DJs series high sensitive lightning arrester discharge recorder is mainly composed of sampler, sensor, adapter box, display, supporting transmission cable and some electronic components. Under normal operating voltage, the change of leakage current through lightning arrester is transmitted to the display through sampler and relevant cables, and converted into digital ** and displayed under the control of microprocessor in the display through amplification circuit and a / D conversion circuit in the display.
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
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
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;
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).
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；
