Abstract: A switching apparatus includes one or more electric pole units, each electric pole unit comprising a fixed contact, a movable contact, a first pole terminal, a second pole terminal, and a motion transmission arrangement to reversibly move the movable contact. The motion transmission arrangement includes a conductive motion transmission member coupled to the movable contact. The first pole terminal is in electrical connection to the fixed contact while the second pole terminal includes a first coupling region in electrical connection with a second coupling region of the conductive motion transmission member. Each electric pole unit further includes a shielding element formed by a conductive hollow body and arranged in a relative fixed position with respect to the second pole terminal and the motion transmission member. The shielding element is arranged to at least partially surround the first coupling and the second coupling region.

Abstract: A circuit breaker having a mechanical switch introduced into a main current path, which comprises a fixed contact and a moving contact connected to a movably mounted contact bridge. The circuit breaker comprises a drive, which is in active connection with the contact bridge, and which comprises a first drive unit and a second drive unit. The first drive unit is energized via a control circuit, and the second drive unit is connected in parallel to a resistor element introduced into the main current path. The invention also relates to a motor vehicle.

Abstract: A high voltage electric disconnect switch having a rotatable switch blade in operative arrangement with a rotatable high voltage electrical insulator. A rotating bearing assembly in operative supporting arrangement with a rotatable shaft. The bearing assembly containing corrodible ball bearing assemblies including associated corrodible ball bearing races. The rotatable insulator is operatively mounted to the rotatable shaft. The rotatable shaft has a lower rotatable shaft portion contacting the corrodible ball bearing assemblies housed within a sealed housing of the bearing assembly. An air permeable hydrophobic membrane mounted in a membrane assembly is mounted in an aperture of the housing to eliminate condensing humidity within the housing, thereby preventing corrosion of the corrodible ball bearings and races, freezing water, and lubrication degradation by keeping the surfaces dry to prevent switch failure.

Abstract: A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.

Abstract: A stored energy-type circuit breaker includes a sensor that operates as a full open sensor, and that is used to prevent the circuit breaker from closing in response to either a closing signal or a manual operation. The full open sensor exhibits a first output condition when the moveable contact is in a fully open position and a second output condition when the moveable contact begins to leave the fully open position. An electronic trip unit (ETU) is electrically connected to the sensor and, when in a close break mode, blocks the circuit breaker from closing. The ETU does this by, upon detecting that the sensor is in the second output condition, generating a signal that will cause the breaker's opening spring to return the moveable contact to the fully open position.

Abstract: A switch includes an operating member and three contacts (first, second and third contacts). The operating member displaces between a first and a second positions. A state of the three contacts is switched between a first and a second states by displacement of the operating member. Each contact connects or disconnects a signal line in the first state, and puts, in the second state, the signal line into a state reverse to the first stat. In course of the displacement of the operating member from the first position to the second position, the first contact switches from the first state to the second state, the second contact switches from the first state to the second state after switching of the first contact, and the third contact switches from the second state to the first state at a timing between switching of the first contact and switching of the second contact.
