Definitions
- the invention relates to a switching device designed as a vacuum contactor with a contact fixed to the housing (fixed contact) and a contact (movable bearing) which can be displaced to produce a current-conducting connection, with the further features of the preamble of patent claim 1.
- Vacuum contactors are known as prior art, in which a sleeve is attached to the floating bearing and slides on a pin fixed to the housing. Vacuum contactors are also known in which a guide ring is provided on the vacuum tube.
- the guide ring can be arranged on the fixed or floating bearing side.
- the invention has for its object to offer a vacuum contactor with a fail-safe loose bearing guide.
- the object is achieved by the features of the characterizing part of patent claim 1 in conjunction with the features of the preamble.
- Advantageous embodiments are described in subclaims 2 to 11.
- Contactors are switching devices and are e.g. used to switch motors.
- the contactors can be designed as air protection or as vacuum contactors.
- the vacuum switching device according to the invention - in short vacuum protection - for opening and closing circuits has a floating bearing with at least one guide element which is guided in a groove (recess) in the housing of the vacuum protection and is displaced when the floating bearing is actuated.
- the guide element can be attached to a spring support of a compression spring for generating additional contact contact pressure of the floating bearing on the fixed contact, as a result of which the spring support has a double function.
- the guide element is attached to a ring element arranged adjacent to the bellows element and thus close to the contact point of the floating bearing, a particularly secure floating bearing guidance is achieved.
- e.g. opposite guide elements can be provided on the spring support and / or on a ring element.
- a simplified structural design of the vacuum contactor is achieved if the ring element, in addition to the attached guide element, also has an indicator for indicating the displacement position of the floating bearing (closed / opened) and / or a projection for positioning an angular element for attaching a current band to the floating bearing.
- Groove (guide groove) coordinated to produce a positive connection and their cross-section can be adapted to the required load profile and e.g. also be triangular or semicircular.
- groove is to be understood as a recess of any kind.
- the groove or grooves for receiving the guide element or the guide elements can, for example, be milled or otherwise produced by means of shaping, material-removing or material-compacting manufacturing processes. gen / recesses in the housing of the vacuum contactor.
- the groove for receiving the guide element is formed by interaction of the (placed) cover of the housing with the lower part of the housing, so that when the housing is open and the cover is removed, the floating bearing is user-friendly, e.g. can be removed from the housing (from above) for repair or replacement of the vacuum tube.
- FIG. 1 shows an overall perspective view of a vacuum contactor (tube assembly, current path) without a housing
- FIG. 2 shows a longitudinal section through the vacuum contactor according to FIG. 1 with the surrounding housing and
- FIG. 3 shows a section B-B according to FIG. 2.
- the individual phases are switched on and off separately and the associated vacuum tubes used for this purpose are usually located in housings with adjacent housing chambers for accommodating the individual vacuum tubes.
- FIG. 1 An individual tube assembly according to FIG. 1 is accommodated in each housing chamber.
- the tube assembly according to FIG. 1 has a fixed bearing 33 with attached fixed contact 1 according to FIG. 2.
- the tube 15 with bellows element 3 is followed by the ring element 9 with indicator 10, the angle element 28 and the compression spring 8, which is received in the spring support 7.
- the lever 23 according to FIG. 2 engages between the spring support 7 and the lever supports 17 (not shown in FIG. 1).
- the vacuum contactor according to FIG. 1 is activated, the floating bearing 2 is displaced in the tube 15 with compression of the bellows element 3 and the compression spring 8, as a result of which the guide elements 6a, 6b and 6c in the corresponding grooves 5a and 5b (longitudinal grooves) of the adjacent housing walls 31 and 32 are moved and guided (see FIG. 2 and FIG. 3).
- Guide element 6d is located opposite guide element 6a (see FIG. 3) and cannot be seen in FIG. 1.
- the fixed contact 1 is located on the fixed bearing 33 of the vacuum contactor, which is conductively connected via the fixed bearing element 18 to the connecting bar 19 for the introduction of current.
- Angle element 28 attached to the bolt 16.
- the lever 23 of the lever element 29 is located between the lever support 17 and the spring support 7, which is rotatably received on the bearing element 24 and, when the contact carrier 25 is actuated in the displacement direction 26, the vacuum contactor closes by displacing the bolt 16 of the floating bearing 2 to the fixed contact 1 causes.
- the angle element 28 is connected to the connecting bar 27 via the current strip 14. When the vacuum contactor is closed, there is a current connection between the connecting rail 19 and the connecting rail 27 via the fixed contact 1 and the floating bearing 2.
- the guidance of the floating bearing 2 is achieved by the guide elements 6a to 6d, which are essentially cuboid.
- the guide elements 6a and 6d are attached to a ring element 9 surrounding the bolt 16, which ches has a projection 34 which serves to position the angle element 28 and the compression spring 8.
- the guide elements 6b and 6c are located on the spring support 7.
- the tube assembly is accommodated in a housing 4 with a removable cover 11.
- the lid 11 has a recess 30 through which the indicator 10 of the ring element 9 is visible.
- Cover 11 can recognize the switching state of the vacuum contactor (open / closed) via the position of the indicator 10 in the recess 30.
- FIG 3 shows the arrangement of the tube assembly in an inner chamber of the housing 4 between the housing walls 31 and 32.
- the vacuum contactor is covered by the cover 11 from above.
- the grooves 5a and 5b can also be formed by recesses which are completely in the housing walls 31 and 32 or a recess on the cover 11 which is provided with a
- FIG 3 also shows the contact carrier 25 with the lever element 29 received.
- the contact carrier 25 is displaced in the direction of displacement 26 via a magnet system (not shown).
- the guide elements 6b and 6c are guided in the associated grooves 5 (or groove areas) with greater play than the guide elements 6a and 6d in their assigned grooves 5 (or groove areas) in order to slightly tilt the bolt 16 when closing and opening the Floating bearing 2 because of the rotary movement of the lever 23 to enable the bearing element 24 (not shown).
