Abstract

The invention provides a grounding device, and belongs to the field of electrical construction and installation. The grounding device comprises a grounding electrode, an oil tank and a plurality of ground wire connecting terminals, wherein one end of the grounding electrode is inserted into the oil tank, the other end of the grounding electrode is located outside the oil tank, the grounding electrode and the oil tank are insulated from each other and matched in a sealing mode, the ground wire connecting terminals are connected to the grounding electrode, the ground wire connecting terminal is located in the oil tank, and an oil filling port, an oil discharging port and a ground wire inlet are formed in the tank wall of the oil tank. According to the invention, due to the protection of the oil tank, the ground wire connecting terminal can be prevented from being corroded by rainwater and snow water; and the tank wall of the oil tank is provided with the oil filling port and the oil discharging port, and during use, insulating oil can be injected into the oil tank through the oil filling port, and the ground wire connecting terminal is immersed through the oil, so that the ground wire connecting terminal is prevented from making contact with air, the corrosion speed of the ground wire connecting terminal is further reduced, the phenomenon that the wiring terminal is broken and disengaged is avoided, and potential safety hazards are eliminated.

Description

technical field [0001] The disclosure relates to the field of electrical construction and installation, in particular to a grounding device. Background technique [0002] Grounding refers to the neutral point of the power system and electrical devices, the exposed conductive parts of electrical equipment and the conductive parts outside the device are connected to the earth through conductors, which can be divided into working grounding, lightning protection grounding and protective grounding. [0003] The grounding grid is a general term for a grounding body that consists of multiple grounding electrodes buried in the ground at a certain depth and connected to each other by conductors to form a network structure. It is widely used in many industries such as electric power, construction, computer, industrial and mining enterprises, communication, etc., and plays the role of safety protection and shielding. At present, when making the grounding grid, the grounding wire of th...
