Composite Direct Connector for High Voltage Line Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high voltage line grounding methods lead to fault contacts, reduced workspace, and accelerated deterioration due to exposed neutral lines, causing safety accidents and increased construction costs.
Innovation Solution
A composite direct connector for high voltage lines that eliminates the need for external grounding of neutral lines, allowing for both ground and non-ground connections using a connecting member, which includes terminal connecting rings, ground terminals, and a shield line with a hollow portion for main line accommodation, along with a connecting member that secures the ground rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the neutral line is grounded via a clamp outside the high voltage line, then grounding protection is provided, but fault contact occurs due to mixing of neutral lines in manholes and workspace is reduced
Solution Approach 1:
The patent merges the neutral line connection function and grounding function into a single integrated connector. The connector includes a body with a neutral line insertion hole and a grounding terminal that can be coupled with a ground rod, eliminating the need for separate clamps and external grounding connections. This integration resolves the workspace reduction problem while maintaining grounding protection.
Solution Approach 2:
The connector is designed to perform multiple functions: connecting neutral lines from different high voltage lines and providing grounding capability through the coupled ground rod. This multi-functional design eliminates the need for separate grounding clamps and external grounding structures, improving ease of operation while maintaining reliability.
2Reliability
If the neutral line is exposed to the outside of the high voltage line, then grounding connection is enabled, but dirt adheres to the neutral line accelerating deterioration and causing defective contact
Solution Approach 1:
The neutral line is inserted into the connector body through an insertion hole, placing it inside a protected structure rather than exposing it externally. The grounding terminal is coupled with a ground rod that is also housed within the connector body. This nesting arrangement protects the neutral line from dirt adhesion while maintaining grounding connection capability.
Solution Approach 2:
The connector body acts as a protective enclosure that shields the neutral line and grounding components from environmental contaminants. The structured housing prevents dirt from adhering to the neutral line while allowing electrical connections to be maintained inside the protected space.
3Reliability
If external grounding structures are used, then grounding is achieved, but construction cost and material cost increase
Solution Approach 1:
The patent combines the neutral line connector and grounding device into a single integrated component. The connector body includes both the neutral line insertion hole and the grounding terminal, eliminating the need for separate grounding clamps, external grounding wires, and additional installation materials. This integration reduces both material costs and construction costs while maintaining grounding reliability.
4Reliability
If neutral lines are connected externally, then grounding is provided, but the structure becomes complex and space utilization is reduced
Solution Approach 1:
The patent integrates the neutral line connection structure and grounding structure into a single connector body. The neutral line insertion hole and grounding terminal are combined within the same housing, eliminating the need for separate external grounding structures and reducing overall structural complexity. This simplification improves space utilization while maintaining grounding protection.

AI summary
The present invention relates to a composite direct connector for a high voltage line. The composite direct connector for a high voltage line according to the present invention is characterized by comprising: a pair of terminal connecting rings electrically connected to each other; and ground terminals installed on the terminal connecting rings, respectively, and having a neutral line of a high voltage line on one side and a neutral line of a high voltage line on the other side connected to each other. According to the present invention as described thus far above, a neutral line for connecting a high voltage line and for external grounding is rendered unnecessary by a connecting member, thus making it easy to arrange ground wires within a structure, and affording easy construction without regard to access space.
