Abstract: PROBLEM TO BE SOLVED: To expose an arc to a strong arc-extinguishing gas flow. SOLUTION: An arc chamber 5 is formed between a fixed contact tulip 1 and a sliding tulip 4. An opening and closing pin 3 movable at a connected position is placed in the arc chamber. The opening and closing pin is plugged in an exhaust outlet 9 surrounded by the sliding tulip 4, and in a spray opening 7 surrounded by the contact tulip 1. The spray opening connects the arc chamber 5 to a pressure chamber 6. The arc chamber 5 is surrounded by a circular heating chamber 13. Plural loading materials 10 for an explosive are provided in the pressure chamber 6. The loading materials are mostly converted into arc-extinguishing gas, nitrogen in particular within about 10-30 ms after ignited. In this case, the gas pressure moves the opening and closing pin 3 toward an interruption position. The gas is sprayed to an arc generated between the opening and closing pin 3 and the contact tulip 1 after the spray opening 7 and the exhaust outlet 9 are opened.

Abstract: PROBLEM TO BE SOLVED: To provide a breaker in which energy exhaust, especially pinch pressure is effectively utilized spraying gas to arc. SOLUTION: Pressure chambers 25a, 25b are placed subsequently to an arc compartment 16 divided by burning rings 32a, 32b. The pressure chambers 25a, 25b are severally connected to a heating chamber 18 concentrically surrounding the arc chamber 18, through return passages 28a, 28b having a rotation symmetry to an opening and closing axis and check valves 29a, 29b. A circumferential spraying slit 19 opened toward the arc chamber 16 from a space between the burning rings 32a, 32b is extended from the heating chamber 18. The pressure chambers 25a, 25b are connected to exhaust chambers 30a, 30b through exhaust pipes 34a, 34b. A pressure rise in the pressure chamber by a pinch pressure contributes to generation of a high spraying pressure in the heating room 18 through the return passages 28a, 28b.

Abstract: PROBLEM TO BE SOLVED: To provide a power breaker in which during breaking an insulating nozzle generates gas, which effectively assists the generation of blow-off pressure inside an arc region. SOLUTION: A power breaker includes a contact structure having a plurality of burning-resistant switching pieces. The contact structure includes a fixed switching piece 3, a switching piece 4 movable along a central axis 2, and an insulating nozzle 6 surrounding the switching pieces 3. 4 concentrically. The insulating nozzle 6 has a constricted part 7 and is manufactured from a burning-resistant synthetic resin. The insulating nozzle 6 is so formed that a burning groove 10 formed extends perpendicular to the direction of electric field load.

Abstract: The circuit breaker has a contact arrangement provided with switch members which cannot be burned away. The contact arrangement has a stationary switch member (3) and a switch member (4) which is movable along a central axis (2). It also has an insulating sleeve (6) which concentrically surrounds the switch members (3,4). The insulating sleeve(6) has a narrowed portion (7). The insulating sleeve (6) is structured such that resulting burn out channels (10) run perpendicular to the direction of the electric field force. The plastic is preferably an aliphatic polymer or an aromatic polymer. The aliphatic polymer and/or the aromatic polymer may be a polyamide or polyimide or polysulphate or polyphenylsulphate or a similar polymer or mixture of these.

Abstract: The arc extinguishing chamber has a pair of electrical power connections (1,2) and in between are switching contacts that are in the form of fixed spring contacts (3) and an axially movable pin (4). The chamber has a toroidal shaped heating space (7) formed between a cylindrical isolator (8) and an isolating nozzle stage (9). A ring shaped channel is created (10) between the parts. An arc extinguishing material is formed as a coating and during an arc generating switching operation, when the contacts separate, extinguishing gas is produced. The material has a microcapsular structure that releases that gas.
