Three-motor-combined frequency converter full-load aging test device

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 equipment, in particular to a full load aging test equipment for a three-motor paired frequency converter capable of performing multi-station testing. Background technique [0002] On February 4, 2009, the State Council reviewed and approved in principle the equipment manufacturing industry adjustment and revitalization plan. Premier Wen Jiabao also specifically pointed out in the government work report to implement the domestic support projects for independent research and development of major equipment and the government procurement system, focus on the development of major complete sets of equipment, high-tech equipment and equipment required for high-tech industries, and improve the integrated innovation and localization of the equipment manufacturing industry. Level. During the "Twelfth Five-Year" period, countries have formulated a systematic strategy and plan for the development of equipment ...
