| 摘 要： | 针对舰船消磁系统电源和负载特殊性,建立了消磁电缆的电路模型,根据该模型提出消磁电缆绝缘的测量方法并推导出绝缘测量公式。该测量原理不但能够对绝缘电阻进行准确测量,而且能实现电缆单点绝缘故障时故障点定位。由于消磁直流电源的电压幅值不断变化,文章在最后给出了电压变化条件下绝缘测量的补偿方法。

| Abstract: | The source and load of ship’s degaussing system is different from normal DC power system.To monitor degaussing system insulation,it is necessary to set up a new circuit model of degassing cable.The paper gives a circuit model and derived formula of insulation measurement,which can not only calculate the value of insulation resistance,but also locate fault point.Considering the voltage changes of degaussing source,a method to compensate changing voltage is presented. |

| Keywords: | degaussing system insulation measurement cable model fault location voltage compensation |
