Amorphous alloy transformer is a kind of environmental protection product with outstanding energy saving effect. With the implementation of energy policy, amorphous alloy transformer with reliable operation, energy saving and consumption reduction will be more and more valued and promoted. The NSK-BH series low voltage amorphous alloy transformer manufactured by our company is a new type, low loss, energy saving and environmental protection type developed on the basis of absorbing the advantages of international and domestic similar products. Dry type transformer A new type of magnetic material, amorphous alloy core and foil winding process coils, is adopted. The transformer has no load loss of more than 70% compared with the ordinary (silicon steel sheet as core) transformer, and the no-load current drops to 80%. It is an ideal transformer with energy saving effect.
The amorphous alloy transformer can be used for the transmission and distribution electric field of the subway, high-rise buildings, airports, stations, wharfs and factories, and the conversion voltage is used for lighting equipment, control electrical appliances power supply, numerical control system, power supply, rectifier power supply and power supply isolation. Distribution transformer is an important equipment in power distribution network and power supply and distribution system of industrial and mining enterprises. Transformers are widely used in industrial and mining enterprises, agricultural and civil buildings, and can also be used in many oil and chemical industries in petroleum and chemical industry.
Iron core: all high-quality grain oriented cold-rolled silicon steel sheets, all oblique non hole binding structure, iron core for multi-stage ladder shape, three seams or five joints, low air loss, low noise:
The coil is made of high quality QQ shrink paint, round copper wire, and flat copper coin or copper knot drawn by oxygen free copper rod. It has cylindrical, continuous, new spiral, split type and so on. It has sufficient electrical strength, mechanical strength and heat dissipation capability.
Body: the positioning structure is added to make it free from displacement during transportation, and all fastening parts are fastened with fastening nuts to ensure that the fasteners are not loosened during the long term operation and satisfy the requirements of not hanging the core.
The fuel tank is made of high quality steel plate and has elliptical and rectangular structure. The radiator is made of chip radiator, expansion radiator or corrugated oil tank, and the tank is reliably sealed in the factory. After the inner and outer surfaces are pickled and treated by phosphating, the oil paint is painted at the bottom of three times, which is both corrosion resistant and beautiful.
The selected components adopt the fully sealed transformer oil tank, and install pressure release valve, signal thermometer and gas relay according to the standard requirements, so as to ensure the safe operation of the transformer. This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.
It is safe, fireproof and pollution-free and can operate directly in the load center. It has high mechanical strength, strong short circuit resistance, small partial discharge, good thermal stability, high reliability and long service life. It has low loss, low noise and energy saving effect. It is maintenance free. Heat dissipation is good, overload capacity is strong, forced air cooling can increase capacity operation. Good moisture resistance, suitable for high humidity and other harsh environments. It can be equipped with a perfect temperature monitoring and protection system. The intelligent signal temperature control system can automatically monitor and display the working temperature of the three phase windings on the same screen. It can automatically start and stop the fan, and has the functions of alarm and trip. It has small volume, light weight, less space occupation and low installation cost.
