Problems solved by technology
However, during the implementation of differentiated lightning protection transformation, the traditional operation method of installing lightning arresters in power outages is often affected by the reliability of power supply, and cannot be installed in time for power outages, which greatly reduces the installation efficiency of line lightning arresters. If the planned power outage time encounters bad weather even more impossible
As a result, in the installation work of the line arrester, due to the influence of power supply reliability, tower structure, weather environment and other factors, it is difficult to effectively install the line arrester

Embodiment Construction
[0019] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0020] Live work is divided into equipotential, ground potential and intermediate potential work according to the position of the operator. Due to the influence of the size of the tower, the combination clearance of the operator cannot meet the requirements of safety regulations during equipotential operations, and a working platform needs to be set up for intermediate potentials. In order to improve the installation efficiency of line arresters, reduce power failure losses, and ensure the reliability of power supply, live work is adopted for the installation of line arresters. In order to reduce safety risks and labor intensity, a line arrester installation tool using an insulating operating rod at the ground potential has been devel...

The invention relates to a ground potential installation tool for a line arrester. Compared with the prior art, the ground potential installation tool for the line arrester overcomes the defect that a tool for installing a line arrester in a live environment is not provided. According to the ground potential installation tool, a transmission line is located on a line fixing hook, a middle connector is provided with a connection line fixing opening and a clamp fixing opening, the clamp fixing opening corresponds to the transmission line in position, a line arrester connecting line is fixedly installed in the connecting line fixing opening, a clamp penetrates through the clamp fixing opening and is installed in the clamp fixing opening in a threaded mode, an installation seat is arranged at one end of the clamp, the other end of the clamp is provided with a line pressing block, and when the clamp moves to the line fixing hook, the line pressing block, the transmission line and the line fixing hook are meshed with one another. According to the ground potential installation tool, by operating an insulating bar at the ground potential, power interruption is avoided when the line arrester is installed, the installation efficiency of the line arrester is improved, and the power interruption cost is reduced.
Description
technical field [0001] The invention relates to the technical field of line arresters, in particular to a ground potential installation tool for line arresters. Background technique [0002] The line arrester is one of the important lightning protection equipment on the transmission line. Its function is to protect the line from overvoltage when it is directly struck by lightning, and to avoid grounding faults on the line due to lightning strikes. With the operation of mountainous lines, especially the lines of motor vehicle traction stations, the number of lightning strikes on lines has increased year by year in recent years, which has seriously affected the safe operation of lines. Replacement and installation of line arresters. [0003] At present, the conventional installation method of line arresters is the power failure installation method. After the line is powered off, the operator goes down to the operating position along the insulator string, and uses the parall...
