WESDAC D20ME GE gas turbine control I/O module
WESDAC D20ME GE gas turbine control I/O module
A frequency converter is an electrical energy control device that utilizes the on-off effect of power semiconductor devices to convert a power frequency power supply to another frequency. It can achieve soft starting, variable frequency speed regulation, improve operating accuracy, change power factor, overcurrent/overvoltage/overload protection, and other functions for AC asynchronous motors.
Mainly used in the application of fans and water pumps. In order to ensure the reliability of production, various production machinery has a certain margin when designing and using power drives. When the motor cannot operate at full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in waste of electrical energy. The traditional speed regulation method for fans, pumps, and other equipment is to adjust the air and water supply volume by adjusting the opening of the inlet or outlet baffles and valves. Its input power is large, and a large amount of energy is consumed during the interception process of the baffles and valves. When using variable frequency speed regulation, if the flow requirement is reduced, the requirement can be met by reducing the speed of the pump or fan. Below are the basic methods for debugging general frequency converters.
