介绍了智能真空开关中触头温升、灭弧室的真空度、开关运动特性、一次回路参数等典型参数在线检测的实现。针对目前常见的固封式真空开关

提出一种电桥温升测量法;通过安置在固封绝缘筒外的电场探头检测屏蔽罩附近的电场变化信号

实现真空度的在线监测;通过与灭弧室动导电杆相连的位移传感器

得到操动系统的实时运动状态;采用基于Rogowski线圈/小电感互感器（LPCT）作为传感单元的电子式电流互感器和基于阻抗式精密分压器作为传感单元的电子式电压互感器实现一次回路电参数的测量。同时探讨了智能真空开关中传感器的植入和设计技术。

Abstract

Intelligent vacuum circuit breakers suitable for smart grid

including the monitoring function and system structure were introduced in this paper.Online measurement technologies of the key parameters including contactor temperature

pressure in vacuum interrupters

mechanical parameters

and voltage and current of main circuit were introduced in details.A contact temperature measurement method based on four arm electrical bridge was presented for the expoxy insulator VCB.A spy was used to detect the electric field of shielding case

which can reflect the vacuum pressure in the interrupter.The linear or angular displacement sensor was used to detect the real-time operation parameters.ECT/EVT was used to detect the voltage and current of main circuit.Combination and design of vacuum circuit breaker and the sensors was discussed too.
