| 独立式探测器以结构区分，可以分为： Independent detectors can be divided into: ⑴外置互感器式探测器 (1) external transformer detector 剩余电流互感器与探测器本体分离，互感器通过一段信号线与探测器连接。 The residual current transformer is separated from the detector body, and the transformer is connected with the detector through a signal line. 这种方式为安装提供了很好的灵活性，只要配用不同窗口尺寸的互感器，就可以使用在各种电流等级的线路上。互感器与探测器本体可以相距数米至数十米。但这种方式对互感器及信号线的要求较高。 This method provides a good flexibility for installation. As long as the transformer with different window sizes can be used, it can be used on various current level circuits. Mutual inductor and detector body can be several meters to tens of meters apart. But this method has higher requirements for mutual inductor and signal line. ⑵内置断路器式探测器 (2) built-in circuit breaker detector 把断路器、剩余电流互感器集成在探测器内，类似于RCBO。 The circuit breaker and residual current transformer are integrated into the detector, which is similar to RCBO. 这种方式使安装变得很方便，只须接进线和出线。由于厂家整体装配，用户无须顾虑周围电磁环境的干扰。有些型号还内置了电动操作机构，具备自动或遥控分闸和合闸的能力，特别在无人值守的场所，能有效地提高设备运行率。这种探测器一般都具有不同程度的扩展功能。由于内部结构较复杂，因而对零部件的可靠性要求较高。而且内置断路器的电流容量是固定的，因此只能运行在最大正常工作电流不大于断路器额定电流的线路上。 This method makes the installation convenient, and only needs to take in the line and outlet. Due to the overall assembly of the manufacturer, users need not worry about the interference of the surrounding electromagnetic environment. Some models also have built-in electric operating mechanism, which have the ability of automatic or remote control and closing, especially in unattended places, which can effectively improve the operation rate of the equipment. Such detectors generally have different degrees of expansion. Because the internal structure is more complex, the reliability of parts is higher. Moreover, the current capacity of the internal circuit breaker is fixed, so it can only operate on the circuit with the maximum normal working current not greater than the rated current of the circuit breaker. |
