Embodiment Construction
[0028] A general concept of operating an electrical switching device in an electrical switching system will be described hereinafter with reference to the accompanying drawings.
[0029] An electrical switching system 41 in the medium voltage range is shown as an example for the transmission and / or distribution of the medium voltage of the supply to downstream networks and / or users. Such an electrical switching system 41 comprises a plurality of functional units 42 which are arranged in an enclosure housing or housing module 43 . The different components are arranged in the functional unit 42, in particular an electrical switching device 44 is housed for controlling and regulating the switching system. Electrical switching devices are, for example, circuit breakers, isolating switches, earthing switches, circuit breakers and / or inverters. The switch system 41 , the functional units 42 and the electrical switchgear 44 are electrically connected to each other and to the medium ...

The invention relates to a method for operating an electrical switching device in an electrical switching system, by which existing drawbacks can be eliminated and safe and protected operation of the electrical switching device outside potentially hazardous areas is made possible. The electrical switching apparatus is operated by an operator through a mobile electronic device, which communicates wirelessly with the electrical switching apparatus. In a first step, the operator reads the first identification means by means of the mobile electronic device to clearly identify the electrical switching device to be operated. In a second step, the operator reads the second identification means through the mobile electronic device to clearly identify the operator's position to be protected. In a third step, the operator is authorized to operate the identified electrical switching device through the mobile electronic device while in the identified operator position.
Description
technical field [0001] The invention relates to a method according to the preamble of claim 1 for operating an electrical switching device in an electrical switching system. Background technique [0002] Depending on the intended user, there is often a requirement for electrical switching systems in power supply networks for a safe and protected operation of the individual switching devices in order to prevent the operator from being exposed to potentially dangerous states during the switching process. The electrical switching apparatus may be, for example, a circuit breaker, a shut-off switch, a grounding switch, a circuit breaker, and / or a transformer. [0003] For example in air insulated switchgear systems there is a potential hazard due to the possibility of arcing and thus the risk of injury to the operator. Manual errors can be limited by safety mechanisms, while arcs can be detected and reduced as part of arc protection measures. However, there are still risks. ...
