Ring main unit equipment state monitoring and fault diagnosis method

Abstract

The invention discloses a ring main unit equipment state monitoring and fault diagnosis method, which comprises the following steps of: 1, acquiring operation data of ring main unit equipment, and determining abnormal state information of the ring main unit equipment according to the operation data; 2, acquiring equipment information of the ring main unit equipment, and generating a fault diagnosis work order according to the equipment information and the abnormal state information; step 3, according to the fault diagnosis work order, based on correlation analysis of the state data of the components and the abnormal state information, collecting state data of a plurality of related components of the ring main unit equipment; and 4, inputting the state data of the plurality of related components into the fault analysis model, and determining the fault type of the ring main unit equipment. According to the invention, the operation data of the ring main unit equipment is collected, the abnormal information of the equipment is found in time, the fault diagnosis work order is generated, the fault analysis model is used, the fault type is rapidly determined, real-time detection is realized, manual inspection is not needed, and prior information is provided for maintenance of equipment operation and maintenance personnel.

Description

technical field [0001] The invention relates to the technical field of power equipment monitoring and maintenance, in particular to a state monitoring and fault diagnosis method for ring network cabinet equipment. Background technique [0002] In recent years, my country has continuously increased investment in distribution network construction, urban distribution networks have developed rapidly, and the quality of power supply has been significantly improved. Ring network cabinets have been widely used due to their simple structure and flexible installation methods. The number of cabinets is large and scattered outdoors, which is difficult to maintain. The state monitoring and operation and maintenance inspection of primary equipment are under great pressure. With the increasing requirements for operation and maintenance of ring network cabinets, the traditional inspection work mainly relies on manual regular inspections. For inspection, the operation and maintenance personne...

[0002] In recent years, my country has continuously increased investment in distribution network construction, urban distribution network has developed rapidly, and the quality of power supply has been significantly improved. The ring main unit has been widely used due to its simple structure and flexible installation methods. There are a large number of cabinets scattered outdoors, and maintenance is difficult. The status monitoring and operation and maintenance inspection of primary equipment are under great pressure. With the increasing requirements for the operation and maintenance of ring network cabinets, the traditional inspection work mainly relies on manual inspections For inspection, operation and maintenance personnel use infrared thermometers, partial discharge detectors, sulfur hexafluoride pressure gauges and other equipment to conduct on-site inspections to evaluate the operating status of the ring network cabinet. Long-term operation in a defective state will eventually lead to power outages
