The basic structural components of transformer are composed of iron core, winding and insulation. In addition, fuel tanks, refrigeration equipment, and maintenance equipment were installed for reliable operation.
Core: The core of the transformer is the path of the magnetic field line, which has the effect of concentrating and strengthening the magnetic flux, and is used to support the winding together.
Winding: the winding of the transformer is the path of the current. The current is connected through the winding and the induced EMF is generated by the electromagnetic induction effect.
Oil tank: the oil tank is the shell of the oil-
Immersed Transformer. The transformer body is placed in an oil tank, which is filled with transformer oil.
Oil storage tank: oil storage tank is also known as auxiliary oil tank. This is a bucket descriptor made of steel plates. It is installed horizontally on the transformer oil tank cover and connected with the oil tank with a curved nozzle. An oil level indicator is installed at one end of the oil storage tank. The volume of the oil storage tank is generally 8 ~ 10 percent of the oil volume of the transformer tank. The result is that the transformer is full of oil. As the oil level in the oil storage tank is at a certain value, there is room for manoeuvability when the oil expands and shortens at different temperatures, and the spare position in the oil storage tank is smaller, so there is less oil and air contact, reducing the possibility of moisture and oxidation of the oil. In addition, the oil temperature in the tank is much lower than the oil temperature in the upper part of the tank, which is almost not conducive to the oil convection in the tank. A gas relay is installed on the connecting pipe between the storage tank and the oil tank to reflect the internal fault of the transformer.
Respirators: Respirators are equipped with desiccants, namely silica gel, which are used to absorb moisture in the air.
Oil purifier: also known as temperature filter. The main body is a cylindrical clean oil tank connected by electric welding of steel plate, which is installed on the side of the transformer oil tank. The tank is filled with silica gel, activated alumina and other adsorbents. During operation, due to the temperature difference between the upper oil and the lower oil, the transformer oil moves from top to bottom and forms convection through the oil purifier. The oil comes into contact with the adsorbent, and water, acids, and oxides are absorbed to purify the oil. The strong oil circulation transformer oil purifier makes the transformer oil flow through the clean oil pump through the oil flow pressure difference, so as to achieve the purpose of purification and prolong the service life of the oil.
Xuzhou transformer manufacturer -- explosion-proof tube: explosion-proof tube is installed on the transformer oil tank cover. The top of the explosion-proof tube is equipped with a glass plate. When there is a problem with the transformer and high pressure occurs, the gas in the oil will penetrate the glass plate and discharge to the outside of the tank, releasing the pressure and then keeping the transformer tank free from damage.
Thermometer: the thermometer is installed in the side temperature cylinder on the tank cover, used to measure the upper oil temperature in the tank.
Bushing: bushing is the transformer high and low voltage winding leads to the outside of the oil tank insulation equipment. It is not only the insulation of the wire to the ground (shell), but also assumes the role of fixing the wire.
Refrigeration equipment: Refrigeration equipment is the equipment that releases the heat generated by the transformer during operation.
