Problems solved by technology

However, the switchgear is often installed together with various electrical equipment, and the temperature of the electrical equipment is high when it is working, so that the switchgear has been working in a high temperature environment, shortening the service life of the switchgear
[0003] In order to reduce the occupation of space, most of the switch cabinets will be installed on the wall higher than the ground, which can also reduce some people who do not understand electricity to touch and prevent safety accidents, but this installation also has disadvantages; when the switch When a fire occurs due to a short circuit in the cabinet, the fire caused by the short circuit cannot be extinguished quickly and effectively, resulting in damage to the electrical appliances in the switchgear, resulting in property loss and potential safety hazards such as fire.

Abstract

The invention relates to a switch cabinet comprehensive online monitoring system. The switch cabinet comprehensive online monitoring system comprises a cabinet body, a cabinet door, a comprehensive online monitoring device, a moving contact and a fixed contact. The cabinet door is hinged with the cabinet body through hinges and is capable of rotating around the hinged part so as to close of open the cabinet body. Heat dissipation holes are uniformly formed in the upper part of the cabinet body. The comprehensive online monitoring device is installed in the cabinet body. The moving contact and the fixed contact are installed in the cabinet body. A voltage sensor, a current sensor and a temperature sensor are installed in the comprehensive online monitoring device. The cabinet body and the cabinet door are respectively made of an insulating panel. The insulating panel comprises a metal wire net layer, a high-strength fiber layer and an engineering plastic layer form inside to outside in sequence. The switch cabinet comprehensive online monitoring system is capable of monitoring the voltage, current and temperature conditions in the switch cabinet in real time, the abnormal conditions of the voltage, current and temperature in the switch cabinet can be discovered in time, operators can conveniently take measures in time, and the fire caused by a short circuit or the abnormalities of the device voltage and current in switch cabinet can be effectively prevented.

Description

technical field [0001] The invention relates to a comprehensive on-line monitoring system for a switch cabinet, which belongs to the technical field of power supply and distribution equipment. Background technique [0002] The switch cabinet is a kind of power distribution equipment. The outside line first enters the main control switch in the switch 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. However, the switchgear is often installed together with various electrical equipment, and the temperature of the electrical equipment is high during operation, so that the switchgear always works in a high temperature environment, shortening the service life of the switchgear. [0003] In order to reduce the o...
