Abstract

The invention discloses a monitoring system of a power switch cabinet, comprising a temperature monitoring component, a gas monitoring component, a current monitoring component, a wireless transmitting module, a central processing unit and a remote monitoring station, wherein the monitoring system comprises a temperature monitoring component, a gas monitoring component, a current monitoring component, a wireless transmitting module, a central processing unit and a remote monitoring station. The invention has the following beneficial effects: the invention monitors whether the power switch cabinet is in a safe or normal operation state by monitoring three data of the temperature, the air pressure and the current inside the power switch cabinet; The invention monitors the situation in the power switch cabinet through various sensors in real time, can timely find the abnormality of the power switch cabinet, and sends out a warning, so that the abnormal power switch cabinet can be timely repaired, and the loss caused by the abnormality of the power switch cabinet can be avoided.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to a monitoring system for a power switch cabinet. Background technique [0002] The power switchgear is a crucial power transmission and distribution device in the power system, so it is very important to monitor the operation of the switchgear in real time and to know the operating status of the switchgear in time. Switch cabinets are often placed in high-voltage, high-current, and strong electromagnetic interference environments. Domestic switch cabinets mostly adopt closed structures with poor heat dissipation conditions, which makes it impossible to implement manual inspections and other methods, and also adds to the implementation of conventional temperature measurement methods. difficulty. Contents of the invention [0003] The purpose of the present invention is to overcome the existing technical problems and provide a power switch cabinet monitoring system. [0004] The pr...
