Frequency control of motor speed in converter transformer is part of high voltage inverter power supply, plays an isolation, phase shift and the effect of multiple, is one of the core components of high voltage frequency converter, according to the cooling mode can be divided into dry type, oil immersed type two kinds.
Our company produces frequency control of motor speed with dry-type transformer insulation class for class H. In the structure and the electrical design, it adopts new type insulation structure and advanced technology, enhancing strength, anti-short circuit ability, and is more reliable in performance. Fully considered in the design of rectifier components produced by the impact of harmonics of transformer winding and iron core, with enough margin for winding and iron core to handle additional temperature rise produced by harmonics, and maintain low noise, ensuring the service life of the transformer. Design and manufacture fully considering the temperature rise caused by harmonic winding, effectively ensuring the service life of the transformer. VPI (vacuum pressure varnished) and after high-temperature curing, it is moisture-proof, dust-proof, and has good prevention effects, guaranteeing the reliability of the transformer. Choose materials that all pass strict quality inspection; all raw material manufacturers are in accordance with ISO9001 strict censorship. The product has the characteristics of high reliability, a large number of pulse and pulse 6, 12, 18 pulse spread more pulse converter systems. According to the frequency converter, rectifier type, and user requirements, special formulation design and manufacturing solutions.
