Carrier Platform Insulator Configuration for High-Voltage Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for carrying high-voltage equipment are material-intensive and complicated to produce, with difficult assembly due to the large number of joints required.
Innovation Solution
The device features two supporting insulators extending in an inclined, V-shaped configuration from each mount, reducing the number of insulators needed and allowing the load to be absorbed by the other insulator in case of fracture, with a symmetrical, cost-effective design and articulated connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perpendicular supporting insulators are used to hold the carrier platform, then the platform can be supported in a straightforward manner, but the device becomes material-intensive and requires a large number of insulators
Solution Approach 1:
The patent changes the spatial arrangement of supporting insulators from a perpendicular configuration to an inclined configuration. By arranging insulators at angles rather than perpendicular to the platform, the structure achieves better load distribution and redundancy with fewer insulators, resolving the contradiction between reliability and quantity.
Solution Approach 2:
The patent employs asymmetric inclination angles for the supporting insulators relative to the vertical axis. This asymmetric arrangement optimizes the load path and ensures that failure of one insulator does not compromise the entire structure, achieving reliable load absorption with reduced material usage.
2Reliability
If multiple supporting insulators are arranged in independent rings with bracing means, then load absorption in case of fracture is ensured, but the device complexity and number of joints increase
Solution Approach 1:
The patent merges the functions of multiple supporting insulators into a unified inclined arrangement. Instead of using separate insulators in independent rings with additional bracing, the inclined configuration inherently provides both support and redundancy, eliminating the need for separate bracing means and reducing overall complexity.
Solution Approach 2:
The inclined arrangement of supporting insulators creates inherent redundancy where each insulator shares the load with others. This beforehand cushioning ensures that if one insulator fractures, the load is automatically redistributed to the remaining insulators, maintaining structural integrity without requiring additional protective bracing.
3Reliability
If two groups of four supporting insulators are arranged in independent rings, then reliable load absorption is achieved, but assembly becomes difficult due to large number of joints
Solution Approach 1:
The patent segments the supporting structure into fewer, independently adjustable inclined insulator units. This segmentation allows for simpler assembly where each unit can be positioned and secured independently, reducing the overall number of joints and simplifying the assembly process while maintaining reliability through the redundant inclined configuration.

AI summary
A device for carrying high-voltage equipment in an electrically-insulated manner includes electrically non-conductive support insulators that are configured for mounting a carrier platform, which receives the high-voltage equipment, on a foundation in an electrically-insulated manner. Each support insulator extends towards the foundation from a bearing connected to the carrier platform. In order to provide such a device which is cost-effective and easy to produce, two support insulators extend at an incline from each bearing and the two support insulators form an acute angle with respect to their shared bearing.
