Double stage vacuum oil filter, mainly used forPurification equipment for insulation oil of 500KV and below transmission and transformation equipment, which can discharge water, gas, and impurities particles in the oil, improve the insulation strength and oil quality of the oil, and ensure the safe operation of electrical equipment. Therefore, it can be used for insulation oil purification treatment and vacuum oil injection and hot oil circulation drying of high-voltage electrical equipment in electrical manufacturers such as transformers, transformers, power capacitors, high-voltage switches, insulated conduits, power plants, power supply bureaus, railway transformer areas, and power transmission and transformation construction departments.

Main technical parameters

The two-stage vacuum oil filter has the following characteristics:

Degassing, dehydrating, and removing impurities from transformer oil.

Can be right30 ton transformer undergoes cyclic drying treatment (the oil content of the transformer can be higher, but the processing time is relatively longer)

Guaranteed performance indicators:

The initial moisture content of transformer oil is50ppm (when it is greater than 50ppm, the water is already in a free state), with a gas content of less than 12%. After treatment, the measured values at the oil filter are as follows:

After one to three rounds of filtration

The breakdown voltage is greater than75KV

Moisture content less than5ppm

Gas content less than0.1%

Filtering accuracy≤1-5μm

Transformer vacuum extraction: Unit vacuum≤5pa
