三相电流互感器变比在线转换智能控制仪
On Line Conversion Intelligent Controller for Three-phase Current Transformer（CT）
三相电流互感器变比在线转换智能控制仪是太原山互科技有限公司与国网山西省电力公司太原供电公司共同研发的产品，主要用于供热采暖期与非采暖期等周期性开工企业用电计量，还用于风电和水电及光伏发电或用电双向计量等电能计量领域，其特点是发电或用电负荷差距很大而采用2～100倍复合变比的电流互感器。在大小负荷转换时，实现不停电即在线安全转换变比，确保计量准确防止漏计量现象发生。特别是在“煤改电”供热取暖项目中应用可以避免增加两套计量设备，节省用地空间，减少故障点和运维成本。
On Line Conversion Intelligent Controller for Three-phase Current Transformer is the Taiyuan Shanhu Technology Co., Ltd. and the Taiyuan Power Supply Company , Shanxi Electric Power Company, State Grid jointly developed patent products, patent number: ZL2017102195474; ZL2017203515329.Mainly used for heating period and non heating period, such as periodic power consumption measurement of enterprises, but also used in two-way measurement of electric energy metering field for wind power and hydropower and photovoltaic generating electricity or using electricity etc. Its characteristics is the big gap between electricity generation and electricity load, a current transformer with 2～100 times compound ratio is adopted, At the time of load conversion, realization of no power outages, that is, online security conversion ratio, ensure accurate measurement and prevent forgeting measurement. Especially in the "coal to electricity" heating project, the application can avoid increasing two sets of metering equipment, save space for land use, reduce the failure point and maintenance costs.
主要特征：
Main Features:
在线同步转换三相复合变比电流互感器（CT）变比时瞬间先接后断延时开路，有效防止二次开路危害的形成；
1、At the time when online synchronous conversion for the ratio of three-phase current transformer (CT) with compound ratio, connect first and then break that is delay open circuit, effectively prevent the formation of the hazards because of opening the secondary circuit;
实时采样监测计量二次回路电流，仪器默认手动模式和大负荷变比状态，可以切换到自动模式，既根据设定电流值，自动在线不停电同步转换三相电流互感器（CT）的变比；
2、Real time sampling and monitoring the current of the secondary circuit, the instrument, in the state of the defaul manual mode and big ratio, can switch to automatic mode is set according to the current value， automatic on-line synchronous conversion for the ratio of the three-phase current transformer (CT);
仪器内部设有电流潮流方向采样识别系统，可根据发电或用电双向计量的需要，将电压互感器（VT）二次回路接入仪器，籍此通过设定系统相位变化范围，实时判断母线潮流方向的变化，从而在线同步转换三相电流互感器（CT）的变比,来实现发电或用电的双向计量；
3、The instrument is arranged sampling identification systeminside for the flow direction of current , according to the need of bidirectional measurement for power generation or electricity , the secondary circuit of voltage transformer (VT) access the instrument loop, by doing so, by setting the phase change range of the system, real time to determine the direction with the change of flow current of power grid bus, automatic on-line synchronous conversion for the ratio of the three-phase current transformer (CT) to achieve two-way the measurement of generating electricity or using electricity;
仪器设有串行通讯接口RS232，可以实现与电能表通讯，也可以根据需要实现远端控制和无线通讯；
4、The instrument has a serial communication interface RS232, which can communicate with the electric meter, and remote control and wireless communication can be realized according to the requirement;
一台仪器可以同时控制三相四线制电能计量装置三台复合双变比电流互感器（CT），或者三相三线制电能计量装置两台复合双变比电流互感器（CT）的变比在线不停电转换；
6、One instrument can simultaneously control three sets of double ratio current transformer (CT) for three-phase four wire system electric energy metering device，or two sets of double ratio current transformer (CT) ratio for three-phase three wire system electric energy metering device whice ratio conversion on-line of power;
仪器安装位置推荐固定放置在电能表柜中电能表的下部，需要开孔露出仪器面板，这样后背布线简单、方便观察和操作。也可以放置在CT计量柜上部，需要留有观察窗门和布线通道；
6、Instrument installation position is recommended placed under the electric energy meter in electric meter cabinet, need to open a hole exposing the instrument panel, so the back wiring is simple, convenient observation and operation. It can also be placed upper part the CT metering cabinet, that is need to keep the observation window and the routing channel;
电源须从电源屏布线取电取保仪器不断电工作。
The power supply must be wired from the power screen to ensure the power supply of the instrument to work continuously.
