Dynamic Threshold Adjustment in Electrical Installation Arrangements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical installation arrangements for consumer networks disconnect areas intended for people and pets from the network with high security settings, leading to unnecessary grid shutdowns and reduced availability, as safety parameters are not adjusted based on actual occupancy.
Innovation Solution
Incorporating a control and monitoring unit with a timer for automatic adjustment of triggering limit values and times, and using sensors to detect presence, allowing for dynamic adjustment of safety levels based on time and occupancy, thereby preventing unnecessary shutdowns and ensuring high network availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high security settings with low triggering threshold values are used in areas intended for people and pets, then protection level is improved, but network availability deteriorates due to unnecessary grid shutdowns
Solution Approach 1:
The patent implements dynamic adjustment of triggering threshold values based on occupancy detection. The system transitions from static, fixed threshold values to dynamic values that automatically adapt to current conditions. When occupancy is detected, low threshold values are applied for high protection; when no occupancy is detected, threshold values are raised to prevent unnecessary shutdowns, thus resolving the contradiction between protection level and network availability
Solution Approach 2:
The system changes the parameter of triggering threshold values based on occupancy status. By detecting presence or absence of people and pets, the control unit adjusts the threshold values accordingly. This parameter change allows the system to maintain high protection when needed while avoiding false tripping when areas are unoccupied, thereby balancing protection level and network availability

AI summary
The invention relates to an electric installation arrangement (1) for the operation of an electric consumer network (2), having at least one first switch (3) for disconnecting at least one first consumer (4) and/or one partial network (30) from the consumer network (2), at least one first sensor (5) for detecting at least one first physical variable that is induced, or can be influenced, by the consumer network (2), and at least one first tripping unit (6), which switches off the first switch (3) within a first tripping time if a first tripping threshold value that can be predetermined is exceeded by a first measured variable proportional to the first variable, and thereby disconnects the consumer (4) and/or the partial network (30) from the consumer network (2). In order to prevent unnecessary disconnections from the network and guarantee high network availability, according to the invention the electric installation arrangement (1) has at least one first regulating and control unit (7) for the definable and automatic adjustment of the first tripping threshold value and/or of the first tripping time as a function of at least one control parameter.
