產(chǎn)品特點(diǎn)：三相集中計(jì)數(shù)，放電時(shí)間條形記錄，通訊，電子液晶顯示。DJs系列高靈敏避雷器放電記錄儀的工作原理及產(chǎn)品組成主要由采樣器、傳感器、轉(zhuǎn)接盒、顯示器、配套傳輸電纜及部分電子元器件組成。在正常工作電壓下，通過(guò)避雷器的泄漏電流變化通過(guò)采樣器及相關(guān)電纜傳輸至顯示器，并通過(guò)顯示器中的放大電路和a/D轉(zhuǎn)換電路轉(zhuǎn)換為數(shù)字信號(hào)，在顯示器中的微處理器控制下顯示。當(dāng)避雷器流過(guò)雷擊波、工作波或工頻過(guò)電壓時(shí)，強(qiáng)動(dòng)作電流從泄漏電流測(cè)量電路傳輸?shù)椒措娐?，泄漏電流測(cè)量電路受到保護(hù)。計(jì)數(shù)器部分利用電磁感應(yīng)原理獲取工作波或工頻過(guò)電壓電流信號(hào)，然后在顯示器上經(jīng)微處理器處理，記錄動(dòng)作次數(shù)
Long press the "F" key, then "CLR" will prompt whether all counts are cleared, and "-" will be displayed. After a "-" appears Execute the reset operation, and release the "F" key to exit before a "-" appears; 5. After pressing "▲" and "▼" at the same time to enter the setting state, the "year" bit flashes first, which can be adjusted by up and down keys; adopt Short touch "F" to switch to "month", "day", "hour", "minute" and "second" in sequence. When the second adjustment is over, short touch "F" to display the address code of the counter. If adjustment is needed, press "▲" and "▼" to adjust, and the adjustment will take effect immediately; During the adjustment, if the operation stops at any position for more than 7S, the standby state will be restored automatically, and the previous adjustment is effective. 6. Relevant data can be managed by background software through 485 bus;
Data can be downloaded and analyzed with special software through mobile computer and 485-232 transfer interface. Overall dimension, installation method and wiring diagram Overall dimension
