Abstract
The utility model discloses a night emergency lighting device of a locomotive, which can not only ensure safe and reliable electric loop of the locomotive but also meet the requirement for lighting of drivers on duty at night. The night emergency lighting device is provided with an indoor lighting lamp D connected with a battery supply E of the locomotive, a switch SB connected with the battery supply E of the locomotive, and an electronic time relay KT1 connected in series with the switch SB; a normally-opened contact KT1-1 of the electronic time relay KT1 is connected in series with an intermediate relay KT2 and then is connected with two ends of the battery supply E of the locomotive; and a normally-opened contact KT2-1 of the intermediate relay KT2 is connected in series in the loop of the indoor lighting lamp D.
Description
Technical field:
The utility model relates to a kind of locomotive servicing unit, especially a kind ofly can guarantee the safe and reliable of locomotive electric cad system loop, can satisfy the take the opportunity locomotive emergency lighting device at night of lighting requirement of driver and conductor's night value again.
Background technology:
At present, in order to prevent that locomotive equipment, lead join with battery feed all the time and cause fire and the serious feed phenomenon of battery in locomotive is stopped transport the period, domestic conventional electric power locomotive all is provided with a master switch in the storage battery power supply loop.After locomotive is stopped transport, before getting off, the driver need the operation master switch to cut off the battery feed of locomotive control circuit, guarantee that each pipeline equipment of locomotive is in absolute off-position; The battery feed master switch that closes earlier after the driver gets on the bus could guarantee the execution of every functions such as locomotive drive, illumination.Like this, take the opportunity when driver's night value, just must carry lighting apparatus, conveniently getting on the bus or to get off and the operation of closed power switch, otherwise driver's operation of can only feeling about in the dark in environment as dark as a stack of black cats exists big potential safety hazard.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, to provide a kind of and can guarantee the safe and reliable of locomotive electric cad system loop, can satisfy the take the opportunity locomotive emergency lighting device at night of lighting requirement of driver and conductor's night value again.
Technical solution of the present utility model is: a kind of locomotive emergency lighting device at night, be provided with the indoor illumination D that joins with locomotive storage batteries power supply E, be connected to switch S B and the electronic time relay KT1 that is in series with locomotive storage batteries power supply E, two ends with locomotive storage batteries power supply E after the normal opened contact KT1-1 of electronic time relay KT1 connects with auxiliary reclay KT2 join, and the normal opened contact KT2-1 of auxiliary reclay KT2 is connected in the loop of indoor illumination D.
The utility model is selected cab lamp and the corridor lamp that possesses the dual input power supply that is isolated from each other for use, and an emergency light control button is set on each car door next door, when the driver gets on or off the bus in the condition of cutting off locomotive control circuit battery feed following night, only need press the emergency light control button reaches certain hour, emergency light can continue illumination in the car in a period of time that sets, when making things convenient for the driver and conductor to get on or off the bus and finish relevant preparation, can guarantee the safe and reliable of locomotive electric cad system loop, can satisfy driver and conductor's night value lighting requirement of taking the opportunity again, the driver and conductor does not need to carry lighting apparatus, very convenient, overcome the potential safety hazard that the driver feels about in the dark and operates and exist.
Description of drawings:
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: a kind of locomotive emergency lighting device at night, be provided with the indoor illumination D (cab lamp and the corridor lamp D1 that join with locomotive storage batteries power supply E, D2, D3, D4, D5, D6 ...), locomotive storage batteries power supply E is by air switch QA and a plurality of press button SB1 that is arranged on each car door next door and is in parallel, SB2, SB3, SB4 ... join, the press button SB1 that is in parallel, SB2, SB3, SB4 and electronic time relay KT1 are in series, two ends with locomotive storage batteries power supply E after the normal opened contact KT1-1 of electronic time relay KT1 connects with auxiliary reclay KT2 join, and the normal opened contact KT2-1 of auxiliary reclay KT2 is connected in the loop of indoor illumination D.Electronic time relay KT1 is the relay with delay feature, and can set as required its time delay.
Operation principle:
After the total power switch disconnection of driver with the dc load power loop of locomotive normal power supply, because button SB1/SB2/SB3/SB4 is an off-state, electronic time relay KT1 coil losing electricity, its normal opened contact KT1-1 disconnects, auxiliary reclay KT2 coil losing electricity, its normal opened contact KT2-1 disconnects, cab lamp and corridor lamp D1, D2, D3, D4, D5, D6 ... must not the electricity and extinguish; When needs throw light on, press the button among the SB1/SB2/SB3/SB4 any when reaching certain hour (50ms), the coil of electronic time relay KT1 gets, normal opened contact KT1-1 closure, auxiliary reclay KT2 coil gets, its normal opened contact KT2-1 closure, cab lamp and corridor lamp D1, D2, D3, D4, D5, D6 ... get electric and bright.Because electronic time relay KT1 has delay feature, so dead electricity just after being delayed to setting-up time (as 10 minutes), its normal opened contact KT1-1 just disconnects thereupon, auxiliary reclay KT2 coil losing electricity, its normal opened contact KT2-1 disconnects, cab lamp and corridor lamp D1, D2, D3, D4, D5, D6 ... must not the electricity and extinguish.
