Background
With the continuous expansion of the scale of the power grid, the power industry in China is also continuously developed, the power supply quantity is increased year by year, and the power transformer is gradually developed into high-voltage and large-capacity power equipment. The high-voltage bushing is used as important equipment of a power system, can insulate the outgoing line of the transformer winding from the transformer shell, plays a role in fixing the outgoing line, and guarantees safe operation of the transformer. However, high voltage bushings may suffer from micro-cracks during production manufacturing, loss of mechanical strength due to aging, repeated thermal cycling (load + sunlight), contamination, flashover of molten porcelain, sludge and moisture in the insulating oil, and reduction of product size and weight to reduce costs, bringing the bushing close to design limits, which may cause a risk of high voltage bushing failure. In addition, due to the thermal effect influence of line voltage and current, the transformer bushing can be continuously in a high risk state, so that monitoring the transformer bushing is very important for ensuring the normal operation of the transformer.
With the rapid development of modern electronic technology, continuous monitoring of transformer bushings has become possible. The transformer bushing can be monitored on line through remote data access. At present, according to the statistics of the faults of the bushing and the CT in recent years, the proportion of faults of partial discharge, suspension discharge and spark discharge is almost 100 percent. The characteristic gas in the partial discharge, suspension discharge and spark discharge insulating oil contains hydrogen (generally more than 2000 ppm). There is a need for a monitoring system that monitors the casing very well.
