Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for measuring and monitoring electrical parameters on low-voltage board fuseholder bases are complex to install, often require additional space, and can lead to hot spots due to extra connection points, making them unsuitable for existing installations and prone to accessibility issues.
Innovation Solution
A three-pole vertical fuseholder base with integrated means for anchoring current sensors within its housing, allowing for easy installation and removal of sensors without adding new connections, ensuring the sensors are protected and accessible, and compatible with existing fuseholder bases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current transformers or current sensors are installed between the fuseholder base and the low-voltage board, then electrical parameters can be measured and monitored, but the installation complexity increases and additional connection points create hot spots
Solution Approach 1:
The patent integrates current sensors directly into the fuseholder base structure, merging the measurement function with the existing electrical connection structure. This eliminates the need for separate current transformers and additional connection points, thereby reducing installation complexity while maintaining measurement capability
Solution Approach 2:
The fuseholder base is designed to serve multiple functions: it provides electrical connection, houses fuses, and integrates current sensing capability. This multi-functionality eliminates the need for separate measurement devices and reduces the overall system complexity
2Measurement precision
If modules with current transformers are connected to the fuseholder base, then electrical parameter data can be obtained, but additional space is required and hot spots appear due to extra connection points
Solution Approach 1:
The current sensors are integrated within the existing fuseholder base housing, merging the measurement function into the existing structure. This eliminates the need for separate measurement modules and additional connection points, thereby saving space on the distribution board while maintaining measurement capability
Solution Approach 2:
The current sensors are housed within the existing fuseholder base structure, nesting the measurement function inside the existing component. This utilizes the available space within the base rather than requiring additional external space on the distribution board
3Measurement precision
If current transformers are installed on the rear side of the base, then electrical parameters can be measured, but accessibility and visibility are reduced and installation becomes more difficult
Solution Approach 1:
Instead of placing sensors on the rear side of the base where they are hidden and difficult to access, the patent positions the current sensors on the front side of the fuseholder base. This inversion of the conventional placement makes the sensors visible and easily accessible for installation, maintenance, and inspection while maintaining their measurement function

AI summary
The present invention refers to a vertical fuseholder base, preferably for NH type fuses, which is provided with means for the measuring and/or monitoring of different electrical parameters and which basically comprises a base plate (1) in which there are housed pairs of contacts (2), a fuse (6) connected to each pair of contacts (2), so that it may be coupled to and uncoupled from them, thereby opening and closing the electrical circuit, at least one connection terminal (3) to provide power supply at a load, and a housing (4) situated in the area of the connection terminals (3) for the installation of at least one current sensor (5).
