The interlock mechanism comprises a front lower door plate, a ground switch operating shaft, a guide rail interlock mechanism, a baffle, a fixing plate and a crank-slider mechanism, wherein the crank-slider mechanism is fixed at the front end of the ground switch operating shaft, the guide rail interlock mechanism is mounted on the right side of a guide rail of a switch cabinet, a crank arm is riveted on the ground switch operating shaft, a bent plate is fixed on the crank arm and the baffle, a small shaft is welded at one end of the baffle and rotates around the fixing plate, and the other end of the baffle is connected with the guide rail interlock mechanism via a pulling plate. The interlock mechanism can realize interlock among the ground switch, the handcart of the circuit breaker and a front door plate, has the advantages of simple mechanism operation, low cost, convenient utilization and the like, and provides a novel solution of operation, protection and control of switch gears.
Description
Technical field
The utility model relates to a kind of medium voltage switchgear equipment operation necessary " five anti-interlockings " structural element, specifically a kind of mesolow switchgear assembly earthed switch and circuit breaker cart and front door interlocking device.
Background technology
Earthed switch and circuit breaker cart are the main elements of switchgear, occupy considerable status in the overall formation of switchgear.
At present, in medium voltage switchgear equipment, for the interlocking of earthed switch and circuit breaker cart, the interlocking of Xiamen behind the switch cubicle is to increase the safety to device operator and maintenance personal, the switchgear of different manufacturers, different model, the mode difference of its realization; For the indication interlocking of earthed switch deciliter state on the front door of switch cabinet plate, most of producers all do not do, and just make a less sign near earthed switch operation macro-axis, and the user is ignored.
The utility model content
The utility model provides and has been pressed into cover switchgear grounding switch and handcart and front door interlocking device in a kind of, interlocks and has problem loaded down with trivial details, that reliability is not high to solve existing earthed switch and circuit breaker cart.
Door-plate, earthed switch operating axis under before the utility model the utility model comprises, also comprise guide rail interlocking device, baffle plate, fixed head, slider-crank mechanism, slider-crank mechanism is fixed on the front end of earthed switch operating axis, guide rail interlocking device is contained in the right side of the guide rail of switch cubicle, connecting lever is equipped with in riveting on described earthed switch operating axis, be fixed with bent plate on connecting lever and the baffle plate, one end of baffle plate is welded with little axle, little axle rotates around fixed head, and the other end of baffle plate links to each other with guide rail interlocking device by arm-tie.
The utility model can be grounded switch and circuit breaker cart and front door interlocking device.It is simple to operate to have mechanism; Characteristics such as cost is low, and is easy to use.For operation, protection and the control of switchgear provides new solution.
Below in conjunction with accompanying drawing the utility model is described further.

Embodiment
Fig. 2 shows earthed switch and the local figure of front door interlocking device, and Fig. 3 shows the local figure of earthed switch and circuit breaker cart and front door interlocking device.
Door-plate 1, earthed switch operating axis 2 under before the utility model comprises, also comprise guide rail interlocking device 9, baffle plate 4, fixed head 8, slider-crank mechanism, slider-crank mechanism is fixed on the front end of earthed switch operating axis 2, guide rail interlocking device 9 is contained in the right side of the guide rail 10 of switch cubicle, connecting lever 7 is equipped with in riveting on earthed switch operating axis 2, be fixed with bent plate 5 on connecting lever 7 and the baffle plate 4, one end of baffle plate 4 is welded with little axle 14, little axle 14 rotates around fixed head 8, and the other end of baffle plate 4 links to each other with guide rail interlocking device 9 by arm-tie 6.
Guide rail interlocking device 9 (Fig. 4, Fig. 5) comprises interlock plate 11, shifting shaft 15, spring 16, and interlock plate 11 is located on the shifting shaft 15, and shifting shaft 15 is provided with spring 16, and shifting shaft 15 is welded on the baffle plate 4.
Slider-crank mechanism is made up of connecting plate 3 and sliding panel 12, and connecting plate 3 links to each other with sliding panel 12.Post sign 13 on the sliding panel 12.
When interlock plate 11 is blocked, arm-tie 6 can not be drop-down, and arm-tie 6 is when drop-down, and little axle 15 is rotated, and resets the state that keeps earthed switch handle hole 18 to be blocked by spring 16.
When earthed switch is in "on" position, connecting lever 7 stops on the bent plate 5 and moves that like this, baffle plate 4 can not shelter from earthed switch operating axis 2, after the prompting user must decompose low switch earlier, just can advance car, on the other hand, when circuit breaker cart during in the service position, the handcart right flank will stop that interlock plate 11 sticks up in cabinet, baffle plate 4 can not press downwards by shifting shaft 15, and earthed switch operating axis 2 is blocked, and earthed switch can not be operated.
Switchgear is under inspecting state, and promptly under the earthed switch "on" position, circuit breaker cart does not allow to be advanced to the service position by the test position; Earthed switch is under gate-dividing state, and circuit breaker cart just allows to be advanced to the service position by the test position; Have only when handcart is in open position/test position or shift out outside the cabinet, interlock plate 11 is hided in the outside of guide rail 10, and baffle plate 4 could be stirred up and down simultaneously, exposes earthed switch operating axis 2, and it is unimpeded to enter the track road, and at this moment earthed switch could closing operation.
After earthed switch closes a floodgate, interlock will drive interlock plate 11 and stick up in cabinet, and horizontal being inserted in stops on the guide rail 10 that handcart moves, and handcart can not be advanced to the service position; Slider-crank mechanism makes rotatablely moving of earthed switch operating axis 2 become rectilinear motion, before the switchgear down on the door-plate 1 by earthed switch state display aperture 17 to show branch on the rectilinear motion sliding panel 12, to close sign 13 clear and definite indication is arranged, inform the state of user's earthed switch.
Earthed switch is under gate-dividing state, and circuit breaker cart just allows to be advanced to the service position by the test position.
Have only when handcart is in open position/test position or shift out outside the cabinet, earthed switch could closing operation.
