Embodiment Construction

[0027] In the remainder of the specification, the term "substantially equal to" defines equivalences within ±10%, or where the term refers to angles, ±10% 0 equivalence relationship.

[0028] exist figure 1 and 2 Among them, the contactor 10 includes at least one vacuum interrupter 12 , and each vacuum interrupter 12 includes a fixed contact 14 , a movable contact 16 and a rod 18 fixed to the movable contact 16 . Rod 18 is movable between a closed position of vacuum interrupter 12 in which movable contact 16 abuts fixed contact 14 ( figure 1 ), the movable contact 16 is separated from the fixed contact 14 in the open position ( figure 2 ).

Abstract

The invention relates to a contactor (10) comprising at least one vacuum interrupter (12). Each of the vacuum interrupters comprises a fixed contact (14), a movable contact (16), and at least one rod (18) fixedly disposed on the movable contact (16), a first motion member (20). The rod (18) can move between the closed position and the opened position of the vacuum interrupter (12). The movable contact (16) on the closed position can abut against the fixed contact (14), and the movable contact (16) on the opened position can be separated from the fixed contact (14). The first motion member (20) can be used to move each rod (18) from the closed position to the opened position along the motion direction X. The contactor (10) also comprises an adjusting member (30), which can be used to adjust the speed of each rod from the closed position to the opened position during the whole moving period.

Description

technical field [0001] The invention relates to a contactor comprising at least one vacuum interrupter and a first moving member; each vacuum interrupter comprising a fixed contact, a movable contact and a rod fixed to the movable contact, The lever is movable between a closed position of the vacuum interrupter, in which the movable contact abuts the fixed contact, and an open position of the vacuum interrupter, in which the movable contact is movable. The movable contact is separated from the fixed contact; the first movement member is used to move each lever in the direction of movement from said closed position towards the open position. [0002] The invention also relates to a railway contactor comprising one or more vacuum interrupters (also called vacuum tubes). These vacuum tubes are used in particular in the railway sector, for example installed in high voltage contactors which are arranged on top of railway vehicles between pantographs and transformers.
