Pay attention to the difference between the vacuum transformer oil filtration system and other types of transformer oil purification system to protect the safety of personnel and equipment , also to protect the safety of the transformer.
Note:
1, in the working spot, the transformer oil regeneration system should be as close to the transformer or tank, the suction line should not be too long to make system reduced the pipeline resistance.
2, connecting pipeline (including the tank) must be thoroughly cleaned, and a good seal.
3, in strict accordance with operating procedures. Subject to start the transformer oil regeneration system filter,vacuum pump, oil pump and heater running properly and to ensure good internal circulation only after the oil cycle.
4, the oil contains a large number of mechanical impurities andfree water. Prior to rule out the bottom of the water and impurities, and then the other filter devices (such as centrifugal oil filter, pressure-type oil filter) to fullyfilter out the requirements of crude oil in order to achieve the vacuum oil standard, before the vacuum oil filter to affect the oil filter service life.
5, during operation, should strictly monitor the work of the transformer oil regeneration system (such as vacuum, flow, temperature, etc.), should be regularly before and after the detection of oil processing quality (breakdown voltage, etc.). To monitor the oil filter purification.6, in the winter operations, piping, vacuum tank and other components should be used insulation measures in the substation oil filter also must comply with the relevant provisions of the electrical safe work procedures issued by the electric power industry.
