A full-load aging test equipment for inverters with three motor pairs

Abstract

The invention discloses a three-motor-combined frequency converter full-load aging test device. The three-motor-combined frequency converter full-load aging test device comprises an incoming wire breaker, an energy feedback unit, an industrial computer, tested frequency converters, first tested motors, second tested motors, test-accompanying electric generators and test-accompanying frequency converters. The incoming wire breaker is electrically connected with a mains supply. The incoming wire breaker is electrically connected with the tested frequency converters and the energy feedback unit respectively. The tested frequency converters are electrically connected with the corresponding first tested motors and the corresponding second tested motors respectively. The first tested motors and the second tested motors are connected in the axial direction. The second tested motors are connected with the test-accompanying electric generators in the axial direction. The test-accompanying electric generators are electrically connected with the test-accompanying frequency converters. The test-accompanying frequency converters are electrically connected with the energy feedback unit. The tested frequency converters and the test-accompanying frequency converters are electrically connected with the industrial computer. Since the three-motor-combined frequency converter full-load aging test device is equipped with the motors in different combinations, the three-motor-combined frequency converter full-load aging test device can be used for testing frequency converters at various power sections, thereby saving cost; the device conducts feedback to a power grid through the energy feedback unit, thereby lowering energy consumption.

Description

technical field [0001] The invention relates to a frequency converter aging test device, in particular to a full-load aging test device for a frequency converter with three motor pairs bound and capable of multi-station testing. Background technique [0002] On February 4, 2009, the State Council reviewed and approved in principle the adjustment and revitalization plan for the equipment manufacturing industry. Premier Wen Jiabao also specifically proposed in the government work report to implement the domestic relying project and government procurement system for independent research and development of major equipment, focus on the development of major complete sets of equipment, high-tech equipment and equipment required by high-tech industries, and improve the integrated innovation and localization of the equipment manufacturing industry. Level. During the "Twelfth Five-Year Plan" period, the country formulated a systematic strategy and plan for the development of the equ...
