There are many ways to detect SF6 gas leaks. Because sulfur hexafluoride is a negative electric gas, it has the characteristic of absorbing free electrons to form negative ions, and the methods of leak detection are mostly made use of this characteristic. There are four commonly used sulfur hexafluoride gas leakage detection methods: ultraviolet ionization detection, electron capture detection, vacuum high frequency ionization detection and negative corona discharge detection.

In the last hundred years, the earth's climate is undergoing a significant change with global warming as the main feature. This global warming is caused by both natural climate fluctuations and the greenhouse effect, which is enhanced by human activities. Reducing greenhouse gas emissions and mitigating climate change are the main objectives of the United Nations Convention on Climate Change and the Jingdong Agreement. Therefore, our country is facing more and more international pressure to redu

A substation is a power facility that changes voltage, receives and distributes electrical energy in a power system. In the operation of substation, more than 95% of the information obtained by the traditional operation inspection comes from visual observation. The "four-remote" currently used in substations can only achieve video surveillance in substations, and cannot analyze the operating status of target equipment, which leaves hidden dangers for the safe operation of substations.
