Integrally-moving high-voltage variable-frequency electric control device

2011 
The invention discloses an integrally-moving high-voltage variable-frequency electric control device, relating to a variable-frequency device. In the device, an exciting surge suppression cabinet, a transformer cabinet, a power cabinet and a control cabinet are arranged in a shell; a vacuum contactor and a current limiting resistor are arranged in the exciting surge suppression cabinet; a rectifying transformer is arranged in the transformer cabinet; a power unit for realizing variable-voltage and variable-frequency output is arranged in the power cabinet; a PLC (Programmable Logic Controller) unit is arranged in the control cabinet; the vacuum contactor and the current limiting resistor are connected with the rectifying transformer; the rectifying transformer is connected with the power unit; the power unit is connected with the PLC unit; the rectifying side of the power unit is used for performing controllable rectification by adopting an IGBT (Insulated Gate Bipolar Transistor) three-phase full bridge; a filtering and energy-storing electrolysis capacitor is connected in parallel in the middle; and an output side is provided with an H-bridge consisting of four IGBTs. The control device has the advantages of convenience and quickness for transporting and installing, and good energy-saving effect.
