Modular Isolating Switch Layout for Synchronous Multi-Layer Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization of multiple layers of switch units in existing isolating switches is compromised due to increased transmission errors as the number of stacked units increases, affecting the overall operation efficiency.
Innovation Solution
The isolating switch body is designed with modularized body modules, each containing multiple layers of switch units connected by body rotating shafts, linked through a transmission mechanism perpendicular to the stacking direction, ensuring synchronous operation and reducing the switch's length in one direction.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple layers of switch units are stacked to increase the number of circuits controlled, then the functionality and circuit capacity are improved, but the transmission error between the first layer and last layer increases, causing synchronization problems
Solution Approach 1:
The patent changes the transmission direction from the stacking direction (vertical dimension) to a direction perpendicular to the stacking direction (horizontal dimension). The transmission mechanism is disposed in the middle or on one side or both sides of the body modules, with transmission shafts extending perpendicular to the stacking direction, thereby reducing transmission error by shortening the transmission path in the critical vertical dimension.
Solution Approach 2:
The isolating switch body is divided into multiple body modules, each containing a limited number of switch unit layers (e.g., two to four layers per module). These modules are spliced together along the stacking direction, with each module having its own transmission mechanism. This segmentation ensures that transmission error does not accumulate across the entire switch body, as each module maintains independent synchronous transmission.
2Adaptability or versatility
If multiple layers of switch units are stacked, then the circuit capacity is increased, but the length of the switch in the stacking direction increases
Solution Approach 1:
The patent redistributes switch units from a single vertical stack to a modular arrangement where multiple body modules are spliced together. Each module contains a manageable number of layers, and the overall structure can be configured in different spatial arrangements, effectively managing the length distribution while maintaining circuit capacity.
3Device complexity
If a traditional transmission mechanism is used along the stacking direction, then the structure is simple, but the transmission error between layers is large, affecting synchronization
Solution Approach 1:
The transmission mechanism is reoriented so that transmission shafts extend in a direction perpendicular to the stacking direction rather than parallel to it. This dimensional change allows the transmission mechanism to remain relatively simple while dramatically reducing the transmission path length in the stacking direction, thereby minimizing transmission error and improving synchronization precision.
Solution Approach 2:
The transmission system is segmented into multiple independent transmission mechanisms, each serving a specific body module. Each transmission mechanism handles only the switch units within its module, preventing error accumulation across the entire switch body while maintaining structural simplicity within each module.

AI summary
An isolating switch body, an isolating switch, and a power distribution system are provided. The isolating switch body includes body modules, where each body module includes a plurality of layers of switch units which are stacked, the plurality of layers of switch units are connected through respective body rotating shafts, and a plurality of groups of body modules are spliced to form the isolating switch body; the body rotating shafts of the switch units are linked with an operating mechanism through a transmission mechanism in a first direction perpendicular to a stacking direction. The handle shaft is rotated to drive the operating mechanism to act, and then the body modules are driven through the transmission mechanism to achieve synchronous opening and closing.
