Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the drawings.

[0020] reference Figure 1-2 , A single-pole three-phase decomposable grounding device, comprising: a universal rotating screw bayonet clamp 1, a connection port of the bayonet clamp 2, an adjustable insulating operating rod 3; the universal rotating screw bayonet One end of the wire clamp 1 is provided with a connecting pin 11, and one end of the adjustable insulating operating rod 3 is provided with a slot 31 mated with the connecting pin; between the connecting pin 11 and the slot 31 A magnetic attraction force for mutual attraction is formed; when the slot 31 of the adjustable insulating operating rod 3 is close to the connecting pin 11, the pin 11 is automatically sucked into the slot 31.

[0021] The slot 31 also has a rotation locking device. After the connecting pin 11 is inserted into the slot 31, the adjustable insulating operating rod 3 is rotated to a certain angle and ap...

Abstract

The invention provides a single-bar three-phase decomposition type grounding device. The device is characterized in that a connecting insert column is arranged at one end of a universal rotation spiral type bayonet wire clamp, and a slot in matched insertion connection with the connecting insert column is formed in one end of an adjustable insulating bar; a rotating locking device is further arranged in the slot; after the connecting insert column is inserted into the slot, the adjustable insulating bar is rotated for a certain angle and pushed in the direction close to the universal rotation spiral type bayonet wire clamp, and the universal rotation spiral type bayonet wire clamp and the adjustable insulating bar are in locked connection; two iron sheet gears are designed on the universal rotation spiral type bayonet wire clamp, and an angle is fixed through meshing of the two gears after the angle between the universal rotation spiral type bayonet wire clamp and a wire is adjusted well; a universal gear is arranged in the universal rotation spiral type bayonet wire clamp and rotates to drive the universal rotation spiral type bayonet wire clamp to contract; a connecting port is formed in the other end of the adjustable insulating bar which can be in insertion connection with another adjustable insulating bar for length adjustment.

Description

Technical field [0001] The present invention relates to an operation method for mounting grounding transposition on a 10kV power transmission and distribution line. Background technique [0002] At present, the most commonly used grounding wire (additional universal adapter) equipment in the work, in the process of hooking the strain wire, generally encounter the following problems: [0003] 1. When the angle between the ground wire and the wire is greater than 60°, the adapter is easy to jam; [0004] 2. The insulated operating rod is easy to fall after installation; [0005] 3. The wire clamp, copper wire and operating rod of the grounding wire equipment are an integrated structure, which causes great inconvenience during on-site operation, installation and disassembly, storage and storage, which consumes too much unnecessary energy and time of the staff, and also increases The pressure of storage space in the warehouse. Summary of the invention [0006] The main technical problem ...
