摘 要：随着电力系统对智能化和可靠性要求的不断提高，变电站内隔离开关仅有的电机热偶保护已经无法应对实际错综复杂的各种故障类型以及满足电力系统发展需求。结合隔离开关常见故障以及实际检修工作需求，提出一种AIS(空气绝缘开关设备)隔离开关智能在线监测和状态评估系统方案，给出了系统的整体架构、功能，并对其技术路线进行了分析，该系统可实现隔离开关的故障在线监测和运行状态评估，为提高隔离开关的变电检修和消缺效率提供了一种新的思路和方案。

Abstract: With the continuous improvement of the requirements for intelligence and reliability of power systems, the only motor thermocouple protection of isolation switch in substationis unable to deal with the actual complex fault types and meet the needs of power system development. Combined with the common faults of the isolation switch and the actual maintenance requirements, AIS (air insulated switchgear) isolation switch intelligent on-line monitoring and condition evaluation system project are proposed, and the whole structure and function of the system are given, and its technical route is analyzed. Finally, the system can realize the on-line fault monitoring and running condition evaluation of the isolation switch, and provides a new idea and scheme for improving the efficiency of the maintenance and elimination of the isolation switch.
Key words: air insulated switchgear; isolation switch; intelligent on-line monitoring; artificial intelligence; failure prediction
