Abstract
The utility model relates to a vacuum switch for medium voltage switchgear equipments, which comprises at least a pole unit (2) with a vacuum switch tube (7), a driving unit (3) positioned on a moving contact (6) for introducing a switch movement to the vacuum switch tube (7), and a wall section (4), wherein a driving lever (5) extends to the moving contact (6) of the vacuum switch tube (7) from the driving unit (3) through the wall section (4). The utility model is characterized in that an airtight type seal is formed by a thin-film bellows (13) between the driving lever (5) and the wall section (4). The vacuum switch can be easily used in gas insulated medium voltage switchgear equipments with the airtight type seal formed between the driving lever and the wall section.
Description
Technical field
The utility model relates to a kind of vacuum switch that is used for medium voltage switchgear equipment, it has at least one pole unit with vacuum switch tube, one and is used for a kind of switch motion is incorporated into driver element and a wall portion section on the moving contact of vacuum switch tube, wherein, drive rod passes described wall portion section from driver element and extends to the moving contact of described vacuum switch tube.
Background technology
This vacuum switch for example is 3 TL, the 71 type switching devices of Siemens Company.This switch comprises that a vacuum switch tube and one are used for a kind of switch motion is incorporated into driver element on the moving contact of vacuum switch tube.At this, this driver element is separated by a wall portion section and described vacuum switch tube, and wherein, drive rod passes described wall portion section from driver element and extends to the moving contact direction of described vacuum switch tube.This wall portion section is used for vacuum switch is fixed on the shell of an air-insulated medium voltage switchgear equipment.
The utility model content
The technical problems to be solved in the utility model is that the vacuum switch that this paper is started described type is configured to can be used for gas isolated medium voltage switchgear equipment.
According to the utility model, above-mentioned technical problem can be solved by a kind of vacuum switch that is used for medium voltage switchgear equipment, this vacuum switch has at least one pole unit that has a vacuum switch tube, one and is used for switch motion is incorporated into driver element and a wall portion section on the moving contact of described vacuum switch tube, wherein, drive rod passes described wall portion section from described driver element and extends to the moving contact of described vacuum switch tube, becomes a hermetically sealing by a film bellow-shaped between described drive rod and described wall portion section.
Can easily this vacuum switch be used for gas isolated medium voltage switchgear equipment by this hermetic seal between described drive rod and described wall portion section, because described wall portion section constitutes a closure that is used for described at least one pole unit of this vacuum switch with the outer casing member of described gas isolated medium voltage switchgear equipment, make described at least one pole unit can be placed in the enclosure space of filling with insulating gas.Particularly advantageously form hermetically sealing between described drive rod and the described wall portion section by means of described film bellows, therefore the switch motion of driver element can be guided on the moving contact by described drive rod from this driver element.At this; when for example especially in a vacuum protection switch, needing to carry out a large amount of switching manipulation; described film bellows advantageous particularly; but because have special bearing capacity and flexible and therefore be suitable for flexible hermetically sealing based on its flexible structure that is made of the high-quality steel diaphragm of each punching press, wherein said each high-quality steel diaphragm is by means of interconnecting at inside and outside weld seam.
Description of drawings
By means of embodiment the utility model is elaborated with reference to the accompanying drawings, in the accompanying drawing:
Fig. 1 represents the cross-sectional view of vacuum switch of the present utility model;
Fig. 2 represents the detail view of the wall portion section that intercepts from Fig. 1.
Embodiment
Fig. 1 represents a vacuum switch 1 that has a pole unit 2 and a driver element 3, wherein, pole unit 2 and driver element 3 are separated mutually by a wall portion section 4, wherein, a drive rod 5 passes this wall portion section 4 from a moving contact 6 extensions of driver element 3 to a vacuum switch tube 7 of pole unit 2.In addition, this vacuum switch tube 7 comprises a fixed contact 8, wherein, fixed contact 8 and one first connector 9 conductions link to each other and moving contact 6 links to each other with one second connector, 10 conductions, feasiblely are connected with conduction between second connector 10 by means of described vacuum switch tube 7 may command first connector 9.Described drive rod 5 is constituted as to be used for the motion of a switch of driver element 3 is incorporated on the moving contact 6 of vacuum switch tube 7 and by an insulating part 11 and is electrically connected with moving contact 6 disengagements.Wall portion section 4 has a welding bead 12 and is given on the not shown outer casing member that is welded on a gas-insulated medium voltage switchgear equipment, at this, the outer casing member of this gas isolated medium voltage switchgear equipment constitutes the envelope space of at least one pole unit 2 that is used to hold vacuum switch 1 that can fill insulating gas with described wall portion section 4.Be incorporated in the moving contact 6 for the switch with driver element 3 moves through described wall portion section 4, described drive rod 5 is fixed on the described wall portion section 4 by means of a film bellows 13, make between drive rod 5 and wall portion section 4, to form airtight sealing.Drive rod 5 is connected with driving shaft 16 mechanical types of driver element 3 by a mechanical connector 15 on the end 14 that driver element 3 directions are extended at it.In addition, described wall portion section 4 has and is used for the retaining element 17 and 18 that described at least one pole unit 2 is fixing.From Fig. 1, see and have only a pole unit 2, but self-evidently be, in a multipole vacuum switch, can on each retaining element of described wall portion section 4, fix a plurality of pole units, their each drive rod extend through this wall portion section 4 and with described driving shaft 16 mechanical connections.
Fig. 2 represents to have the detail view of the wall portion section 4 of a through hole 19 that is used for described drive rod 5.Soldering sleeve 20 1 side and section 4 welding of wall portion and opposite side and 13 welding of described film bellows, wherein, this film bellows 13 in addition simultaneously also with 21 welding of a welded flange, this welded flange welds together with described drive rod 5 again.By the switch motion of the driver element 3 of Fig. 1 being incorporated into the flexible through hole at least one pole unit 2 described in Fig. 1 with soldering sleeve 20 and described wall portion section 4 and with 13 welding of film bellows with by described welded flange 21 being formed hermetically sealing thus with described film bellows 13 and with described drive rod 5 welding and forming a kind of being used for.
