　　LOVOS避雷器頻率范圍覆蓋48到62赫茲，適用于戶內(nèi)及戶外應(yīng)用。標(biāo)稱放電電流為5 kA或10 kA。連續(xù)工作電壓Uc為280 V, 440 V, 500 V或660 V。

　　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(jì)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(jì)數(shù)。可記錄避雷器a、B、C放電動(dòng)作次數(shù)及相應(yīng)放電時(shí)間，液晶顯示，數(shù)據(jù)記錄量1000次以上，抗干擾能力強(qiáng)，靈敏度高，并提供網(wǎng)絡(luò)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.

　　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，通過避雷器的泄漏電流變化通過采樣器及相關(guān)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(hào)，在顯示器中的微處理器控制下顯示。

　　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;

　　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).

　　通過移動(dòng)計(jì)算機(jī)和485-232傳輸接口，可使用軟件下載和分析數(shù)據(jù)。
