產(chǎn)品特點：三相集中計數(shù)，放電時間條形記錄，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，通過避雷器的泄漏電流變化通過采樣器及相關電纜傳輸至顯示器，并通過顯示器中的放大電路和a/D轉換電路轉換為數(shù)字信號，在顯示器中的微處理器控制下顯示。當避雷器流過雷擊波、工作波或工頻過電壓時，強動作電流從泄漏電流測量電路傳輸?shù)椒措娐罚孤╇娏鳒y量電路受到保護。計數(shù)器部分利用電磁感應原理獲取工作波或工頻過電壓電流信號，然后在顯示器上經(jīng)微處理器處理，記錄動作次數(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
Method of use1. Connect the corresponding wiring according to the operation manual; 2. When powered on, the LCD is displayed in turn according to the sequence of phase a counting, phase B counting and phase C counting; 3. Short touch the "F" key to check phase a count, phase B count, phase C count, local address, current date and current address in turn Time, when the current time is displayed, if it is djs-ii type, press the "F" key three times to zero the leakage current value (please pull out the data cable during zero calibration).
Scope of application: 3 ~ 35kV system discrete lightning arrester without (with Series) gap; 2. Power supply: AC / DC 110 ~ 220V, ＜ 1.5W;3. Counting form: A, B and C phases are counted separately and displayed on centralized LCD; 4. Minimum capture discharge current: ＜ 10A; 5. Minimum capture pulse width: ＜ 1 μ s； 6. Leakage current monitoring range: 0 ~ 20mA; 7. Built in clock, power failure holding time: half a year; 8. Storage capacity: ＞ 2000 pieces; 9. Communication interface: 485, class Modbus protocol; 10. Independent address code can be set
通過移動計算機和485-232傳輸接口，可使用軟件下載和分析數(shù)據(jù)。
