摘要： A non-electrical device (40) includes first and second half-housings which are produced in a plastic material, are joined fixedly to one another, define an axis along which a passage for an electrical conductor passes through the first and second half-housings, and delimit between them an internal volume, which is separated from the passage and which surrounds the passage all around the axis. The first half-housing incorporates, by moulding, mechanical reinforcing elements which extend substantially parallel to the axis in the internal volume until they are in contact with the second half-housing.

摘要： The present invention provides an arc extinguishing structure for direct current circuit breaker, which comprises an arc extinguishing chamber (3) installed on a second casing (2), with a lateral opening (30) which opens towards the first casing (1); a gas generating hood (4) installed at a lower part inside the arc extinguishing chamber (3) and comprising two gas generating plates (41, 42) that are disposed opposite to each other, with a shield plate (43) disposed opposite to the lateral opening (30) and adjacent the second casing (2); a movable contactor (5) and a stationary contactor (6) installed inside an internal installation space (10), with the disconnecting portion between the movable contactor (5) and the stationary contactor (6) being located inside an accommodation space (40) and close to the shield plate (43), so that when the movable contactor (5) becomes disconnected from the stationary contactor (6) and an electric arc is produced, the electric arc triggers the gas generating plates (41, 42) and the shield plate (43) to generate a lot of gas which pushes the electric arc to move in a direction away from the shield plate (43); a plurality of arc extinguishing grid-plates (7) installed at an upper part inside the arc extinguishing chamber (3), having lower slots (71) which are open towards the accommodation space (40) and have a size that gradually decreases along a direction from the second casing (2) to the first casing (1), so that the electric arc during its moving process is continuously blocked by the arc extinguishing grid-plates (7) with increasingly smaller sizes of lower slots (71), and as a result, the electric arc cannot come out from the lateral opening (30) of the arc extinguishing chamber (3), but instead can only enter the spaces between the arc extinguishing grid-plates (7) and thus get extinguished as quickly as possible.

摘要： A breaker comprises a static contact, a moving contact, and an arc-extinguishing chamber. A contact surface of an electrical contact of the static contact and an electrical contact of the moving contact and a bottom plane of a base form an acute angle that is located in the first quadrant. The moving contact comprises a conducting rod having a projecting portion, and the electrical contact which is welded on an end surface of the projecting portion in a direction facing the electrical contact of the static contact. A bottom arc-ignition grid plate on the bottom of the arc-extinguishing chamber is arranged lower than the electrical contact of the static contact. A top arc-ignition grid plate on the top of the arc-extinguishing chamber is arranged higher than the maximum position of the electrical contact of the moving contact when the moving contact is opened.

摘要： The present invention relates to a switching device with at least one contact point and an arc blow device associated with the contact point, where the arc blow device comprises at least one blow magnet for generating a magnetic blow field, and where the blow field is of such nature that a switch arc developing when the contact point opens is blown out from the contact point. It is according to the invention provided that the blow field comprises a first magnetic field area and a second magnetic field area arranged adjacent to the first magnetic field area, where the magnetic field lines of the first magnetic field area are oriented in opposite direction to the magnetic field lines of the second magnetic field area, and where the blow field further comprises a transition area which connects the first magnetic field area and the second magnetic field area with each other, where the orientation of the magnetic field lines in the transition area, each starting out from the first magnetic field area and the second magnetic field area, aligns toward the contact point so that the switch arc within the transition area is in dependence of the direction of the current, starting out from the contact point, directed either into the first magnetic field area or into the second magnetic field area and there in both cases blown in the same direction away from the contact point.

摘要： An electric arc extinction chamber comprises a stack of electric arc splitter plates. The splitter plates define an inlet of the extinction chamber that is to be present facing electric contacts, and a back of the extinction chamber. At least one permanent magnet is present inside the extinction chamber in a central zone in the width direction of the extinction chamber and beside the back thereof. The magnet presents magnetization having a non-zero component along an axis extending between the inlet and the back of the extinction chamber.
