A high-low voltage switch cabinet with heat dissipation and dust prevention

Abstract

The invention discloses a high-low voltage switch cabinet with heat dissipation and dust prevention, which relates to the technical field of the switch cabinet. The invention comprises a cabinet bodyand a heat conducting plate, A surface of that cabinet body is movably connected with the heat conduction plate, A lateral surface of that cabinet body is fixedly connected with a ventilation pipe, Anelectric fan is fixedly connected with the inside of the cabinet, An air outlet of that electric fan is connected with an air pipe, At one end of that trachea penetrate the cabinet body and extends into the interior of the ventilation pipe, both sides of the inner wall of the cabinet are provided with air exchange openings, A surface of that air change port is communicated with the ventilation pipe, A plurality of air inlets are arranged on the peripheral side of the ventilation pipe, the air inlet is located on one side of the air changer, A temperature sensor is fix on an inner wall of thatcabinet body, A dust sensor and a radio frequency signal processing device, A switch trip triggered by that monitor background to the first-level signal and the switch tripping triggered directly bythe opening contact of each sensor in the cabinet ensure that the switch circuit is cut off in time when a serious accident occurs, Convenient for no one to stick to the coal mine underground substation switchgear working state control, less production losses, with high security advantages.

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;
