Baoding oil-immersed transformer is a kind of static electrical equipment, which is used to change the ac voltage (current) of a certain value into another voltage (current) of the same frequency or different values. Baoding oil-immersed transformer is an oil-immersed power equipment which converts the current and alternating voltage of one system into the current and voltage of another system through electromagnetic induction. It consists of an iron core and two or more windings encased thereon.
The low-voltage windings of baoding oil-immersed transformer generally adopt the cylindrical structure with copper foil around the shaft except copper wire for small capacity. The high-voltage winding adopts multi-layer cylindrical structure, so that the ampere-turns distribution of the winding is balanced, with small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.
The daily maintenance and maintenance methods of baoding oil-immersed transformer are as follows:
1. Oil sample test -- the performance indicators such as voltage resistance and impurities should be carried out every three years. The cycle can be shortened if the transformer runs at full load or overload for a long time.
2, high and low voltage insulation resistance is less than 70% of the original factory value (10 m Ω), winding dc resistance in the same temperature, the difference between the three phase average should not be greater than 2%, compared with the last measurement results should not be greater than 2%.
3. The cycle of power failure cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally once every half a year to once a year.
4. The grounding resistance value of transformer shall be measured every two years. The main contents include: removing the defects found in the inspection tour, cleaning the porcelain bushing shell, replacing the cracked or aging rubber pad, tightening the connection point inspection, filling oil for oil shortage, silicone inspection and replacement of respirator, etc.
