Abstract
A system for short-circuiting or grounding low-voltage and/or medium-voltage installations. The system includes at least one fault detection unit for detecting an arc and at least one signal-processing unit for processing signals from the at least one fault detection unit. The signal-processing unit is or can be connected to the fault detection unit for signal transmission. The system further includes at least one control unit which is or can be connected to the signal-processing unit for signal transmission, an electrical energy storage device in or on the control unit, and at least one fast-switching switching element having a mechanical energy store.
Claims19
A system for short-circuiting or grounding a voltage installation, the system comprising:
- at least one fault detection unit for detecting an arc;
- at least one signal processing unit for processing signals of the at least one fault detection unit, said signal processing unit being connected to, or configured for connection to, said fault detection unit for signal transmission;
- at least one control unit connected to, or configured for connection to, said signal processing unit for signal transmission, and an electrical energy storage apparatus in or on said at least one control unit;
- at least one fast-switching switching element having a mechanical energy store, said fast-switching element being connected to, or configured for connection to, said control unit for transferring electrical triggering energy from said electrical energy storage apparatus, wherein the electrical triggering energy is used, or usable, to effect a triggering of a switching operation of said at least one fast-switching switching element, wherein said mechanical energy store is effective to perform the switching operation with the drive energy stored in said mechanical energy store;
- and
- said control unit and said electrical energy storage apparatus being disposed in a voltage compartment, whereas said fast-switching switching element and said mechanical energy store are disposed in a region of a busbar and/or a switchgear to be protected.
