SF6 gas concentration monitoring system and SF6 gas concentration monitoring method

Abstract

The invention relates to an SF6 gas concentration monitoring system and an SF6 gas concentration monitoring method. The system comprises multiple data transmitters which are arranged at multiple monitored positions in a switch room of an intelligent substation and used for measuring the SF6 concentration and O2 concentration at each monitored position and the temperature and humidity inside the switch room of the intelligent substation, an alarm transmitter which is used for receiving an alarm command of a master control module, driving alarm equipment to raise the alarm and driving a ventilation device to ventilate the switch room of the intelligent substation, a display module which is used for providing an interactive interface capable of setting the system parameters, displaying the SF6 concentration and O2 concentration at each monitored position and the temperature and humidity inside the switch room of the intelligent substation and displaying the historical curve of SF6 concentration, and the master control module which is used for processing the SF6 concentration and O2 concentration at each monitored position and the temperature and humidity inside the switch room of the intelligent substation uploaded by the multiple transmitters and sending an alarm command.

Description

technical field [0001] The present invention relates to SF 6 Gas detection technical field, and more specifically, relate to a kind of SF 6 Gas concentration monitoring system and method. Background technique [0002] SF 6 Gas has been widely used in power systems because of its good insulation, arc extinguishing ability, relatively stable, non-toxic and other physical and chemical properties. SF in action 6 Gas-insulated equipment will produce a variety of toxic decomposition products due to factors such as operation and discharge. When the seal is aging or improper operation causes SF6 to leak, SF with a larger specific gravity 6 And its decomposition products will accumulate in the indoor low-rise space, causing air hypoxia and poisoning, and pose a serious threat to the safety of indoor workers. [0003] With the continuous development of substation automation technology, new intelligent electronic devices based on microprocessors have been widely used. At the sam...

Problems solved by technology

Existing Indoor SF 6 The gas concentration monitoring device is mainly for SF 6 Gas concentration, O 2 Concentration and other parameters are monitored, and when the indoor gas concentration is detected to exceed the limit, an alarm and processing will be performed. It is not yet possible to upload the gas environment data in the switch room to the smart substation monitoring system
