Product introduction:
The ultra-high voltage transformer vacuum oil processing system is mainly used for the vacuum degassing treatment of insulating oil to filter out the impurities in the oil, remove moisture and gas, and improve the insulation and other electrical performance indicators of the oil. The double-stage vacuum high-suction speed system can quickly and efficiently remove harmful components such as moisture, gas, and impurities from the oil, and increase the withstand voltage strength of the transformer oil. It can meet the on-site requirements for transformer vacuum pumping and vacuum oil filling. The ultra-high-precision filtering system, which is progressively encrypted, can quickly and effectively remove the mechanical impurities in the oil. The filter material has strong corrosion resistance, large dirt capacity, high mechanical strength, and is durable. The automatic constant temperature system, automatic hydraulic control system, automatic pressure protection system, and automatic defoaming control system ensure the high-performance operation of the equipment. Online oil filtering can be unmanned operation, and the operating status is indicated by the indicator light. The whole machine is equipped with interlocking safety protection, and the oil discharge system, vacuum system, and heating system are interlocked to avoid adverse effects caused by misoperation. There is a filter element replacement indicator and a filter element saturation shutdown device. There are leakage, overload shutdown devices to protect the motor. There is phase sequence and phase lack protection function, and sudden shutdown safety control.
