TEMPERATURE MANAGING APPARATUS FOR POWER TRANSFORMER, TEMPERATURE MANAGING SYSTEM AND TEMPERATURE MANAGING METHOD

摘要

An embodiment relates to a temperature managing apparatus for a power transformer. Particularly, disclosed are a temperature managing apparatus for a power transformer capable of preventing a temperature hunting phenomenon, a temperature managing system and a temperature managing method. For this, a temperature managing apparatus for a power transformer according to an embodiment of the prevent invention includes a temperature measuring body which is inserted into the pocket of a power transformer and measures the resistance of insulating oil, a current measuring system which measures the current of a wire through at least one current converter among current convertors formed in a local control panel, a control part which measures oil temperature by using the resistance for the temperature of the insulating oil, measures wire temperature by using the current of the wire, and measures the transformer temperature of the power transformer by using the wire temperature and the oil temperature, and a display part which digitalizes the measured transformer temperature and displays it.;COPYRIGHT KIPO 2015
