Electric installation arrangement and method for the operation of an electric installation arrangement

Abstract

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.

Description

technical field [0001] The invention relates to an electrical installation system for operating an electrical consumer network, the electrical installation system comprising: at least one first switch for disconnecting at least one first consumer and / or sub-network from the consumer network open; at least one first sensor, used to detect at least one first physical variable induced or influenced by the network of electric appliances; When a first measured variable, which is proportional to a variable, is exceeded, the triggering unit switches off the first switch within a first triggering time and thus disconnects the consumer and / or the partial network from the consumer network. Background technique [0002] In conventional electrical installations for operating electrical consumer networks, protective devices are provided by means of which individual consumers can be switched off if, for example, safety-relevant parameters (e.g. fault current) exceed threshold values. Or ...

Problems solved by technology

This results in: adjusting areas set up for people and / or pets to high security levels and (thus) low trigger thresholds, which may lead to unnecessary network shutdowns and thus may render devices unusable or unusable at all times, although Shutdown of said network may not occur due to absence of residents and thus no danger to body and life
