Embodiment Construction
[0026] A transformer to be cleaned using the system of the embodiment is an electrical device that converts the voltage of AC power, and has a plurality of magnetically coupled coils as its main component. Transformers include oil-immersed transformers, molded transformers, and gas transformers depending on the type of insulator, but this specification specifically refers to oil-immersed transformers that use oil as an insulator. Oil-immersed transformers include large equipment with an oil capacity of tens of thousands to hundreds of thousands of liters, medium-sized equipment with an oil capacity of hundreds to thousands of liters, and small equipment with an oil capacity of hundreds of liters or less. PCBs were once used in the insulating oil of oil-immersed transformers, and there are a large number of transformers with residual PCBs in them without treatment. The remaining transformers that are difficult to dispose of in this way are targeted for cleaning in this form. T...

According to the invention, a transformer polluted by polychlorinated biphenyl is efficiently cleaned by using a small amount of cleaning agent. The invention relates to a cleaning system of a transformer and a cleaning method using the cleaning system. The invention provides the cleaning system for cleaning the transformer. The cleaning system at least comprises a gasification cleaning tank, a heating device, a cooler, a cleaning agent storage container connected to the cooler, a liquid feeding pump connected to the cleaning agent storage container, a liquefying device and a pressure reducing device. Thetransformer contaminated by polychlorinated biphenyls is disposed inside the gasification cleaning tank by the cleaning system, a cleaning agent is supplied to the inside of the gasification cleaning tank, the inside of the gasification cleaning tank is brought to a pressure lower than atmospheric pressure, the gasification cleaning tank is heated to gasify the cleaning agent, and the transformer is cleaned by the gasified cleaning agent. The gasified cleaning agent is liquefied by the cooler and the liquefying device, the liquefied cleaning agent is temporarily stored in the cleaning agent storage container, and the temporarily stored cleaning agent is returned to the inner side of the transformer arranged on the inner side of the gasification cleaning tank by the liquid delivery pump, so that the transformer is efficiently cleaned.
Description
technical field [0001] The invention relates to a system for cleaning residual oil in a transformer with a cleaning agent and a cleaning method for a transformer using the system. Background technique [0002] At present, the problem of environmental pollution is becoming more and more serious, and it is difficult to directly discard industrial waste. In particular, industrial waste containing hazardous substances requires work to remove the hazardous substances by washing or the like. For example, polychlorinated biphenyls are well soluble in organic solvents or oils because of their good electrical insulation, so they have been widely used in transformers (transformers) of electrical equipment, insulating oils for capacitors, adhesives, waxes, lubricants, etc. oil etc. However, polychlorinated biphenyls are highly toxic to organisms, can cause cancer, skin damage, internal organ damage, hormone abnormalities, etc., and have the property of easily accumulating in adipose ...
