Electrical Lightning Protection Grounding Assisted Design (LCAD)

Electrical lightning protection grounding auxiliary design (LCAD) mainly adopts the "Lightning Protection Design Code for Buildings" (GB 50057-2010) and "Grounding of AC Electrical Devices" (DL/T 621-1997) and the names and codes in its appendices.

14. Edit thunderstorm day information.

Electrical lightning protection grounding auxiliary design (LCAD) basis and method

​ 1. "Code for Lightning Protection Design of Buildings" (GB 50057-2010);

​ 2. "Grounding of AC Electrical Installations" (DL/T 621-1997);

3. Mainly adopt the "Rolling Sphere method" Method) is used to calculate the lightning protection range. The principle is to equate the thundercloud boundary to a spherical surface, and use an imaginary ball to roll along the outer contour of the protected object. The area that cannot be reached by the spherical surface is the protected area, and the area that touches or penetrates its surface is The locations are all non-protected areas.

Electrical lightning protection grounding assisted design (LCAD) software requirements

​​ 1. In principle, third-party software is not required;

​​ 2. When you need to use AutoCAD to draw, you need AutoCAD software;

3. When you need to use Excel to edit data, you need Excel software;

​ 4. Supports most popular operating systems.

Electrical Lightning Protection Grounding Aided Design (LCAD) Graphical Description

​​ 1. The default left side of the lightning protection range drawing of double lightning rods with unequal heights is the low lightning rod;

​​ 2. The default X-axis direction of the lightning protection range drawing with four lightning rods of equal height in a rectangular arrangement is the wide edge;

3. In actual projects, the orientation of the areas where lightning protection needs to be designed is diverse. When used, the lightning protection range can be flexibly rotated, flipped and other operations to meet actual needs.

Electrical Lightning Protection Grounding Aided Design (LCAD) Data Description

​​ 1. The data in all text boxes on the software interface are exemplary data and must be entered according to the facts when using it;

​​ 2. The number of thunderstorm days in major cities and towns across the country provided with the software is collected by the author and should be verified by yourself when using it.

Design and verification of lightning protection devices for buildings

You can summarize its use based on your experience. For example, you can determine the number and location of lightning protection devices, and you can verify whether your lightning protection device design is economical and reasonable.
