1. The oil circuit is controlled by automatic level valve;
2. The vacuum system is equipped with vacuum equipment, and the maximum limit can reach 5pa (wheat vacuum gauge);
3. Roots pump of vacuum system adopts automatic control, which will be put into operation automatically through vacuum relay in vacuum state;
4. It is equipped with over-voltage alarm system, which will automatically shut down the machine in case of over-pressure;
5. It has oil shortage protection device, which can't be heated without oil, avoiding the hidden danger of heater burning without oil;
6. The infrared automatic deforming function can prevent the oil from entering the vacuum pump, resulting in the phenomenon of oil injection of the vacuum pump;
7. It has the function of multiple reciprocating filtrations, with coarse filtration and two fine filtration. After two times of vacuum degassing, dehydration and decolonization, it can double improve the filtration effect, so as to reach the national quality standard of transformer oil in operation;
8. According to the user's requirements, the imported real pump, booster pump, electrical control of oil drain pump and various filter elements can be selected to meet the standard of imported oil filter;
9. Effectively remove the moisture, gas and impurities in the insulating oil, improve the pressure resistance strength and oil quality of the oil, operate with electricity and evacuate the equipment separately.
