A 10kv on-column vacuum switch state evaluation method based on multi-source data

Abstract

A 10kV on-column vacuum switch state evaluation method based on multi-source data. The method builds a mathematical model for the state evaluation of the on-column vacuum switch by fusing the state quantities of the on-column vacuum switch, and realizes on-line monitoring and monitoring of the health status of the on-column vacuum switch. Evaluation. The state quantity of the vacuum switch on the 10kV column includes the lightning parameter state quantity, the temperature state quantity of the FTU battery, the communication state quantity, the transformer state quantity, the FTU battery voltage state quantity, the switch opening and closing state quantity, the opening time state quantity, The state quantity of breaking characteristics, the state quantity of switch refusal to operate, the state quantity of switch misoperation, and the maintenance state caused by service life, defect or failure. The present invention classifies the device states through information fusion and visualization technology, and quickly and clearly displays the basic information of the device, the state of each parameter and the state score. The present invention considers the defect repair coefficient and the service life coefficient on the original evaluation model, and the evaluation mathematical model is more in line with the actual operation and maintenance situation.

Description

technical field [0001] The invention relates to a method for evaluating the state of a vacuum switch on a 10kV column based on multi-source data, belonging to the technical field of electric switches. Background technique [0002] With the development of social economy and the continuous improvement of people's living standards, users have higher and higher requirements for the reliability of power supply. Traditional planned maintenance or preventive maintenance needs to cut off the power grid in different areas, so as to carry out maintenance of electrical equipment. Cause greater waste and increase maintenance costs. "Distribution Network Equipment Condition Maintenance Test Regulations" (Q / GDW 643-2011), "Distribution Network Equipment Condition Maintenance Guidelines" (Q / GDW 644-2011), "Distribution Network Equipment Condition Evaluation Guidelines" (Q / GDW 645 -2011) put forward the state quantity and evaluation method of the 10kV on-column vacuum switch. The state qua...

Problems solved by technology

According to the degree of influence of the state quantity itself on the safe operation of the equipment, the corresponding maintenance strategy is formulated. However, this method mainly relies on regular inspections, live detection, routine tests and other data for regular or dynamic evaluation. The inspection takes a long time, and the difficulty in obtaining the status data will delay the research and judgment of the health status of the equipment
