Use:
It is used to inject insulating oil into oil-filled transformers, current transformer, and also used to oil for 110-500kv transformer, canula, on load tap changer.
Feature:
• After the upper part of metal expander of the instrument transformer is pumped to high vacuum by vacuum pump, automatic oil filling can be made from the bottom of the oil pipe, or oil filling is done by oil pump, to the normal level of the equipment.
• Residual gas inside the pumped equipment, especially in coils is pumped off ahead. It is more convenient and secure to inject and add oil to the equipment. It can ensure the original insulating property of the equipment.
• It is light and flexible, small, convenient, easy-handling, and 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
