摘要
文章综述了用于中压开关柜监测、测量的两大类传感器:电流和电压测量保护用传感器;非电量数值传感器。新型的电流和电压传感器优越性明显,在解决了细节及接口问题后,将逐渐安装使用。非电量数值传感器技术是将开关柜“定期”维护转变为“按状态”维护的关键技术,有很好的应用前景。
The paper introduced two category of sensors: such as current & voltage measurement and protection sensor, as well as non-electric numerical value sensor, which are used for supervisory and measurement in intelligent M.V Switchgear. New current and voltage sensor have apparent advantages, which can be used gradually after solving detail problem and interface. Non-electric numerical value sensor is key technology transforming 'Timing' maintenance of switchgear into 'on condition' maintenance of Switchgear, which have bright prospect in application.
