Description
Technical field
The present invention relates to a kind of movable door mechanism for high voltage switch cabinet.
Background technology
More and more higher to the requirement in the technical performance of withdrawing high-voltage switch equipment, operation use, repair and maintenance etc. in electric power system at present, the particularly requirement of secure context.As the screen body of high voltage switchgear electrified body, both opening of valve seemed particularly important with the accuracy of opening and closing and reliability.
In high voltage switchgear, for contact when avoiding overhauling is charged and jeopardize the personal safety of maintainer, in switch cubicle, generally arrange valve mechanism, when handcart push-on switch cabinet works, valve is opened; When pulling out handcart maintenance, valve is closed, mask tape electrical contact, thus the personal safety of protection maintainer.
Upper and lower valve in the handcart room of current switchgear is generally vertical mechanism, and namely valve moves along guide post is upper and lower, thus opens or shield upper and lower contact.Because main parts size main body in cabinet is in being arranged vertically, for avoid valve and other parts particularly bus mutually interfere and cause fault, generally can only take to increase cabinet space, transmission mechanism for valve is bite often, left and right action is inconsistent, causes valve to tilt, and therefore causes inspection switch cabinet dangerous, cabinet body structure is loose, operates unreliable series of problems of Denging.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of movable door mechanism for high voltage switch cabinet, cost is low, and structure is simple, easy to use, safe and reliable, flexible operation.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
Movable door mechanism for high voltage switch cabinet, comprises valve, it is characterized in that: described valve is up and down rolling screen door of splitting, and comprises roller shutter door-plate and lower roller shutter door-plate; The guide rail of described rolling screen door both sides installing for guaranteeing both sides synchronous movement and accuracy; Described guide rail is micro-to shaped form convex outdoors.
Also comprise the transmission mechanism for drive roller shutter door switch; Described transmission mechanism comprises stone dead wire, fixed pulley and slide block; One end of described stone dead wire is connected with the end winding support in rolling screen door centre position, then arranges along guide rail and draws from the end of guide rail respectively, walk around multiple fixed pulley other end and be fixedly connected with slide block.
Described slide block is nested with on the guide bar; Described guide post is provided with for making the spring that transmission is mild and set back; One end of described spring and the end winding support of guide post, the other end withstands on slide block.
The upper and lower end parts of described valve is respectively equipped with the spool for rolling roller shutter door-plate, and one end of described rolling screen door is fixedly connected with spool, and the other end is arranged along guide rail and extended to valve centre position.
Beneficial effect: movable door mechanism for high voltage switch cabinet provided by the invention, by being set to up and down rolling screen door of splitting, guide rail is set in micro-to shaped form convex outdoors, and the parts that efficiently avoid existing valve and high-tension switch cabinet inside particularly bus interfere the situation causing fault mutually; Both sides are by the mobile synchronous shift of slide block, and lower roller shutter door-plate opens or closes until covered in by upper and lower contact completely simultaneously; Power needed for unlatching is minimum, and stroke is very little, resets reliable; The interlock of rolling screen door and circuit breaker adopts fixed pulley and stone dead wire, can arrange arbitrarily the interlock of valve and handcart, eliminates shift fork arm driving mechanism, greatly simplify the mechanism of breaker of switch cabinet room; Carry out drive transmission device by the baffle plate of circuit breaker or handcart, ensure that in switchgear, upper and lower rolling slat opens or closes until covered in by upper and lower contact completely by transmission stone dead wire simultaneously; Realize the completely isolated of electrified body; Increase the fail safe of maintenance; Safe and reliable, flexible operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention when test position;
Fig. 2 is the structural representation of the present invention when service position.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be a kind of movable door mechanism for high voltage switch cabinet as depicted in figs. 1 and 2, comprise valve, valve is up and down rolling screen door of splitting, and comprises roller shutter door-plate 4 and lower roller shutter door-plate 7; The guide rail of rolling screen door both sides installing for guaranteeing both sides synchronous movement and accuracy; Described guide rail is micro-to shaped form convex outdoors; Also comprise the transmission mechanism for drive roller shutter door switch; Described transmission mechanism comprise stone dead wire 5,8, fixed pulley 3 and slide block 11; One end of stone dead wire 5,8 is connected with the end winding support in rolling screen door centre position, then arranges along guide rail and draws from the end of guide rail respectively, walk around multiple fixed pulley 3 other end and be fixedly connected with slide block 11; Slide block 11 is nested with on guide post 9; Guide post 9 is provided with for making the spring 10 that transmission is mild and set back; One end of spring 10 and the end winding support of guide post 9, the other end withstands on slide block 11; The upper and lower end parts of valve is respectively equipped with the spool 2 for rolling roller shutter door-plate, and one end of rolling screen door is fixedly connected with spool 2, and the other end is arranged along guide rail and extended to valve centre position.
Operation principle:
As shown in Figure 1; When circuit breaker or handcart enter service position from experimental site, along with pushing of circuit breaker, circuit breaker baffle plate 12 contacts with slide block 11, simultaneously extrusion spring 10, and spring 10 compresses in the scope of guide post 9.Fixed pulley 3 is fixing, and upper roller shutter door-plate 4 is by pull-up stone dead wire 5 pulling thus moving upward upwards, and lower roller shutter door-plate 7 is by downward the pulling thus move downward of drop-down stone dead wire 8.Pull-up stone dead wire 5 coordinates three fixed pulleys 3 to do transmission, and drop-down stone dead wire 8 coordinates two fixed pulleys 3 to do transmission, and the while of upper roller shutter door-plate 4 and lower roller shutter door-plate 7, both direction is opened up and down.Now spool 2 rotates, and roller shutter door-plate is coated on the surface of spool 2 along with the rotation of spool 2.Rolling screen door has been opened, and circuit breaker finally enters service position as shown in Figure 2.
As shown in Figure 2; When circuit breaker or handcart enter experimental site from service position, along with the pull-out of circuit breaker, spring 10 starts expansion equally in the scope of guide post 9, slide block 11 is outwards pushed up simultaneously; Pull-up stone dead wire 5 and drop-down stone dead wire 8 setting in motion under the rotation of fixed pulley 3, spool 2 rotates simultaneously; In drive, roller shutter door-plate 4 moves downward, and lower roller shutter door-plate 7 moves upward.Until upper roller shutter door-plate 4 contacts with each other with lower roller shutter door-plate 7, circuit breaker baffle plate 12 and slide block 11 are thrown off.Rolling screen door has closed, and circuit breaker finally enters experimental site as shown in Figure 1; Can pin with padlock under closed state between upper roller shutter door-plate 4 and lower roller shutter door-plate 7, avoid the personal safety of maintainer.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
