Combined metal oxide arrester structure

Abstract

The invention discloses a combined metal oxide lightning arrester structure in the technical field of lightning arresters, and the combined metal oxide lightning arrester structure comprises a metal oxide lightning arrester body, a threaded connection part, a connection ring and the like; a nail penetrates through a positioning hole to fix an L-shaped connection plate and a mounting plane, so a left holding ring and a right holding ring are fixed on the mounting plane, and the lightning arrester body is fixed on the left holding ring and the right holding ring. The fastening nut is screwed on the fastening bolt, so that when the left embracing ring and the right embracing ring play a role in fastening the metal oxide lightning arrester body, the connection between the left embracing ring and the connecting ring and the connection between the right embracing ring and the connecting ring are firmer through the connection between the annular connecting groove and the arc-shaped connecting sleeve, and meanwhile, the contact damage to the metal oxide lightning arrester body is avoided.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a combined metal oxide lightning arrester structure. Background technique [0002] The lightning arrester is a device connected between the wire and the ground to prevent lightning strikes. It is usually connected in parallel with the protected equipment. The lightning arrester can effectively protect the electrical equipment. Once an abnormal voltage occurs, the lightning arrester will work and play a protective role. When the protected equipment When operating under normal working voltage, the arrester will not work, and it is regarded as an open circuit to the ground. Once a high voltage appears and endangers the insulation of the protected equipment, the arrester will act immediately to guide the high-voltage surge current to the earth, thereby limiting the voltage. Amplitude, to protect the insulation of electrical equipment; when the voltage disappears, the arre...

AI Technical Summary

Problems solved by technology

[0004] During the use of the metal oxide arrester, its two ends are the high-voltage connection end and the grounding end, which need to be connected to the high-voltage line and the earth respectively. Since the metal oxide arrester is cylindrical, the current connection between the metal oxide arrester and the installation plane The method is directly connected to the metal oxide arrester through the hoop. This connection method has poor connection firmness, and the rigid contact between the metal oxide arrester and the hoop is easy to be damaged. Therefore, a combined metal oxide arrester is proposed. structure
