Gas-Insulated Switchgear Manipulator Layout for Compact Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-insulated switches require separate installation of general switch manipulators, leading to increased model diversity and space requirements due to changing attachment positions, and do not effectively address wire bending issues when multiple switches are adjacent.
Innovation Solution
A gas-insulated switch design where multiple general switch manipulators are housed in a common housing, with wires routed differently around driving pulleys to minimize space and maintain consistent attachment positions, allowing for easy maintenance and ordered switching operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple general switch manipulators are housed in a common housing, then space utilization is improved and attachment position consistency is achieved, but wire routing complexity increases due to the need to prevent bending
Solution Approach 1:
The patent applies dimensional change by routing wires from different directions (front/rear, left/right) rather than uniformly from one direction. This allows wires to bypass each other in three-dimensional space, preventing bending while maintaining compact horizontal arrangement of manipulators in the common housing.
Solution Approach 2:
The patent introduces asymmetry in wire routing by having manipulators wired from different directions based on their specific positions. Instead of symmetric uniform routing, each manipulator's wire path is asymmetrically configured to avoid interference and bending, resolving the complexity issue while maintaining space efficiency.
2Reliability
If general switch manipulators are arranged with wide intervals to prevent wire bending, then wire damage is prevented, but installation space increases
Solution Approach 1:
The patent resolves the space-integrity contradiction by utilizing vertical and depth dimensions for wire routing. Wires are directed from front/rear and left/right directions, allowing them to pass above or below adjacent manipulators without requiring wide horizontal intervals, thus maintaining both wire integrity and compact space utilization.
Solution Approach 2:
The patent segments the wire routing paths for different manipulators, assigning each wire a distinct directional path (front, rear, left, right). This segmentation prevents wire interference and bending without requiring increased spacing, as each wire travels through its own designated spatial channel.
3Adaptability or versatility
If attachment position of general switch manipulator is changed according to arrangement layout, then adaptability to different configurations is improved, but device complexity increases due to multiple models
Solution Approach 1:
The patent applies universality by designing a common housing that can accommodate multiple general switch manipulators in fixed positions, with wire routing capabilities that adapt to different configurations through directional routing options. This single universal design replaces multiple specialized models, achieving configuration adaptability without increasing model diversity.
Solution Approach 2:
The patent introduces dynamic adaptability through flexible wire routing that can be configured from different directions (front, rear, left, right) depending on the specific arrangement layout requirements. The manipulator positions and housing structure remain fixed, while the wire paths dynamically adapt to different configurations, providing versatility without model proliferation.

AI summary
A gas-insulated switch includes: a breaker that cuts off a current; a plurality of general switches including a switching operation unit that opens and closes with rotation of a driven pulley; a breaker manipulator (20) that causes the breaker to perform a switching operation; a plurality of the general switch manipulators (30) including a driving pulley (32) that is rotationally driven by a motor (31); a wire (60) that transmits rotational force of the driving pulley (32); and a housing (70) that houses the breaker manipulator (20) and the general switch manipulator (30). Regarding the plurality of the general switch manipulators (30), the two general switch manipulators (30), arranged in a horizontal direction and set as a set, are disposed above the breaker manipulator (20) in the housing (70), and the wire (60) is put around the driving pulley (32) from a direction different from a direction in which another general switch manipulator (30) in the same set is disposed, in each of the two general switch manipulators (30) included in the single set.
