NKP-LJ-02 is the lightning counting display device and the power supply lightning discharge count (SPD) supporting the display instrument, can record the number of discharge discharge lightning protection device induction lightning current action, can be clear and intuitive understanding of the impact of local lightning induction frequency, grasp the work status of the lightning protection device.
SPD work status monitoring;
Lightning accurate counting;
Strong anti-interference ability, stable and reliable display;
Beautiful appearance, simple setting and convenient installation
Application of lightning counter
NKP-LJ-02 lightning counter display is suitable for installation in power distribution box power supply lightning arrester, lightning protection module and power lightning protection box, using panel embedded structure, installed in the chassis panel, power supply must be connected to the rear side of the AC or DC power arrester, sampling mutual inductor connected in series under the lead of the lightning protector. And the power lightning protection device remote access point lightning counter teleindication end with failure to indicate the power lightning protection device. The counter digital tube shows the number of lightning strokes, the "SPD invalid" lamp is bright when the lightning arrester fails, and when the counting work lamp is bright, the counting work is normal.
In the installation of lightning protection of power line power supply device by induction lightning intrusion impact, under the lead of the lightning protector is lightning currents larger, the wire is penetrated in the special transformer, will access the induction current signal NKP-LJ-02 lightning counting display, can be collected by the number of lightning pulse counter display.
When the power supply lightning protection module fails, the remote contact point of the lightning protection module is shifted, and the contact point is connected with the NKP-LJ-03 intelligent lightning action recorder, which can record and record the failure of the lightning protection module.
NKP-LJ-02 lightning count display is controlled by a single chip computer circuit, with high brightness LED digital tube display, the highest count is 99 times, recording data stored in the FLASH circuit, without falling film, can be long-term preservation. The counter has the advantages of beautiful appearance, convenient installation, strong anti-interference ability and stable and reliable display.
