INSULATOR CONTAMINATION AMOUNT MEASURING DEVICE

摘要

PURPOSE:To reduce the size and the weight of measuring device to decrease reinforcement of steel tower at the time of mounting on a transmission steel tower and to eliminate supplement/replacement of refrigerant by providing an X-ray bulb body with radiation fins and arranging a cooling fan for blowing air toward the radiation fins. CONSTITUTION:In a device wherein an X-ray bulb body 11 is provided with multiplicity of radiation fins toward which air is fed from a cooling fan 21, the X-ray bulb body 11 is heated to high temperature when a target 15 is irradiated with electrons to emit X-ray 17. But since the heat is transmitted to the radiation fins 18 which is cooled by air blown from the cooling fan 21, the X-ray bulb body 11 is not heated abnormally. Furthermore, since the contamination of insulator is monitored based on periodic measurement of contamination amount, extended continuous operation of the X-ray bulb 3 is not required and thereby such measuring device can be applied on an X-ray bulb 3 cooling system comprising the radiation fins 18 and the cooling fan 21.
