How to use the oil filter safely

1. When operating on site, the oil filter should be as close as possible to the transformer oil tank, the oil suction pipeline should be too long, try to reduce pipeline resistance.

2. The connecting pipes (including the fuel tank) must be completely clean beforehand, have outstanding airtightness.

3. Strictly follow the operating procedures. When the oil filter is started, the oil can be recycled only after the vacuum pump, oil pump heater are running normally the internal circulation is ensured.

4. The purified oil contains many mechanical impurities free water. The water impurities at the bottom must be removed beforehand, then other filtering equipment (such as centrifugal oil filter, pressure oil filter) can be used to filter thoroughly to reach the crude oil standard requested by the vacuum oil filter before the vacuum oil filter can be used. Filter to affect the service life of the oil filter.

5. During operation, the operating conditions of the oil filter should be strictly monitored (such as vacuum, flow, temperature, etc.), the quality of the oil before after treatment (breakdown voltage, etc.) should be checked regularly. To monitor the purifying effect of the oil filter.

6. When working in winter, the pipelines, vacuum tanks other components should be insulated. When filtering oil in the substation, they must also abide by the relevant regulations in the electrical safety operation regulations issued by the power industry.
