摘要
本文结合Intel 80C 196MC单片机的高速控制性能,讲述了一种以此单片机为控制核心、晶闸管为主电路元件的软起动系统。实现三相异步电动机的平稳软起动,降低了起动电流。并对电机的过流、欠压等进行故障保护。既延长了电机寿命,又减轻了对电网的冲击。
This paper introduces a soft start system based on the Intel 80C196MC and thyristor. This system makes the motor start steadily, it can limit the starting current, protect the motor well against overcurrent and low-voltage, prolong the motor life and reduce the impact on the electric network.
