摘要
传统的电缆护层绝缘监测方法存在一定的问题,已明显地不能适用于高压电缆线路。研究分析了高压电缆线路护层循环电流与护层绝缘状况之间的关系,提出了电缆护层绝缘状况的判据,介绍了在此研究基础上研制的一套护层绝缘监测系统的构成和主要功能。经厦门电业局应用的实践表明,该系统能够满足实际应用的要求。
The traditional insulation monitoring methods of the cable sheath have certain default, cannot suit for HV cable circuit obviously. This paper researches and analyzes the relationship between the circulative current and insulation status of the HV cable sheath, presents the criterion to judge the insulation status of the cable sheath, introduces the components and main functions of a sheath insulation monitoring system developped on this research base. The application of this system in Xiamen Electric Power Company has proven that it could comply with the requirements of the practical application.
