TWO Medium voltage/high voltage frequency converter / inverter / vfd
it is used for the speed-adjusting control of AC motors with power supply of 3kv / 6KV or 10KV and motor power of 200-5000KW.Frequency converter uses the technology of vector control, and it realizes high-torque, high-precision and wide range of speed-adjusting drive. It has the function of energy feedback to power grid, the energy-saving effect is significant. Uses color LCD touch screen to display, it is convenient and simple to be installed and debugged, at the same time it can print and output report reform about running statements and make remote control. The frequency converter has advantage of high input power factor, less current harmonic and it doesn't need power compensation and harmonic suppression devices. The power circuit is modularized and it is simple and rapid to maintain. The connection between high voltage main circuit and controller is optical fiber, so it is safe and reliable. It has the character of low-speed output and high torque, strong capability of overload, complete protective function, high reliability and so on. Particularly, Working condition requirementsit is suitable for working condition requirements of hoister at colliery.
