Partial discharge gradually develops, through the continuous erosion of the insulating medium around it, eventually leading to the failure of the entire insulation system, so partial discharge is the main cause of insulation deterioration, and it is also an important sign and manifestation of insulation deterioration, closely related to the deterioration and breakdown process of insulation materials, can effectively reflect the internal insulation failure of power equipment. In particular, the e

Since the signing of the Kyoto Protocol in 1998, the Chinese government has been committed to international environmental cooperation with a responsible attitude and with the international community, and has made some achievements, but at the same time, it also faces a series of difficulties. SF6 is currently considered to have the highest greenhouse gas warming potential, and is also one of the six greenhouse gases controlled by the Kyoto Protocol, and its influence on climate cannot be ignored

Sulfur hexafluoride gas has excellent insulation and arc extinguishing properties, and is called "century gas". Its emergence has caused a very far-reaching innovation in high voltage switchgear. Because sulfur hexafluoride gas has excellent insulation and arc extinguishing performance, it is widely used in today's transmission and distribution switchgear above 110kv and 24kv~36kv generator protection circuit breakers. In the distribution switchgear above 35kv, the electrical industry department

1. According to the standard, the SF6 electrical equipment is inflated to the rated pressure, and the gas detection can be carried out after 24 hours; 2. In order to ensure the accuracy of measurement, SF6 gas around the equipment should be blown before detection, and the residual gas between the double seal should also be drained; 3. When the local dressing method is used for leak detection, the dressing cavity should adopt regular shape as far as possible, such as square, cylinder, etc., whi
