Innovation Solution
A lightning suppression system comprising a charged body on a structure with a capacitor configuration, where the capacitor is grounded and includes a first electrode body connected to the ground and a second electrode body opposed via an insulating layer, generating negative charges to suppress lightning without the need for large structural changes, allowing for separate installation on the ground and using existing structural elements like jewels or lightning rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the capacity of the capacitor is increased to enhance the lightning suppression effect, then the quantity of negative charges increases, but the arrester increases in size and installation complexity
Solution Approach 1:
The capacitor is divided into two separate electrode bodies (first electrode body grounded, second electrode body connected to charged body) that can be installed independently. This segmentation allows the capacitor components to be installed on the ground rather than requiring complete assembly at high altitude, reducing installation complexity while maintaining the required capacitance for sufficient negative charge generation.
Solution Approach 2:
The patent introduces a cable as an intermediary connection element between the second electrode body and the charged body. This allows the capacitor to be installed on the ground with electrical connection to the high-altitude charged body, eliminating the need to install large-capacity capacitors at difficult-to-reach heights while still achieving the required charge storage capacity.
2Quantity of substance
If a large-capacity capacitor is installed on the ground, then the quantity of negative charges increases for better lightning suppression, but the installation operation becomes more complicated
Solution Approach 1:
By segmenting the capacitor into separately installable electrode bodies connected by cable, the system allows ground-level installation of the main capacitor components. This eliminates the need for complex high-altitude assembly operations while maintaining sufficient negative charge capacity for effective lightning suppression.
Solution Approach 2:
The system utilizes existing structural elements (such as lightning rods or architectural features like jewels) as the charged body, eliminating the need to construct separate high-altitude mounting structures. This self-service approach simplifies installation by leveraging already-present structural components.
3Reliability
If the arrester is installed at a high place on the protected object, then the protection region is effectively formed, but the installation operation becomes complicated
Solution Approach 1:
The cable acts as an intermediary that connects the ground-level capacitor to the high-altitude charged body. This allows the bulk of the installation (the capacitor) to occur at ground level while still maintaining the required high-altitude charge distribution for effective protection region formation.
Solution Approach 2:
The solution separates the installation space from the operational space by connecting the ground-level capacitor to the high-altitude charged body through vertical cable connection. This dimensional separation allows easy ground-level installation while maintaining the high-altitude position necessary for protection effectiveness.
