Abstract

PURPOSE: To enable accurate temperature measurement, by relatively comparing the output of respective temperature detection section provided at the two or more connection sections.
CONSTITUTION: The temperature detection sections 17A, 17M, 17B are fitted to the tank 3 corresponding to the contact section between the moving connection section and the contactor. The output of the temperature detection circuit connects the judgement circuits 31, 32 and the display circuit 33 via the wiring 25. The judgement circuit 31 operated when the temperature is detected by either one of the temperature detection sections 17A, 17B. The judgement circuit 32 is operative when one of the temperature detection sections 17M, 18M, 19M detects the temperature.
