POLE TRANSFORMER WITH A BUILT-IN SENSOR CAPABLE OF MEASURING A LOAD CURRENT AND A LOAD VOLTAGE OF A SECONDARY SIDE OF A TRANSFORMER

摘要

PURPOSE: A pole transformer with a built-in sensor is provided to obtain information about the deterioration degree and temperature of insulating oil by attaching or detaching an insulating oil sensor.;CONSTITUTION: An external case(10) includes a door(20) and a receptor(22). An extra high voltage bushing is formed to connect extra high voltage power supplied from a distribution line. A first low voltage bushing and a second low voltage busing are drawn to transmit the transformed low voltage power to an external load. The first to third bushings(32,34,36) are adjacent to an attachment/detachment unit in a receiving space of the receptor. A current and voltage sensor(30) includes a current sensor unit and a voltage sensor unit.;COPYRIGHT KIPO 2012
