Product Introduction

The RY-NS series controllable and optimized early discharge lightning rod is an upgraded product that is based on the conventional early discharge lightning rod and has undergone technological optimization and improvement. It is a new type of early streamer emitter and lightning arrester developed and produced based on lightning electrical characteristics. During the formation of lightning, this lightning arrester triggers a continuous upward lead within its protection radius earlier than other products. The product has a larger pre discharge time (△ T) compared to conventional pre discharge lightning rods, which ensures that the RY-NS series controllable optimized pre discharge lightning rod can trigger continuous upstream leads earlier during operation, thereby intercepting downstream leads (lightning strikes) over a larger distance and ultimately protecting a larger area from lightning strikes.

working principle

In practical applications, the working principle of the RY-NS series controllable optimized early discharge lightning rod is as follows:

1. In the comprehensive environment of thunderstorm weather, when lightning clouds form in the air, an electric field is generated in the atmosphere between the clouds and the ground, with a strength of up to 14 kV/m. Such a strong electric field causes corona discharge to appear on the protruding parts of the ground or metal components; (See Figure 1-1)

2. When a downward leader is formed inside the lightning cloud layer, lightning strikes begin, and the downward leader charges develop towards the ground in a stepped manner. The charges carried by the downward leader establish an electric field on the ground; (See Figure 1-2)

3. A rising precursor is generated from a building or object on the ground, which propagates upwards until it merges with a descending precursor, at which point lightning current flows through the formed channel. A single building on the ground may generate several ascending leads, and the first ascending lead that converges with the descending lead determines the location of the lightning strike; (See Figure 1-3)

4. Pre discharge lightning rod in advance is achieved by actively triggering the built-in high-voltage pulse generator system to generate a faster upstream pilot than ordinary lightning rods, thereby achieving active lightning protection. (See Figure 1-4)

The RY-NS series controllable optimized early discharge lightning rod is optimized based on the working process of the early pre discharge lightning rod. It is equipped with an early streamer emission device developed according to the electrical characteristics of lightning, which can trigger the continuous upward pilot (i.e. continuous early pre discharge) of the lightning arrester within its protection radius earlier than other products.

Product Technical Features

Superior performance, under the same conditions (installation height), the RY-NS series controllable optimized early discharge lightning rod has a wider protection range than ordinary lightning rods.

Not limited by environmental conditions, it can work in harsh weather conditions, with high accuracy in lightning strikes, reducing the probability of protected objects being struck by lightning.

Compared to conventional pre discharge lightning rods of the same height, it has a larger protection range and lower lightning current wave head steepness.

Safe and reliable, it only self activates when lightning is about to occur (when the electric field rises), and does not pose a threat to the surrounding environment. No radioactive elements, stainless steel material, corrosion-resistant, strong wind resistance.

? Maintenance free, passive, no power supply required, no energy consuming components.

Easy to install, lightweight, no need to install coaxial shielded cables.

Beautiful appearance.

5. 95% of the rainwater insulation performance test is conducted according to IEC-EN 60060-1:2012. The patented design of RY-NS series controllable optimized early discharge lightning rod can prevent rainwater from establishing contact between the metal shell (blue) and the grounding metal rod (red) at atmospheric potential. When thunderstorms arrive, electric energy is replenished to avoid

The excitation device of the lightning needle has a high potential difference between the insulated metal structures, which must be ensured during thunderstorm weather.

6. Environmental testing

According to the requirements of UNE21186, NF C 17-102, and NP 4426 standards, the same sample is continuously tested in an environment with high salt spray and sulfur concentration to ensure the normal operation of pre discharge lightning rods in highly corrosive environments. At the same time, a high current impulse test was conducted on the product in this environment, and a 10/350 μ s wave impulse of 100kA was applied to the lightning arrester. After multiple shocks, it still worked normally.

Product Technical Features

Pre discharge time in advance (△ T)

The RY-NS series controllable optimized early discharge lightning rod has passed all standard tests, and its different protection radius Rp is determined by the △ T coefficient for different early discharge times of the series products.

(△ T) in microseconds:

According to NFC17-102 regulations, the product's advance time (△ T) for pre discharge lightning rods is required. The earlier the upstream pilot is triggered, the greater the distance to intercept the downstream pilot, thereby protecting a larger area from lightning strikes (standard limit is △ T ≤ 60 μ s).
