Abstract: Aiming at the problem that the traditional test method of arrester takes a long time, this paper developed a lightning arrester test set device. The wiring auxiliary device can effectively ensure the distance between the test line and the metal structure, making the wiring more accurate, and the alarm can provide safety assistance to prevent accidental touching of energized equipment, solving the difficult technical problem of easy discharge to the structure when the arrester testis hooked up. The special bracket is applicable to the arrester dismantled from the metal structure or switchgear and can place multiple arresters on the auxiliary device, which solves the technical problem of cumbersome testing and reduced testing efficiency caused by multiple handling of testing equipment when conducting lightning arrester tests with a large number of lightning arresters. Lightning arrester test sets of devices' practical effects are remarkable.
