10、者配合使用才能做到控制灵活、保护齐备。16、热继电器能否作短路保护？为什么？答:热继电器不能作短路保护。因为热继电器主双金属片受热膨胀的热惯性及操作机构传递信号的惰性原因,使热继电器从过载开始到触头动作需要一定的时间,也就就是说,即使电动机严重过载甚至短路,热继电器也不会瞬时动作,因此热继电器不能用作短路保护。17、直流调速系统如下图所示,试分析就是何种调速系统？有哪些反馈？并分析当负载增加后,系统的调整过程。(四道题目,图分别就是P309 图 11、9 的速度负反馈、P312 图 11、10的电压负反馈、P313 图 11、11 的电压负反馈与电流正反馈系统、P315 图 11、13 电流截

11、止负反馈)。调整过程可参考下面电压负反馈调速系统的形式:18、在变压变频的交流调速系统中,给定积分器的作用就是什么？答:给定积分器就是一个具有限幅的积分环节,它将给定的正、负阶跃信号转换成正、负斜坡信号。正斜坡信号使启动过程变得平稳,实现软启动;负斜坡信号使停车过程变得平稳。五、计算题1.有 一 直 流 电 动 机 脉 宽 调 速 系 统(PWM-M),若 外 加 电 源 电 压U(E)=100V,脉 冲 频 率f=4000HZ,在脉冲周期内全导通时的理想空载转速n01=1000r/min,如要求电动机的理想空载转速 n02=400r/min,问:此系统在一脉冲周期内的导通时间(脉冲宽度)T1
