摘要
国内电动机的运行损坏率较高,为此某电厂希望在它的大型异步电动机上装设新的保护装置,笔者从事了该装置的研制工作。新型装置是以8031为CPU的微机型装置,本文介绍该装置软硬件的设计思想和设计方法。实验室仿真实验表明该装置优于常规型保护装置(通常指机电式、整流式和晶体管式)。
For reasons of higher damage rate of domestic motor in service,a power plant desired to instal a new protective device on its large asynchronous motor.The author took Part in the development of the device.The device is a microprocessor-based protection device using 8031 as CPU.The design principle and method of its software and hardware are introduced.Simulation experiment has shown that the device is better than conventional protection device(e. g. electro-magnetic,rectifier and transistor types).
