Problems solved by technology

[0004] However, the above-mentioned insulating operating rods are operated manually when operating the bracket device, which is very time-consuming and laborious, and because the inner rod and the outer rod are required to cooperate with manual operation at the same time, and the rod body has a certain weight, it is difficult for the operator to operate. Control the accuracy of the operation, the operation is very inconvenient

Abstract

The invention relates to an installation and repair device for a thermal shrinkable sleeve in an electric system, in particular to a busbar bridge thermal shrinkable sleeve fixing device. The busbar bridge thermal shrinkable sleeve fixing device comprises an execution device and a long operation rod, wherein the long operation rod is connected with the execution device, and a bracket of the execution device is controlled by the long operation rod to be opened and closed. The busbar bridge thermal shrinkable sleeve fixing device is used for achieving non-power-failure retrofitting of an insulating thermal shrinkable sleeve, and compared with an existing patent, the device has the technical advantages of saving time and labor and being precise in controlling.

Description

technical field [0001] The invention relates to a device for installing and repairing a heat-shrinkable sleeve in a power system, in particular to a device for fixing a heat-shrinkable sleeve of a bus bridge. Background technique [0002] The wiring pile head of the transformer at the 10kV and 35kV side outlets is usually connected to the busbar of the switchgear with a hard busbar. On this hard busbar, a technical measure is taken to install all insulating heat shrinkable sleeves to prevent short circuit at the transformer outlet. With the operating environment and the passage of time, the insulating heat shrinkable sleeve is prone to aging and falling off, resulting in partial exposure of the hard busbar. The equipment management department usually adopts the treatment method of power failure and additional heat shrinkable sleeve. [0003] The invention patent with the publication number CN102361293A discloses a hot-shrink sleeve live repair tool for bus bridges to solve t...
