Abstract

The invention relates to a voltage-withstand test device for basin-type insulators. The voltage-withstand test device comprises a tank for accommodating a basin-type insulator voltage-withstand tool and is characterized in that a fixed conductive part which extends into the tank in a suspended manner is arranged on the tank, the basin-type insulator voltage-withstand tool is provided with a movable conductive part which extends towards the fixed conductive part in a suspended manner and used for being electrically connected with the fixed conductive part, and a conductive spring which is usedfor achieving electrical connection of the fixed conductive part and the movable conductive part is arranged on one of the fixed conductive part and the movable conductive part. The voltage-withstandtest device has the advantages that the movable conductive part is electrically connected with the fixed conductive part through the conductive spring, false circuit connection is prevented through the pre-deformation of the conductive spring, and contact reliability is achieved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a basin-type insulator withstand voltage test device. Background technique [0002] The 1100kV basin insulator is the core insulator of the 1100kV GIS. In the 1100kV power supply system, the insulation reliability of the basin insulator plays a vital role. Basin insulators have dual functions of dividing air chamber and supporting conductors, so they are widely used in GIS. The performance of pot insulators directly affects the performance of GIS, so it is very necessary to carry out withstand voltage tests on pot insulators before leaving the factory. Such as figure 1 As shown, in the prior art, when conducting withstand voltage tests on pot insulators, bus bars are usually used to assemble them. Although the number of each test is increased (8), the frequency of pot insulator 3 failures in electrical performance tests also increases. It is very high, and if the electrical...
