产品特点Product Features

一二次融合成套断路器由开关本体、馈线终端、电源电压互感器、传感器、连接电缆等构成。开关本体、馈线终端、电源电压互感器之间采用军品级航空接插件，通过户外型全绝缘电缆链接，接口定义符合国网标准。

开关本体内置电流互感器（A\B\C\0）和零序电压传感器，提供Ia、Ib、Ic、I0（保护及测量合一）电流信号和零序电压U0。

馈线终端具备单相接地、相间短路故障处理功能，具备配电自动化三遥功能，具备故障录波功能。实现“配网自动化”的理想开关设备，具备分、合负荷电流，过载电流及短路电流之能力。

This circuit breaker is consisted of main body of switch, feeder terminal, power supply voltage transformer, sensor, connecting wires. The mainbody of switch, feeder terminal, power supply voltage transformer adopts Military level aviation connectors, connected by outdoor type fully insulated cables, the connectors meet the requirements of national standards.

The current transformer(A/B/C/O) and zero sequence voltage sensor inside the switch mainbody, supply Ia，Ib，Ic,I0(protection and measurement, current signal and zero sequence voltage U0.

The feeder terminals have the functions of single phase to earth, short circuit fault between phases, also it has the functions of distribution automation three remote control and fault recording. It is a ideal switch device which realizes “distribution automation” and has the capacity of opening&closing the load current, overload current and short circuit current.
