Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a ground potential lightning arrester installation tool. Background Art

[0002] Lightning arrester: A device used to protect electrical equipment from high transient overvoltages caused by lightning strikes, limiting the duration and often also the amplitude of the follow-on current. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters.

[0003] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltages and limit the duration, and often also the magnitude, of the follow-on current. This term includes any external clearances necessary for the proper function of the device in its operating installation, regardless of whether it is an integral component. Lightning arresters are typically connected between the grid conductor and the ground wire, but are sometimes connected adjacent to the windings of the device or between the conductors. Lightning arresters are also sometimes called overvoltage protectors or overvoltage limiters. Lightning arresters are another important device often used to protect communication cables from lightning damage.

[0004] The existing installation methods of lightning arresters are generally divided into two types: non-energized installation and live installation. During non-energized installation, the line is out of power, and ordinary power construction workers can directly install, fix and connect the lightning arrester by hand. Due to the increasing domestic requirements for power supply reliability, the proportion of live work is also increasing. During live installation, since the main line is energized, professional live work maintenance personnel are generally required to take various insulation protection measures, such as using an insulated boom truck, a large number of insulating shielding covers and insulating blankets, and other auxiliary insulation coverings. After that, the live work maintenance personnel will approach the live body and manually install the lightning arrester and connect the lightning arrester using the insulating glove operation method. The operation process is relatively complicated, the operation is difficult, the safety risk is high, and the operation time is long. Current lightning arresters lack a suitable installation tool.
