融辉荣4821继电器2 - m4x10底座内部接线图 底座是怎么接的 -
梁炎孟13646055429 ______ 如图所示: 继电器一般都有能反映一定输入变量(如电流、电压、功率、阻抗、频率、温度、压力、速度、光等)的感应机构(输入部分); 有能对被控电路实现“通”、“断”控制的执行机构(输出部分);在继电器的输入部分和输出部分...

融辉荣4821我刚学电工请告诉我这张图的原理,刚学看不懂,为什么是这样接 -
梁炎孟13646055429 ______ 你的交流接触器是220v的,A1是接的零线,上面的A2是控制线也就是启动线,下面的A2是接的回路线也就是停止线,当启动按钮按下时交流接触器通电后就会自吸,当停止按钮按下时交流接触器就会弹出.因为下面的A2本身就是带电的,当启动按钮按下时上面的线圈通电就自吸,自吸后停止按钮是带电的,所以你不按停止按钮电一直是通的,当你按钮下停止按钮是电就断开了.

融辉荣4821这个中间继电器接线图能不能实现缺相自保??? -
梁炎孟13646055429 ______ 朋友,可以啊,原理是按sb2---A相电经过sb1--sb2--ka吸和线圈--B相,常开触电ka自锁,然后B相经过常开触电KA到km吸和线圈--fr热继电器,最后到C相,主触头KM吸和,电机工作. 当其中某一相电缺相了两个吸和线圈都会断电主触头就会分断,从而保护电动机.

融辉荣48215个小型继电器,5个接近开关控制2个气缸怎么接线, -
梁炎孟13646055429 ______ 在整个系统断电状态下,气缸复位.闭合SB1自锁型按钮开关,给电路通电.就是一个开断电源的开关.闭合SB1,这时气缸出去的接近开关感应到,SQ1闭合.中间继电器ka1线圈得电.ka1,常开点ka1闭合,形成自锁回路.ka1闭合电磁阀yv1得电.气缸出.当到达sq2接近开关处.sq2闭合,ka2继电器线圈得电.ka2常开点闭合,常闭点断开.ka1线圈失电.ka1常开点断开.电磁阀失电,气缸退回.当气缸回到原位sq1接近开关处.又重复动作.在这个电路图中没有画接近开关的电源.在图中如果接线嫌麻烦.可以把ka2的自锁回路去掉.ka2主要作用就是让ka1失电.气缸退回.

融辉荣4821下图为继电器自锁电路,右边那个闭合的kt5 - 8是什么意思 是继电器常闭触电吗???? -
梁炎孟13646055429 ______ 1-3是常开5-8 是长闭2-7线圈

融辉荣4821接触器自锁反转控制线路电气接线图怎么画 -
梁炎孟13646055429 ______ 接触器自锁反转控制线路电气接线图: 带电气互锁的正反转控制电路 将接触器KM1的辅助常闭触点串入KM2的线圈回路中,从而保证在KM1线圈通电时KM2线圈回路总是断开的;将接触器KM2的辅助常闭触点串入KM1的线圈回路中,从而保...

融辉荣4821一个三联行程开关控制三点(左、中、右),两个中间继电器、三个按钮开关控制两个中间继电器;求接线图.
梁炎孟13646055429 ______ 哦,先利用1和2继电器上的辅助触点分别把二个按键进行互锁,即相互的按键线都经过对方的常闭触点.再把二个继电器的线圈供电电源的别一头全通过SB3的常闭触点,线圈(电源)的另一头分别通过相对应的按键并再利用本继电器的一个常开触点来进行自锁即可.
