Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance equipment, and in particular to a lead fixing and temporary suspension device for non-stop power supply operation of a distribution network. Background Art

[0002] With the rapid development of the economy and society, the stable and reliable supply of electricity has become increasingly important. Uninterrupted operation of distribution networks is an important means to improve the reliability of power supply. Through continuous innovation and expansion, there are now more and more uninterrupted operation projects for distribution networks that can be carried out.

[0003] At present, the technical conditions for ensuring the safety of live distribution network operations are: (1) the current flowing through the human body does not exceed the human perception level of 1mA; (2) the local field strength on the human body surface does not exceed the human perception level of 240kV / m; (3) the human body and the live body (or grounding body) maintain the specified safety distance (air gap). Due to the compact structure and small phase-to-phase distance of distribution network equipment, the maintenance of distribution network equipment under some special structures is mainly carried out by power outage due to the insufficient safety distance (air gap) between the human body and the live body (or grounding body). Therefore, it is necessary to develop new tools with the help of which the branch line leads, tension leads and cable terminal leads can be quickly fixed, and operation plans can be proposed to solve the problems of insufficient safety distance (air gap) between the human body and the live body (or grounding body) during the maintenance of distribution network equipment under special structures, and to carry out maintenance work without power outage. Once realized, it will be of great significance.

[0004] For the maintenance of distribution network equipment under special structures, the safety distance (air gap) between the human body and the live body (or grounding body) is insufficient. If you want to carry out maintenance work without power outage, you must solve the problem of fast fixing and safe hanging of live leads. At present, for the non-stop cutting, connection and non-stop switch replacement operations of 10kV distribution network, the cut or to-be-connected drainage lines need to be temporarily fixed on the tower crossbars, and the safe distance of each phase should be maintained. Usually, the safe distance between the drainage line and the main line is not less than 0.4m. When fixing and removing the drainage line, the staff needs to control the insulated boom truck to move up and down more frequently to complete the function. This process increases the scope of operation and the number of times the boom truck is controlled. In addition, the drainage line is not firmly fixed, and the safe distance is difficult to grasp, which increases the risk of live work. Summary of the invention
