Electric operating fuse wire protector without electricity failure

Abstract

An electric operating fuse wire protector without electricity failure comprises a conductor gripper capable of being electrically connected with a single-phase conductor entering end of a circuitry to be repaired and gripping a single-phase conductor, an insulated supporting bar which is fixedly connected with the conductor gripper, a fixed contact which is electrically connected with the single-phase conductor entering end of the circuitry to be repaired, a supporting bracket which is arranged on the lower end of the insulated supporting bar and is connected with the insulated supporting bar, and a fuse protector tube which is connected with the supporting bracket and is movably and freely contacted and electrically connected with the fixed contact. The lower end of the fuse protector tube is electrically connected with a single-phase conductor entering end of an energy supply user. An exchanging and closing fuse wire protector of a connected conduction wire can protect equipment in a phase circuitry and repairers working with electricity in case that overvoltage electric current enters, when the operations of repair, exchange, and the like of a 10kV electricity transmission circuitry and the fuse protector of the 10kV electricity transmission circuitry without electricity failure are carried out, serious potential safety hazard problems such as the abnormal operation of the circuitry, the damage of the equipment, the casualty accident of workers, and the like are avoided, and the working strength of operating workers is also reduced.

Description

technical field [0001] The invention relates to a construction protection device for electric power operation, in particular, the invention relates to a fuse protection device for non-stop power operation. Background technique [0002] So far, in the power supply of cities, enterprises, etc. by 10kv and below transmission lines, in order to ensure the safety of power supply, usually in the connection between the three-phase power supply line and the transformer of the power supply user, respectively, between the three-phase line and the transformer A fault fuse is set between them. Once an overvoltage current flows in, the fault fuse will blow the fuse to protect the electrical equipment of the power supply user. [0003] However, when the above-mentioned 10kv and lower transmission lines need to be overhauled and replaced, or when the above-mentioned fuses are damaged, the above-mentioned single-phase or three-phase circuits must be temporarily interrupted. [0004] At thi...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide a fuse protection device for non-stop power operation, which can effectively solve the problem of When the above-mentioned 10kv and below transmission lines and their fuses are repaired and replaced without power failure, once the overvoltage current flows into the phase line, the equipment and live maintenance personnel lose protection for a period of time, and the line leapfrogs Actions, causing equipment damage and casualties and other serious safety hazards
