Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0036] The invention provides a method for designing a prefabricated concrete grounding grid, which is characterized in that: the grounding grid is composed of a plurality of prefabricated concrete modules that can be spliced, and a horizontal grounding grid structure formed by connecting several horizontal wires and longitudinal wires is arranged in the concrete module, At the intersection of the horizontal wire and the longitudinal wire, a grounding electrode ...

Abstract

The invention relates to a precast concrete grounding grid designing method. A substation ground grid is formed by splice a plurality of precast concrete formwork, Each precast concrete formwork is poured by embedding a grounding grid, and the edge of the formwork is overlapped by a step-type bus bar. The grounding grid includes a horizontal grounding grid and a grounding electrode which passes through the concrete formwork vertically downward. The construction of the grounding grid is completed after each concrete formwork is placed stably. The invention has the advantages that the groundinggrid structure is optimized, the grounding grid structure is suitable for the safety performance requirements of soft soil, frozen soil and other geological conditions, the construction period is short, the protective property of the grounding grid is enhanced, and the operation safety of the grounding equipment is ensured.

Description

technical field [0001] The invention relates to the field of grounding grids, in particular to a design method for prefabricated concrete grounding grids. Background technique [0002] The substation grounding grid must meet the requirements of grounding resistance, safe step voltage and contact potential to meet the personal safety of workers in the substation and the safe operation of various electrical equipment. The surface permafrost formed in the freezing season in seasonally frozen regions and the impact of groundwater on the soil environment in wet seasons have a serious impact on the safety performance of the ground network, resulting in a decline in the safety performance of the ground network. [0003] At present, the laying method of grounding grid is usually to bury the grounding grid under the soil layer, lay the horizontal grounding grid in the soil layer, arrange short vertical grounding electrodes around the grounding grid and at the intersection of internal...
