A test system for an alternator

Abstract

The invention discloses an AC power generator testing system, which comprises a control computer, a test and control unit, a prime mover unit, transfer tooling, a power converter, and a cooling and heating system, wherein the prime mover unit comprises a drive motor and a driver; the transfer tooling is connected with a to-be-tested sheet; the to-be-tested sheet is an AC power generator; the drive motor is a high-speed driving drive motor; the drive motor provides operation power for the to-be-tested sheet; the transfer tooling is used for simulating an accessory gearbox; the control computer controls the high-speed driving drive motor to operate; the test and control unit is used for carrying out verification and acceptance on the to-be-tested sheet performance test and participating a joint test; and the test and control unit carries out data acquisition and control on the to-be-tested sheet and the power converter and realizing monitoring and controlling on the drive motor. According to the AC power generator testing system, related parameters of the power generator in different working states can be automatically measured in real time, and evidences are provided for product development, performance checking and inspection and acceptance.

Description

technical field [0001] The invention relates to the technical field of alternator testing, in particular to an alternator testing system. Background technique [0002] The aero-engine numerical control system (FADEC, full-authority digital electronic engine control mechanism in which the alternator includes supporting power conversion) is an important component of the aero-engine numerical control system and the main power supply of the system. The safety and reliability of the alternator, It directly affects the safety and reliability of the entire engine numerical control system, and high efficiency, longevity and high reliability are the inevitable requirements for its development. In order to improve design efficiency, effectively avoid design repetitions due to lack of experience, and ensure project schedule requirements, it is necessary to verify the design scheme while designing, and make a fast and reliable evaluation. [0003] In the design process of aviation alte...

AI Technical Summary

Problems solved by technology

[0004] The test and acceptance platform of the alternator in the existing aero-engine numerical control system adopts the traditional gear-up gearbox method, which has a large moment of inertia and slow response speed, and cannot truly reproduce the transient change process of the engine.

Unable to meet the testing and acceptance requirements of high-power and high-speed generators

[0005] Due to the lack of special testing and testing equipment, the lack of detection and testing methods after the product enters the factory, and the lack of depth of test verification, it has always affected the smooth progress of the development of the entire engine numerical control system.

The technology related to the development of generators, especially the test and testing technology of key components of generators, is a technology strictly blocked by foreign countries, and there is no similar equipment in China for reference.
