Motor variable-frequency driver aging test device and test method thereof

Abstract

The invention relates to a motor variable-frequency driver aging test device and a test method thereof. The device comprises a data acquisition unit, an aging power supply controller, and a data analysis and monitoring unit, wherein the data acquisition unit is used for acquiring various data of a variable-frequency driver during the aging test process, the aging power supply controller used for controlling a power supply supplied to the variable-frequency driver and a load, the data analysis and monitoring unit is used for reading data of the data acquisition unit and sending control commands to the aging power supply controller, the load is an electric reactor analogue load, dotted terminals of the electric reactor analogue load are mutually connected, and the rest three taps of the electric reactor analogue are connected to a three-phase output end of the variable-frequency driver. The motor variable-frequency driver aging test device replaces a motor with an electric reactor to be served as the load of the motor variable-frequency driver, since the electric reactor is an inductive load, and the resistive component is small and the reactance component is large, thus the actual absorbed active power is very small, and most of reactive power is exchanged repeatedly between the driver and the electric reactor without being consumed.

Description

technical field [0001] The invention relates to the technical field of motor driver aging testing, and relates to a motor variable frequency driver aging testing device and a testing method thereof. Background technique [0002] The traditional method of aging motor variable frequency drive, one method is no-load aging: the motor variable frequency drive works in a no-load state. The aging test is fully exposed; another method is on-load aging: the motor variable frequency drive works under the rated load state with the motor, which consumes a lot of energy and takes up a lot of space. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of no-load aging of existing motor variable frequency drives that cannot fully expose hidden dangers and on-load aging that consume a large amount of energy and occupy space, and provide a method that can not only eliminate circuit component defects, welding and assembly hidden dangers du...
