三相异步电动机的反接制动,控制电路图如下:(,电动机反接制动电路)从上图可看出,其主电路和正反转电路类似。不同的是,由于反接制动时,旋转磁场的相对速度较高,差不多为启动时的两倍,定子电流也很大,在反接制动电路中增加了限流电阻R。速度继电器的触头ks串接在控制电路中。电机反接制动过程分析:当电动机转速升高后,速度继电器的动合触点KS闭合,为反接制动接触器KM2接通做准备。停车时,按下复合按钮SB1(其动断触点断开,动合触点闭合),接触器KM1断电释放,动断辅助触点KM1闭合,接触器KM2线圈得电,KM2主触点闭合(同时KM2自锁触点闭合自锁,动断触点KM2断开,对KM1联锁),电动机反接制动。

???? In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 8.7/15 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status. This company produces the type refractory power cables for rated voltage 0.6/1 kv copper core cable, can also produce low smoke zero halogen fire-resistant power cable, high flame retardant fire-resistant power cable oxygen insulation layer, the fire-resistant performance in line with the GB/T12666.6 cable fire resistance test. Therefore, the overall performance of refractory series power cables is good and reliable. The water resistance performance of fireproof cable conforms to iec 502-2.

主要技术参数:环境温度:-40℃~+65℃大气压力:70~106KPa相对温度:≤95%任意两端及任一端子与接地之间的绝缘电阻>5×104ΜΩ。任意两端及任一端子与接地之间在接通1000V交流时,1min应无击穿或飞弧现象。
最高传输频率分别为30MHz与100MHz。本产品适用于市内、近郊和局部地区的通信线路。导电芯线采用标称直径为0.4、0.5、0.6、0.7、0.8、0.9mm的软铜线。绝缘单线绞合成对后采用心式(10对、20对)或单位式(30对及以上)绞合成缆芯,每个基本单位的子单位扎带颜色相同,各基本单位扎带颜色按全色谱要求排列。
在单片机软硬件应用电路中,如果要实现独立的按键输入,在不使用其他的功能辅助IC的情况下,一般一个按键对应一个IO引脚,如果要实现多个独立按键输入,那么就要多个独立IO。如下图所示,普通IO实现的独立按键输入然而,在实际应用的很多场合下,我们往往会碰到单片机IO引脚不够用,或者,需要出于成本等原因,我们不能更换其他多IO的单片机。我们需要实现一个IO实现多个独立按键输入,下图所示的这种方法就是利用单片一个带ADC转换的IO实现多个按键输入检测。
