apparatus for detecting internal disorder of ground type electric transformer

摘要

of the case on the ground transformer transformer tank outlet formed in the installation is under strain formed a convex portion, this deformation , which is installed on top of the proximity sensor , a proximity alarm means for generating an alarm in accordance with the detection signal of the sensor and a proximity sensor for at least the inner surface having a power transformer , characterized in that said detection device for driving an alarm device is disclosed. In this case , the proximity sensor of the internal error detection device is preferably installed with the second pressure reducing device on the ground transformer , forms a safety film is deformed at the moment the pressure reducing device , a proximity sensor is securely fixed to the destruction of the second pressure reducing device , obtain can be .
