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.
