PROBLEM TO BE SOLVED: To provide a temperature measuring apparatus for winding of molded transformer, by which the temperature of the winding can be measured and displayed continuously, precisely and without a time delay even during power- applied operation, which can be used even when a thermometer body and a thermosensitive part are made of a metal and which can be used irrespective of the kind of a temperature detector or a thermometer such as a thermocouple thermometer, a resistance temperature sensor or the like. SOLUTION: The lower part of a pipe-shaped heat pump 1 which is made of a nonflammable resin is inserted into a molded resin part 4 as a temperature measuring part at a molded winding 3 which is molded with a resin, its lower end is fixed so as to come into contact with the upper end of the winding 3, the upper part of the heat pump 1 protrudes to the outside of the molded resin part 4, and a temp. sensing part 5 at a thermometer is inserted into a recessed part which is formed at the upper end of the heat pump 1. In this manner, the temp. sensing part 5 at the thermometer is inserted into the upper part of the heat pump 1, its lower part is inserted into the molded resin part 4 so as to come into direct contact with the winding 3, and a temperature measuring apparatus for a winding at molded transformers is constituted. |
