Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-voltage testing of energy dissipation units in a power transmission system is inefficient and labor-intensive, as it requires testing individual units separately, and existing methods to measure DC reference voltage and leakage current of multiple units connected in parallel lack precision and reliability.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual energy dissipation units are tested separately, then measurement precision of DC reference voltage and leakage current is improved, but productivity deteriorates due to heavy workload and time-consuming testing
Solution Approach 1:
The patent applies segmentation by dividing the energy dissipation device into multiple independently testable energy dissipation units, each with its own measurement integration module. This allows simultaneous testing of multiple units rather than sequential individual testing, thereby improving productivity while maintaining measurement precision through dedicated measurement circuits for each unit.
Solution Approach 2:
The patent implements universality through a common high-capacity DC power supply that can simultaneously provide test voltage to multiple energy dissipation units connected in parallel. The measurement integration modules use standardized interfaces and protocols, allowing the same testing methodology to be applied universally across all units, reducing testing complexity and improving efficiency.
2Ease of operation
If direct measurement of total DC reference voltage and total leakage current is performed without disconnecting wires, then ease of operation is improved, but measurement precision deteriorates as individual unit measurements cannot be obtained
Solution Approach 1:
The patent resolves this contradiction by segmenting the measurement function through dedicated measurement integration modules for each energy dissipation unit. These modules independently measure DC reference voltage and leakage current at each unit level while the system operates in parallel configuration, eliminating the need for wire disconnection while providing precise individual unit measurements.
Solution Approach 2:
The measurement integration modules act as intermediaries between the high-capacity DC power supply and the individual energy dissipation units. They provide isolated measurement circuits that can accurately measure electrical parameters at each unit without requiring physical disconnection or interference with the parallel connection structure, thus maintaining both ease of operation and measurement precision.
3Productivity
If multiple parallel-connected energy dissipation units are tested simultaneously, then productivity is improved, but device complexity increases due to additional measurement and control systems
Solution Approach 1:
The patent manages complexity through segmentation by creating modular measurement integration modules that can be independently configured for each energy dissipation unit. This modular approach allows simultaneous testing of multiple units while keeping each measurement system independent and manageable, preventing exponential growth in system complexity.
Solution Approach 2:
The patent applies merging by combining multiple measurement integration modules under a single control unit that coordinates testing across all energy dissipation units. The control unit consolidates data collection and analysis functions, allowing simultaneous testing to be managed through a unified interface rather than requiring separate control systems for each unit, thus improving productivity without proportionally increasing operational complexity.
