Centralized power supply centralized control system

Abstract

The invention relates to a centralized power supply centralized control system. The system comprises an emergency lighting controller, a first emergency lighting centralized power supply, an explosion-proof emergency lighting distribution box and a second emergency lighting centralized power supply. The emergency lighting controller is connected with the first emergency lighting centralized powersupply and the explosion-proof emergency lighting distribution box; the explosion-proof emergency lighting distribution box is connected with the second emergency lighting centralized power supply, the first emergency lighting centralized power supply comprises a first equipment main cavity shell, a power supply control box, a first junction box, a first power supply box and a first power supply module, and the first power supply module is installed in the first power supply box; and the power supply control box and the first junction box are both located below the first power supply box, anda first one-way exhaust valve is arranged at the upper end of the first power supply box. Reliable and continuous work of the system is ensured, the performance is stable, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a centralized control system with centralized power supply. Background technique [0002] At present, the centralized power supply in the market is mainly used in indoor places (such as power distribution room, fire control room, etc.), so the protection level of the configuration is low, generally below IP33 (where IP is the abbreviation of Ingress Protection, and the IP level is for the protection of foreign objects by the electrical equipment shell. Intrusion protection level, the first 3 means to prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 2.5mm from intruding and touching the internal parts of the electrical appliance; the second 3 means to prevent rain or prevent the angle with the vertical The water sprayed in the direction of less than 60 degrees invades the electrical appliances and causes damage), and ...
