Specific implementation mode
Embodiment one:
As shown in Figures 1 to 3, the present invention provides a kind of anti-misoperation apparatus for ring main unit, and ring main unit includes 1 He of cabinet
Cabinet door 2 on cabinet 1, anti-misoperation apparatus include the high pressure sensor 7 being set on high-tension circuit and high pressure sensor 7
The control circuit 8 of electrical connection, the driving device being electrically connected with control circuit 8 and the mechanical lock on 2 back side of cabinet door, driving dress
It sets including motor 9 and the set square being electrically connected with motor 93, set square 3 is set to the back side of cabinet door 2 and can move left and right, mechanical lock
The hook-shaped positive stop strip 5 for including the spacing ring 4 on 1 inner wall of cabinet and coordinating with spacing ring 4, set square 3 and hook-shaped positive stop strip 5
Cooperation and the rotation of hook-shaped positive stop strip 5 can be driven to realize hook-shaped positive stop strip 5 and the cooperation of spacing ring 4 and detach, the survey of high pressure sensor 7
When obtaining high-tension circuit electrification, the cabinet door 2 to prevent operating personnel from accidentally opening ring main unit operates, and control circuit 8 controls motor 9
Work, motor 9 control set square 3 and are moved to close to the direction of spacing ring 4, and set square 3 drives hook-shaped positive stop strip 5 to rotate down,
Hook-shaped positive stop strip 5 turns to the position coordinated with spacing ring 4 so that cabinet door 2 is remained turned-off in inside, and operating personnel are in ring main unit
Outside can not open cabinet door, ensure that, in electrification, the cabinet door of ring main unit can not be opened, and operating personnel can not operate looped network
Cabinet keeps the use of ring main unit safer.
In the present embodiment, hook-shaped positive stop strip 5 includes linkage section 52 and the limit section 53 with the cooperation of spacing ring 4,2 back side of cabinet door
Equipped with fixed plate 6, linkage section 52 is rotatablely connected with fixed plate 6.It is rotatablely connected, is realized hook-shaped with fixed plate by the way that linkage section is arranged
Between positive stop strip and spacing ring cooperation with separate between conversion.
Fixed plate 6 is equipped with limiting slot 61, and set square 3 is located in limiting slot 61 and is slidably connected with limiting slot 61 so that
Set square can be slided along limiting slot, keep the rotation of hook-shaped positive stop strip relatively reliable.Meanwhile limiting slot plays limit to set square
The effect of position, as shown in Fig. 2, when set square is in close to the extreme position of spacing ring, the end of hook-shaped positive stop strip and spacing ring
Cooperation, as shown in figure 3, when set square is in the extreme position far from spacing ring, the end of hook-shaped positive stop strip and the position of spacing ring
It sets and separates so that hook-shaped positive stop strip can only rotate in fixed angle, and ensureing hook-shaped positive stop strip, only cause cannot for inordinate rotation
It is normal to reply so that the opening of mechanical lock and closing are relatively reliable.

The present embodiment and the main distinction of embodiment one are that cabinet is equipped with through-hole, and through-hole is located at the lower section of spacing ring,
The end of hook-shaped positive stop strip is equipped with the warning light being electrically connected with control circuit, when hook-shaped positive stop strip coordinates with spacing ring, warning light
Positioned at through hole.
As shown in Figure 4 and Figure 5, cabinet 1 is equipped with through-hole 11, and through-hole 11 is located at the lower section of spacing ring 4, hook-shaped positive stop strip 5
End be equipped with warning light 51, that is, limit, 53 one end far from linkage section 52 be equipped with warning light 51, hook-shaped positive stop strip 5 with limit
When ring 4 coordinates, warning light 51 is located at through-hole 11.The advantages of this arrangement are as follows by the way that through-hole is arranged, operating personnel are in looped network
The outside of cabinet can observe the case where warning light, if from through hole can see the bright i.e. hook-shaped positive stop strip of warning light be in
The position of spacing ring cooperation, then judge that mechanical lock is closed, if cannot see that the bright i.e. hook-shaped limit of warning light from through hole
Position item is in the position separated with spacing ring, then judges that mechanical lock is in the open state, is conveniently operated personnel and understands mechanical lock
State.Facilitate staff to carry out test judgement to anti-misoperation apparatus, ensures that anti-misoperation apparatus is constantly in normal work
State.
Transparent glass is equipped in through-hole 11, transparent glass blocks through-hole 11 so that external dust, toy etc. cannot lead to
Cross the inside that through-hole enters cabinet so that the use of ring main unit is more safe and reliable;Simultaneously because glass is transparent glass, it will not
Influence the state that staff observes warning light.
It should be understood that transparent glass may be transparent plastic sheet.
In addition to above preferred embodiment, the present invention also has other embodiments, those skilled in the art can be according to this
Invention makes various changes and modifications, and without departing from the spirit of the present invention, should all belong to appended claims of the present invention and determine
