摘要
分析了控制回路过长对接触器可靠吸合和可靠释放的影响。结合接触器厂家资料,计算了1.5mm^(2)控制电缆的最大允许长度。根据工程实践总结了一些解决方案,以期为电气设计人员提供参考。
The influence of long control loop on the reliable close and release of contactor is analyzed. Combined with the data of contactor manufacturer, the maximum allowable length of 1.5 mm^(2) control cable is calculated. Some solutions are summarized according to engineering practice, it can provide references for electrical designers.
