Abstract At present, the temperature rise problem of switchgear is very prominent. In order to reduce the temperature rise of the switchgear, the influence factors of temperature rise of high voltage switchgear are carried out by using the outlet cabinet of KYN96-12 as the research object. The simulation analysis and experimental study were carried out for the switchgear of different ambient temperature, copper bar specifications and conductor materials. The research results show that the initial ambient temperature has less influence on contact temperature rise of switchgear and the difference in temperature rise under 0℃ and 40℃ is less than 1℃. The copper bar specification and the material of circuit breaker’s contact arm have more influence on the temperature rise of the contact, the difference of temperature rise above 3℃when copper bar specification is 80mm×10mm and 120mm×10mm and above 2℃ when the contact arm’s material is aluminum and copper respectively.
