Problems solved by technology

[0003] For the above problems, domestic and foreign researches mainly focus on GIS failure mode recognition, but there are few researches on GIS partial discharge rapid recognition, and there are problems of false positives and missed negatives in GIS abnormal detection, and the accuracy of abnormal detection is relatively low. Low, for example, for GIS abnormal detection, there are problems of false positives and false negatives in the alarm process of the partial discharge online monitoring system

Abstract

The invention discloses a rapid abnormity detecting method of a GIS device. The method includes the steps of obtaining a discharge amount daily average value of the GIS device, selecting the accumulation day number n and calculating the accumulated discharge amount x of the GIS device in n days, calculating an accumulated discharge amount threshold m in the n days according to a preset daily discharge amount threshold m1, and judging whether abnormity happens to the GIS device when the accumulated discharge amount x in the n days is larger than or equal to m. By means of the method, the problem of GIS rapid abnormity detecting is solved, the abnormal local discharge phenomenon in the GIS can be accurately found in time, the judgment result is accurate and timely, misinformation caused by external interference is effectively avoided, and the accuracy of abnormity detecting is achieved by means of the method.

Description

technical field [0001] The invention relates to the technical field of power equipment monitoring, in particular to a method for quickly detecting abnormalities of GIS equipment. Background technique [0002] At present, GIS (Gas Insulated Switchgear, gas insulated fully enclosed combined electrical appliances) equipment is widely used due to its small size, beautiful appearance, convenient installation, small footprint, and excellent performance. However, during the manufacture, assembly and operation of GIS equipment, metal particles, insulating air gaps, etc. may be generated, resulting in partial discharge defects in the insulator, which may endanger the insulation and cause insulation breakdown accidents. Therefore, it is of great significance to ensure the safe and stable operation of GIS to timely and accurately discover the abnormal phenomenon of partial discharge in GIS through corresponding methods. [0003] For the above problems, domestic and foreign researches ...
