Working principle of product
The lightning protection device is based on the principle of standing wave antenna and lightning wave spectrum design. The main part is a short rod equivalent to the end of the 1/4 wavelength. When the signal is sent out, a part of the impedance is reflected back because the impedance is not fully matched, and the wave will form a standing wave when the wave is superimposed on the incident wave originally emitted. The amplitude of standing wave at each point of the line is fixed first. For the transmission line with terminal short circuit, the terminal is short circuited, so the current is large and the voltage is small. For the signal end, the voltage and the current are small.
That is, the most close to the open circuit of the signal terminal impedance, so the loss is small, but for the lightning wave because of its wide spectrum range, and most of the energy is concentrated in the frequency band below 10HZ, so the short circuit rod is short circuited to the lightning, and will not invade the equipment to cause damage.
1. built in fast semiconductor protection device, with fast response speed.
2. high transmission frequency, small insertion loss
3. extremely low stationed Bobbi, ensure that the lightning arrester does not interfere with the normal operation of the system.
Use of attention
1. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.
2. in order to reliably prevent thunder and lightning, we can connect each antenna output terminal and the input terminal of the protected device to a lightning feeder. In areas where lightning is less, there can be only one antenna without amplifier.
3. in the outdoor antenna lightning protection device must pay attention to rain, don't let the internal corrosion damage caused by rain water immersion.
