Problems solved by technology

To install this kind of grounding electrode, usually use a sledgehammer to drive the grounding electrode into the ground, which is time-consuming and laborious, and some grounding bodies are not easy to pull out after being wedged into the soil; The depth is not enough and the grounding resistance is unqualified, which leads to safety hazards during maintenance; in addition, during the installation process, the installer, the operator's head and the hand-held personnel should pay attention to safety to prevent hand injuries and other injuries

Embodiment Construction

[0021] The spiral ground electrode, the installation device and its structure will be described in detail below in conjunction with the accompanying drawings.

[0022] Depend on figure 1 It can be seen that the present invention can be divided into two parts, the spiral grounding electrode and the installation device: the spiral grounding electrode 1 is the main part of the present invention, and it consists of two auxiliary threaded grounding bodies 1-5 and thread variant grounding bodies 1-4. The components form a rigid whole, the longitudinal direction of the two components is located on the same center line, and the pitch of the external thread is the same. During manufacture, it can be processed by welding; the external thread auxiliary grounding body 1-5 can be made of round long metal pipe or metal The rod is made, and its external thread is matched with the thread of sleeve barrel 2-1.

[0023] Depend on figure 2 It can be seen that the thread variation grounding bo...

Abstract

The invention discloses a screw-type earth electrode and a mounting device. The screw-type earth electrode is composed of two parts of an external thread auxiliary earth electrode and a thread variant earth body, wherein the external thread has the same thread pitch; the radius of the thread variant earth body is increased gradually from the bottom end to the top end smoothly; and the thread lower edge angle of the thread variant earth body is decreased gradually from the bottom end to the top end smoothly. The mounting device comprises an electric pole hoop, a mounting sleeve, a four-connection rod assembly, a rotating handle and an electrical power part. By adopting the above device, the fact that the maintenance operation field earth electrode mounting mode is improved, and the earth resistance is reduced becomes possible.

Description

technical field [0001] The invention relates to a power transmission line inspection and maintenance operation equipment, in particular to a spiral grounding electrode and an installation device used for the inspection and maintenance of a line with a voltage level of 35KV and below. Background technique [0002] During the maintenance of power lines, the temporary grounding wire is an indispensable safety tool. It is easy to carry and can be used flexibly on site. It is also called a portable grounding wire. human injury. Portable grounding wires include connecting wires and grounding electrodes. According to the "State Grid Corporation Electricity Safety Work Regulations", temporary grounding electrodes in power line grounding devices should have a cross-sectional area greater than 190mm, such as Round steel, temporary grounding body with an underground depth greater than 0.6m. To install this kind of grounding electrode, usually use a sledgehammer to drive the groundin...
