A vacuum switch with an elongated cartridge comprising a cylindrical housing sealed by two end plates. Inside the cylindrical housing there are two arcing contacts, one stationary and one movable. The stationary contact is securedly affixed to one of the end plates, whereas the other movable contact is mounted to axially slide inside the cartridge. At least two portions of turn are mounted in parallel. Each portion has a first end electrically connected to one of the arcing contacts and a second end electrically connected to the current input strip of the contact. The first and second ends of each portion of turn are electrically connected by a branch-off designed to disperse a part of the main current trough the potions of turn during breaking.

Vacuum electrical switch or circuit breaker

A vacuum switch has an elongated vacuum cartridge with a cylindrical enclosure blanked off by two end-plates, in which there are housed two arcing contacts respectively stationary and movable, and a coil designed to produce an axial magnetic field in the arc formation zone. The coil has one end arranged as a current conducting strip and an end electrically connected to one of the above-mentioned arcing contacts. The two ends of the coil are superposed and electrically connected, and a branch-off means, such as for example a magnetic circuit, is fitted between these two ends to branch off a part of the main current through the coil during breaking in order to create the axial magnetic field.

Vacuum electrical switch

An elongated vacuum cartridge having a cylindrical enclosure blanked off by two end-plates and housing a stationary arcing contact securedly united to one of the end-plates and a movable arcing contact mounted axially and slidingly inside the cartridge thereby providing a closed position and a separated position of the arcing contacts. An axial magnetic field in the arc formation zone is provided by a horizontal component of arcing current having an inclined trajectory with resect to the plane of the contact surfaces of the arcing contacts, the inclined trajectory being provided by angularly offset and alternating conductive and non-conductive sectors on the ends of each of the arcing contacts.

Electrical vacuum switch

A medium voltage circuit breaker and switch having first and second stationary contacts, a mobile conducting bridge equipped with first and second movable contacts, an operating mechanism coupled to said bridge. The switch further having a vacuum cartridge containing a third stationary contacts electrically connected to the second stationary contacts, a third movable contact electrically connected to said bridge, and mechanically coupled to said operating mechanism, and sequencing means designed to establish the opening and closing sequences of the first, second, and third contacts cooperating with the operating means so that in the course of opening or closing operations of the switch, the third stationary and movable contacts close momentarily to switch the arc associated with the first stationary and movable contacts or with the second stationary and movable contacts.
