First of all, the transformer vacuum pump should be placed in a horizontal, ventilated and dry place, and the suction port of the vacuum unit should be well connected to the pumped system. The seal must be tight, and there should be no leakage. Check whether the oil level in the vacuum pump and the Roots pump and the lubricating oil in the oil cup meet the requirements, and connect the power cord and grounding wire. Check for other insecurities.

What is the workflow of transformer vacuum pump?
Within the temperature range controlled by the transformer vacuum pump, when a certain degree of vacuum is pumped, the evaporation and condensation of moisture in the insulating material reach a dynamic equilibrium. Due to the reduced heat conduction of the gas molecules in the vacuum tank, the moisture in the capillary pores of the insulating material cannot be absorbed. Get enough energy to turn into water vapor. At this time, a certain amount of dry air is put into the tank through a vent valve to improve the heat conduction of the gas molecules in the vacuum tank, and the insulating material transfers energy from the surface layer to the deep layer, so that the moisture in the capillary can obtain enough energy to change. The water vapor escapes and is pumped away by the vacuum pump. When a certain degree of vacuum is pumped again, a certain amount of dry air will be filled into the tank. . . .
What is the role of transformer vacuum pump?
Transformer vacuum pump is used for deep purification of ultra-high voltage transformer oil (main transformer above 110kv), new oil, imported oil, transformer oil and other more expensive oils. A two-stage vacuum unit is adopted to rapidly improve the overall vacuum degree of the system, and quickly remove moisture, gas, and particles in the oil at a lower temperature. It can effectively shorten the transformer installation and maintenance period. Especially for use in high altitude areas, it has hot oil circulation drying and vacuum oil injection for electrical equipment. Vacuum pumping and other functions.
What are the precautions for using transformer vacuum pump?
1. The oil temperature at the outlet of the transformer vacuum pump should be at least 50°C, and the highest should not exceed 70°C.
2. Pay attention to the oil quality of the transformer vacuum pump, and replace the vacuum pump oil in time.
3. Pay attention to observe the oil level of the oil accumulation window of the oil filter, and stop the machine to drain the oil in time.
Fourth, pay attention to observe the outlet pressure gauge of the filter screen of the oil filter, and replace the filter screen in time.
5. When the oil pipe is not in use, it should be tightly sealed with plastic cloth immediately to prevent moisture and impurities from entering the pipe.
6. After filtering the oil in the oil storage tank, seal the outlets of the oil tank tightly with plastic cloth in time.
7. Before the oil filter heater is put into operation, it must be confirmed that the oil level of the oil filter is normal. Before shutting down the oil filter unit, turn off the heater. Prevent the heater from burning empty and damage the equipment.
