that are connected in parallel constitutes.
The emergency lighting control device technical scheme that the utility model provides, its emergency lighting lamp is only under power plant or transformer station's AC power all loses or operating illumination all loses the situation automatically on the incision dc power supply, the work of input emergency lighting, after accident is eliminated and is recovered operate as normal, by the dc power supply of D.C. contactor contact automatic disconnection emergency lighting lamp, and enter stand-by state automatically.The technical program has realized that the work of input emergency lighting lamp appears promptly starting automatically in accident, accident is eliminated the technical purpose that back accident illuminating lamp changes standby operating state automatically over to, so not only can save a large amount of electric energy, and have and need not manpower and can finish the automatic operational capacity that drops into emergency lighting or disconnection, its functional reliability and real-time transfer capability are strong, and have that structure construction is simple, low-cost, the technical characterstic of low power consumption, the accident illuminating lamp is devoted oneself to work when accident occurs, and provides illumination to ensure in time fixing a breakdown.
Description of drawings
Accompanying drawing is the electrical schematic diagram of this accident illumination control apparatus.
Embodiment
The emergency lighting control device that the utility model separates, one is implemented to constitute as shown in drawings, its some emergency lighting lamps are connected in parallel on the dc power supply, constituted accident illuminating lamp work loop, whether this accident illumination control apparatus cuts the control device that connects on the dc power supply for control emergency lighting lamp work loop, it comprises interchange monitoring unit and DC control unit, wherein the D.C. contactor contact K1C of DC control unit is connected on the dc power supply as emergency lighting lamp input or break and the controlled switch of dc power supply.Exchange monitoring unit and comprise the relay circuit that is connected on the triple line, connect with A.C. contactor 2C after two groups of KJ1 of three-phase relay J 1, J2 and J3 three groups normally opened contact arranged in series combinations in twos and KJ2 series arm and KJ2 and the parallel connection of KJ3 series arm, be connected between a phase line circuit and zero line, constitute monitoring loop; The DC control unit is the work of one on dc power supply DC loop, being connected with A.C. contactor 2C contact K2C and D.C. contactor 1C by the three phase relay normally-closed contact KJ1 ', the KJ2 ' that are connected in parallel and KJ3 ' constitutes, and another contact of D.C. contactor 1C K1C ' is series in the monitoring loop.
The control implementation procedure of this accident illumination control apparatus is: during the operate as normal of alternating current circuit, be connected to the relay J 1, J2 and the J3 excitation that exchange three-phase line, they are series at normally opened contact KJ1, KJ2 and the KJ3 closure of monitoring loop, be connected in normally-closed contact KJ1 ', KJ2 ' and the KJ3 ' disconnection of DC control unit, A.C. contactor 2C excitation in the monitoring loop, its contact K2C that is connected in the DC control unit disconnects, directly contactor 1C dead electricity and make emergency lighting lamp and dc power supply disconnection is not worked; When power plant or transformer station's AC power all loses or operating illumination all loses accident take place, three-phase relay J 1, J2 and J3 dead electricity, normally opened contact KJ1, KJ2 and KJ3 that they are series at monitoring loop disconnect, be connected in normally-closed contact KJ1 ', KJ2 ' and the KJ3 ' adhesive of DC control unit, A.C. contactor 2C dead electricity in the monitoring loop, it is connected in the controlled node K2C adhesive of DC control unit, directly contactor 1C gets electric excitation and makes the emergency lighting lamp be connected in dc power supply, the beginning illumination work.
