雷击计数器TNR-JA

特点：

雷击计数器可记录各种防雷装置的雷击和瞬间过电压次数。计数次数为两位数，最高为99次。雷击计数器安装于电涌保护器的接地线上，动作电流为±3KA(8/20μs)，最高计数电流为150KA(8/20μs)。

雷击计数器配有电流互感器。安装使用时，把电流互感器套入电涌保护器的PE线上，互感器的次级线圈的两根线引入雷击流计数器的接线柱，牢固连接，按下显示开关，即可显示记录次数。

Applicable to a variety of lightning protection lightning counter device counts the number of lightning current discharge. Count the number of double-digit expansion of the past can only be a bit count function, up to 99 times. Lightning counter installed on the need to discharge lightning current of the lightning protection module, such as the surge protector grounding line, initial count of current 1KA(8/20μs), the highest count of current 150KA(8/20μs). Lightning counter power to protect the data inside the power supply up to 1 month. Lightning counter is equipped with current transformers. Installation when the current transformer core set of the PE into the surge protector line frequency tranformer coil two-line introduction of lightning counter 5,6 terminal, solid connection. There surge occurs, the surge protector lightning discharge flow, the induced lightning current transformer, coupled to the counter after sampling, the counters through the internal IC signal processing, after the thunder and lightning, in the LED digital tube display switch on the press, which shows that the number of lightning current discharge. Lightning current counter has six terminals, 1,2 two terminal then N, L lines for the counter to provide charging power supply; intermediate 3,4 2 terminal, the short counter then what can be achieved re-zero; 5,6 2 the introduction of a terminal current transformer coil two lines.
