Uninterruptible circuit maintenance method

Abstract

The invention relates to an uninterruptible circuit maintenance method, which comprises the following steps that: 1, a temporary bypass is connected in parallel on an electric appliance to be maintained through a line maintenance tool, the temporary bypass comprises a temporary electric appliance, the line maintenance tool comprises a tool bracket, and a clamping conductive mechanism and a bolt screwing mechanism are arranged on the tool bracket; 2, a bolt matching head of the bolt screwing mechanism is in rotation stopping fit with a bolt on the connecting fitting, a nut matching head of the bolt screwing mechanism is in rotation stopping fit with a nut on the connecting fitting, the bolt and the nut are unscrewed, electric connection between the electric appliance to be maintained and the power transmission line is cut off, and in the maintenance process of the electric appliance to be maintained, the line maintenance tool is fixed on the connecting fitting through the clamping of the clamping conductor and the connecting fitting. The invention provides an uninterruptible circuit maintenance method which is convenient to operate and realizes maintenance of electric appliances.

Description

technical field [0001] The invention relates to a maintenance method for a non-stop circuit in the field of circuit maintenance. Background technique [0002] The existing power transmission line includes a plurality of poles, and there is a power transmission cable between adjacent poles. One end of the power transmission cable is connected to an insulator string on one of the poles through a tension clamp. The other end is connected to the insulator string of another pole through the tension clamp. [0003] The end of the power transmission cable is connected with a parallel cable through a parallel groove clamp, and the parallel cable is connected to an electrical appliance through a connecting fitting. The connecting fitting can be a terminal or a metal plate, etc. The electrical appliance is generally a circuit breaker, a fuse and other switching equipment. , When there is a problem with the electrical appliance, it is necessary to repair the electrical appliance. Duri...

AI Technical Summary

Problems solved by technology

[0003] The end of the power transmission cable is connected with a parallel cable through a parallel trench clamp, and the parallel cable is connected to the electrical appliance through the connecting hardware. The connecting hardware can be a terminal or a metal Electrical appliances are generally circuit breakers, fuses and other switching equipment. When there is a problem with the electrical appliance, it needs to be repaired. During maintenance, it is necessary to disconnect the connection between the parallel cable and the electrical appliance. If you directly disconnect the parallel cable from the The connection of electrical appliances requires power-off operation, which will undoubtedly cause inconvenience in industry or life. Therefore, how to maintain electrical appliances without power-off becomes the key to circuit maintenance.
