摘要
通过对接触器控制回路各元件电压相量图的分析,得出与接触器参数相关控制线路的最长可用距离计算公式,为现场操作箱长距离操作可行性提供分析判断依据;分析配电设计手册中最大长度估算公式的适用性。
Based on the analysis of the voltage phasor diagram of each component of the contactor control circuit,the formula for calculating the longest available distance of the control circuit related to the contactor parameters is obtained,providing an analysis and judgment basis for the feasibility of long⁃distance operation of the on⁃site operation box.The applicability of the maximum length estimation formula in the Power Distribution Design Manual is analyzed.
