Description

A kind of emergency lighting switching board

Technical field

The utility model relates to substation illumination systems technology field in electric power system, is specially a kind of emergency lighting switching board.

Background technology

Power supply enterprise's services more and more high-quality, qualified electric energy is provided to power consumer, and ensure the electricity consumption that power consumer is safe and reliable, promote the Consumer's Experience of power consumer, become the important goal of the continuous enterprise quality of power supply enterprise, and as the important step of supply of electric power, i.e. the safe and stable operation of transformer station, has a very important role wherein.

Emergency lighting is as the important component part of transformer station, it is according to Electricity Department pertinent regulations and the on-the-spot actual conditions run, ensure that on-the-spot circuit breaks down the requirement of back lighting electricity consumption, emergency lighting throws light on respectively according to diverse location, illumination be uninterruptedly the powerful guarantee of accident treatment, the normal monitoring power supply of current emergency lighting takes from accident security personnel section, and accident emergency power supply is more reliable, the little bus of emergency lighting is often with the alternating current that security personnel's section is come, send through Closing Switch, and the illumination Special disc under 380V central sections is taken from normal illumination, after normal illumination loses for some reason, emergency lighting can not drop into automatically, the P cock that must manually close on emergency lighting switching board could drop into and exchange emergency lighting, direct current emergency lighting could be dropped into after only having security personnel's section dead electricity.

Summary of the invention

The purpose of this utility model is to provide a kind of emergency lighting switching board, it is when normal illumination power supply disappears or power safety fuses, exchange emergency lighting automatically to drop into, exchange emergency lighting power supply and take from security personnel's section, power quite reliable, when also dead electricity or interchange emergency lighting power safety fuse section of ensuring public security, direct current emergency lighting drops into automatically, interchange emergency lighting is automatically cut into after exchanging emergency lighting power up, the discharge time of storage battery can be extended, normal illumination cuts off emergency lighting, automatically no matter make illumination when all uninterrupted after recovering.

The utility model technical solution problem adopts following technical scheme:

A kind of emergency lighting switching board is provided, it comprises relay YJ, relay 1YJ, relay 2YJ, relay 3YJ, closing coil JC, filter 1ZC, filter 2ZC, solenoid YA, resistance R and button and indicator light, intermediate relay ZJ, relay 1YJ, relay 2YJ, relay 3YJ connects as security personnel's section power supply A, B, C relatively, relay YJ and solenoid YA connect into emergency power supply A relatively, it is characterized in that: described emergency lighting switching board has added 3 voltage relays on original loop, i.e. relay 4YJ, relay 5YJ, relay 6YJ, the three phase mains that whole emergency lighting switching controls loop monitors illumination Special disc respectively is also accessed in 3 voltage relay one end, described relay 4YJ, relay 5YJ, the other end contact parallel connection of relay 6YJ accesses the potential winding of intermediate relay ZJ afterwards.

As preferred embodiment, the normal opened contact of described ZJ and the normally closed contact of relay YJ and after connecing and relay 1YJ, relay 2YJ, relay 3YJ 3 normal opened contact strings in the loop of closing coil JC, another of intermediate relay ZJ is to the normally closed contact of normal opened contact and relay YJ and connect rear string in the wire loop of filter 2ZC.

As preferred embodiment, the indicator light of described emergency lighting switching board is connected between the auxiliary contact of closing coil JC and filter 1ZC respectively, and instruction exchanges and drops into and direct current input respectively.

The utility model compared with prior art, its beneficial effect is: it is when normal illumination power supply disappears or power safety fuses, exchange emergency lighting automatically to drop into, exchange emergency lighting power supply and take from security personnel's section, power quite reliable, when also dead electricity or interchange emergency lighting power safety fuse section of ensuring public security, direct current emergency lighting drops into automatically, interchange emergency lighting is automatically cut into after exchanging emergency lighting power up, the discharge time of storage battery can be extended, normal illumination cuts off emergency lighting, automatically no matter make illumination when all uninterrupted after recovering.

Accompanying drawing explanation

Fig. 1 is the line principle of a kind of emergency lighting switching board of the present utility model.

Fig. 2 is 3 the voltage relay loops increased.

Embodiment

Below by specific embodiment, the utility model is specifically described.

A kind of emergency lighting switching board, it comprises relay YJ, relay 1YJ, relay 2YJ, relay 3YJ, closing coil JC, filter 1ZC, filter 2ZC, solenoid YA, resistance R and button and indicator light, intermediate relay ZJ, relay 1YJ, relay 2YJ, relay 3YJ connects as security personnel's section power supply A, B, C relatively, relay YJ and solenoid YA connect into emergency power supply A relatively, emergency lighting switching board has added 3 voltage relays on original loop, i.e. relay 4YJ, relay 5YJ, relay 6YJ, the three phase mains that whole emergency lighting switching controls loop monitors illumination Special disc respectively is also accessed in 3 voltage relay one end, relay 4YJ, relay 5YJ, the other end contact parallel connection of relay 6YJ accesses the potential winding of intermediate relay ZJ afterwards.

The normal opened contact of ZJ and the normally closed contact of relay YJ and after connecing and relay 1YJ, relay 2YJ, relay 3YJ 3 normal opened contact strings in the loop of closing coil JC, another of intermediate relay ZJ is to the normally closed contact of normal opened contact and relay YJ and connect rear string in the wire loop of filter 2ZC.
