Title:
GAS DENSITY RELAY WITH SEALING PERFORMANCE SELF-CHECKING FUNCTION, AND IMPLEMENTATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/218287
Kind Code:
A1
Abstract:
Disclosed is a gas density relay with a sealing performance self-checking function. The gas density relay comprises a gas density relay body (1), a sealing performance checker (3) and an intelligent control unit (7), wherein the sealing performance checker (3) is in communication with a gas passage of the gas density relay body (1) or is in communication with a sealed cavity in the gas density relay body (1) to acquire gas leakage information of the gas density relay body (1); the intelligent control unit (7) is connected to the sealing performance checker (3), receives and/or calculates data or/and information monitored by the sealing performance checker (3) and performs diagnosis to acquire the current sealing performance of the gas density relay body (1); or, the intelligent control unit (7) uploads the received data and/or information to the background, and the background performs diagnosis to acquire the current sealing performance of the gas density relay body (1). Further disclosed is an implementation method for a gas density relay with a sealing performance self-checking function. Online gas leakage performance monitoring of the gas density relay is completed while monitoring the gas density of a gas insulated or arc-extinguishing electrical device, thereby reducing the operation and maintenance costs, and guaranteeing the safe operation of a power grid.
