Movable Insulating Barrier Panel for Compact Metering Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical equipment enclosures, particularly metering panels, are bulky and occupy excessive space due to the need for insulation barriers that hinder maintenance access and are difficult to move during maintenance work.
Innovation Solution
A compact electrical equipment enclosure design with movable electrically insulating barrier panels that remain within the enclosure, allowing for reduced spatial requirements and facilitated maintenance by providing access while maintaining insulation between phases, using guiding means to position the panels between working and access positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed insulation barriers are used between phases, then electrical insulation is ensured, but maintenance access is hindered and the equipment becomes bulky
Solution Approach 1:
The barrier panel is made movable between a first position for maintenance access and a second position for electrical insulation, transforming a static insulating structure into a dynamic one that adapts to different operational requirements
Solution Approach 2:
The enclosure space is divided into separate phase compartments by the barrier panel, which can be positioned to either isolate phases for insulation or be moved to allow access to electrical components for maintenance
2Ease of operation
If movable barrier panels are used to improve maintenance access, then access is facilitated, but the panels may be difficult to move and position during maintenance work
Solution Approach 1:
Guiding means are provided at specific locations within the enclosure to facilitate the movement of the barrier panel between positions, adding localized structural features that enable easy repositioning without requiring complex overall mechanisms
3Area of stationary object
If compact design is implemented to reduce spatial requirements, then space efficiency is improved, but access to electrical components may be restricted
Solution Approach 1:
The barrier panel transitions between fixed and movable states, allowing the compact enclosure to provide both space efficiency and maintenance access by reconfiguring the internal layout when needed

AI summary
An apparatus for electric power distribution, comprising an enclosure (102) having an access opening (104) and defining an interior space (106), at least two electrical components (214, 314, 414, 218, 220) for separate phases of electricity within the apparatus, the two components being located within the enclosure and being spaced laterally from one another, at least one barrier panel (120, 122) formed of an electrically insulating material, the barrier panel being movable in relation to the enclosure between at least two positions, and guiding means (124) for guiding the barrier panel between the at least two positions, the guiding means being adapted to guide the barrier panel to a working position in which the barrier panel is located within the enclosure and between the components (214, 314, 414, 218, 220) and is adapted to provide a barrier between the components. The guiding means (124) are adapted to guide the barrier panel (120, 122) to an access position in which the barrier panel is located within the enclosure and displaced from the components in relation to the working position of the barrier panel, and in that the barrier panel is adapted to provide access to the at least two components (214, 314, 414, 218, 220) when the barrier panel is positioned in the access position. A metering panel for medium and/or high voltage comprises the apparatus.
