    摘 要:針對三相XLPE 電纜接地磁感應電流極小的特點,提出了一種基于接地線電流法的多傳感器聯(lián)合監(jiān)測方法,闡述了該方法的實現(xiàn)原理,給出了電纜在線監(jiān)測裝置的具體實現(xiàn)途徑。仿真結(jié)果表明該方法可有效反映電纜的局部絕緣故障,且通過分析各監(jiān)測點接地電容電流還可確定局部故障所處位置,對于三相XLPE 電力電纜的絕緣監(jiān)測具有一定的參考價值。

    Abstract: Aiming at the character of three-phase cross linked polyethylene (XLPE) power cable that the grounding magnet induction current is very little, this paper raised a multi-sensor joint monitoring method based on grounding line current and described the realization principle of the method, giving the actual realization way of cable online monitoring device. Simulation analysis shows that this method can effectively reflect partial insulation fault of the cable. The local fault location was determined by analysis of every monitoring point grounding capacitance current, which provides certain reference value for the insulation monitoring of three-phase XLPE power cable.
                    Key words: three-phase cross linked polyethylene power cable; multi-sensor joint monitoring; grounding capacitance current; on-line monitoring device
