Research on the Application Mode and Operation Monitoring of Tank-type Circuit Breaker Heating Tapes in 500kV Substations in High-Cold Areas

Four Fast At present, most low - voltage switchgear assemblies in China mainly use SF₆ gas at a pressure of 0.5 - 0.6 MPa as the insulating medium. However, when the ambient temperature drops to around - 32.5°C, the SF₆ gas will quickly liquefy, resulting in serious problems with the insulation and interrupting capabilities of the product. To avoid affecting the operation of low - voltage switchgear assemblies in alpine regions, tracing heaters are often used to prevent the liquefaction of SF₆ gas
