Protection theory of discharging lightning rod

When the thunder clouds formed, the bottom of thunder clouds will cause a lot of negative charge and the negative charge in the general strength of 7 to 15 kA. There is a strong magnetic field (as shown ) between the negative charge of thunder clouds and ground. The positive charge of ground released charge through the needlepoint of lighting rod, so that keep balance with the CB negative charge of aerosphere. The controllable lighting rod constantly absorbing and storing energy, to some extent, it releases the positive charge into aerosphere and neutralizes with the negative charge of CB. So it reduce the negative charge in the CB clouds, as well as reduce the discharge current and greatly relief the voltage sensors in order to avoid lightning intensity, and the purpose of protecting the construction.

Protection characters of controllable discharging lighting rod

In order to verify whether the controllable discharging lighting rod has achieved its design purpose, we take the following tests by positive polarity operation wave and DC.
Under the same conditions, using positive polarity operation weave, it can get the protection curve of the controllable discharging lighting rod and traditional lightning rod. During the testing, suppose the thunder clouds 8.5 m apart from the ground, in order to strictly test the protection characters of controllable discharging lighting rod, there is no additional DC electric field when we take the microwave test. It is obviously that controllable discharging lighting rod is superior to conventional lightning rod. On the main parameters and scope of protection, it is satisfactory.

1. Winding
There is a large protection area without winding. For example, when the winding rate less than 0.001%, (Apparently at such circumstance, the object protected has little opportunity to be winded.) and the protection up to 55 ° angle, compared to the traditional real lightning rod, controllable discharging lighting rod almost has no opportunity to be winded.
2. Scope of protection
When the protected object attacked by around 0.1%, (currently a point of order under the allowable value), controllable discharging lighting rod up to 66.4 ° angle, but traditional lightning rod is much more smaller than that. (Take the traditional lightning rod is more economical at strong intensive thunder area, while there still has opportunity that be struck by lighting).
3. Efficiency and application prospects
Controllable lightning rod is a widely used protection device with wide application prospects, with a high using value.

Main electrical parameters
1. Lightning rod needle h ≤ 200 m high, protection angle 65 °, and corresponding ground protection radius 2.14h, the hx height from the ground reaches 2.14 (h-hx).
2. Each discharging value is less than the average 7 KA during the thunder lighting current amplitude.
