Embodiment Construction

[0101] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0102] like figure 2 As shown in the present invention, a method for designing the size parameters of the spiral ground electrode suitable for complex environmental areas includes the following steps:

[0103] The first step is to set the finite element calculation method of the ground electrode. The finite element method is the most widely used in the numerical calculation of electromagnetic fields. The traditional finite element method is based on the variational principle, transforming the boundary value problem to be solved into the corresponding variational problem, and then using subdivision interpolation to convert the variational problem Discretization of extremum problems for ordinary multivariate functions. Here, the fini...

Abstract

The invention relates to a spiral grounding electrode size parameter design method suitable for a complex environment area. Compared with the prior art, the spiral grounding electrode size parameter design method overcomes the defect that a spiral grounding electrode size design method does not exist. The method comprises the following steps: setting a grounding electrode finite element calculation method; measuring the soil resistivity in a complex environment area; measuring ground resistance; designing the length of the spiral grounding electrode; designing the radius of the spiral grounding electrode; and designing the screw pitch of the spiral grounding electrode. According to the method for designing the specific size parameters of the spiral grounding electrode, through reasonable parameter design, it can be guaranteed that the spiral grounding electrode has good grounding performance in complex soil environments with limited axial electrode arrangement space, high resistivity and the like.

Description

technical field [0001] The invention relates to the technical field of spiral grounding electrodes, in particular to a method for designing dimension parameters of spiral grounding electrodes suitable for complex environment areas. Background technique [0002] In the grounding system of my country's power transmission network, the common laying methods of grounding electrodes are horizontal laying and vertical laying, but these two laying methods have the disadvantages of long laying distance or large buried depth in order to achieve the expected dispersion effect, and are easily affected by pipelines, Restricted by uncertain factors such as roads and geology, the grounding resistance increases and affects the normal operation of the transmission line. [0003] At present, the research on the grounding structure mainly focuses on different laying methods of grounding electrodes in different complex terrain areas. For example, in wet areas with soil resistivity ρ≤100 and area...
