Abstract

The invention provides a 110KV total drop GIS micro-water density online monitoring system, and relates to the technical field of circuit breaker monitoring. The on-line monitoring system comprises a 126kV gas insulation closed combined electric appliance, an SF6 insulation gas leakage on-line monitoring alarm module, an SF6 micro-water density on-line monitoring module, a communication module and an instrument module. Parameters such as density, micro-water and temperature of each gas chamber are monitored in real time through the SF6 micro-water density online monitoring module, data such as GIS SF6 temperature, density and micro-water are uniformly transmitted to the SF6 monitoring data acquisition equipment main body for centralized monitoring and software analysis, and a test result and a change trend curve are given out. Monitoring data and alarm signals can be uploaded to a superior monitoring center or a remote monitoring background in real time, remote display and alarm are achieved, on-site unattended operation is achieved, whether SF6 insulating gas in a circuit breaker leaks or not can be monitored through the SF6 insulating gas leakage online monitoring alarm module, and the SF6 insulating gas leakage online monitoring alarm module is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of circuit breaker monitoring, in particular to a 110KV total drop GIS micro-water density online monitoring system. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy. Start the asynchronous motor frequently, protect the power line and the motor, and automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to the combination of a fuse switch and an overheating relay. , SF6 circuit breaker is a circuit breaker with SF6 gas as the insulating medium. [0003] At present, the existing SF6 circuit breaker cannot monitor the micro-water density of GIS online, and cannot alarm when the S...
