APPARATUS FOR MONITORING TEMPERATURE OF POWER SYSTEM DEVICES

摘要

PURPOSE: A measuring apparatus for a power device temperature monitoring is provided to eliminate a wiring of a power line by including a self power generating unit with supplying a DC power based on an induction current. CONSTITUTION: A self power generating unit(20) supplies a DC power based on an induction current inducted by a current flowing to a power device. A temperature detecting unit(22) is operated by the DC power supplied from the self power generating unit. The temperature detecting unit detects the temperature of the power device by including a contact temperature sensor. A communications unit(23) is connected to the temperature detecting unit. The communications unit transmits a temperature data outputted from the temperature detecting unit. The contact temperature sensor is composed one among the contact temperature sensors including a Thermistor, a Thermocouple, a platinum resistance temperature sensor, a Resistance Temperature Detector.
