Problems solved by technology

[0002] Power distribution cabinets refer to power distribution cabinets, lighting distribution cabinets, metering cabinets and other final-level equipment of power distribution systems. There are expensive electrical system components in the cabinet, so the fire protection of the distribution cabinet must be considered. The fire may occur from inside the distribution cabinet or outside the distribution cabinet. If the fire cannot be controlled in time when a fire occurs, it will be cause large economic losses to the company

Abstract

The invention provides an intelligent safety power distribution cabinet which comprises protective covers, servo motors, a first sealing strip and the like and is characterized in that each protective cover is of a shape of one quarter of a spherical shell; two protective covers are symmetrically mounted on output shafts of the servo motors by rotating shafts; two servo motors are provided and are symmetrically mounted at the upper part of a cabinet body housing; and the first sealing strip is mounted at the edge of the protective cover at the left side. According to the intelligent safety power distribution cabinet provided by the invention, by adopting a mode of combining the spherical shell type protective covers with a spray pipe, in the case of a fire outside, two protective covers can be rapidly closed and an electromagnetic water valve is opened to enable high-pressure water to be sprayed out of water spray holes so as to directly cool the protective covers and prevent heat from being transferred into the power distribution cabinet.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a power distribution cabinet. Background technique [0002] Power distribution cabinets refer to power distribution cabinets, lighting distribution cabinets, metering cabinets and other final-level equipment of power distribution systems. There are expensive electrical system components in the cabinet, so the fire protection of the distribution cabinet must be considered. The fire may occur from inside the distribution cabinet or outside the distribution cabinet. If the fire cannot be controlled in time when a fire occurs, it will be It will cause great economic loss to the enterprise. Contents of the invention [0003] In view of the above problems, the present invention provides a power distribution cabinet, which can not only prevent external fires from damaging the power distribution cabinet, but also prevent internal fires in the power distribution cabinet, and preven...
