It is used to fill insulation oil into oil-filled transformers, current transformer, and is also used to oil for 110-500kv transformer, canula, on load tap changer.Feature:
(1) When upper part of metal expander of the instrument transformer is pumped to high vacuum by vacuum pump, automatic oil filling can be made through oil pipe, or oil filling is done by oil pump.
Residual gas inside the pumped equipment, especially between coils is pumped off. It is more convenient and secure to inject and add oil for the equipment. It can ensure the original insulating property of the equipment.
(2)It is light and flexible, small, simple operation, convenient-to-use, low noise.Technical Parameter:
* Flow of oil pump: 5~20L/min
* lift of oil pump: 30m
* pumping rate of vacuum pump: 2L/S
* vacuum of vacuum pump: ≤ 666Pa
