Abstract

The invention relates to a tank-type arrester in the field of high-voltage electrical appliance. The tank-type arrester comprises an outlet insulator, a base and a ground plate, an outlet conductor is arranged on the outlet insulator, the outlet insulator is arranged on the base, the outlet insulator is located below an outlet flange, one end of the outlet conductor stretches out of the base, and the other end of the outlet conductor is electrically connected to the ground plate. Compared with the existing arrester, the tank-type arrester is free of a conductive connection member between the outlet conductor and the ground plate and simplifies an outlet structure. The outlet conductor and a core close are arranged in a nearly coaxial way so that the electric field and potential around the core and the outlet conductor are uniformly distributed.

Description

technical field [0001] The invention relates to a tank-type lightning arrester in the field of high-voltage electrical appliances. Background technique [0002] The tank arrester is mainly used to protect the power system from overvoltage such as lightning or operation shock, so as to ensure the safe operation of the power system. [0003] The Chinese utility model patent with the authorized announcement number CN202275675U and the application date of 2011.07.18 discloses a tank-type lightning arrester, including a cylinder, the cylinder is a straight structure, the lower end of the cylinder is installed on the base, and the upper end of the cylinder A high-voltage insulator is provided, and a high-voltage conductor is provided in the middle of the high-voltage insulator; an outgoing line insulator is provided on the side of the cylinder near the base, and an outgoing line conductor is provided in the middle of the outgoing line insulator. [0004] Between the high-voltage ...
