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: The device for switching electric current comprises a compressed gas switch, at least one vacuum switch (14) and two terminals (2, 3). In this switching device, a first consumable contact (10) of the compressed gas switch is electrically connected to a fixed electrode (15) of the vacuum switch (14), a second consumable contact (7) of the compressed gas switch is connected to a first (2) of the two terminals (2, 3) and a movable electrode (16) of the vacuum switch (14) is connected to a second (3) of the two terminals (2, 3) to form a quenching circuit. The two electrodes (15, 16) of the vacuum switch (14) can be separated without the use of the drive (5) and a contact pressure is applied to them which prevents the electrodes (15, 16) from breaking below a threshold value of the current to be switched off. On switch-off, the current to be interrupted is switched over from a rated current circuit containing two rated current contacts (8, 11) of the compressed gas switch to the parallel quenching circuit. The vacuum switch (14) now in the quenching circuit breaks only if the current to be switched off exceeds the aforementioned threshold. As the vacuum switch (14) does not conduct the rated current and, unlike the compressed gas switch, is involved only in a few break operations, it can be of substantially lighter construction than a vacuum switch carrying the rated current and is actuated in every switching operation.
