A heat dissipation and dustproof high and low voltage switch cabinet

Abstract

The invention discloses a heat dissipation and dustproof high and low voltage switch cabinet, which relates to the technical field of switch cabinets. The invention includes a cabinet body and a heat conduction plate, one surface of the cabinet body is flexibly connected with the heat conduction plate, a ventilation pipe is fixedly connected to the side of the cabinet body, an electric fan is fixedly connected to the inside of the cabinet body, an air pipe is connected to the air outlet of the electric fan, and one end of the air pipe runs through the cabinet The body and extend to the inside of the ventilation pipe. There are air exchange ports on both sides of the inner wall of the cabinet. One surface of the air exchange port is connected with the ventilation pipe. A temperature sensor, a dust sensor and a radio frequency signal processing device are fixed, and the present invention triggers the tripping of the first-level signal through the monitoring background and directly triggers the tripping of the switch through the opening contacts of the sensors in the cabinet to ensure that the switch circuit is cut off in time in case of a serious accident. It is convenient for unattended coal mine underground substations to control the working state of the switchgear, less production loss, and has the advantages of high safety.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, in particular to a high and low voltage switch cabinet for heat dissipation and dust prevention. 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 control, motor magnetic switches, various AC contactors, etc. 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. There are many classification methods of switchgear, such as the installation method of circuit breaker, it can be divided into mobile switchgear and fixed switchgear; Armored switchgear, etc. [0003] The switchgear generates a lot of heat d...

Problems solved by technology

[0006] The purpose of the present invention is to provide a heat dissipation and dustproof high and low voltage switchgear, which is used in unattended coal mine underground substations, through the design of ventilation pipes, inclined wind guide plates, inclined wind deflectors and heat conduction plates, to solve the problem of The dust and insects from the outside enter the switch cabinet through the cooling fan and affect the normal operation of the switch cabinet. Through the monitoring background, the first-level signal triggers the switch trip and directly triggers the switch trip through the output contacts of the sensors in the cabinet. Cut off the switch line in time in case of an accident;
