宿秒梁941请教互锁电路! -
卓食琦13530445742 ______ 点动正反转接触器互锁控制 接触器KM1的常闭辅助触点(9,11)串联在接触器KM2的线圈回路,当接触器KM1工作吸合时,接点(9,11)断开,即使误操作按下按钮SB2,由于KM2的控制回路在(9,11)处是断开的,KM2的线圈也不能得电,...

宿秒梁941按钮与接触器互锁怎么接线? -
卓食琦13530445742 ______ 图不好传 还是给你描述一下吧 控制回路要先将分别控制正反转停止的两个按钮串联接好,随后将两个分别控制正反转启动的两个按钮并联接好后与停钮的一端接好,停钮的另一端准备与电源连接,然后再把分别正转反转主接触器的常开辅助接...

宿秒梁941三相电机正反转控制电路没看懂,谁能解释一下吗? -
卓食琦13530445742 ______ 主回路由KM1KM2构成.负责电机交换相序实现正反转. 按制回路中SB1控制KM1 KM1的辅助触点KM1实自锁(SB2,KM2相同) 串在KM1线圈中的KM2常闭触点,作用是互锁.以防止误操作使两继电器同时工作产生短路
