Description

A kind of manually handle three position mechanism used for high-voltage switch
Technical field
The present invention relates to power industry field of switch equipment more particularly to a kind of three stations of manually handle used for high-voltage switch Mechanism.
Background technology
CJ8-5 types operating mechanism is for GIS-40.5 switchgears, ZHW mouths -126, ZF mouths -126, ZF mouths -252 and required turn Comparable disconnecting switch, earthing switch and on-load switch are closed and are cut-off and be used square therewith.
It is embedded in use, positioning bulb and entering in the axis pin of worm gear so that worm gear cannot rotate, and reach realizing middle limiting Effect, when electromagnet obtains it is electric after, the shift fork that electromagnetic actuation to be stuck in positioning bulb is attracted with the actuation of electromagnet, but It is that the drawback present in this structure is unstable for shift fork movement, downward shift and left and right deviate the card for being easy to cause electromagnet It is stagnant so that the internal heat generation of electromagnet short time and cause mechanism performance unstable, secondly, and in the case that shift fork is unstable, two Shift fork is easy to block and make electromagnet that can not be attracted, and mechanism is caused to cannot achieve the function of separating brake limit.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of manually handle three position mechanisms used for high-voltage switch, pass through hand Flowing mode is operated, and the reliability of switch motion greatly improved.
The present invention is achieved through the following technical solutions, provides a kind of manually handle three position mechanism used for high-voltage switch, Including intermeshing turbine and worm screw, and the left operating lever positioned at the turbine both sides and right operating lever, the left operation It has been connected through a screw thread swivel nut respectively in bar and right operating lever;
Further include the left connecting plate being threaded through respectively on hinged shaft and right connecting plate, the left connecting plate one end difference mutually separate with right connecting plate It is set in left operating lever, in front of the swivel nut in right operating lever, and the overlap aperture internal diameter on left connecting plate and right connecting plate is more than and is arranged place The outer diameter of left operating lever and right operating lever is equipped between left connecting plate and the mutually close one end of right connecting plate and is mounted on the turbine Detent mechanism, between two hinged shafts and turbine respectively fixed restricted left connecting plate rotate counterclockwise, the gear that right connecting plate rotates clockwise Bar is equipped with the torsional spring of fixed setting on two hinged shafts.
This programme when in use connects the switching mechanism of the wheel shaft of turbine and electrical equipment, fixed when being in middle position state Position mechanism is between left connecting plate and right connecting plate, and left connecting plate and right connecting plate are adjacent to lever under the action of torsional spring, and to positioning Mechanism forms blocking, to limit turbine rotation;When worm screw is driven by driving device to rotate, turbine rotates clockwise, simultaneously The swivel nut in left operating lever is rotated, swivel nut moves forward under the action of screw thread, to touch left connecting plate, makes left connecting plate around the axis of hinged shaft Line rotates, and left connecting plate loses the blocking to detent mechanism, and turbine smoothly goes to left position;When rotating backward swivel nut, swivel nut is far from left Connecting plate releases the force to left connecting plate, and when driving device rotates backward, turbine rotates counterclockwise, and detent mechanism passes through left connecting plate When end, the elastic force of torsional spring is overcome to depress left connecting plate, to be back to middle position, left connecting plate resets under the effect of torsion spring;Similarly may be used Realize that turbine goes to right position.
As an optimization, the both ends of the worm screw are installed with driven bevel pinion respectively, in the left operating lever and right operating lever One end far from swivel nut is installed with the driving bevel gear engaged with the driven bevel pinion at worm screw both ends respectively.By this prioritization scheme Setting, in rotary threaded sleeve, while rotating backward left operating lever or right operating lever, when left operating lever or right operating lever rotate, It is driven by bevel gear and drives worm screw rotation, to drive turbine rotation so that the rotation of left connecting plate or right connecting plate turns with turbine Dynamic synchronous progress, further improves the efficiency of switch motion, meets high-voltage switch gear and acts rapidity to switch closing and switch opening It is required that.
As an optimization, the left connecting plate includes the "the" shape dropout plate that one end is set in the left operating lever, and With the detachable affixed sincere son of the dropout plate, the sincere son is affixed with hinged shaft.By the way that the dropout plate of "the" shape is arranged, increase The swing angle of left connecting plate, shortens the feeding distance of swivel nut, further improves the flexibility of action, dropout plate and sincere son It is detachably connected, facilitates installation and replacement.
As an optimization, the right connecting plate includes the "the" shape dropout plate that one end is set in the right operating lever, and With the detachable affixed sincere son of the dropout plate, the sincere son is affixed with hinged shaft.By the way that the dropout plate of "the" shape is arranged, increase The swing angle of right connecting plate, shortens the feeding distance of swivel nut, further improves the flexibility of action, dropout plate and sincere son It is detachably connected, facilitates installation and replacement
As an optimization, the slot hole for making it be relatively moved with left operating lever, right operating lever is offered respectively on two dropout plates.This The setting of prioritization scheme slot hole, when swivel nut pushes the movement of dropout plate, position of the dropout plate relative to left operating lever or right operating lever Bigger is moved, the angle bigger for making left connecting plate or right connecting plate rotate further ensures left connecting plate and right connecting plate to detent mechanism solution Except the reliability of limitation.
As an optimization, further include the manual rocking handle equipped with card slot, the card being adapted to the card slot is installed on the swivel nut Pin.Swivel nut rotation is shaken by manual rocking handle, it is more laborsaving and quick, and be stuck on bayonet lock by card slot and realize manual rocking handle With the connection of swivel nut, the set-up time is saved, and conveniently removed after use.
The positioning member of this prioritization scheme is simple in structure, low manufacture cost, and is contacted with sincere son using the cambered surface of roll sleeve, Frictional force is reduced, the fluency of turbine rotation is improved.
Beneficial effects of the present invention are:Control is realized to the rotation of turbine by left connecting plate and right connecting plate, and is manually operated Make swivel nut that axial displacement occur, to realize the station of left, center, right three, correspondingly realizes the combined floodgate of electrical switching mechanism, divides Lock and landing operation, the reliability of mechanism and the flexibility of action greatly improve.
