Detachable wire clamp for live-line lead connection operation

Abstract

The invention discloses a detachable wire clamp for live-line lead connection operation, and the clamp comprises a bottom plate and a vertical column vertically arranged at the top end of the bottom plate; an arc-shaped plate is arranged at the top end of the vertical column, an arc-shaped groove is formed in the bottom end of the arc-shaped plate, a hole is formed in one side of the arc-shaped plate, a clamping mechanism matched with the hole is arranged in the hole, and the vertical column is of a cavity structure; a vertically-arranged lead screw is arranged in the stand column, the lead screw is sleeved with a sliding block matched with the lead screw, and a transverse plate extending out of the stand column and located below the arc-shaped groove is arranged on one side of the slidingblock. The beneficial effects are that the contact area between the wire clamp and the main wire is changed, and the current carrying capacity of the wire clamp is further adjusted, so the wire clampwith the structure can meet the requirement of stable live-line lap joint of drainage wires for the main wires of different specifications and models; as the contact area between the wire clamp and the main wires is adjustable, by increasing the contact area between the wire clamp and the main wire, so the connection performance of the wire clamp and the main wire is better, and the smooth conduction of the hot-line work process is ensured.

Description

technical field [0001] The invention relates to an auxiliary tool used in the field of electric power, in particular to a detachable wire clip for the operation of connecting lead wires with electricity. Background technique [0002] Lap connection of live wires is a common operation method for existing power transmission and distribution lines. At present, the operation method of insulating operating rods is often used to overlap the draining wires and high-voltage bare wires. Generally, insulating operating rods with sleeves are used to replace operators. Fix the clamp with locking bolts to the high-voltage bare wire by using the hand movement of the operator. In this way, since the operator does not need to be close to the high-voltage electric field, the operation of the live lap drain wire is safer. [0003] At present, the commonly used clips for lapping and draining wires are generally provided with a slot for matching with the wire, and a locking bolt that can pass t...

Problems solved by technology

[0003] At present, the commonly used clips for lapping and draining wires are generally provided with a slot for matching with the wire, and a locking bolt that can pass through the slot and limit the wire in the slot is provided on one side of the slot. Match the sleeve on the top of the insulating operating rod with the locking bolt, and turn the insulating operating rod so that the locking bolt clamps the wire in the slot. As a result, one clamp can only be used to clamp one type of wire, and the scope of application is small. At the same time, a single locking bolt is in contact with the wire. It is not easy to confirm the alignment of the wire clamp to the wire due to the long distance between the operators. The clamping situation is prone to too small contact area between the clamp and the wire, resulting in poor connection performance between the clamp and the wire, and a small current flow, which affects the smooth progress of the live work of the transmission and distribution line
