Problems solved by technology

However, the height of the core body of the common tank arrester is fixed, resulting in high workmanship requirements or the need for appropriate pads to adjust its installation height, which makes the assembly of the tank arrester very inconvenient and affects production efficiency.
Moreover, the commonly used tank arrester is used in an environment with high humidity and is prone to moisture, which affects its overall performance and is unsafe

Abstract

The invention discloses a core for a GIS pot-type surge arrester. The core comprises a contact base (1), a shielding device (2), an elastic device (3) and a resistor disk column (4). The contact base (1) is in matching fixing with the bottom surface of an insulator (101). The top end of the shielding device (2) is in matching connection with the bottom end of the contact base (1). The bottom end of the shielding device (2) is in matching connection with the top end of the elastic device (3). The top end of the resistor disk column (4) is in matching connection with the bottom end of the elastic device (3). The bottom end of the resistor disk column (4) is in matching connection with a pot body base (102) of the GIS pot-type surge arrester through a base sealing screw stud. Through adoption of the structure, the core is high in shielding performance and properly adjustable in height, and the core is convenient for assembly and is safe and practical.

Description

technical field [0001] The invention belongs to the field of lightning arresters, in particular to a core body of a GIS tank type lightning arrester. Background technique [0002] A surge arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards and limit the freewheeling time and often limit the freewheeling value. The main material is zinc oxide. Surge arresters are usually connected between the mains wire and the ground wire, but sometimes they are also connected next to the windings of electrical appliances or between the wires. Surge arresters are sometimes called surge protectors and surge dividers. The tank arrester is a kind of arrester. The tank type surge arrester is made of a tank type arrester, which is widely used in SF6 closed combined electrical appliances (GIS). The use of high-potential gradient zinc oxide components greatly reduces the height of the arrester. [0003] Among them, the tank body of t...
