摘要： 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.
摘要翻译：用于开关电流的装置包括压缩气体开关，至少一个真空开关（14）和两个端子（2,3）。在该开关装置中，压缩气体开关的第一可消耗接头（10）电连接到真空开关（14）的固定电极（15），压缩气体开关的第二可消耗接头（7）连接到两个端子（2,3）中的第一个（2）和真空开关（14）的可动电极（16）与两个端子（2,3）中的第二个（3）连接以形成淬火电路。真空开关（14）的两个电极（15,16）可以在不使用驱动器（5）的情况下分开，并且向它们施加接触压力，从而防止电极（15,16）断开低于阈值的电流被关闭。在关断时，要被中断的电流从包含压缩气体开关的两个额定电流触点（8,11）的额定电流电路切换到并联淬火电路。现在在淬火回路中的真空开关（14）仅在要关断的电流超过上述阈值时断开。由于真空开关（14）不传导额定电流，并且与压缩气体开关不同，仅涉及少量的断开操作，其结构可以比承载额定电流的真空开关的结构明显更轻，并且每隔开关操作。

摘要： The invention relates to an electric insulator with an insulator body (3) which is mounted between an electric conductor (1) and a grounded fixture (2). The surface of said insulator is at least partially configured as a protective body (6). The material of said protective body has a low relative permittivity as compared to that of the material of the insulator body (3). The protective body (6) prevents an electroconductive particle (12) from directly contacting the surface of the insulator body (3), especially the area of triple points T, and from substantially strengthening the field by the immediate vicinity of the insulating body (3). A gas-insulated system that contains the inventive insulators that are provided with such a protective body has an increased disruptive voltage. The invention provides a means for producing more compact and less expensive gas-insulated systems that have a prolonged service life.

摘要： A high voltage circuit breaker (1) comprising an interruption chamber (2) being filled with an extinguishing agent, wherein said interruption chamber (2) comprises at least two separable arcing contact pieces (12, 13) that are coaxially arranged and an arcing zone (10) in which an electric arc (14) is producible during an interruption process. Said interruption chamber (2) comprises further at least two inlets (15a, 15b) and at least one outlet (20a) located in between two inlets (15a, 15b). The inlets (15a, 15b) and the at least one outlet (20a) are fluidly connected with said arcing zone (10) such that the electric arc (14) is extinguishable in at least three arc interruption zones by means of extinguishing flows (25, 25a, 25b) streaming out of the at least two inlets (15a, 15b) into the arcing zone (10) upon pressurization and introduction of a portion of the extinguishing agent in said arcing zone (10) and leading an amount of said extinguishing flows (25, 25a, 25b) through said outlet out of the arcing zone (10).

摘要： The invention relates to a self-blast circuit breaker wherein the inner contact (3) is provided with a control body (9), running into or against the outer contact (2). The control body (9) forces the arc into an arc zone (10) in the form of a hollow cylinder. A more rapid build-up of pressure is thus achieved with an improved charging of the quenching chamber (5) of the breaker with quenching gas. By means of suitable shaping of the control body (9) the gas flow out of or into the arc zone (10) can be optimised.
