摘要
油浸式互感器的防爆问题已经引起了广泛的重视。电科院高压研究所与有关单位合作,在大电流试验室和电力系统中进行了互感器防爆模拟试验。本文在大量试验的基础上进行了理论分析,对互感器在发生贯穿性击穿前后的内部压力变化和压力传递速度做了详细的描述。文章认为,金属膨胀器和压力释放装置都不能解决互感器的防爆问题。
The explosion faults of oil-filled instrument transformers in service have been investigated. The tests have been carried out in the laboratory of Electric Power Research Institute and Tangshau substation. The Pressure propagation and distribution inside porcelain container during the explosion process has been analyzed. The results show that using bellows and/or pressure relief device is can not effective protect explosion.
