　　Explosion-proof Trailer vacuum oil filter is mainly used in places containing inflammable and explosive gas and dust, such as electric power, coal, petroleum and chemical industry, and may explode in the environment. Such as combustible gases, dust environment, refineries, petrochemical plants, coal mines and so on. The equipment is composed of whole explosion-proof, explosion-proof motor, explosion-proof electronic control box and explosion-proof solenoid valve. With automatic trailer, transformer insulation oil can be filtered remotely. Mainly deal with unqualified water content and impurities transformer oil, lubricants, etc. Especially for large substations above 110KV transformer site maintenance and high-grade new oil, imported oil, transformer oil, ultra-high voltage transformer oil and other deep purification treatment. It can also be used for vacuum oil injection and drying of transformers. Live work can be done on site. The machine has strong vacuum degassing ability, oil-water separation ability, particle purification ability, acid value removal, free carbon removal and impurities, etc. After treatment, the transformer oil has a high ultimate withstand voltage value, providing oil use efficiency.
