Device for replacing bearing of disconnecting switch base in hot-line work

Abstract

The invention relates to a device for replacing a bearing of a disconnecting switch base in hot-line work, relates to the technical field of power grid equipment maintenance, and solves the problem that a bearing of a disconnecting switch base is not easy to replace or the replace operation is low in efficiency and high in cost. The device comprises a base extension shaft sleeve, the bearing and an extension positioning shaft, wherein the inside of the base extension shaft sleeve is use for placing the bearing; the outer diameter of the extension positioning shaft is adapted to the inner diameter of the bearing so that the extension positioning shaft can be extended into the bearing; extension shaft sleeve fixing pieces are used for fixing the base extension shaft sleeve on the disconnecting switch base; and a bearing fixing piece is used for fixing the extension positioning shaft and the bearing. According to the device, the replacement of the whole disconnecting switch base is avoided, an existing bearing seat does not need to be dismounted, the disconnecting switch base can be maintained and repaired without turning off the power, and the device is more practical for the repairand maintenance work of a large number of disconnecting switches in a power system.

Description

technical field [0001] The invention relates to the technical field of power grid equipment maintenance, in particular to a bearing replacement device for a live-operated isolating switch base. Background technique [0002] GW4 type isolating switch is a double-column horizontal rotary type, which is composed of a supporting base, an operating mechanism, a transmission mechanism, an insulating support, a conductive part, and a grounding switch. The bearing seat is an important part of the supporting base of the disconnector, which is directly related to the normal movement of the transmission part of the disconnector. Such as figure 1 As mentioned above, the bearing seat is composed of the rotating shaft 9, the shaft seat 10, the upper bearing 14, the lower bearing 15, the liner, etc. The bearing should not only ensure the flexible rotation of the isolating switch, but also ensure the stability of the fixed shaft to ensure reliable contact of the contact fingers; Porcelain...
