-15. (canceled)
An electric device comprising:
- an arc quenching device,
- an arc fault rated cabinet rated to resist an electric arc or short circuit, and
- an elastic support structure configured to absorb energy based on electrodynamic forces in an arc fault event or a short circuit event.
An electric system comprising:
- a plurality of electric devices,
- a common power source, each electric device being electrically coupled to the common power source,
- wherein at least one electric device comprises
- an arc quenching device,
- an arc fault rated cabinet rated to resist an electric arc or short circuit, and
- an elastic support structure configured to absorb energy based on electrodynamic forces in an arc fault event or a short circuit event.
A method of calculating elasticity of an elastic beam configured to absorb energy of electrodynamic forces, the method comprising:
- determining energy of electrodynamic forces based on current and frequency of the current, and
- calculating a length and cross section of the elastic beam such that the elastic beam absorbs the energy of the electrodynamic forces by elastic deformation.
