Cable Antistress Cone Cutting for Standardized Joint Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for forming antistress cones in high-voltage cable joints are manual, time-consuming, and result in low-quality, non-standardized cones due to the use of different insulation materials, leading to inefficiencies and safety concerns.
Innovation Solution
A device comprising a support, clamping unit, cutting unit, and infeed unit that automatically processes the antistress cone by clamping the cable, cutting in the radial direction, and feeding in the axial direction to form a conical surface, ensuring stable and uniform electric field distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cutting method is used to form antistress cone, then operation flexibility is maintained, but processing efficiency is low and quality is poor
Solution Approach 1:
The cutting unit is designed to automatically perform cutting operations without manual intervention. The infeed unit automatically feeds the cable into the cutting unit, and the clamping unit automatically secures the cable, creating a self-service system that eliminates manual cutting while maintaining operational simplicity
Solution Approach 2:
The patent replaces the manual mechanical cutting system with an automated cutting unit that uses a cutting blade driven by a motor. The infeed unit uses a feeding mechanism to automatically advance the cable, substituting manual mechanical operations with automated mechanical systems to improve efficiency
2Productivity
If automated cutting device is introduced, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The support structure serves multiple functions: it holds the clamping unit, cutting unit, and infeed unit, and provides a stable base for all operations. The clamping unit not only secures the cable but also positions it for cutting. This multi-functionality reduces the need for separate dedicated components, simplifying the overall device structure while maintaining automation
Solution Approach 2:
The patent combines the clamping, cutting, and infeed functions into a single integrated device mounted on a common support. The cutting unit and infeed unit are merged into one assembly that works协同, reducing the number of separate devices needed and simplifying the overall system complexity
3Manufacturing precision
If manual cutting is used, then device complexity is low, but manufacturing precision is poor
Solution Approach 1:
The manual cutting operation is replaced with an automated cutting unit that uses a motor-driven blade. This mechanical substitution ensures consistent cutting depth and angle, improving the precision of the antistress cone formation while maintaining a relatively simple device structure through the use of standard mechanical components
