详细分析了交流接触器在不同使用条件下的闭合与分断时触点两端电压与回路电流情况，并研究了AC1～AC4工作制下的控制时序。
The conditions of voltage between contactors and current in main circuit under different using types are analyzed in detail, then designed the control sequences with working mode AC1-AC4.
转动点火钥匙，弹簧的压力使“开启”位置变为“启动”位置，起动接触器闭合，使得起动电机线圈或磁性开关与电池接通。
When the ignition key is turned against spring pressure past the on position to start, the starting contacts close. This connects the cranking-motor solenoid or magnetic switch to the Battery.
双电磁系统控制电路确保两台并联接触器的同步闭合和无声节电运行。
Its control circuit with double electromagnetic system can ensure synchronous closing, silent and energy saving operation of two contactors in parallel.
当达到额定转速后，控制系统需要一个无压降连接(压缩机运行)，在这种状态下接触器必须闭合。
After reaching the rated speed, a potential-free contact (compressor running) is required for control system. The contact must be closed in this state.
电路设计还避免了接触器触点带电闭合。
Also, charged contact problem with the contactor is relieved.
其余的接触器将基于距离控制接触器的闭合或断开的时间补偿进行闭合或断开。
The remainder of the contactors will make or break based on an offset in time from the making or breaking of the control contactor.
