摘要
为解决电网设备出现绝缘老化故障问题,提出全生命周期下高压电缆户外终端绝缘老化状态自动监测方法。管理高压电缆户外终端设备的生命周期,在生产运营阶段,分析高压电缆户外终端绝缘老化状态温度损耗特性,构建终端绝缘老化评估模型,评估高压电缆户外终端的绝缘老化状态,设计老化状态监测标准,将评估的结果输入到监测标准中实现自动监测。实验结果表明,该方法能够有效分析老化状态下电缆户外终端设备在不同季节的电流泄露情况,分析不同使用年限设备的介质损耗,同时可以精准监测出多种类型的设备绝缘老化状态。
In order to solve the insulation aging problem of power grid equipment,an automatic monitoring method of insulation aging state of outdoor terminal of high voltage cable during the whole life cycle was proposed.The life cycle of high-voltage cable outdoor terminal equipment was managed.In the production and operation stage,the temperature loss characteristics of the insulation aging state of high-voltage cable outdoor terminal was analyzed,the terminal insulation aging evaluation model was constructed,the insulation aging state of high-voltage cable outdoor terminal was evaluated,the aging state monitoring standard was designed,and the evaluation results were input into the monitoring standard to achieve automatic monitoring.The experimental results showed that the method could effectively analyze the current leakage of outdoor cable terminal equipment in different seasons under the aging state,analyze the media loss of equipment in different service years,and accurately monitor the aging state of various types of equipment insulation.
