Baoding oil-immersed transformer is a kind of static electrical equipment, is used to a certain value of ac voltage (current) into the same frequency of one or more of the following numerical different voltage (current) of the equipment. Baoding oil-immersed transformer is an oil-immersed power equipment that converts the current and ac voltage of one system into the current and voltage of another system through electromagnetic induction. Consists of an iron core and two or more windings encased on it.
The low voltage winding of baoding oil-immersed transformer usually adopts the cylinder structure of copper foil winding shaft except copper conductor for small capacity. The high-voltage winding adopts multi-layer cylinder structure, which makes the winding's ampere-turn distribution balanced, less magnetic leakage, high mechanical strength and strong short-circuit resistance.
The daily maintenance and maintenance methods of the baoding oil-immersed transformer are as follows:
1. Oil sample testing -- performance indicators such as pressure resistance and impurities shall be carried out once every three years. If the transformer is running at full load or overload for a long time, the period can be shortened.
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 period of power failure cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year.
4. The working grounding resistance of the transformer is measured every two years. The main contents include: removing defects found in inspection, cleaning porcelain casing, replacing broken or aged rubber gaskets, tightening joint point inspection, filling oil for oil shortage and replacing silicone rubber of respirator, etc.
