Drawer type low voltage switch cabinet

Abstract

The invention discloses a drawer type low voltage switch cabinet, comprising a switch cabinet body, wherein the switch cabinet body is composed of an electric appliance placement area and a heat dissipation area, the surface of the electric appliance placement area is provided with a plurality of groups of drawer units, a handle is arranged on the surface of each of the plurality of groups of drawer units, an air inlet is provided one side of the heat dissipation area, the air inlet is connected to an induced draft fan through a pipe, the induced draft fan is connected to a cooler through a pipe, a shunt pipe is arranged at one end of the cooler, and an air outlet is provided at one end of the shunt pipe. When the low voltage switch cabinet provided with the heat dissipation area at one end of the switch cabinet body is running, the high temperature generated by the electronic components inside the drawer units can be reduced in time, thereby greatly prolonging the service life of thelow voltage switch cabinet; and electromagnetic shielding layers are provided inside the switch cabinet body and the drawer units, so that the electronic components inside the drawer units do not generate magnetic field interference during operation, and do not interfere with each other.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a drawer-type low-voltage switch cabinet, which belongs to the field of power system equipment. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, ope...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the poor heat dissipation effect of the existing low-voltage drawer-type switchgear, which will accelerate the aging of power components, affect the service life, and further cause problems such as fire accidents. There are too many units and the internal electrical components are different, so that the internal electrical components of the drawer unit will generate a magnetic field during operation, which will affect the adjacent drawer unit and affect its normal operation. A drawer-type low-voltage switchgear is provided
