Easy-to-operate permanent fastening large-load live wire connection clamp

Abstract

The invention discloses an easy-to-operate permanent fastening large-load live wire connection clamp, which comprises a hanging plate (1), a main line pressing plate (2) and a drainage line pressing plate (3), wherein a hanging ring bolt (6) at one side of the hanging plate (1) is sleeved with a spring pad (7) and a flat pad (8), passes through the main line pressing plate (2) and is screwed to the hanging plate (1); a fastening bolt (4) passes through the lower end of the hanging plate (1) and is sleeved with the drainage line pressing plate (3) and a nut is screwed for connection; two ends of a top plate (9) are provided with supporting plates (16) and lug holes (11), a wire clamping groove A (10) is arranged below the middle part, one lower side is provided with a side plate (12), the lower part of the side plate (12) is provided with a fastening bolt hole A (13) and a wire clamping groove B (14), and the protruding top end on the top plate (9) is provided with a hanging ring bolt hole A (15). The clamp has reasonable effects, operation by an operator is simple and easy, single-person single-pole operation in all directions is achieved, the operation strength of the operator islessened, and the operation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, and in particular relates to an easy-to-operate clamp for permanently fastening a large-load live wire. Background technique [0002] With the rapid development of the power grid and the continuous improvement of the requirements for power supply reliability in various industries, live work has become an important maintenance method to effectively reduce the power outage time of users, improve customer service quality, and improve the economic benefits of the power grid. "style" growth, live line fire is one of the liveline work items with a relatively large proportion, the current distribution network live fire work can be carried out by ground potential insulation rod method and intermediate potential insulation rod, insulating glove operation method, and now the There are many types of live ignition methods and wire clips used in the project. The aluminum wire winding fire m...

AI Technical Summary

Problems solved by technology

The aluminum wire winding fire method must use insulating support platforms, insulating bucket trucks and other main insulation to operate with insulating gloves. The winding method is not efficient, and there are hidden dangers in the operation when people and electrified bodies are close. When the restricted operating platform cannot be set up, it is impossible to carry out live fire work

The traditional parallel ditch line clamping method must use insulating support platforms, insulating bucket trucks and other main insulation to operate with insulating gloves. The connection efficiency is not high, there are many connection procedures for different wire diameters, and there are close operations between people and charged objects. There are hidden dangers of movement risks, and when the operation platform cannot be set up due to terrain restrictions, it is impossible to carry out live fire operations

Special-shaped and hooked wire clamps need to use special wire clamps to clamp and disengage tools when using the ground potential insulation pole operation method. The operation process is cumbersome, the operator has high skill requirements, and consumes a lot of physical energy. At the same time, the work efficiency is not good. high

Monkey head wire clip This wire clip is evolved from the current grounding hook. There is a small contact area between the wire clip and the wire, and the pressure plate bolt connected to the wire has no spring pad for continuous clamping force. After long-term operation, there is a risk of unreliable connection and heat. Hidden danger

In short, there are some special live wire clamps on the market that are difficult to connect the wire clamps and wires in parallel, poor ergonomics, high skill requirements for operators, high operating intensity, and low work efficiency.
