SF6 circuit breaker gas on-line monitor

Abstract

An SF6 circuit breaker gas detection on-line monitor relates to gas temperature, pressure and humidity detection. It uses the gas charging interface of the SF6 circuit breaker to connect with the gas exporting joint to export the gas. After the monitor is installed, the gas exporting joint automatically opens the check valve in the charging interface of the SF6 circuit breaker body. The gas enters the air cavity and passes through the temperature sensor and pressure sensor. , Humidity sensors are monitored separately and then processed by the circuit to display each parameter, and can be used for extended processing such as alarm and communication. The monitor can realize online monitoring, improve the automation of equipment maintenance, detect abnormalities in time, and avoid malignant failures.

Description

technical field

[0001] The invention belongs to the field of power systems, and relates to an SF6 circuit breaker gas on-line monitor, in particular to gas temperature, pressure and humidity detection. Background technique

[0002] Among the primary equipment of the power system, high-voltage circuit breakers are large-scale power equipment second only to generators and transformers, and the required quantity and installation investment rank ahead of the two. The health status and operation reliability of high-voltage circuit breakers are directly related to the safety and stability of the power system. Many major equipment damages, power outages and other accidents are caused by abnormal operation of high-voltage circuit breakers. With the development of social production and life, people have higher and higher requirements for the stability of power grid operation, which also prompts power production and operation units to pay more and more attention to the health of power...
