Description
Technical field
The utility model relates to a kind of switching device, relates in particular to a kind of three-station anti-misoperation apparatus.
Background technology
In prior art, high-tension switch cabinet three working-position interlock mechanism generally adopts cabinet door to carry additionally lock side formula, and this this interlock method just need can carry out next step operation after removing manually; When operating personnel's inoperation level is not mature enough or exert oneself excessive, three-station can be caused directly to get to ground connection from connection status or directly get to connection status by ground connection, cause significant trouble.Reliability is low simultaneously, and fail safe is low, and is easy to cause misoperation, reduces the security performance of equipment, brings very large hidden danger to the personal safety of operating personnel and power grid operation.
Therefore, a kind of three-station anti-misoperation apparatus of economical and practical, simple and flexible is needed badly.
Utility model content
The technical problems to be solved in the utility model is to provide the three-station anti-misoperation apparatus providing a kind of economical and practical, simple and flexible.
For achieving the above object, the utility model provides a kind of three-station anti-misoperation apparatus, comprises and selects sheet and inner misoperation-proof mechanism, it is characterized in that: described inner misoperation-proof mechanism is made up of rotating disk projection, spacing shelves and rotary screw; Described rotating disk projection is inserted and is fixed in three-station handle hole, and left and right is respectively provided with one; Described spacing shelves are fixedly connected with integral with described rotary screw; Described rotary screw is provided with three station state and identifies spacing rotating disk; Described selection sheet is connected with rotary screw and spacing shelves; Described rotating disk is protruding, rotary screw is individually fixed on same base.
Preferably, described selection sheet is provided with ground connection, two states of closing a floodgate indicate, and described selection sheet can left and right activity.
Preferably, described spacing rotating disk is provided with closing position, isolated bit, sub-gate position three disconnecting link status signs.
The beneficial effect that the utility model has is: the utility model guarantees that operating personnel are because of the firmly excessive misoperation caused, and ensures that disconnecting link directly can not be got to ground connection or connection status by operating personnel.Guarantee misoperation to occur, improve the security performance of equipment, ensure the stable of operation of power networks, ensured the safety of operating personnel further, greatly reduced the personal safety hidden danger of operating personnel.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 to 7, a kind of three-station anti-misoperation apparatus of the utility model, comprise ground connection, close a floodgate three station manipulations selection sheet 1 and inner misoperation-proof mechanisms 3, inner misoperation-proof mechanism 3 is made up of rotating disk projection 4, spacing shelves 5 and rotary screw 6; Described rotating disk protruding 4 inserts and is fixed in three-station handle hole 2, and left and right is respectively provided with one; Described spacing shelves 5 are fixedly connected into integral molding structure with described rotary screw 6; Described rotary screw 6 is provided with three station state and identifies spacing rotating disk 7, wherein three station state identify on spacing rotating disk 7 and are provided with closing position, isolated bit, sub-gate position three disconnecting link status signs; Described selection sheet 1 is connected with spacing shelves 5 by rotary screw 6; Described sabot projection 4, connection rotary screw 6 are individually fixed on same base.
As shown in Figure 7, when three station state marks are in isolated bit 9, when being namely in isolation, operation selects sheet 1 can left rotation and right rotation, and when selecting sheet 1 to turn clockwise in Fig. 1 to get to co-bit, in Fig. 6, spacing shelves 5 turn clockwise, now combined floodgate can be operated, after combined floodgate, in Fig. 2, spacing shelves 5 block the sabot projection 4 that in Fig. 2,1 three stations connect, and make now three-station to get to isolation and directly can not get to earthing position.When three-station is got to isolation, as needs carry out ground connection operation, then need to select sheet 1 to get to ground connection marker location in Fig. 1, now can carry out ground connection operation.When three-station is in earthing position, make now disconnecting link to be got to isolated bit because shelves spacing in Fig. 6 block the sabot projection 4 that in Fig. 6,1 three stations connect.Thus to avoid in operating process firmly excessive directly disconnecting link is got to ground connection or connection, greatly strengthen the security performance of equipment, guarantee power grid operation, further ensure the safety of operating personnel.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
