 OEMU-JH8电子式互感器的合并器
Combiner of OEMU-JH8 electronic transformer
一、概述(Description)
OEMU-JH8合并器是数字式光电电流电压互感器的合并单元。本产品可以分为三种型号:A、66kV及以上光电型电子式互感器用合并器;B、35kV及以下电子式互感器用合并器;C、35kV及以下的电磁式互感器用合并器。合并器除了可以接收并处理来自多个采集器的数字信号外,还可以接收并处理电磁式互感器提供的电压、电流模拟量。合并器提供同步信号输入通道,可以接收电站同步信号以同步连接的各采集器。
OEMU-JH8 combiner is the incorporated unit of digital photoelectric current and voltage transformer. The product can be divided into three types:A、The combiner that is used in the photoelectric transformer and rated voltage above 66kV;B、The combiner that is used in the electronic transformer and rated voltage below 35kV;C、The combiner that is used in the electromagnetic transformer and rated voltage below 35kV.The combiner can not only receive and handle the digital signal from many collectors but also the analog variable of current and voltage provided by the electromagnetic transformer. The combiner provides the input channel of synchronous signal and receives the synchronous signal from the power station and all collectors that are connected synchronously.
合并器还可以通过辅助CPU和扩展入开出直接提供保护、测量等功能,同时通过光纤以太网接口给监控、测量等装置提供数据。
The combiner can provide the direct protection function and measurement through the auxiliary CPU and expansion and provide data to monitoring and measuring device through the optical fiber and the Ethernet interface at the same time.
