Alternating current and direct current universal distribution board and lighting system control method

Abstract

The embodiment of the invention discloses an alternating current and direct current universal distribution board and a lighting system control method. A second-phase power supply of a three-phase alternating current power supply connected to a quadrupole alternating current circuit breaker of the distribution board is divided into two paths after passing through the four-pole alternating current circuit breaker and is respectively connected to a second busbar and a third busbar; the positive electrode of an emergency direct current power supply accessed by the quadrupole direct current circuit breaker is divided into two paths after passing through the quadrupole direct current circuit breaker and is respectively connected to the first busbar and the second busbar, and the negative electrode of the emergency direct current power supply is divided into two paths after passing through the quadrupole direct current circuit breaker and is respectively connected to the third busbar and the fourth busbar; the alternating current and direct current universal distribution board comprises a four-pole molded case circuit breaker used for electrically connecting each busbar with an external lighting distribution box and also comprises a split-phase wiring terminal strip arranged between four-pole molded case circuit breaker and the external lighting distribution box; an interlocking control module on the alternating-current circuit breaker is used for monitoring the power supply state of a three-phase alternating-current power supply and sending an interlocking signal to the interlocking control module on the direct-current circuit breaker to switch on the emergency direct-current power supply when monitoring that the three-phase alternating-current power supply loses power.

Description

technical field [0001] The invention relates to the technical field of power distribution circuit design of lighting systems, in particular to an AC and DC universal distribution board compatible with AC and DC power supply and a lighting system control method. Background technique [0002] At present, there are three power supply requirements for the lighting system of passenger ships: normal AC230V, emergency AC230V (allowed to be switched on within 45 seconds) and temporary emergency DC230V (instantaneously switched on uninterrupted power supply). Since large passenger ships generally use high-efficiency energy-saving LED lights as lighting equipment , and the power drive of LED lamps can realize the compatibility of AC and DC power supply through technical means. Therefore, emergency LED lighting on passenger ships can also be used as temporary emergency lighting. However, the traditional 3-bus emergency switchboard design cannot The same emergency power distribution boa...

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.
