NKP-LJ-03 intelligent lightning action recorder is a device with the power supply lightning discharge count (SPD) supporting the display instrument, can record the lightning protection device discharge time and the number of discharge induction lightning current action, can be clear and intuitive understanding of the impact of local lightning induction frequency, lightning protection device master working conditions
Product features: SPD working status monitoring, remote alarm;
Lightning accurate count, remote send;
Comprehensive management of lightning protection for power equipment;
Strong anti-interference ability, stable and reliable display;
Beautiful appearance, simple setting and convenient installation.
Application of lightning counter
NKP-LJ-03 intelligent lightning action recorder is suitable for installation in a power supply lightning arrester (power lightning arrester with pluggable structure design), power distribution box with lightning protection module and a variety of standard cabinet, the DIN35 rail installation way; the wiring work power supply terminal must be connected to the rear side of the AC or DC power arrester, sampling transformer should be connected in series under the lead of the lightning protector, teleindication teleindication and contact terminals shall be connected with the power lightning protection device, failure to indicate the power lightning protection device, two RS-485 terminals and remote intelligent management unit or integrated automation system for connection. The digital tube on the recorder shows the frequency of lightning stroke and the state of failure, and the date, time, number and reset can be set by the button under the digital tube. The "SPD invalid" lamp is bright when the lightning arrester fails, and the counting work lights indicate that the counting work is normal.
In the installation of lightning protection of power line power supply device by induction lightning intrusion impact, in the lightning protection of ground wire in a lightning current flowing through larger, through the special transformer in the lead, the discharge current signal access NKP-LJ-03 intelligent lightning action induced by the recorder, can be collected by the lightning discharge the pulse of the record.
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-03 intelligent lightning action recorder is controlled by a single-chip computer circuit, using high brightness LED digital display, can record the number and timing of lightning occurs, data in the local and remote query can be set to be connected to the power supply; lightning protection device number, can record the failure module number and failure time, and a set of dry contact output alarm signal; and with RS485 communication interface, parameters of the lightning protection module and fault discharge action for remote power integrated management system query and alarm, the lightning action recorder has the advantages of beautiful appearance, convenient installation, strong anti-interference ability, stable and reliable display.
