Abstract

The invention discloses a combination device for testing large current aging and vacuum degree of a vacuum arc extinguish chamber. An aging switch of an aging bench (1) is connected with a conversion cylinder (6); a pneumatic switch of the aging bench (1) is connected with a clamping cylinder (4) and a pull-down cylinder (5); a pair of conductive blocks A and B and another pair of conductive blocks C and D are arranged on the conversion cylinder (6); the conductive A is connected with an aging clip line (7); the conductive B is connected to the aging bench (1) through an aging line (8); the conductive C is connected with the aging clip line (7); the conductive D is connected to a vacuum gauge (2) through a high-voltage line (9); and the vacuum gauge (2) is connected with a contact Ja-1, acontact Ja-2 and a contact Ja-4 of an alternating current contactor Ja respectively. In the invention, test functions of large current aging and vacuum degree are combined, so the conductive blocks at a static end are prevented from being collided in an original test process, the labor intensity of an operator is reduced, the working time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a vacuum interrupter, in particular to a combined device for high-current aging and vacuum degree testing of the vacuum interrupter, which belongs to the technical field of electric appliances. Background technique [0002] Vacuum extinguishing chamber aging is to use DC low voltage and high current to arc and ablate the contact surface of the sealed arc extinguishing chamber to improve the withstand voltage and breaking capacity of the arc extinguishing chamber. The vacuum degree measuring instrument of vacuum interrupter is developed according to the principle of magnetron vacuum gauge, and its characteristic is to generate high voltage and receive tiny current. At present, the high-current burn-in and vacuum test of the vacuum interrupter need to be carried out on the burn-in bench and the test bench respectively, which not only requires long operation time, low production efficiency, but also high labor intensity for operat...
