Problems solved by technology
The disadvantage of the connection structure of the fire-fighting linkage indicator light in the prior art is: once the common power supply end of the emergency lighting power distribution device loses power, the fire-fighting linkage indicator light of the emergency lighting power distribution device will not light up at this time. , so that the operator of the emergency lighting distribution device cannot know whether the emergency lighting distribution device is in a linkage state, which affects the correct application of the emergency lighting distribution device

The invention discloses an emergency lighting power distribution device, which comprises a common power input terminal, a standby power input terminal, at least one AC contactor, a dual power supply conversion switch and a fire-fighting linkage indicator light; the normal power input terminal and the standby power input terminal are respectively Connect at least one AC contactor and multiple miniature circuit breakers through a dual power switch to control the corresponding number of emergency lighting components; the fire linkage indicator light is connected to the normal power supply path and the backup power supply path through the main and standby interlock relays. Connect, so that when the common power supply loses power, the fire linkage indicator light is switched from the power supply path of the common power supply to the power supply path of the backup power supply, so as to ensure the normal indication of the fire linkage indicator light. The invention can ensure that the linkage state of the current emergency lighting power distribution device can be normally indicated even in the case of a power failure of the common power supply, thereby ensuring the correct application of the emergency lighting power distribution device.
Description
technical field [0001] The invention relates to the technical field of power distribution, in particular to an emergency lighting power distribution device. Background technique [0002] The emergency lighting distribution device is usually used to control the emergency lighting lamps, and has the function of controlling the controlled equipment to perform predetermined actions after receiving the fire signal. The emergency lighting power distribution device in the prior art usually adopts dual power input (i.e. common power supply and backup power input), and can switch to the backup power supply when the normal power supply cannot normally supply power to the emergency lighting components; the existing emergency lighting power distribution The device usually needs to be equipped with a fire linkage indicator light to indicate the linkage status of the emergency lighting power distribution device. At present, the power supply of the fire linkage indicator light is generally...
