The invention provides a device for testing insulation of a + / -1100kV direct current wall bushing. The device comprises a metal fixing plate, a simulation wall body, a supporting frame and a base, wherein the simulation wall body is arranged at the top of the supporting frame on the base vertically, a gap is reserved at the connection position of the simulation wall body and the supporting frame, the metal fixing plate is arranged in the gap, a fixing hole is formed in the middle of the metal fixing plate, and an angle regulation device is arranged between the metal fixing plate and the simulation wall body. The device for testing insulation of the + / -1100kV direct current wall bushing can test the wall bushing in different angle states, and is simple in structure, convenient and safe to assemble and disassemble and easy to maintain.
Description
technical field [0001] The invention relates to an insulation test device, in particular to a ±1100kV DC wall bushing insulation test device. Background technique [0002] The DC wall bushing is used as the connection equipment between the DC field of the converter station and the equipment in the valve hall. The single unit carries the full voltage and full current of its pole. It is the key equipment in the DC transmission project, and its performance is related to the pole's Operational stability plays an extremely important role in DC transmission systems. [0003] The insulation property of DC wall bushing is one of the key issues affecting its safe operation. Therefore, conducting a full set of insulation characteristic tests on DC wall bushings is a prerequisite to ensure their safe and reliable operation. According to the national standard, the insulation test of the DC wall bushing is affected by the grounding wall surface and the installation angle, and the insta...
