Description
Technical field
The utility model belongs to power domain, especially a kind of SF
6ring main unit anti-gas-leak closed bite brake separating mechanism.
Background technology
SF
6during ring main unit gas leakage, the panel of cabinet there is air pressure to indicate, can only find that descendant is inoperation.In this, structure also exists very large potential safety hazard.Continue operation as do not noticed air pressure instruction in operating personnel's negligence, the consequence caused is hardly imaginable.Along with the continuous lengthening of operation hours, very large potential safety hazard certainly will be there is.
Through retrieval, find one section of patent documentation relevant to this patent content, publication number is the Chinese patent of CN103811202A, which disclose a kind of cam on/off switch mechanism of device for switching, comprise for the cam handle (2) by device for switching combined floodgate or separating brake, push rod (3), thruster (4) and base shell (1), cam handle (2) comprises handle (S4), cam (S5) and rotating shaft (S0), cam (S5) is set in rotating shaft (S0), handle (S4) is fixed in cam (S5) top, one end of push rod (3) is connected with the output of thruster (4), the other end and the cam (S5) of push rod (3) are connected, handle (S4) is connected with device for switching handle or device for switching arm pivot post, thruster (4) drives push rod (3) to do reciprocating linear motion, push rod (3) drives cam handle (2), device for switching handle is done clockwise or is rotated counterclockwise.
By contrast, there is baroque problem in above-mentioned patent publication us.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of SF
6ring main unit anti-gas-leak closed bite brake separating mechanism, this mechanism is simple, be easy to realize, eliminate potential safety hazard.
Scheme of the present utility model is achieved in that
A kind of SF
6ring main unit anti-gas-leak closed bite brake separating mechanism, comprise fan-shaped display panel, pointer, connecting rod and coupled magnets, described connecting rod is coaxially inlaid in sleeve pipe, support in this sleeve pipe and cabinet is solidly installed, the leading section of described connecting rod is fixedly mounted with fan-shaped display panel, the front end face of this fan-shaped display panel is provided with the pointer be packed in cabinet, the rearward end of this connecting rod is fixedly mounted with coupled magnets, the connecting rod surface thereof of described fan-shaped display panel rear end face is fixedly mounted with the locking bar of L-type structure, the cantilever end end of this locking bar is positioned at the upper left side of the driving hole of on/off switch spanner on cabinet front panel, when connecting rod drives locking bar to be rotated counterclockwise, the cantilever end of locking bar is just in time positioned at above the driving hole of on/off switch spanner.
And the angle of inclination of described locking bar is 0-20 degree.
Advantage of the present utility model and good effect are:
Mechanism achieves the object of gas leakage closed bite separating brake by locking bar, its structure is simple, be skillfully constructed, be easy to realize and cost low, there is the potential safety hazard of misoperation after eliminating warning value, and can be applicable to the interlock of ring main unit of the same type.The utility model has dependable performance, feature simple to operation, has the value of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the structural representation of gas leakage blocking of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of SF
6ring main unit anti-gas-leak closed bite brake separating mechanism, as shown in Figure 1 and Figure 2, comprise fan-shaped display panel 4, pointer 5, connecting rod 3 and coupled magnets 1, described connecting rod is coaxially inlaid in sleeve pipe 2, support 9 in this sleeve pipe and cabinet is solidly installed, the leading section of described connecting rod is fixedly mounted with fan-shaped display panel, and the front end face of this fan-shaped display panel is provided with the pointer be packed on cabinet, and the rearward end of this connecting rod is fixedly mounted with coupled magnets.
Innovative point of the present utility model is:
The connecting rod surface thereof of described fan-shaped display panel rear end face is fixedly mounted with the locking bar 6 of L-type structure, and the cantilever end end 6A of this locking bar is positioned at the upper left side of the driving hole 8 of on/off switch spanner 7 on cabinet front panel; When there is gas leakage, connecting rod drives locking bar to be rotated counterclockwise, in Fig. 2, the direction of arrow is direction of rotation, the cantilever end of locking bar is just in time positioned at above the driving hole of on/off switch spanner, after now inserting spanner in driving hole, owing to being subject to the restriction of locking bar, divide-shut brake spanner can not move up, and then divide-shut brake handle socket (not shown) can not be opened, namely can not carry out breaking-closing operating, achieve the object of ring main unit gas leakage locking.
The angle of inclination A of described locking bar is 0-20 degree.
Air pressure instruction principle in the utility model belongs to prior art, thus introduces no longer in detail in present patent application.
Mechanism achieves the object of gas leakage closed bite separating brake by locking bar, its structure is simple, be skillfully constructed, be easy to realize and cost low, there is the potential safety hazard of misoperation after eliminating warning value, and can be applicable to the interlock of ring main unit of the same type.The utility model has dependable performance, feature simple to operation, has the value of wide popularization and application.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other execution modes drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
