Abstract

The invention discloses an isolating switch base with a ball bowl surface bearing, and an installation method thereof. The isolating switch base comprises: a tool arm turntable provided with a connecting base, a cylindrical main shaft and a screw rod; an insulator rotating base arranged on the cylindrical main shaft; a first ball bowl surface bearing positioned on the outer side of the insulator rotating base; a second ball bowl surface bearing positioned on the outer side of the insulator rotating base; a cap screw arranged on the outer side of the first ball bowl surface bearing; and a rain cover arranged on the outer side of the second ball bowl surface bearing. The rotating mode of spherical bowl surface contact is adopted for increasing the contact surface, transverse and longitudinal bearing pressure can be met, oxidation is not prone to occurring, and later maintenance and repair of operation and maintenance personnel are facilitated; and the problems of maintenance incapability, operation jamming and the like caused by the existing transmission mode of the disconnecting switch are solved, the equipment operation reliability is improved, the equipment failure rate is reduced, and the isolating switch base has important significance in improving the operation and maintenance working efficiency of a transformer substation, the equipment operation reliability and the like.

Description

technical field [0001] The invention relates to the field of isolating switch accessories, in particular to a base of an isolating switch with a spherical bowl surface bearing and an installation method. Background technique [0002] Isolating switch is a switching device without arc extinguishing function that has the functions of isolating power supply, switching operation, and connecting and cutting off small current circuits. The isolating switch is mainly used to reliably isolate the part that needs to be powered off from the live part in the high-voltage power distribution device to ensure the safety of maintenance work. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. High-voltage isolating switch, that is, an isolating switch with a rated voltage above 1kV. Its working principle and structure are relatively simple...
