Abstract

The invention provides a transformer monitoring device and a fault diagnosis method. The device comprises an oil dissolved gas chromatography on-line monitoring unit, an oil trace moisture tester, a temperature monitoring unit, a partial discharge monitoring unit, a grounding current on-line monitoring unit, a transformer and on-load voltage regulation switch vibration monitoring unit, and a main station computer. Based on the transformer monitoring device and method provided by the invention, the fault of a transformer can be monitored and diagnosed by a variety of monitoring units and monitoring methods. Therefore, the monitoring accuracy is improved.

Description

technical field [0001] The invention relates to the field of power system transformers, in particular to a transformer monitoring device and a fault diagnosis method. Background technique [0002] With the advancement of west-to-east power transmission, north-south mutual supply, and national networking, the scale of my country's power grid and the scale of power transmission are constantly expanding, and grid security issues have become increasingly prominent. The "8.14" blackout in the United States and Canada, the "11.4" blackout in Western Europe and other internationally influential blackouts in recent years have caused huge economic losses and produced adverse social impacts. According to the statistics of power grid accidents during the "Eleventh Five-Year Plan" period in my country, power equipment failures account for the first cause of power grid accidents. Therefore, the safe operation of power equipment is the first defense system to avoid major accidents in the...
