交流控制回路中不容忽视的电缆电容

Non-Negligible Capacitance of Cables in AC Control Circuit

近年来,在海洋石油陆上终端、海上平台及大型船舶的配电系统设计中,常会遇到MCC远离现场控制操作的情况,届时必须考虑控制电缆间电容对交流控制回路的影响。对这一问题进行了分析论述,以期引起设计人员对这一问题的重视。

It is often happened at offshore platform, onshore terminal station or FPSO that local push - button is located far away from MCC. In such case, the capacitance around control circuits should not be negligible. And electrical engineers must pay attention to the influence of capacitance between cables in AC control circuit. Such problems are discussed in this paper is order to give attentions to the designers.
