technical field

The utility model belongs to the technical field of electric power maintenance equipment, in particular to a ground wire suspension device.

Background technique

In recent years, with the development of the national economy and the increasing social electricity consumption, power supply companies have paid more and more attention to the requirements of high-quality services. Ensuring the reliability of power supply and reducing power outage time are the top priorities of the work. In actual work, for the substation operation and maintenance profession, the switching operation is an important part of power stop and power transmission. Among them, the suspension ground wire is an important measure to ensure the safety of maintenance personnel and the smooth progress of maintenance work during power outage maintenance. However, when the ground wire is suspended on some equipment, due to the limitations of the field equipment conditions and the ground rod, the process of installing the ground wire is time-consuming and laborious, which often prolongs the operation time, increases the workload, and indirectly prolongs the power outage time , which is not in line with the company's high-quality service requirements, nor does it meet the society's expectations for power supply companies. Against this background, research has been conducted on the subject of shortening the grounding time.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Please refer to Figures 1-2, a grounding wire suspension device, including an insulating support rod 1 and a hook 2, the hook 2 is detachably connected to the upper end of the insulating support rod 1, and the insulating support rod 1 is divided into two parts from top to bottom. The upper section 11 and the lower section 12 are two parts, the length ratio of the upper section 11 and the lower section 12 is 1: (5~9), and a connecting piece 3 is arranged between the upper section 11 and the lower section 12; the connecting piece 3 is formed by the swing arm a4 and the swing arm The b5 is hinged together by the rotating shaft 6, the swing arm a4 is fixedly connected with the upper section 11, and the swing arm b5 is fixedly connected with the lower section 12; the swing arm a4 and the swing arm b5 are both composed of a cylinder 41 and a cuboid rod 42, and the cuboid rod Vertically welded on the outer wall of the cylinder, the free end of the cuboid rod is provided with a fixed installation hole 43; the swing arm a4 is inserted into the upper section 11 from the cross section of the upper section along its length direction, and the swing arm a4 is passed through by fastening bolts The fixed installation hole provided on the swing arm a is fixed; the swing arm b5 is inserted into the lower section from the section of the lower section along its length direction, and the swing arm b5 is fixed through the fixed installation hole provided on the swing arm b5 by fastening bolts.

Utilizing the structure of the present invention, when hanging the ground wire, as long as the angle of the hook is adjusted first, and then the ground wire is installed, one person can complete the operation of hanging the ground wire by standing directly under the equipment. It eliminates the need for another one or two people to assist in the past. At the same time, the operating time is greatly shortened.

The structure of the utility model can change the angle of the hook at will. When the grounding operation is performed on the equipment where it is difficult to find the angle to hang the grounding wire, as long as the angle of the connecting piece on the insulating support rod is adjusted, it can be directly hung on the ground directly under the equipment. There is no need to find a suitable angle, and one person can easily realize the grounding operation, and the operation time is also greatly reduced. Statistics were made on the average time for hanging the grounding wire at the main transformer bushing and other places within three months, and the operation time was shortened from more than 15 minutes to less than 7 minutes, avoiding the delay of switching operation and affecting the maintenance work , Indirectly shorten the power outage time, better guarantee the social power consumption, improve the service quality of power supply enterprises, and improve social benefits.
