Vertical Gas-Insulated Switchgear Compartment Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-insulated switchgears with horizontally extending switching devices face challenges in reducing depth dimension and have limited flexibility in cable connection and compartment design, leading to restricted installation area and handling limitations.
Innovation Solution
The design features a circuit breaker compartment with a vertical contacting/separating direction, separate connection compartments for cable terminals, and an operating mechanism positioned externally, allowing for enhanced flexibility in compartment arrangement and cable connection, reducing the installation area and facilitating manufacturing handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the circuit breaker is disposed horizontally in the depth direction, then the switching device can be easily connected to buses, but the depth dimension of the switchgear increases
Solution Approach 1:
The circuit breaker is rotated from horizontal to vertical orientation, changing the spatial dimension of disposition. This vertical arrangement allows cable connection compartments to be positioned above and below the circuit breaker, reducing the depth dimension while maintaining connection flexibility through multi-directional cable access
2Length of moving object
If the circuit breaker is disposed vertically, then the depth dimension is reduced, but the degree of freedom for cable connection and compartment arrangement is limited
Solution Approach 1:
The switchgear is divided into separate connection compartments that can be independently arranged above and below the circuit breaker compartment. This segmentation allows flexible configuration of cable connection points while maintaining the compact vertical structure, enabling different compartment arrangements based on specific installation requirements
3Ease of manufacture
If cable connection compartments are integrated with the circuit breaker compartment, then manufacturing is simplified, but handling and assembly become more difficult
Solution Approach 1:
The connection compartments are designed as separate modules from the circuit breaker compartment, allowing independent manufacturing and assembly. This modular approach enables easier handling and assembly during installation while maintaining manufacturing efficiency through standardized compartment designs

AI summary
A circuit breaker (1) is accommodated in a circuit breaker compartment (2) such that a contacting/separating direction of a contact of the circuit breaker is along a vertical direction, a cable terminal (11) of a first cable (6) connected to one terminal (1a) of the circuit breaker (1) via a first disconnector (5) is accommodated in a first connection compartment (12) such that a central conductor of the cable terminal is along the vertical direction, and a disconnector compartment (8) which accommodates the first disconnector 5 such that a contacting/separating direction of a contact of the first disconnector is along the vertical direction, is joined so as to be disposed between the circuit breaker compartment (2) and the first connection compartment (12). Further, a cable terminal (13) of a second cable (7) connected to the other terminal (lb) of the circuit breaker (1) is accommodated in a second connection compartment (14) such that a central conductor of the cable terminal is along the vertical direction. The second connection compartment is joined to the circuit breaker compartment (2). A circuit breaker operating mechanism (4) is disposed on an outer side, of the circuit breaker compartment (2), in the contacting/separating direction of the contact of the circuit breaker (1).
