Dismantling method of waste transformer which has been purified by polychlorinated biphenyls (PCBs) using mobile purification process equipment

摘要

PURPOSE: A disassembling method of a waste transformer is provided to safely separate polluted insulating oil after purifying, and to prevent the contamination of the insulating oil by an operator during a treatment process. CONSTITUTION: A disassembling method of a waste transformer comprises the following steps: purifying polluted insulating oil by reducing the concentration of polychlorinated biphenyl less than 2ppm(S1); oil-draining the purified insulating oil to a tank lorry of a vehicle(S2); washing the insulating oil with a washing solution(S3); drying the inside of the waste transformer with a blower and a heater(S4); disassembling the dried waste transformer(S6); and transporting the disassembled waste transformer(S7).
