Abstract
An electrical switching device is disclosed, including an arc extinguishing apparatus with an extinguishing chamber, a blow-out channel connected to the extinguishing chamber for blowing out plasma and/or gas produced in the extinguishing chamber from the electrical switching device and a terminal apparatus for connecting an electrical conductor to the electrical switching device, the terminal apparatus including a metal part which is electrically conductively connected at a first end to the electrical switching device and which, at its second end, includes a terminal fixing for connecting the electrical conductor, with which the metal part of the terminal apparatus is guidable out of the electrical switching device through the blow-out channel.
Claims17
An electrical switching device, comprising:
- an arc extinguishing apparatus including an extinguishing chamber;
- a blow-out channel connected to the extinguishing chamber, configured to blow out, through an opening of the blow-out channel, at least one of plasma and gas produced in the extinguishing chamber from the electrical switching device;
- and
- a terminal apparatus, configured to connect an electrical conductor to the electrical switching device, including a metal part electrically conductively connected at a first end to the electrical switching device and, at a second end, a terminal fixing configured to connect the electrical conductor, the metal part being guidable through the blow-out channel so that a portion of the metal part including the second end protrudes beyond a rear side of the electrical switching device to expose the portion to external surroundings of the electrical switching device, wherein,
- the metal part is shrouded at least in the region passing through the blow-out channel by an insulation element such that the insulation element surrounds an entire portion of the metal part that is arranged in the blow-out channel, and
- the insulation element surrounds a part of the portion of the metal part protruding beyond the rear side of the electrical switching device.
