The description of SH15 amorphous alloy transformer
SH15 amorphous alloy transformer is widely used in some lighting, high-rise construction, airport, terminal CNC machinery and other occasions. Briefly speaking, dry-type transformer refers to the transformer whose core and winding are not immersed in insulating oil.
The cooling methods of SH15 amorphous alloy transformer are divided into natural air cooling (AN) and forced air cooling (AF).
In natural air cooling, the SH15 amorphous alloy transformer can work continuously for a long time with additional capacity.When forced to cool, the output capacity of the transformer can be improved by 50%.
SH15 amorphous alloy transformer is suitable for intermittent overload work, or emergency overload work. Because the load loss and impedance voltage increase greatly during overload and it is in a non-economic working condition, it should not be placed in continuous overload work for a long time.
The reliable structure of SH15 amorphous alloy transformer
⑴Solid insulated encapsulated winding of SH15 amorphous alloy transformer
⑵Unencapsulated winding of SH15 amorphous alloy transformer, the higher voltage is the high voltage winding and the lower voltage is the low voltage winding.
From the relative orientation of high and low voltage windings, the high voltage can be divided into concentric and overlapping. The concentric winding is simple and convenient to make.
Overlap type, mainly used for SH15 amorphous alloy transformer.
2. Structural features of SH15 amorphous alloy transformer
1. SH15 amorphous alloy transformer has safety, fire prevention, no pollution that can work directly at the load base;
2. SH15 amorphous alloy transformer select domestic advanced technology, high mechanical strength, strong resistance to short circuit, some small discharge, good thermal stability, high reliability, long service life;
3.SH15 amorphous alloy transformer has low loss, low noise, significant energy saving effect, maintenance-free.
4. SH15 amorphous alloy transformer has good heat dissipation function, the overload can be strong, and the capacity can be improved when the air cooling is forced;
5. Good moisture-proof function that used to work in high humidity and other harsh environments.
6. SH15 amorphous alloy transformer can be equipped with a complete temperature viewing and maintenance system. The intelligent signal temperature control system is selected which can actively view and patrol the respective operating temperatures of the three-phase windings that can actively start and stop the fan, and have alarm, trip and other functional settings.
7.SH15 amorphous alloy transformer has small size, light weight, small footprint, low equipment cost.
Iron core of SH15 amorphous alloy transformer
SH15 amorphous alloy transformer choose excellent cold-rolled grain-oriented silicon steel sheet, iron core silicon steel sheet uses 45 degree full oblique joint, so that the magnetic flux passes along the direction of the silicon steel sheet joint.
⑵Pouring epoxy resin and quartz sand;
⑶ glass fiber reinforced epoxy resin casting (i.e. thin insulation structure);
⑷Multi-strand glass-fiber-impregnated epoxy resin surround type (usually choose 3 more because it can effectively avoid cracking of the cast resin and improve the reliability of the equipment).
