Embodiment Construction

[0027] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the description.

[0028] refer to figure 1 As shown, the gas-insulated metal-enclosed switchgear operation risk assessment system includes the mechanical characteristic monitoring module of gas-insulated metal-enclosed switchgear, SF 6 Moisture density monitoring module, partial discharge monitoring module, arrester status monitoring module, operating load monitoring module, health index calculation module, failure probability and operation risk calculation module and equipment maintenance suggestion output module. The mechanical characteristic monitoring part monitors the mechanical characteristic performance parameters of the switch by installing a switch contact travel sensor, a current acquisition unit and collecting auxiliary node signals on the gas-insulated metal-enclosed switch; SF 6 Micro water density partly through the i...

Abstract

The invention relates to a method for assessing operation risks of a gas insulated metal enclosed switchgear. The health index of the switchgear is calculated based on parameters including switch mechanical characteriztic parameters, SF6 gas density and humidity, partial discharge parameters, lightning arrester state parameters and the like. The operation fault probability of the switchgear is calculated according to the health index, the load history, the operating maintenance history and the basic data of the gas insulated metal enclosed switchgear, the operation risks are further calculated according to the importance and fault loss degree of the equipment, so that the corresponding assets management and condition-based maintenance suggests are provided for users.

Description

technical field [0001] The application belongs to the technical field of on-line monitoring of electrical equipment, and specifically relates to a health index model of gas-insulated metal-enclosed switchgear based on an on-line monitoring system and an operation risk assessment method. Background technique [0002] Gas-insulated metal-enclosed switchgear has the advantages of small size, high reliability, small maintenance workload, and long maintenance cycle; therefore, gas-insulated metal-enclosed switchgear (GIS) has gradually replaced conventional electrical appliances and has become a mainstream product. However, due to: (1) GIS requires high manufacturing quality, complex structure, complicated and time-consuming maintenance process, and its scope of power failure often involves non-faulty components; (2) GIS has few faults, but the consequences of failure are quite serious, and the maintenance process is required to be very fine , A little carelessness will cause new...
