摘要： A conduction breaking device includes a conductive body arranged between a pair of devices in an electric circuit, a gas generator, which is arranged away from the conductive body and generates gas, and a cutting member, which is arranged between the conductive body and the gas generator. The cutting member is moved due to gas from the gas generator to cut the conductive body, divides the conductive body into a first cut piece and a second cut piece, which have cut ends separated from each other, and breaks the conduction between the devices. The conduction breaking device includes an arc-extinguishing chamber. In the arc-extinguishing chamber, the conductive body is cut by the cutting member and an arc occurring between the cut end of the first cut piece and the cut end of the second cut piece is extinguished.

摘要： An electric switchgear includes an interrupter unit having a first connecting line and a second connecting line. The interrupter unit is disposed inside a fluid-tight encapsulating housing that is filled with an electrically insulating fluid. The interrupter unit is further surrounded by a shielding housing in at least some sections. The first connecting line has a flow channel for the fluid. A first outlet opening of the flow channel leads to the shielding housing and a second outlet opening leads to the exterior of the shielding housing.

摘要： A high-voltage switch has a metal container filled with insulating gas, and a quenching chamber installed in the container. The quenching chamber contains a housing which is aligned along an axis, an arcing contact arrangement which is held in the housing, an exhaust volume which is bounded by the housing, and an outlet channel which is passed through the wall of the housing for exhaust gases. The outlet channel opens with a mouth section which is aligned predominantly axially into the container. The mouth section is bounded on the inside by a tubular section of the housing and on the outside by a tubular housing attachment which surrounds the housing section at a distance from it. An electrically shielded edge which is passed in an annular shape around the axis is arranged on one end face of the housing attachment on which edge a flow, which emerges from the outlet channel of the exhaust gases is detached from the housing attachment.

摘要： A circuit interrupter comprises a pressure chamber and an arc extinguishing chamber containing an arc extinguishing fluid and a pair of separable contacts. The pressure chamber includes a separation chamber including a guide member or a check valve for supplying a high pressure fluid derived from an electric arc generated between the contacts to the pressure chamber. The high pressure fluid supplied from the high pressure chamber extinguishes the arc between the contacts. The guide member or the separation chambers alleviate mixing of the hot high pressure fluid with the cold high pressure fluid in the pressure chamber, providing the circuit interrupter with an improved arc extinguishing capability.
