产品特点：三相集中计数，放电时间条形记录，通讯，电子液晶显示。DJs系列高灵敏避雷器放电记录仪的工作原理及产品组成主要由采样器、传感器、转接盒、显示器、配套传输电缆及部分电子元器件组成。在正常工作电压下，通过避雷器的泄漏电流变化通过采样器及相关电缆传输至显示器，并通过显示器中的放大电路和a/D转换电路转换为数字信号，在显示器中的微处理器控制下显示。当避雷器流过雷击波、工作波或工频过电压时，强动作电流从泄漏电流测量电路传输到反电路，泄漏电流测量电路受到保护。计数器部分利用电磁感应原理获取工作波或工频过电压电流信号，然后在显示器上经微处理器处理，记录动作次数
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
长按“F”键，“CLR”将提示是否清除所有计数，并显示“-”。在出现“-”之后执行复位操作，在出现“-”之前释放“F”键退出；5.按后“▲" 及"▼同时进入设定状态时，“年”位先闪烁，可通过上下键进行调整；采短“F”可依次切换到“月”、“日”、“小时”、“分钟”和“秒”。*二次调整结束后，短按“F”可显示计数器的地址代码。如果需要调整，请按“▲“和”▼“调整，调整立即生效；调整过程中，如果操作在任何位置停止**过7S，则自动恢复待机状态，**次调整生效。6.相关数据可通过485总线由后台软件管理；
