摘要： The invention relates to a coated arc splitter made of a ferromagnetic material for use in an arcing chamber. The invention provides that the arc splitter has a layer made of a composite material consisting of at least two constituents of which the first constituent is electrically conductive, has a melting point which does not exceed that of the ferromagnetic material, and has a vaporization point which does not exceed that of the ferromagnetic material, and of which the second component has a melting point higher than that of the first constituent, and has a vaporization point higher than that of the first constituent.

摘要： An electric high-voltage power switch has two contacts (1, 2) and at least one gas outlet (17) for quenching gas heated by the arc and a cooling device (12) for cooling the quenching gas consisting of a metal body (12) with through apertures (18) arranged in the flow path of the quenching gas. An insulating component (13, 14) impermeable to the quenching gas, is fitted in the gas outlet (17) in front of the metal body (12) viewed from the contacts (1, 2) and consists of a material (PTFE) releasing a quenching gas at high temperatures. Said insulating component (13, 14) is far enough away from the metal body (12) for the quenching gas to be able to pass through the aperture (18) substantially over the entire surface of the metal body (12).

摘要： Es wird ein Werkstoff für elektrische Kontakte mit Licht bogenlöschung beschrieben, welcher aus einer irreversibel ausgehärteten Polymer-Formmasse (Duromer) besteht, welche mit 5 bis 20 Vol.-% eines Metallpulvers und wahlweise bis zu 40 Vol.-% eines weiteren anorganischen, elektrisch nicht leitenden Pulvers gefüllt ist.
Als Duromer wird ein solches verwendet, welches sich ohne Auftreten einer flüssigen Phase aushärten läßt.

摘要： Disclosed is a gas circuit breaker, including: a first contact portion including a first arc inducement contact; a second contact portion including a second arc inducement contact, which is formed so as to be relatively movable with respect to the first arc inducement contact so as to be in a state of being in contact with the first arc inducement contact or a state of being separated from the first arc inducement contact; a gas chamber configured to store extinguishing gas for extinguishing arc generated between the first arc inducement contact and the second arc inducement contact when the first arc inducement contact is separated from the second arc inducement contact; a gas injection nozzle formed of an electric insulating material and configured to form an injection passage of extinguishing gas; and an arc length limiting contact disposed so as to be spaced apart from the second arc inducement contact, and configured so as to be moved together with the second arc inducement contact when the second arc inducement contact moves, and configured so that an end of the arc length limiting contact at the second arc inducement contact side is located at a point beyond an end of the first arc inducement contact when the first arc inducement contact is farthest from the second arc inducement contact
