Static contact socket of sulfur hexafluoride circuit breaker

The invention relates to the technical field of electrical equipment, in particular to a static contact socket of a sulfur hexafluoride circuit breaker. The static contact socket is provided with a conical support part, the conical support part is connected with a protecting sleeve, a hole matched with a static arc contact is arranged at the conical support part, a shielding cover is fixedly connected to the static contact socket and provided with contact fingers, and a cylindrical surface matched with the contact fingers is arranged on the static contact socket. The static contact socket hasthe characteristics that the static contact socket has high support strength for the static arc contact and also facilitates gas flowing of the static contact socket, and the cooling and circulation functions of high-temperature gas is improved. 本发明涉及电气设备技术领域，更具体地，涉及种六氟化硫断路器的静触头座，静触头座设有锥形支撑件，锥形支撑件连接有护套，锥形支撑件设有与静弧触头配合的孔，静触头座固定连接有屏蔽罩，屏蔽罩设有触指，静触头座设有与触指配合的圆柱面。本发明具有对静弧触头支撑强度高的特点，同时有力于气体流过静触头座，提高高温气体的冷却、循环的作用。
