摘要： A simplified construction of a gas-insulated high-power circuit breaker with a saving of components is achieved by at least one hole and at least one leaf spring, which is fastened on one side and is elastically bendable in dependence upon the pressure of the insulating gas in the compression volume, being formed in a valve plate of the valve. The bendable spring closes off the hole when the circuit breaker closes and opens it when the circuit breaker opens as soon as the pressure of the compressed insulating gas in the compression volume exceeds the value of the gas pressure in the low-pressure chamber by at least two bar.

摘要： A self-blowout circuit breaker is disclosed which includes contacts for connecting or disconnecting a circuit, a heating volume, a compression volume and an exhaust volume. The compression volume can be connected to the heating volume by at least one first valve, which heating volume is in turn connected to an arc zone. Upon the disconnection of the circuit, while a first arcing contact is being disconnected from an associated second arcing contact, an arc is produced between the two arcing contacts in the arc zone. The compression volume is separated from the exhaust volume by a combined filling and overpressure valve which is formed as at least one plate, and has at least one tab which is formed in the plate.

摘要： A valley section is provided between a high-voltage arc contact and a high-voltage main contact. Because of the presence of the valley section, resistance between contacts is reduced while a moving arc contact makes contact with the high-voltage arc contact and then slides up to making contact with the high-voltage main contact.

摘要： The invention provides a gas insulated switchgear, and a method for detecting arc damage in a part used in a gas insulated switchgear, which detect directly when an electric contact or a peripheral part reaches an initially set wear limit. An insulating nozzle of a circuit breaker contains a marking substance that releases a gaseous substance inside a circuit breaker gas container as a result of wear by an arc. For ensuring heat resistance and insulation properties, the insulating nozzle is ordinarily formed of a fluororesin, but in the present invention, it is formed of the ordinarily used fluororesin having uniformly mixed therein, as the marking substance, a chlorine-containing resin which has excellent heat resistance and insulation properties such as polyvinylidene chloride.

摘要： A switching chamber is intended for a gas-insulated high-voltage switch and contains a contact arrangement with two arcing contacts, which move relative to one another along an axis, with an insulating nozzle, an insulating auxiliary nozzle, a heating volume and a heating channel. The heating channel is routed partially axially between the insulating nozzle and the insulating auxiliary nozzle and connects an arcing zone to the heating volume. A section of the heating channel which opens into the heating volume is inclined inward with respect to the axis. Hot gas which is formed when a short-circuit current is disconnected in the arcing zone therefore flows with a velocity component directed inward into the heating volume, and can penetrate deeply into the heating volume in areas close to the axis. The quality of a quenching gas which is formed in the heating volume from the hot gas and cold gas which is already present, with this quenching gas being used to blow a switching arc which has been struck in the arcing zone during disconnection, can thus be improved.
摘要翻译：开关室用于气体绝缘高压开关，并且包含具有两个电弧触点的接触装置，两个电弧触点沿着轴线相对于彼此移动，具有绝缘喷嘴，绝缘辅助喷嘴，加热体积和加热渠道。加热通道在绝缘喷嘴和绝缘辅助喷嘴之间部分地轴向延伸，并将电弧区连接到加热体积。进入加热容积的加热通道的一部分相对于轴线向内倾斜。因此，在电弧区中断开短路电流时形成的热气体以向内进入加热容积的速度分量流动，并能够深入到靠近轴线的区域的加热容积内。从已经存在的热气体和冷气体的加热容积中形成的淬火气体的质量，由于这种淬火气体用于吹出在断开期间已经在起弧区域中撞击的开关电弧，因此可以是改进。

摘要： The heavy-duty circuit breaker can be filled with a quenching gas and contains a first moveable arcing contact piece and a second moveable arcing contact piece as well as a drive for driving the first arcing contact piece and an auxiliary drive for driving the second arcing contact piece. An arc may burn between the arcing contact pieces. The heavy-duty circuit breaker has a heating chamber for temporarily storing quenching gas heated by the arc and an insulating nozzle, which has a throat for guiding a quenching gas flow, which throat is connected to the heating chamber by means of a channel. The throat can be blocked at least partially by one of the two arcing contact pieces, which is referred to as the blocking contact piece. The auxiliary drive is designed such that, during an opening operation, a movement direction reversal of the second arcing contact piece from a movement in opposite directions to a movement in the same direction of the two arcing contact pieces takes place, if the throat is no longer at least partially blocked by the blocking contact piece. Advantageously, the gear is a gear which is driven by the drive.

摘要： A gas-blast load-break switch comprises a pressure storage chamber for storing pressure of arc-extinguishing gas with arc energy generated by the disconnection between contacts, and a suction chamber including a piston which is moved in connection with the cut-off movement of the movable contact. A gas flowing device is provided such that the pressure raised by the arc energy is stored in the pressure storage chamber before communicating the pressure storage chamber and the suction chamber and a gas chamber formed on the opposite side of the piston from the suction chamber. The volume of the gas chamber is greater than that of the pressure storage chamber and the suction chamber, and the distance of piston movement in the suction chamber is longer than the contact length when the movable contact is thrown into the fixed contact.

摘要： In a puffer type gas-blast circuit breaker, a fixed arc contact (1) which has a hollow (1a) therein, with at least one vent (1b) on an end part thereof, stores a high pressure insulation gas which is heated and expanded by an arc formed between the fixed arc contact (1) and a moving arc contact (6) and is pressurized by passing through a nozzle (8) in an operation breaking a current, and after breaking of the current, the insulation gas stored in the hollow (1a) flows out of the vent (1b) and expands around the end part of the fixed arc contact; whereby a dielectric strength of the space around the end of the fixed arc contact (1) is strengthened so that reignition between the fixed arc contact (1) and the moving arc contact (6) is avoided.
