On-load tap changers of transformers interface is used square panel structure by the present invention, is put to on-load tap changers of transformers
Oil port pressure valve circular configuration, square structure are all applicable.The present invention is put on-load tap changers of transformers by connecting tube
The external extension of hydraulic fluid port pressure valve, fuel outlet is in shower shape oil spout when avoiding draining the oil, and the pipe tail end of connecting tube is provided with non-return valve, energy
Enough close at any time is drained the oil, while also can again be connect at non-return valve and be extended pipeline to ground, avoids connecing oil in the air.
The present invention closes non-return valve and on-load tap changers of transformers fuel outlet pressure valve, directly takes after draining the oil
It uses oil in sampler to reduce the exposure duration of test oil and air as test oil, ensures the test accuracy of sample oil.
