The difference between vacuum oil filter and other types of oil filter is to ensure the safety of personnel and equipment in oil filter work and the safety of the filtered transformer. This paper introduces the matters needing attention in the operation of vacuum oil filter:
1. When used on site, the oil filter should be as close to the transformer or the oil tank as possible, and the oil suction pipeline should not be too long, so as to reduce the pipeline resistance as much as possible.
2. Connecting pipes (including fuel tank) must be thoroughly cleaned in advance and have good sealing.
3. Strictly follow the operating procedures. When starting the oil filter, the vacuum pump, oil pump and heater should operate normally and ensure good internal circulation before circulating the oil products.
4, the purified oil contains a large number of mechanical impurities and free water. The water and impurities at the bottom must be removed in advance, and then fully filtered by other filtration equipment (such as centrifugal oil filter, pressure oil filter). After meeting the crude oil standard required by vacuum oil filter, vacuum oil filter can be used for filtering to affect the service life of the oil filter.
5. During operation, the working condition of oil filter (such as vacuum degree, flow rate, temperature, etc.) should be strictly monitored, and the quality before and after oil treatment (breakdown voltage, etc.) should also be regularly tested. To monitor the purification effect of oil filter.
6. The pipeline, vacuum tank and other components of the vacuum oil filter shall adopt heat preservation measures in winter operation. In the process of oil filter in substation, the relevant provisions in the safety working rules for electric industry issued by the power industry shall be observed.
