Abstract

The invention provides a method and a device for optimizing layout of lightning arresters of a multi-lightning-rod system. The method comprises the following steps: acquiring a preset protection rangeof the multi-lightning-rod system; determining constraint conditions for layout optimization of the lightning arresters of the multi-lightning-rod system according to a preset protection range; determining a position height relation function based on the constraint condition and a preset height optimization model; wherein the position height relation function is a relation function between the optimal height of the lightning arrester in the multi-lightning-rod system and the plane position of the lightning arrester for all protection points; and determining the plane position of each lightning arrester in the multi-lightning-rod system based on the constraint condition and a preset position optimization model, and determining the height of each lightning arrester in the multi-lightning-rod system according to the plane position of each lightning arrester in the multi-lightning-rod system and the position height relation function. According to the method and the device for optimizing layout of lightning arresters of the multi-lightning-rod system, rapid and reasonable layout of the lightning arrester of the multi-lightning-rod system can be achieved.

Description

technical field [0001] The invention belongs to the technical field of lightning protection design, and more specifically relates to a method and a device for optimizing the layout of lightning receptors in a multi-lightning rod system. Background technique [0002] For urban buildings or outdoor facilities, a single lightning rod system is often difficult to meet the protection design requirements, and multiple lightning rod systems are usually required for combined protection. For this reason, how to rationally optimize the layout of the plane position and height of each air-termination device in a multi-lightning rod system is a key issue in the design of direct lightning protection. [0003] As for the layout optimization of air-terminations in a multi-lightning-rod system, the core is to determine the height and plane installation position of each air-termination in the system. The main solutions in the prior art are the empirical method or the drawing and trial method...
