Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of case as shown in Figure 1 becomes the protector of high-tension switch cabinet, comprise switch shaft 6, connecting lever 1 and locking support 8, described connecting lever 1 one end and switch shaft 6 one end are fixed by socket, the swivel head 4 of connecting lever 1 other end runs through the first through hole 11 on cabinet gate 9, and the first described through hole 11 as shown in Figure 6; Described locking support 8 is fixedly connected on the inner side at cabinet gate 9, and passes through clamping mechanism deciliter between described locking support 8 and connecting lever 1.As shown in Figure 1, Figure 2, Figure 4 shows, clamping mechanism is wherein by positioning clamping pin 5 and draw-in groove 12 mix proportions, and described positioning clamping pin 5 is fixedly connected on connecting lever 1 and near swivel head 4, described draw-in groove 12 is positioned on locking support 8, in the time that connecting lever 1 rotates, positioning clamping pin 5 separates or engaging with draw-in groove 12.
As shown in Figure 2 and Figure 3, on described connecting lever 1, one end relative with swivel head 4 offers counterbore 2, and this counterbore 2 is a blind hole, and connecting lever 1 is fixed by socket by this counterbore 2 and one end of switch shaft 6, and wherein, described swivel head 4 is square swivel head.This sleeve structure both can make the axial space of the assembly that connecting lever 1 and switch shaft 6 form reduce, and then the overall dimension of case change high-tension switch cabinet is also correspondingly reduced, can prevent that again connecting lever 1 connecting lever 1 in the time being socketed with switch shaft 6 was inserted in dark and caused switch shaft 6 to damage the isolating switch in case change high-tension switch cabinet; And the square swivel head 4 on connecting lever 1 is gone back handled easily personnel and directly connecting lever 1 is rotated to operation from the outside of case change high-tension switch cabinet.As shown in Figure 4, Figure 5, described locking support 8 is L-shaped, and its one end offers two the second through holes 13, and the other end offers a draw-in groove 12, and draw-in groove 12 is wherein " U " shape.When mounted, utilize two screws or bolt locking support 8 can be fixed on to the inner side at cabinet gate 9 by the second through hole 13, and can effectively prevent that locking support 8 from rotating with respect to cabinet gate 9." U " shape draw-in groove 12 wherein can also increase the contact area between positioning clamping pin 5 and the locking support 8 on connecting lever 1, thereby has improved the mechanical latching reliability of case change high-tension switch cabinet.
In order to facilitate suit, the dismounting of connecting lever 1 and switch shaft 6, spring catch 7 can be set on switch shaft 6, the positioning through hole 3 cooperatively interacting with spring catch 7 is set simultaneously on connecting lever 1.In the time that connecting lever 1 need to be fixed with switch shaft 6 suits, because spring catch 7 has certain elastic telescopic amount, the counterbore 2 inboard compression spring catch 7 of connecting lever 1 one end until the positioning through hole 3 on connecting lever 1 align with spring catch 7, now spring catch 7 elasticity reach in positioning through hole 3, make connecting lever 1 relative fixing in a circumferential direction with switch shaft 6; In the time that connecting lever 1 separates with switch shaft 6,, can remove the alignment restrictions of spring catch 7, thereby make connecting lever 1 depart from switch shaft 6 until the top of spring catch 7 is sunk to below counterbore 2 inner sides of connecting lever 1 one end by Compress Spring pin 7.The direct driving switch axle 6 of rotation of considering connecting lever 1 moves, in order to strengthen the torsional rigidity of connecting lever 1 and switch shaft 6, extend its useful life, two spring catch 7 can be further set on switch shaft 6, correspondingly, two positioning through hole 3 that cooperatively interact with spring catch 7 are also set on connecting lever 1, as shown in Figure 1 and Figure 2.
Adopt the utility model of said structure to cancel the mechanical lock that traditional volume is larger, the isolating switch front end that becomes high-tension switch cabinet at case installs special connecting lever 1 and positioning clamping pin 5 additional, and with the inner side at the interconnective cabinet of cabinet body frame 10 gate 9, locking support 8 is being installed, and between locking support 8 and connecting lever 1, pass through suit clamping, after cabinet gate 9 is closed, if need to divide, while closing the operation of isolating switch, can make positioning clamping pin 5 and the draw-in groove 12 on locking support 8 carry out mechanical chain by the swivel head 4 on rotation connecting lever 1, prevent mistakenly entering charged chamber, be isolating switch close a floodgate charged after, cabinet gate 9 can not be opened.Carry out electrical interlock by isolating switch auxiliary contact and breaker coil simultaneously, prevent that on-load from dividing, closing isolating switch and preventing from dividing by mistake, closing by mistake circuit breaker.Therefore, enforcement of the present utility model can reduce the cabinet size of case change high-tension switch cabinet effectively, to meet the designing requirement of cabinet miniaturization; Meanwhile, easy for installation, and safe and reliable, equipment operating, security of operation can be ensured, and standardized structural design can be realized, be conducive to reduce case and become holistic cost.
The foregoing is only preferred embodiment of the present utility model and oneself; not in order to limit the utility model; it should be pointed out that all any amendments of doing within spirit of the present utility model and principle, be equal to replacement and improvement etc., within all should being included in protection range of the present utility model.
