Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides one to have anti-misoperation function, and prevention earthing misoperation causes the earthing anti-misoperation apparatus that accident occurs.
For achieving the above object, the utility model is by the following technical solutions:
A kind of earthing anti-misoperation apparatus, comprise the locking axostylus axostyle of the panel behind that is located at switch cubicle, described locking axostylus axostyle is provided with pin and handle is dialled in release, described release is dialled vertically stretching out behind described panel from described panel, stir described release and dial moving axially described locking axostylus axostyle, make the end of described locking axostylus axostyle stretch into or exit in described earthing handle hole;
Be located at transducer, electrification display and electromagnet in cabinet, described electromagnet has a push rod, and described transducer is electrically connected with described electrification display, and described electrification display is electrically connected with described electromagnet;
When described transducer detects when charged, described electromagnet makes described push rod stretch out cabinet forward and gear is dialled front in described release, and when described transducer does not detect when charged, described electromagnet makes to contract and return cabinet after described push rod.
The utility model also comprises the parallel two relative holders that are arranged on described panel behind, on described holder, respectively have the relative sliding eye in position, the two ends of described locking axostylus axostyle are enclosed within on described sliding eye actively, and described pin and described release are dialled between described two holders.
The position of described locking axostylus axostyle between described two holders is also arranged with spring, and described spring one end is against wherein on a holder, and the other end is against described release and dials and the junction of described locking axostylus axostyle.
Adopt after technique scheme, the utility model is compared with existing background technology, tool has the following advantages: whether the utility model is can sense switch cabinet bus charged, cannot unlocking operation earthing when charged, make earthing akinesia, prevent earthing misoperation in the situation that of switch cabinet electrified, prevent electric thing to occur.
Brief description of the drawings
Fig. 1 is that the utility model does not detect the view when charged;
Fig. 2 is that the utility model detects the view when charged;
Fig. 3 is the schematic diagram of the end of locking axostylus axostyle while stretching into earthing handle hole;
Fig. 4 is the circuit control section schematic diagram in the utility model cabinet.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
As shown in Figure 1, switch cubicle has cabinet 2 and covers the panel 1 before cabinet 2, panel 1 is provided with earthing handle hole 11, the utility model earthing anti-misoperation apparatus comprises the holder 12 and the locking axostylus axostyle 3 that are arranged on panel 1 behind, two holders 12 arrange in the left and right sides respectively along the direction shown in arrow in figure, and be parallel to each other and be relatively fixed on the behind of panel 1, on holder 12, respectively have the relative sliding eye in position, the two ends of locking axostylus axostyle 3 are enclosed within on the sliding eye of holder 12 actively, the position of locking axostylus axostyle 3 between two holders 12 is provided with respectively and dials 32 toward two extended pins 31 of direction perpendicular to axial direction and release, release is dialled the 32 strip holes of opening by panel 1 behind from panel 1 vertically outside extending panel 1, position on locking axostylus axostyle 3 between two holders 12 is also arranged with spring 33, spring 33 one end are against on a holder 12, the other end be against release dial 32 with the junction of locking axostylus axostyle 3, elastic force by spring 33 stretches in earthing handle hole 11 end of locking axostylus axostyle 3, see Fig. 3, because the end of locking axostylus axostyle 3 has been stretched in earthing handle hole 11 inside, thereby operating personnel cannot come in inserting hole, earthing to be operated with instrument.
So need first release to operate the earthing in earthing handle hole 11, release is to dial and to stir toward the unlocking direction shown in arrow 32 from panel 1 external application handgrip release, the compressed locking axostylus axostyle 3 that makes of spring 33 moves axially some distances toward unlocking direction, the end of locking axostylus axostyle 3 exits earthing handle hole 11, no longer be blocked in hole, operating personnel just can inject earthing handle hole 11 with instrument, thereby rotation earthing closes a floodgate or the operation of separating brake.
In order to prevent misoperation, prevent operational grounding cutter in charged, the utility model is also provided with the transducer 4, electrification display 5 and the electromagnet 6 that are arranged on cabinet 2 inside, circuit diagram as shown in Figure 3, owing to being mounted in cabinet 2 inside, so do not demonstrate on Fig. 1 and Fig. 2, electromagnet 6 has a push rod 61, sees Fig. 1 and Fig. 2.
Connecting sensor 4 on bus, transducer 4 is electrically connected with electrification display 5, and electrification display 5 is electrically connected with electromagnet 6.Whether transducer 4 is charged for detection of bus, and detection signal can be sent to electrification display 5, in the time that bus is charged, the K switch 1 of electrification display 5, K2 closure make electromagnet 6 charged, push rod 61 on electromagnet 6 stretches out forward cabinet 2, and now, push rod 61 blocks the pin 31 (as shown in Figure 2) on locking axostylus axostyle 3, make operating personnel not stir release toward unlocking direction and dial 32, thereby cannot in the time that bus is charged, carry out on/off switch operation to earthing; In the time that bus is not charged, electromagnet 6 adhesives, push rod 61 retrude (see figure 1) on electromagnet 6, now, push rod 61 can not block the pin 31 on locking axostylus axostyle 3, operating personnel can stir release toward unlocking direction and dial 32, make the end of locking axostylus axostyle 3 exit earthing handle hole 11, thereby can carry out on/off switch operation to earthing.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
