Product Standards
In the recent years, with the rapid development of the power electronic technology, the high-voltage variable frequency speed adjustment technology has been widely used in the products, such as blower speed adjustment, and pump speed adjustment. The basic principle of the speed control by frequency variation is that: to change the power frequency alternating voltage into the direct current voltage by the rectifier bridge, then through the inverter the direct current voltage will be changed into the alternating current whose frequency and voltage are adjustable. And it will be used as the driving power supply of the alternating current motor and help the motor get the voltage and current which are needed for stepless speed regulation, a kind of high efficiency speed adjusting method without additional slip loss. AC motor speed adjusting drive is a new technology which develops rapidly in recent years in China, and variable frequency speed adjusting technology has been listed as one of the ten energy saving and comprehensive utilization technological transformation demonstration projects.
Manufacturing the phase-shifting rectifier transformers domestically is in urgent need for the mature development of variable frequency speed adjusting technology. Following the demands of market and based on the technology of leading product of non-encapsulated dry type transformer, our company successfully have researched and developed the multi-winding phase-shifting rectifier transformer which could be classified into several groups such as 9 secondary sides, 12 secondary sides, 15 secondary sides, 18secondary sides and 24secondary sides having carious shifted phases, according to transformer capacity.
