Fire-fighting emergency power supply

Abstract

The invention discloses a fire-fighting emergency power supply, which is characterized in that a shell is arranged, at least one laminate is arranged in the shell, a fire-fighting emergency power supply standard function module is respectively and fixedly arranged on the at least one laminate, at least a circuit breaker and / or switch are / is arranged on edge of the laminate where a controlled sub-function module is located or the edge of the uppermost laminate farthest or closest to bottom surface of shell, and a conductive sheet with a preset specification is electrically connected with the controlled sub-function module, and / or is connected with the connecting ends of other sub-function modules connected to the same layer of the laminate in a transmission manner. According to the invention, the use of a large number of conducting wires can be reduced, so that the overall wiring in the power supply system can be simple, the working state is stable, wires are not prone to being twisted,and the situation of electromagnetic coupling or short circuit is avoided; and the technical scheme in the embodiment of the invention has the technical effects of improving the stability and the safety of the fire-fighting emergency power supply system and reducing the production, installation and application costs.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a fire emergency power supply. Background technique [0002] Fire emergency power supply, referred to as EPS, is a backup AC power supply device that uses weak current to control strong current conversion. The fire emergency power supply can provide stable emergency power supply for fire emergency lighting fixtures and evacuation indicator lights, that is, it can be used as a backup power supply for emergency lighting fixtures after the mains power failure. [0003] According to the national standard requirements, the fire emergency power supply usually includes: step-down module, emergency power switching module, battery charge and discharge management module, charging circuit module, backup power circuit module (that is, backup power circuit), fire emergency lighting inspection control module and other sub-modules. functional module. In the traditional fire emerge...
