Abstract

An automatic switchgear apparatus comprising a support, at least one line terminal, at least one load terminal, said line and load terminals being supported in predetermined relation to said support, a supported arc initiation chamber in predetermined relation to said support and having a lower wall and surrounding side walls, an arc extinguishing chamber connected to said arc initiation chamber by a passage and comprising a pair of opposite side walls, at least two relatively contacts movable supported next to said passage, characterized in that said walls of said arc initiation chamber and said walls of said arc extinguishing chamber are provided with, at least, parts of their interior surfaces made of a material having the characteristic of generating gas under the influence of an electric arc to form a gas that has hydr free oxygen as a substantial constituent, said carbon gas comprising substantially only in combined form, an arrangement for moving said contacts relative to each other between closed and open positions to create an arc in a predetermined location adjacent to said passage, said inner surfaces being said walls of said arc initiation chamber very close to said position of creation of the arc and said lower wall of said arc initiation chamber being substantially closed, whereby said material of said interior surfaces of said side walls of the arc chamber. initiation of the arc generates gas thanks to said arc, filling said arc initiation chamber with a high pressure gas, said gas being unable to substantially escape said arc initiation chamber except to said arc extinguishing chamber by means of said passage and propelling said arch taking it to an elongated state.
