Abstract

The invention discloses a metallic oxide lightning arrester with a built-in insulation base. The metallic oxide lighting arrester with the built-in insulation base is characterized by comprising an aluminum cushion block, a screw, an insulation base, an aluminum electrode, a counter and base bolt, wherein the aluminum cushion block and the insulation base are arranged in the tail part of a core unit of the lightning arrester and clamped between a resistor disc and the aluminum electrode, a screw hole is formed in the aluminum block, one end of the screw is screwed into the aluminum, and the other end of the screw is arranged outside a silicone rubber case of the lightning arrester; the screw is connected with one end of the counter, and the other end of the counter is connected to the base bolt of the lightning arrester. According to the lightning arrester with the structure, the short circuit phenomenon of the counter in the rainy weather can be effectively prevented, and accordingly the effective on-line detection of the discharge counter on the lightning arrester can be guaranteed.

Description

technical field [0001] The invention relates to a composite jacket type metal oxide arrester, in particular to a metal oxide arrester with a built-in insulating base. Background technique [0002] The arrester is an important device to protect the normal operation of high-voltage electrical equipment. Therefore, during the operation of the power system, the discharge of the arrester is usually detected online by a discharge counter, so as to monitor and measure the integrity, maintenance, and life cycle of the arrester. Timely replacement or maintenance can ensure the reliable operation of the power system and avoid equipment accidents. The discharge counter is generally installed on the base of the arrester. The base is composed of two steel plates with an insulating block placed in the middle. The discharge counter can be connected to the two steel plates through wires to complete the series installation. In the case of rainy weather, the insulation part of the arrester b...
