Description

Technical Field

[0001] The present application belongs to the technical field of C-type wire clamp installation tools, and specifically relates to a C-type wire clamp lead replacement tool for live working in a distribution network using a glove method. Background Art

[0002] C-type wire clamp is a commonly used power wiring equipment, which is often used for wire clamps used in live connection operations in distribution networks to ensure tight and reliable connections and provide good electrical contact. C-type wire clamps are widely used in live operations in distribution networks, especially when working with gloves, so that one operator can efficiently complete the lead replacement operation.

[0003] When replacing the lead wire of the C-type wire clip, it is easy for the human body to be inserted into the circuit. If the power supply related to the work point is not properly disconnected before starting the work, when the worker touches the live part, it is possible for the current to pass through the human body. Although the glove method provides a certain degree of insulation protection, if the gloves are damaged, incomplete or not suitable for the current working voltage level, it cannot effectively prevent the current from passing through the human body. If the tools used are not properly insulated, or if the metal tools accidentally touch the live parts during operation, it may also cause the current to pass through the human body.

[0004] When the human body is connected to an electrical circuit, electric shock injuries occur. Severe electric shock injuries can cause violent muscle contractions, breathing difficulties, and even cardiac arrest. Depending on the path the current takes through the human body, it may affect the function of important organs such as the heart and lungs. In addition, when the current passes through human tissue, it generates heat, which may cause burns. Such burns are not limited to the surface of the skin, but may also penetrate deep into internal tissues and organs, especially at the contact points where the current enters and leaves the body, causing thermal damage to the human body.

[0005] In order to avoid the above phenomenon, a special tool is needed to realize the lead replacement operation without inserting the lead into the circuit by a single person. Summary of the invention
