Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current current measuring devices require disconnection of electric lines for monitoring, which is complex and invasive, making it difficult to detect string currents in solar installations and other applications.
Innovation Solution
A current measuring device with separable housing parts that form an accommodating device for electric lines, equipped with magnetic field sensors to detect currents without disconnecting the lines, allowing flexible arrangement on a supporting rail with other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electric lines are disconnected to install the current measuring device, then current detection can be performed, but the system complexity and intervention increase
Solution Approach 1:
The housing is divided into two separable housing parts (first housing part and second housing part) that can be opened to receive the electric line and then closed to enclose it. This segmentation allows the device to be installed without disconnecting the electric line, as the line can simply be placed between the opened housing parts, thereby reducing system intervention while maintaining measurement capability
Solution Approach 2:
The accommodating device formed by the two housing parts acts as an intermediary structure that receives and encloses the electric line without requiring disconnection. The magnetic field sensor then detects the magnetic field generated by the current flowing through the enclosed electric line, enabling current measurement while the line remains connected in the circuit
2Ease of operation
If housing parts are separable for easy installation, then ease of operation improves, but device reliability may worsen due to potential connection issues
Solution Approach 1:
The housing is segmented into two parts that can be separated for installation and then joined together. The accommodating device formed by these parts provides a structured way to receive and enclose the electric line, ensuring proper positioning and stable connection when the housing parts are assembled
Solution Approach 2:
The first housing part and second housing part are designed to join together to form a complete enclosing structure. This merging of the two separable parts creates a unified housing that securely holds the electric line and supports the magnetic field sensor, maintaining structural integrity and reliability while allowing easy installation

AI summary
A current measuring device for detecting a current in an electric line includes: a housing; a fastening device arranged on the housing for fastening the housing to a supporting rail; and at least one magnetic field sensor. The housing has a first housing part and a second housing part which together form an accommodating device for accommodating an electric line between the first and second housing parts. The first and second housing parts are separable from one another in order to place an electric line onto the current measuring device and placeable onto one another in order to accommodate the electric line in the accommodating device between the first and second housing parts. The at least one magnetic field sensor detects a magnetic field on the electric line accommodated in the accommodating device.
