CLEANING METHOD OF WASTE TRANSFORMER BY USING ULTRASONIC WAVES

摘要

PURPOSE: A cleaning method of a waste transformer by using ultrasonic waves is provided to prevent a new kind of waste by obtaining PCB-included insulating oil, since the surface of inner components of a waste transformer or an inner PCB is eluted using PCB(Printed Circuit Board)-free insulating oil. CONSTITUTION: A cleaning method of a waste transformer by using ultrasonic waves comprises followings. PCB-included insulating oil inside a waste transformer flows out to the outside(S11). PCB-free insulating oil flows into the inside of the waste transformer(S12). An ultrasonic oscillator is located inside the PCB-free insulating oil inside the waste transformer. The ultrasonic wave is created from the ultrasonic oscillator to elute PCB remaining in the inside of the waste transformer(S13).
