ABB接触器AX300-30-11-88*230V隔壁

显示的是电动机正反转控制接线图，而且是采用按钮加接触器辅助触电的双重互锁，带自保持的控制方式，控制回路电压为线电压。从原理上看是没有问题的，能够实现基本功能。但是我觉得热继电器的常闭接点一般都接在接触器线圈与电源“2”之间，这样做的目的是当热继电器动作以后其常闭接点断开，此时整个控制回路除了SB1的一端（“1”）以及热继电器常闭接点的一端（“2”）带电以外，其他元件都不带电，特别是接触器的线圈是不带电的，既有效的减少了人员因为检查动作原因而触电的危险又能使线圈彻底断电。因为通常热继电器动作都是由于主回路电流长时间过大，使得继电器内双金属片温度达到动作值后保护动作而切断主回路，达到保护电动机以及接触器的目的。

那就在远方再设置一套用来控制正反转的启动按钮与图中对应的SB1 SB2并联，停止按钮和SB3串联就行了。
