Multi-directional top-cover grounding grid spacer assembly and construction method thereof

Abstract

A multi-directional top-cover grounding grid spacer assembly includes a bottom groove, a spacer, a spacer top cover, and a plate-like latch. The bottom groove is a linear structure. A first groove isdisposed on the center of the bottom groove and passes through the two end surfaces of the bottom groove. The side surfaces of the bottom groove are provided with second grooves penetrating through both side surfaces of the bottom groove. A plurality of third grooves are disposed on one side surface of the bottom groove along its horizontal direction. The bottom of the spacer is provided with a first hemisphere rotatable in the first groove. The side surface of the bottom of the spacer is provided with two crossed through slots each of which is configured as a *-shaped structure. One end of the spacer top cover is configured to fix a grounding body. The other end of the spacer top cover is in threaded connection to a screw hole at the top of the spacer. The plate-like latch includes a fixed plate and a latch. The latch is a cross-shaped structure and is inserted into the through slots. The fixed plate is inserted into the third groove. The multi-directional top-cover grounding grid spacer assembly not only has high reliability and simple operation, but also has a firm connection, a wide range of applications, and easy installation and removal.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a multi-directional roof-type grounding grid spacer assembly and a construction method thereof, which are mainly suitable for realizing the space between two grounding bodies laid in parallel or crosswise in a grounding ditch. Background technique [0002] The grounding network of power system transmission poles and towers is an important power infrastructure for transmission lines to prevent lightning damage, and its good grounding characteristics are important factors that can effectively prevent tower top overvoltage and insulator flashover. In order to solve the phenomenon that the grounding grid is easy to corrode and break, the current tower grounding grid has begun to use non-metallic conductive materials such as flexible graphite composite grounding materials as the grounding body in the construction of poles and towers in recent years. Flexible graphite composite grounding m...
