　　LOVOS是由金屬氧化物包裹與防紫外的聚酰胺外殼的無間隙避雷器，可通過避雷器頂端的螺絲連接到架空線路。接地底座為單孔平板連接器，LOVOS可以配以開斷裝置。

　　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(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(zhuǎn)換電路轉(zhuǎn)換為數(shù)字信號，在顯示器中的微處理器控制下顯示。

　　DJs百度系列高靈敏避雷器放電記錄儀功能簡介DJs系列高靈敏避雷器放電記錄儀（以下簡稱DJs）是一種用于室內(nèi)使用的電子式避雷器放電計數(shù)器（可選避雷器泄漏電流在線監(jiān)測）。適用于35KV以下無（串聯(lián)）間隙避雷器的放電計數(shù)�？捎涗洷芾灼鱝、B、C放電動作次數(shù)及相應放電時間，液晶顯示，數(shù)據(jù)記錄量1000次以上，抗干擾能力強，靈敏度高，并提供網(wǎng)絡通信和數(shù)據(jù)下載接口。

　　Long press the "F" key, then "CLR" will prompt whether all counts are cleared, and "-" will be displayed. After a "-" appearsExecute 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; adoptShort 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;

　　7. 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

　　1. 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. Commnication interface: 485, class Modbus protocol; 10. Independent address code can be set

　　Method of use

　　1. 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).

　　使用方法

　　1.按照操作手冊連接相應的接線；

　　2.通電時，LCD按a相計數(shù)、B相計數(shù)、C相計數(shù)順序依次顯示；

　　3.短按“F”鍵，依次檢查a相計數(shù)、B相計數(shù)、C相計數(shù)、本地地址、當前日期和當前地址

　　時間，當顯示當前時間時，如果是djs ii型，按“F”鍵三次，將泄漏電流值歸零（歸零校準時請拔出數(shù)據(jù)電纜）。

　　4.長按“F”鍵，“CLR”將提示是否清除所有計數(shù)，并顯示“-”。在出現(xiàn)“-”之后

　　執(zhí)行復位操作，在出現(xiàn)“-”之前釋放“F”鍵退出；5.按后“▲" 及"▼同時進入設定狀態(tài)時，“年”位先閃爍，可通過上下鍵進行調(diào)整；采用短按“F”可依次切換到“月”、“日”、“小時”、“分鐘”和“秒”。第二次調(diào)整結(jié)束后，短按“F”可顯示計數(shù)器的地址代碼。如果需要調(diào)整，請按“▲“和”▼“調(diào)整，調(diào)整立即生效；調(diào)整過程中，如果操作在任何位置停止超過7S，則自動恢復待機狀態(tài)，前一次調(diào)整生效。6.相關數(shù)據(jù)可通過485總線由后臺軟件管理；
