Description

The interlock of switchgear electric ground switch
Technical field
The utility model relates to a kind of interlock of switchgear electric ground switch, is used to solve the machinery five anti-interlockings after switchgear grounding switch is realized electric operating, belongs to power transmission and distribution switchgear technical field.
Background technology
In power transmission and transformation system; Switchgear is wherein important part; In electric power system, realizing the conveying and the distribution of electric energy; Along with the maturation of technology such as computer, transducer, information, communication, control theory, network, power electronics, will be towards the development of intelligent switch device orientation, intelligent switch equipment has automatic measurement, status monitoring, automatic diagnosis, adjusting automatically, Based Intelligent Control and basic functions such as control centre communicates by letter.The electric ground switch operation realizes that as the some of intelligent control switch equipment the Based Intelligent Control of switching devices makes switchgear operation simple and convenient, guarantees the convenience of product maintenance.
Because the armored withdraw type ac metal closing switch gear adopts the middle breaker structure, this switchgear operation is simple, and is easy to maintenance, in industry 10KV system, becomes leading products.But because this switchgear grounding switch adopts manual operation, operation is effort relatively, makes the maintenance of product not too convenient, and along with the intelligent switch Equipment of Development, the electric ground switch operation will replace manual manipulation mode.But break down for preventing the electric ground switch operation; Keep manual earthed switch operating function simultaneously; As its important some,, will certain influence be arranged switching devices machinery five anti-interlockings for switchgear machinery five anti-interlockings owing to increase the electric ground switch operating function.When the service position, earthed switch can not close a floodgate like: circuit breaker; Earthed switch is at closing position, and circuit breaker can not shake into to the service position.When adopting the electric ground switch operation, former interlocking device can't realize machinery five anti-interlocks.
Summary of the invention
The purpose of the utility model provides a kind of interlock of switchgear electric ground switch, to solve the machinery five anti-interlockings after switchgear grounding switch is realized electric operating.
In order to achieve the above object, the utility model technical scheme provides a kind of interlock of switchgear electric ground switch, it is characterized in that; Comprise connecting lever, an end of connecting lever is fixed, and the other end is fixedly connected the right guide rail blocking lever of handcart; The right guide rail blocking lever of handcart is fixedly connected the manual operation interlocking gear, and the manual operation interlocking gear is fixedly connected an end of chain bent plate, and the middle part of chain bent plate is provided with limited impression; The middle part of connecting lever is fixedly connected connecting plate one end, and the other end of connecting plate is fixedly connected interlock plate, the middle part of the interlock plate earthed switch operating axis that is movably connected; The earthed switch operating axis is fixedly connected cam; Cam is meshed with roller, and roller is fixedly connected with interlock plate, and an end of earthed switch operating axis is located in the limited impression.
Preferably, described earthed switch operating axis also is fixedly connected left positioning sleeve and right positioning sleeve, and left positioning sleeve and right positioning sleeve lay respectively at the left side of interlock plate and the right side of cam.
Compared with prior art, the utlity model has following advantage:
1, mechanism is simple, rotation is flexible;
2, dual interlock mechanism is separate, mutually noninterfere;
3, good being linked of dual interlock two cover mechanisms, interlocking is reliable.
Description of drawings
Fig. 1 is the interlock front view of switchgear electric ground switch;
Fig. 2 is an A-A cutaway view among Fig. 1.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1; Be the interlock front view of switchgear electric ground switch, the interlock of described switchgear electric ground switch is made up of connecting lever 1, connecting plate 2, interlock plate 3, cam 4, left positioning sleeve 5, roller 6, right positioning sleeve 7, earthed switch operating axis 8, handcart right side guide rail blocking lever 9, interlocking bent plate 10, manual operation interlocking device 11 and limited impression 12.As shown in Figure 2, be A-A cutaway view among Fig. 1, an end of connecting lever 1 is fixed; The other end is fixedly connected the right guide rail blocking lever 9 of handcart, and the right guide rail blocking lever 9 of handcart is fixedly connected manual operation interlocking gear 11, and manual operation interlocking gear 11 is fixedly connected an end of chain bent plate 10; The middle part of chain bent plate 10 is provided with limited impression 12; The middle part of connecting lever 1 is fixedly connected connecting plate 2 one ends, and the other end of connecting plate 2 is fixedly connected interlock plate 3, the middle part of the interlock plate 3 earthed switch operating axis 8 that is movably connected; Earthed switch operating axis 8 is fixedly connected cam 4; Cam 4 is meshed with roller 6, and roller 6 is fixedly connected with interlock plate 3, and an end of earthed switch operating axis 8 is located in the limited impression 12.Described earthed switch operating axis 8 also is fixedly connected left positioning sleeve 5 and right positioning sleeve 7, and left positioning sleeve 5 lays respectively at the left side of interlock plate 3 and the right side of cam 4 with right positioning sleeve 7.
Behind the earthed switch separating brake, when driven by motor earthed switch operating axis 8 rotated, cam 4 was along with rotation; Simultaneously cam 4 promotes rollers 6 and rotates, because roller 6 is fixedly connected with interlock plate 3, so interlock plate 3 moves up along with roller 6 rotations and spurs connecting lever 1; Connecting lever 1 drives the right guide rail blocking lever 9 of handcart and moves up, and the right guide rail blocking lever 9 of handcart drives chain bent plate 10 and moves up, after earthed switch closes a floodgate; When driven by motor earthed switch operating axis 8 rotated, cam 4 was along with rotation, and cam 4 promotes roller 6 rotations simultaneously; Because roller 6 is fixedly connected with interlock plate 3, so interlock plate 3 rotates along with roller 6 and moves down and spur connecting lever 1, and connecting lever 1 drive handcart right side guide rail blocking lever 9 moves down; The right guide rail blocking lever 9 of handcart drives chain bent plate 10 and moves down, and realizes the interlock with circuit breaker cart.
When the operation of manual earthed switch, at first start operation interlocking mechanism 11 to interlocking bent plate 10 downward pressure zones and move down, handcart right side guide rail blocking lever 9 is moved; Driving earthed switch operating axis 8 moves down; Earthed switch closes a floodgate, and interlocking bent plate 10 is positioned outer in depressed position, has only behind the earthed switch separating brake; Interlocking bent plate 10 just can reset, and realizes five anti-interlocks of manual operation and circuit breaker cart with this.Two cover interlocking devices can switch mutually, and manual operation can intersect with electric operating to be carried out, and just uses Operation and Maintenance.
