Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-voltage electrical equipment distribution facilities require multiple measuring, control, and protecting means for each piece of equipment, leading to increased space, wiring complexity, and costs due to specific connection requirements and on-site installation challenges.
Innovation Solution
A high-voltage insulated adapter allows connection of measuring, control, and protecting means with a standard bushing to any bar of the high-voltage electrical equipment, using an insulating body with conductive layers to ensure uniform electric field distribution and prevent corona effects, and can be installed with either male or female bushings, minimizing the need for multiple units and reducing installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple measuring, control, and protecting means are installed for each piece of high-voltage electrical equipment, then measurement and protection coverage is improved, but space requirements and wiring complexity increase
Solution Approach 1:
The patent implements a universal adapter design that can connect to different types of bushings (male and female) and support various measuring, control, and protecting means through a standardized interface. This multi-functional adapter eliminates the need for equipment-specific connection devices, thereby reducing wiring complexity while maintaining comprehensive measurement and protection coverage across all high-voltage electrical equipment
Solution Approach 2:
The adapter serves as an intermediary component between the high-voltage electrical equipment bushings and the measuring, control, and protecting means. This intermediate device standardizes the connection interface, simplifying the wiring architecture by providing a uniform connection method regardless of the specific equipment type, thus reducing overall system complexity while preserving full measurement and protection capabilities
2Adaptability or versatility
If on-site installation of measuring, control, and protecting means is performed, then adaptability to existing equipment is improved, but installation errors and time consumption increase
Solution Approach 1:
The adapter is designed with pre-configured connection features and standardized interfaces that are prepared in advance during manufacturing. The adapter includes pre-arranged connection terminals, insulating structures, and mounting features that eliminate the need for complex on-site customization, thereby reducing installation time while maintaining full adaptability to existing high-voltage electrical equipment through its universal compatibility design
