As we all know,sulfur hexafluoride gas arc extinguishing performance is very good,so in the electrical industry,widely used.So,what are the factors that affect its arc extinguishing performance?Below,Xiaobian to say.

　　Under the action of electric arc,sulfur hexafluoride gas will decompose and dissociate,and the multi-atomic molecules will be decomposed into single atoms or charged particle gas.At about 2000℃,it will decompose into low fluoride.At about 4,000 degrees Celsius,it starts to dissociate.The internal change of gas will enhance its thermal and electrical conductivity.

　　The increase of thermal conductivity will speed up the heat dissipation rate of the arc,which is conducive to the rapid cooling of the insulating medium after the sulfur hexafluoride gas arc extinguished,so that the low fluoride compound into sulfur hexafluoride,and promote the insulation recovery,reduce the arc reignition,is conducive to arc extinguishing.

　　Because of the enhancement of high purity sulfur hexafluoride conductivity,is conducive to arc burning,under the current consistent,sulfur hexafluoride arc voltage is relatively low,arc energy is low,at this time,the arc will not break,will not occur closure phenomenon,making it difficult to reignite or reignite after arc quenching.If you have any questions,please feel free to consult.For more information,call 139-4929-0069
