[0002] Bypass operation is to temporarily replace the distribution line with power supply through the transfer line, and to cut off the power supply for maintenance of the high-voltage line and its electrical equipment that need to be repaired without interrupting the power supply to users. Except for live work at both ends of the bypass, the operators do not need to work live in the maintenance work area. The contents of bypass operation include testing, inspection, maintenance, replacement of equipment, etc. The operation objects include high-voltage electrical equipment such as substation electrical equipment, overhead transmission lines, distribution lines and distribution equipment. The equipment used includes insulated aerial work vehicles, emergency bypass cable cars, bypass operation tool warehouse cars, emergency bypass distribution vehicles, mobile ring network cabinet vehicles, mobile load switch vehicles, etc.

[0003] At present, the technology for non-stop power supply operation for overhead lines is very mature. The access method of overhead line bypass power supply is single, and the form of live operation jumper lead line is generally adopted. With the continuous improvement of the cableization rate of urban distribution networks, the demand for non-stop power supply operation of cable networks is increasing. In order to carry out non-stop power supply operation of cable networks, the problem of bypass power supply access should be solved first. The use of bypass cables can solve the problem of pure cable networks being unable to obtain power supply faced by conventional live operations. By connecting the bypass cables to the spare interval switches of the ring network cabinets at both ends of the line section, the power supply is directed to the load side, so that the equipment can be shut down for maintenance without power outages to users during the entire operation process.

[0004] In the installation of bypass cables, it is necessary to accurately, firmly and stably suspend and fix the bypass cables. For example, the ground part of the bypass cable needs to be suspended. If the ground is damp, there will be corresponding safety hazards. At the same time, if the ground part of the bypass cable is placed randomly, it will cause the working surface to be disordered and unsafe, which also poses safety hazards.

[0005] Therefore, based on the above problem, the utility model provides a ground fixing bracket for a bypass cable. Utility Model Content
