Abstract

The invention provides a method for reducing the failure rate of a high-capacity multi-column parallel lightning arrester, and the method comprises the steps: employing a layered structure for the resistor disc of the lightning arrester, and guaranteeing that the safety coefficient of the energy absorption capability of the lightning arrester is not less than 1.1; when any column in any layer of the resistor disc layered structure of the lightning arrester is short-circuited due to a failure, the energy absorption capability of other layers can meet the system requirements, the normal and safeoperation of the lightning arrester in corresponding time is ensured, and the failure rate of the high-capacity multi-column parallel lightning arrester is reduced.

Description

technical field [0001] The application relates to the technical field of compensation devices, in particular to a method for reducing the failure rate of a large-capacity multi-column parallel arrester. Background technique [0002] The main function of the large-capacity multi-column parallel arrester is to absorb the redundant energy of the system and limit the overvoltage. However, due to the large number of parallel columns of this arrester, the failure rate has always been high. Contents of the invention [0003] The present application provides a method for reducing the failure rate of a large-capacity multi-column parallel lightning arrester, which is used to reduce the failure rate of a large-capacity multi-column parallel lightning arrester. [0004] This application provides a method for reducing the failure rate of a large-capacity multi-column parallel arrester, including: [0005] Adopt a layered structure for the resistive sheet of the arrester, and ensure ...
