Support of insulated drainage wire for live-line equipment maintenance operation

Abstract

The invention relates to a support of an insulated drainage wire for live equipment maintenance operation. The support comprises a horizontal main wire duct and two supporting frames, wherein the upper ends of the supporting frames are hinged to the main wire duct; the upper end of the main wire duct is open; a shaft seat is fixed in the middle of the lower end of the main wire duct; the two supporting frames are arranged on the two sides of the shaft seat in a mirror symmetry mode in the length direction of the main wire duct; and the supporting frame comprises supporting legs and an adjusting mechanism hinged to the supporting legs in an X-shaped crossed mode. The upper ends of the supporting legs are hinged to the main wire duct, and the lower portions of the supporting legs are provided with limiting grooves capable of being attached to the periphery of a cross arm. The adjusting mechanism comprises a buckle and an adjusting lead screw; and the upper end of the adjusting lead screw is hinged to the shaft seat, and the lower end of the adjusting lead screw is connected with the upper end of the buckle. The middle of the buckle is hinged to the supporting leg, and the lower end of the buckle is provided with a hook clamp. The hook clamp can be hooked on the inner side of the cross arm, and a swing angle limiting mechanism is arranged between the supporting foot and the buckle.

Description

technical field [0001] The invention relates to a bracket of an insulated drain wire for live equipment maintenance work, and belongs to the technical field of live overhead line maintenance. Background technique [0002] On-load operation refers to the completion of maintenance work of live equipment without power users without power failure and without load loss of the power grid. In the process of carrying out live distribution network work, it is often necessary to use the insulated drain wire as a device, but when the insulated drain wire is in use, its insulating sheath cannot directly contact the cross arm, and additional insulation shielding is required. Insulated drain wire is a key tool for load transfer in load-bearing operations, and its fixation and measures to prevent it from swinging are particularly important. [0003] When using insulated drain wires, because both ends of the insulated drain wires are connected to a voltage level of 10kV, the insulation she...

AI Technical Summary

Problems solved by technology

[0005] 1. When the existing insulated drain wire is used for operation, it is necessary to insulate and shield the surrounding electrified body and grounding body with rubber pads and insulating blankets. The shielding process takes a long time

[0006] 2 When shielding the surrounding electrified body and grounding body, the shielding may not be tight, and there are potential safety hazards

[0007] 3 When using insulating rope to fix the insulating drain wire on the wire, there may be risks such as slippage and displacement due to loose binding
