33kV11kV dry-type transformer
Features of Products
33kV class Dry-type transformers are widely used in locallighting, high-rise buildings, airports, wharf CNC machinery and other places.
Simply speaking, dry-type transformers refer to transformers in which iron cores and windings are notimmersed in insulating
oil.
Cooling methods are divided into natural air cooling (AN) and forced air cooling(AF). During natural air cooling.
the transformer can operate continuously for a long time at rated capacity. When forced air cooling occurs, the output capacity of the transformer can be increased by 50%.
Suitable for intermittent overload operation or emergency overload operation; Since the load loss and impedance voltage increase greatly during overload and are in non-economic operation.
it should not be kept in continuous overload operation for a long time.

Sc(B)10 Series 11kv Class Dry Type Transformer Technical Data
ZT(P)S series phase-shifting rectifier transformer
Product Description
The converter transformer for variable frequency speed regulation is the power supply part of the high-voltage frequency converter. It plays the role of isolation, phase shifting and multiplexing. It is one of the core components of the high-voltage frequency converter. According to the cooling method, it is divided into dry type and oil-immersed type. kind.
The insulation grade of the dry-type converter transformer for variable frequency speed regulation produced by our company is Class H. The new insulation structure and advanced technology are used in the structural and electrical design to improve the short-circuit resistance and electrical strength, making the performance more reliable. During the design process, the impact of harmonics generated by rectifier components on the transformer windings and core is fully considered. Sufficient margin is provided to enable the windings and core to withstand the additional temperature rise caused by harmonics and maintain low noise, ensuring the reliability of the transformer. service life.
The winding temperature rise caused by harmonics is fully considered during design and manufacturing, which effectively ensures the service life of the transformer; VPI (vacuum pressure) impregnated paint and cured at high temperature have good moisture-proof, dust-proof, and anti-pollution effects, ensuring the reliability of the transformer. .
The materials selected undergo strict quality inspection, and all raw material manufacturers are strictly reviewed in accordance with ISO9001. The product has the characteristics of high reliability and is widely used with 6-pulse, 12-pulse, 18-pulse and multi-pulse frequency converters. According to the types of inverters and rectifiers and user requirements, special design and manufacturing plans are formulated.
