Description

Easy to operate and permanently fasten the heavy load live wire clamp

technical field

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

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 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. When the operation platform cannot be set up due to terrain restrictions, it is impossible to carry out live and 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 clamps and wires in parallel, poor ergonomics, high skill requirements for operators, high operating intensity, and low work efficiency.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a man clamp with reasonable effect, simple and easy operation for the operator, all-round single-rod operation, which reduces the intensity of the work of the staff and shortens the working time. It is easy to operate and permanently tightened. Solid large load live wire clamp.

The purpose of the present invention and its main technical problems are solved by adopting the following technical solutions:
