Fully-sealed capsule type oil conservator with capsule leakage detection and in-capsule water accumulation detection

A fully-sealed capsule type oil conservator with capsule leakage detection and in-capsule water accumulation detection is characterized by comprising a detector junction box, a balance valve, a detection sensor, a deflation valve, a leakage detection relay, a transformer expansion tank and a transformer capsule. A detection sensor is arranged in a transformer capsule, a signal line is led out through a moisture absorber pipeline and connected to a detector junction box, a leak detection relay is installed on the top of an oil conservator through a flange and communicated with a deflation valve, and the transformer capsule is placed in a transformer oil conservator. The full-sealed capsule type oil conservator with the capsule leakage detection function and the accumulated water detection function in the capsule has the advantages that the problem that an existing oil conservator cannot monitor the capsule leakage condition can be solved, so that the fault state of the capsule is predicted in advance, larger a
