A high-voltage circuit breaker contact testing device

Abstract

The utility model relates to a kind of high-voltage circuit breaker contact test device, including base and guide pipe, the base is cylindrical, and the inner wall of its front end and rear end is respectively equipped with several front lugs and rear lugs;The front lug and rear lug are projected on the inner wall of the base, and can be moved along the radial of the base;The front end of the base is sleeved on the contact of high-voltage circuit breaker, and makes the front lug tightly abut on the outer wall of the contact;The guide pipe is cylindrical, and its front part is movably inserted in the rear end of the base, and is in close contact with the rear lug;The rear part of the guide pipe is placed outside the base, and is connected with test clamp.The utility model can effectively improve contact reliability, eliminate the contact problem and easy to loosen and other problems existing in traditional test device, and can simplify operation procedure, improve test efficiency, also can reduce the abrasion of contact, prolong service life.
