Isolation switch suitable for switching bus conversion current in environment-friendly gas

The invention belongs to the technical field of power switch equipment, and particularly relates to an isolating switch suitable for switching bus conversion current in environment-friendly gas. The isolating switch suitable for switching the bus conversion current in the environment-friendly gas comprises a shell and is characterized in that a moving contact and an isolating station static contact seat are arranged in the shell, a main conductive static contact and a hollow static arc contact higher than the main conductive static contact are mounted in the isolating station static contact seat, and a spiral groove is formed in the surface of the static arc contact. The isolating switch has the beneficial effects that the electromagnetic field structure arc extinguish chamber is introduced into the isolating switch, so that the isolating switch can be switched on and off a bus conversion current of thousands of amperes, and the bus conversion voltage can reach 350V; and the service life is long. 本发明属于电力开关设备技
