Abstract
The utility model discloses a miniaturized hydropower station accident emergency illumination system. The system comprises a generator three-phase power supply and also an AC/DC transformer. The network access output end of the generator three-phase power supply is connected with a coil 1KM through a normally-closed contact; the motion switch 1K of the coil 1KM is a conduction switch of the AC/DC transformer; and the output end of the AC/DC transformer is connected an illumination load circuit. According to the utility model, a single-phase AC power supply is inputted into the AC/DC transformer for changing into a stable DC power supply and then is transmitted to the illumination load circuit for supply illumination in case of an accident condition. Compared to the prior art, no storage batteries or similar electricity storage devices are adopted, on the contrary, the three-phase generator of a hydropower station is relied on as a power supply so that the use cost for accident illumination is substantially reduced and the safety and reliability are quite high.
Description
Technical field
The utility model relates to a kind of power lighting system, specifically refers to small hydropower station accident emergency illuminator.
Background technology
Along with social development, electric equipment is more and more, and power load increases the weight of day by day, and comparatively speaking the possibility of breaking out of fire increases, and automatic fire alarm system, carries out fire forecast, just in case breaking out of fire should have perfect fire simultaneously
accidentilluminator and broadcast persuasion system, the relevant fire-fighting equipment fire extinguishing of Evacuation startup in time, reduces casualties, reduces property loss.Current accident lighting system has been widely used in existing building, the public arena such as hospital, school, cinema, public place of entertainment particularly, also has the part using emergency lighting as architectural design of modern civil buildings, house, normal illumination and emergency lighting are all to use 220V power supply, they are all to adopt alternating current at ordinary times, but when there is the interruption of electric accident Alternating Current Power Supply, the actuating of relay of emergency lighting circuit, automatically changes the direct-current power supply by 220V emergency lighting power supply.The lamp holder of all genus emergency lightings, general " ☆ " mark that useful red paint is put on its lampshade, to distinguish with normal illumination, general Lu control room, boiler aisle and stairs port are all equipped with emergency lighting.Hydroelectric station, as the end of electric power system, is often positioned at field, particularly small hydropower station, generally all be in remote mountain area, end in circuit, is not adopt common emergency lighting during emergency stop valve trip, but adopts the release of storage of electrical energy to keep illumination to move.Therefore, the high electric energy storage device of cost is the essential items of hydroelectric station, particularly small hydropower station, and its useful life is limited, is generally about 2 years and just needs to change, and has greatly improved use cost.
Utility model content
The purpose of this utility model is to provide small hydropower station accident emergency illuminator, solves current hydroelectric station emergency lighting dependence electric energy storage device, problem with high costs, reaches the object of safe handling.
The purpose of this utility model is achieved through the following technical solutions:
Small hydropower station accident emergency illuminator, comprise generator three phase mains, also comprise alternating current-direct current transformer, the networking output of generator three phase mains is connected with coil 1KM by normally closed electric shock, the step switch 1K of coil 1KM is the actuating switch of alternating current-direct current transformer, and the output of alternating current-direct current transformer connects lighting load circuit.The utility model is no longer dependent on storage battery, but rely on the generator in hydroelectric station that power lighting is provided, in the accident in hydroelectric station, the probability that generating set does not rotate is in the extreme little, and, never found that three of threephase generator did not work when identical, in the statistics of existing accident, nearly all belong to circuit part fault, and threephase generator is still in normal operation, therefore, the utility model be take the power supply that the power supply of threephase generator in hydroelectric station is electric power system, using one in generator three phase mains as power supply and through alternating current-direct current transformer, become direct current, on generator three phase mains, be connected with a coil 1KM, connection line is through the normally-closed contact of relay, when there is accident situation, normally-closed contact action, closing coil 1KM, after coil 1KM connects, its step switch 1K connects, the AC power of individual event is input to alternating current-direct current transformer, become galvanic current source, then flow to lighting load circuit, illumination when accident conditions is provided.The utility model in terms of existing technologies, does not adopt storage battery or similar electric energy storage device, depends on the threephase generator in hydroelectric station as power supply, greatly reduces the use cost of emergency lighting, and safe and reliable.
Before described lighting load circuit, be also in series with divider resistance R and indicator light L.Further, in order to improve security performance of the present utility model, ensure the normal operation of lighting load circuit, by divider resistance R and the indicator light L of connecting before lighting load circuit, divider resistance R is as main dividing potential drop original paper, can realize the control of illumination load circuit voltage adjustable, adopt rheostat as divider resistance R, can be applicable to different accident lighting systems, meet the voltage of different emergency lighting circuit, indicator light L, as the sign of divider resistance normal operation, has obvious effect, is applicable to the demonstration under working condition.
On the output of described alternating current-direct current transformer, be also connected with fuse FU.Further, in order to ensure the fail safe of lighting load circuit, the sudden change that prevents three phase electric machine produces and impacts accident lighting system, can fuse be installed at the output of alternating current-direct current transformer, when the output voltage sudden change after transformation surpasses certain limit, fuse blows, has ensured that accident lighting system is not burned.
The utility model compared with prior art, has following advantage and beneficial effect:
1 the utility model small hydropower station accident emergency illuminator, the power supply that the power supply of threephase generator in hydroelectric station of take is electric power system, using one in generator three phase mains as power supply and through alternating current-direct current transformer, become direct current, on generator three phase mains, be connected with a coil 1KM, connection line is through the normally-closed contact of relay, when there is accident situation, normally-closed contact action, closing coil 1KM, after coil 1KM connects, its step switch 1K connects, the AC power of individual event is input to alternating current-direct current transformer, become galvanic current source, then flow to lighting load circuit, illumination when accident conditions is provided, the utility model in terms of existing technologies, do not adopt storage battery or similar electric energy storage device, depend on the threephase generator in hydroelectric station as power supply, greatly reduce the use cost of emergency lighting, and safe and reliable,
2 the utility model small hydropower station accident emergency illuminators, by divider resistance R and the indicator light L of connecting before lighting load circuit, divider resistance R is as main dividing potential drop original paper, can realize the control of illumination load circuit voltage adjustable, adopt rheostat as divider resistance R, can be applicable to different accident lighting systems, meet the voltage of different emergency lighting circuit, indicator light L is as the sign of divider resistance normal operation, there is obvious effect, be applicable to the demonstration under working condition;
