Abstract

The invention discloses a novel frequency converter. The frequency converter comprises a pedestal, a fan installing plate, a support plate, an upper cover, a capacitor plate, a cooling fan, a radiator, a driving plate, a control panel and an IGBT module. An end portion of the pedestal is fixedly provided with the fan installing plate. The fan installing plate is provided with the cooling fan. An inner bottom portion of the pedestal is fixedly provided with the radiator. The radiator is connected to the cooling fan. An upper portion of the radiator is provided with the support plate. The support plate is fixedly provided with the capacitor plate, the IGBT module and the driving plate. The capacitor plate is connected to the driving plate in a signal connection mode. The IGBT module is connected to the driving plate in the signal connection mode and is arranged above the radiator. The upper cover is arranged above the support plate. Two side portions of the upper cover are fixedly connected to the pedestal. An inner side of the upper cover is fixedly provided with the control panel connected to the driving plate in the signal connection mode. The structure and performance of the frequency converter are optimized. An internal space is reasonably used so as to install an electrical component. Purposes of simplifying the structure, reducing the weight, carrying out installation conveniently and reducing cost are reached, and safety and reliability are increased.

Description

technical field [0001] The invention belongs to the technical field of industrial control electrical equipment, and in particular relates to a novel frequency converter, which improves the structure of the existing frequency converter and reduces the production cost. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The inverter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter also...
