Motor variable frequency driver aging test device and test method thereof

Abstract

The invention discloses a motor variable frequency driver aging test device and method, and the device comprises a bottom plate, the bottom of the bottom plate is fixedly connected with supporting legs, the left side of the top of the bottom plate is fixedly connected with a box body, the left side of the front surface of the box body is fixedly provided with a control panel, and the right side of the front surface of the box body is fixedly provided with a display. A central processing unit is fixedly installed on the right side of an inner cavity of the box body, a communication module is fixedly installed on the left side of the central processing unit, and a transformer is fixedly connected to the bottom of the inner cavity of the box body. The motor variable-frequency driver aging test device has the advantage of being convenient to use, and solves the problems that when an existing motor variable-frequency driver aging test device carries out aging test on a motor variable-frequency driver, motor variable-frequency drivers of different sizes are inconvenient to clamp and fix, the load weight of a tested motor is adjusted, and the motor variable-frequency driver aging test device is inconvenient to use. And the aging condition detection of the motor variable frequency driver under different load conditions is influenced.

Description

technical field [0001] The invention relates to the technical field of motor variable frequency drives, in particular to a motor variable frequency drive aging test device and a testing method thereof. Background technique [0002] The variable frequency drive is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's operating power supply. The variable frequency drive 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, there are many variable frequency drives. protection functions, such as overcurrent, overvoltage, overload protection, etc., with the continuous improvement of industrial automation, variable frequency drives have also been widely used. The...
