Problems solved by technology
[0004] In order to solve this problem, some projects currently use LED lamps containing batteries as emergency lighting and temporary emergency lighting, which can reduce a set of distribution boards and corresponding power supply lines. However, the purchase price of LED lamps containing batteries will be higher than The overall purchase cost of ordinary LED lamps is not very obvious compared with traditional solutions. In addition, a large number of battery lamps will also bring a lot of maintenance costs in the later maintenance process. Comprehensive consideration is not an economical and applicable solution.

The embodiment of the present invention discloses an AC-DC universal power distribution board and a control method for a lighting system. The two circuits are respectively connected to the second busbar and the third busbar; the positive pole of the emergency DC power supply connected to the four-pole DC circuit breaker is divided into two circuits and connected to the first busbar and the second busbar respectively after passing through the four-pole DC circuit breaker. Busbar, the negative pole of the emergency DC power supply is divided into two circuits by the four-pole DC circuit breaker and connected to the third busbar and the fourth busbar respectively; the four-pole plastic case that electrically connects each busbar to the external lighting distribution box Circuit breaker; the split-phase terminal block between the four-pole molded case circuit breaker and the external lighting distribution box, the interlock control module on the AC circuit breaker is used to monitor the power supply status of the three-phase AC power supply, and when the monitoring When the three-phase AC power supply loses power, it sends a chain signal to the interlock control module on the DC circuit breaker to turn on the emergency DC power supply.
Description
technical field [0001] The invention relates to the technical field of power distribution circuit design of a lighting system, in particular to an AC-DC universal power distribution board compatible with AC and DC power supply and a lighting system control method. Background technique [0002] At present, the lighting system of passenger ships has three power supply requirements: normal AC230V, emergency AC230V (allowed to be connected within 45 seconds) and temporary emergency DC230V (instantly connected to uninterrupted power supply). Because large passenger ships generally use high-efficiency energy-saving LED lights as lighting equipment , and the power drive of LED lights can realize the compatibility of AC and DC power supply through technical means. Therefore, emergency LED lighting on passenger ships can usually also be used as temporary emergency lighting. However, the traditional 3-busbar emergency switchboard design cannot The same emergency switchboard can provid...
