Problems solved by technology

The traditional lightning protection design of the rolling ball method is to establish the number, height and position of lightning rods through formula calculation. The protection range of lightning rods is mainly represented by a series of abstract data or by drawing a plan. Disadvantages such as large investment

Embodiment Construction

[0030] (5) Take the P1 point as the center of the circle, and make a circle with a radius of hr, which intersects with L1 at two points X1 and X2.

[0033] (8) use the "rotation to create an entity" command to generate a single lightning rod protection range Z1 along the lightning rod axis.

[0034] (9) Using the same method, the single-pin protection ranges Z2 and Z3 of the other two lightning rods are established.

[0035] (10) The protection ranges of the three lightning rods at the ground height intersect at points B1, B2 and B3, respectively.

[0037] (12) Using the "pull-up to create an entity" command, with hr as the pull-up height, the lift-up body Z4 is created upward.

[0039] (14) Using the "extract entity" command, use the spheres S1, S2 and S3 to cut Z4 respectively to form a cut body Z5.

[0040] (15) The smart line is used to connect the three needle vertices in turn, to form a triangle T1, and to make the circumcircle C1 of T1.

[0042] (17) Using the "extract entity...

Abstract

The invention discloses a method for constructing a three-needle joint protection range model based on the rolling ball method, which accurately and intuitively expresses the relationship between the protection range of three contour lightning rods and the protected object in a three-dimensional visualization manner, which is convenient for engineering design Personnel can check at a glance whether the protected object is effectively within the lightning protection range of the lightning rod.

Description

A method for constructing a three-needle combined protection range model based on the rolling ball method technical field The invention belongs to the lightning protection method field, relate in particular to a kind of construction of three-pin joint protection scope based on rolling ball method method of the model. Background technique Since the invention of the lightning rod in the 18th century, it has played an important role in the field of lightning protection, and has contributed to the safety of people's lives and property. All made great contributions. Direct lightning strikes into the transmission network, which will cause a counterattack to the electrical equipment, damage the electrical equipment, and cause a shutdown. Electric accidents cause huge economic losses. [0003] Therefore, in the design of substation engineering, the importance of lightning protection design is self-evident. Traditional rolling ball lightning protection design The number, he...
