摘要
综述了用于中压开关柜监视、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。
summarize the two type's sensor of medium voltage switchgear surveillance and measuring;the protective sensor of measuring current and voltage;un-coulometer numerical values sensor,after solve a problem about details and connect,the new type current and voltage sensor has a clearly advantage,and have been used little by little,it is the key to the technical that un-coulometer numerical values sensor will replace'status'defend as'regular'defend,and has a bright future.
