Combiner of OEMU-JH8 electronic transformer
一、概述(Description)
OEMU-JH8合并器是數(shù)字式光電電流電壓互感器的合并單元。本產(chǎn)品可以分為三種型號(hào)：A、66kV及以上光電型電子式互感器用合并器；B、35kV及以下電子式互感器用合并器；C、35kV及以下的電磁式互感器用合并器。合并器除了可以接收并處理來自多個(gè)采集器的數(shù)字信號(hào)外，還可以接收并處理電磁式互感器提供的電壓、電流模擬量。合并器提供同步信號(hào)輸入通道，可以接收電站同步信號(hào)以同步連接的各采集器。
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.
合并器還可以通過輔助CPU和擴(kuò)展入開出直接提供保護(hù)、測量等功能，同時(shí)通過光纖以太網(wǎng)接口給監(jiān)控、測量等裝置提供數(shù)據(jù)。
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.

2、合并器主要結(jié)構(gòu)(Main structure of combiner)
本裝置由以下模件構(gòu)成：電源模件(POWER)，數(shù)據(jù)處理模件(CPU)，母板模件(MOTHER)，交流變換模件(AC)，激光電源模件(LASER)，面板模件(PANEL)。
The device consists of the following modules: power module (POWER)，data processing module (CPU), mother board module (MOTHER)，alternate current conversion module (AC), laser power module (LASER) and panel module (PANEL).
合并器主要用于接收采集器的數(shù)字信號(hào)以及來自電磁式互感器的模擬信號(hào)，對這些信號(hào)合并理后以光信號(hào)方式對外提供數(shù)據(jù)。本模件主要提供以下五種功能(The combiner is mainly used to receive the digital signal of the collectors and the analog signals from electromagnetic transformer and provides data in the form of optical signal after they are aggregated and treated. The module mainly provides the following five functions)：
(a) 接收并處理多達(dá)9路的采集器模件傳來的數(shù)據(jù)。合并器的A/D采樣部分，可以采樣交流變換模件輸出的最大18路的模擬信號(hào)。(Receive and treat data sent by the collectors from more than 9 channels, the sampling part of A/D of combiner; sample and exchange and convert the analog signal output from maximum 18 channels by the modules.)
(b) 接收站端同步信號(hào)，同步各路A/D采樣，并且將采集器的同步信號(hào)輸出到激光電源模件。(Receive the synchronous signal of station terminal, make the A/D sampling from various channels synchronous and output the synchronous signal of collector to laser power module.)
