High-Voltage Control System Single Actuator Blocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for high-voltage electrical devices require multiple actuators and complex locking mechanisms to perform three switching positions (making, breaking, and grounding), leading to operational errors and increased manufacturing costs.
Innovation Solution
A control system with a single actuator and transmission part that uses a blocking mechanism to move the moving contact between three switching positions, eliminating the need for complex locking mechanisms by integrating a blocking means that can slide between positions manually or motorized, attached to the actuator via a connecting rod and actuating shaft, preventing circular motion of the moving contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple actuators are used to perform three switching positions (making, breaking, and grounding), then the switching functions can be performed, but the device complexity and manufacturing cost increase due to the need for complex locking mechanisms
Solution Approach 1:
The patent applies a single actuator to perform multiple switching functions (making, breaking, and grounding) that traditionally required multiple actuators. The control system enables one actuator to sequentially operate the moving contact through different switching positions by controlling the blocking means at different times, thereby eliminating the need for multiple actuators and complex locking mechanisms while maintaining full switching capability
Solution Approach 2:
The patent uses a dynamic blocking means that can be selectively positioned to control the movement of the moving contact. The blocking means is moved to different positions at different times during operation, dynamically enabling the single actuator to achieve multiple switching functions. This dynamic control replaces static complex locking mechanisms with a simpler, time-controlled blocking system
2Adaptability or versatility
If multiple actuators and complex locking mechanisms are used, then all switching functions can be performed, but operational reliability decreases due to potential operating errors
Solution Approach 1:
The control system with a single actuator and time-controlled blocking means eliminates the need for complex interlocking mechanisms that are prone to operating errors. The simplified system reduces the number of moving parts and potential failure points, thereby improving operational reliability while maintaining the ability to perform all required switching functions
3Adaptability or versatility
If multiple actuators are used for three switching positions, then the switching functions can be performed, but manufacturing cost increases due to the large number of elements required
Solution Approach 1:
The patent employs a single actuator design that can perform all three switching functions (making, breaking, and grounding) through controlled operation of the blocking means. This universal approach eliminates the need to manufacture and install multiple actuators and associated locking mechanisms, significantly reducing manufacturing costs and the number of components required
