摘　　要：阐述了关于多腔避雷器以及具有绝缘子和避雷器两者性能的新型避雷器的一系列研究进展和实际野外运行经验。得出结论:MCS系统主要用于保证雷电过电压冲击放电后的灭弧动作能够顺利完成;MCS系统为开发简单高效的避雷器提供了可能;作者成功开发出了多腔绝缘子避雷器,该避雷器将MCS安装在绝缘子圆盘周围,且没有对绝缘子性能造成任何折损。运用这些新型设备保护6~40.5 kV的架空线,可在不使用避雷线的情况下防御感应过电压和直击雷的侵袭。在过去6年的实际运行经验中,MCS展现了其高效性和可靠性。This paper represents the results of research, development and field experience of multi- chamber arresters and insulators that combine characteristics of insulators and arresters. The main results are as follows： MCSs have been developed to ensure Arc extinguishing action completed successfully after a lightning overvohage impulse; MCSs make it possible to develop simple, and efficient arresters （MCA） ; Multi-chamber insulator-arrester have been developed, comprising production insulators and MCSs that are mounted over the perimeter of the insulating body without adversely affecting the insulating properties of insulators..Application of these devices allows to protect overhead transmission lines rated at 6 to 40,5 kV and above from induced overvoltage and direct lightning strokes without usage of shielding wire. Over past 6 years, MCS have shown its efficiency and reliability.
