Abstract

The invention relates to a lightning arrester testing apparatus which comprises a box body with an openable-closable upper cover.An alternating current motor is detachably arranged on the lower end face of the upper cover of the box body is arranged in the box body, a rotating shaft of the alternating current motor vertically and outwards penetrates through the upper box of the box body, a rotating platform is detachably arranged on the rotating shaft, and a group of lightning arrester placement holes are formed in the rotating platform.A detachable pressurizing insulation rod and a discharge lever are further arranged on the box body, and a pressurizing spring contact and a grounding spring contact which are matched with a lightning arrester to be tested are arranged at the upper end of the pressurizing insulation rod.A discharge spring contact matched with the lightning arrester to be tested is arranged at the upper end of the discharge lever.The grounding spring contact and a discharging spring contact are grounded.The problem that an existing lightning arrester testing apparatus is not reasonable enough and potential safety hazards exist can be solved, and the lightning arrester testing apparatus is simple in whole structure and convenient to achieve and can be widely applied to the field of lightning arrester tests.

Description

technical field [0001] The invention relates to the field of lightning arrester testing, in particular to a lightning arrester testing device, and more particularly to a 10kV lightning arrester automatic testing device. Background technique [0002] Surge arresters are commonly used devices in the electric power field. Their maintenance tasks are heavy, time-consuming, work-intensive, and have high potential safety hazards. The leakage current of the metal oxide surge arrester under DC U1mA and 0.75U1mA is a routine test item stipulated in the GB11032-2000 standard. It is mainly to check whether the valve plate is damp and aging, and to determine whether its operating performance meets the requirements. The arrester, especially the 10kV arrester, is removed from the base during the test and placed upright on a relatively flat ground to ensure sufficient safety distance and test requirements. But the tools used now are also temporary objects, such as wooden boards, tables an...
