Definitions
- Locking device for a switchgear The invention relates to a locking device for a switchgear.
- a switchgear for example, a multi-phase medium voltage switchgear with a disconnector and a grounding switch to lock the operation of these switches such that when actuated earthing switch, the disconnector is locked and thus protected against actuation and vice versa ,
- Object of the present invention is to provide a locking device for a switchgear, which allows a simple way locking of several switching devices.
- a locking device for a switchgear which switchgear comprises a first, a second and a third switch and each associated with a switch first, second and third drive shaft
- which locking device comprises a main locking slide between a first, a second and a third locking position is movable, wherein in the first locking position actuating openings for the second and the third drive shaft are blocked and a circuit breaker locking slide is released, in a second locking position, the actuating opening for the second drive shaft is released and the circuit breaker locking slide and the actuating opening for the third drive shaft locked are gelt, and in a third locking position, the actuating opening for the third drive shaft is released and the circuit breaker locking slide and the actuating opening for the second drive shaft are locked.
- the main locking slide is held by means of spring elements in the first locking position, wherein an actuating lever for manual displacement of the main locking slide is provided from the first to the second or in the third locking position.
- a shift or actuation of the main locking slide is in a simple manner allows, in particular by the spring elements a rest position as the first locking position of the main locking slide is defined and formed, from which by means of the actuating lever of the main locking slide can be deflected in a simple manner, so in the second or in the third locking position of the main locking slide, in each case the second or the third drive shaft can be actuated, the other switching devices or drive shafts simultaneously being actuated via the main locking slide. are locked and thus protected against accidental / unforeseen use or unwanted switching operations.
- Figure 1 is a perspective view of a locking device according to the invention.
- Figure 2 is a sectional view through an inventive
- FIG. 1 shows a perspective view of a locking device 1 for a switchgear, which switchgear not shown figuratively has a first switch in the form of a circuit breaker, a second switch in the form of a circuit breaker and a third switch in the form of a grounding switch.
- the first switch is coupled to a power switch drive shaft 2 for initiating drive movement in the first switch
- the second switch is mechanically coupled to a disconnect switch drive shaft 3
- the third switch is mechanically coupled to a grounding switch drive shaft 4 also for initiating drive motions in the first Disconnector or the earthing switch are formed.
- the switch shafts 2, 3 and 4 are each mechanically connected to the locking device 1, wherein the locking device 1 has a locking support 5, which NEN an operating lever 6 for a figured in Fig. 1 main locking slide and a Er- tion switch actuation opening 7 and a Isolator switch opening 8 and a circuit breaker lock slide 9 has.
- the earthing switch operating opening 7 and the breaker switch operating opening 8 are provided in the locking device 1 to be able to actuate the third switch or the second switch by means of an operating tool upon corresponding actuation of the main locking slide via the earthing switch actuation opening 7 or the disconnecting switch actuation opening 8.
- FIG. 2 shows a sectional view through the locking device 1 according to the invention, wherein the locking support 5 is shown in dashed lines in Figure 2 in Figure 2, as well as the Erdungsschalterbetxistsö réelle 7 and the Trennschalterbetxistsö réelle 8.
- Figure 2 shows the main locking slide 10 in a spring elements 11 and 12 held Rest position as the first locking position in which the Erdungsschalterbetxistsö réelle 7 and the
- Isolator operating opening 8 is locked by the main locking slide 10 and thus not released or accessible, so that an operation of earthing switch and disconnector is not possible.
- the circuit breaker lock slide 9 is released, so that the circuit breaker between a switch-on and a switch-off by means of the drive shaft is movable and in particular not locked.
- the circuit breaker locking slide 9 is moved down in Figure 2 and locks the operating lever 6 against movement, so that when the circuit breaker actuation of the actuating lever 6 and thus a displacement of the main locking slide 10 in a second or third locking position in which the earthing switch operating opening 7 or the disconnector operating opening 8 are released, locked and thus prevented.
- the circuit breaker is in its off position, the operating lever 6 through the Circuit breaker lock slide 9 is no longer locked or blocked, so that via the operating lever 6 of the main locking slide 10 is manually convertible to a second or a third locking position, so that in the second locking position the disconnector switch opening 8 is released or in the third locking position the earthing switch operating opening 7 is released to operate the respective switch by means of a tool can.
- the main lock slider 10 has thereto first and second operation openings 13 and 14, wherein the first operation opening 13 is congruent with the disconnector operation opening 8 in the second locking position so that an operation tool is inserted through the disconnector operation opening and the first operation opening 13 for operating the disconnector can, and the second operating opening 14 in the third locking position with the Erdungsschalterbetutzutz 7 is congruent, so that a tool through the Erdungsschalterbet2011 Trentsöff- opening 7 and the second operating opening 14 can be inserted to operate the earthing switch.
- a circuit breaker stop 15 and a grounding switch stop 16 are provided for the earthing switch and the disconnecting switch on the main locking slide 10, which are arranged in dashed lines in a corresponding disconnecting switch slot 17 or earthing switch slot 18 of the disconnecting switch driving shaft 3 or the earthing switch driving shaft 4 Control discs intervene when the respective switch in its off position Located, so that a switching operation is possible, or abuts this respective control disc when the switch is in its closed position in which the respective slot is rotated by 180 ° and an intervention of the disconnect switch stop 15 in the disconnector switch slot 17 and the earthing switch stop 16 in the earthing switch slot 18 is not possible.
