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
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).
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
使用方法 按照操作手册连接相应的接线;2.通电时,LCD按a相计数、B相计数、C相计数顺序依次显示;短“F”键,依次检查a相计数、B相计数、C相计数、本地地址、当前日期和当前地 时间,当显示当前时间时,如果是djs ii型,按“F”键三次,将泄漏电流值归零(归零校准时请拔出数据电缆)。
