Description
Technical field
The utility model relates to a kind of locking device that is applied in the electric power system ring main unit.
Background technology
Every circuit of certain type ring main unit comprises a switch and a ground cutter, can operate by manual, electronic and the three kinds of modes in a distant place.Manual manipulation mode is: use the operating sleeve that has interior hexagonal hole to be enclosed within on the operating nut, turnbarrel can drive the operating nut rotation, nut drives the power transmission shaft be fixed together with it, and power transmission shaft drives the internal mechanism action again, thus the equipment of realization deciliter; The electric operating mode is: control the startup of motor by the control cubicle in the ring main unit, by the driven by motor power transmission shaft, power transmission shaft drives the internal mechanism action again, thus the equipment of realization deciliter; The remote operation mode is: from the startup of Long-distance Control motor, realize the branch closing operation of equipment in the centralized control center.
This type ring main unit only can be realized the locking of manual manipulation mode at present, promptly locks power transmission shaft, and power transmission shaft can not rotate when making manual operation, and this lock mode has following deficiency:
During electric operating, need at first unlocking, carry out electric operating again.If there is not unlocking, motor can be passed to power transmission shaft with power after rotating, and this moment, power transmission shaft was locked, can't rotate.So just might damage motor or damage transmission mechanism.During remote operation, the place does not have operating personnel because of ring main unit, can't unlocking, so remote operation also can't be realized.
Summary of the invention
The problem electronic at this type ring main unit and distant place locking exists, the utility model provides a kind of novel ring main unit locking device, can realize the manual block of this type ring main unit preferably, simultaneously to electronic and not influence of remote operation.Technical solution adopted in the utility model is:
This locking device, comprise sleeve, the sleeve limiting plate, operating nut, operating mechanism panel and be fixed on lockset I and lockset II on the operating mechanism panel, the cross sectional shape of sleeve is a runway shape, the interior hexagonal hole center that sleeve is offered overlaps with one section circular arc center of circle wherein, make between the interior hexagonal hole of sleeve and the two sections circular arcs and form sleeve wall than thickness portion and thin part, the cross sectional shape of sleeve limiting plate is the seemingly circle of being made up of semicircle and roundlet angle, the circle centre position of semicircle has polygonal flower hole, the arc edge of the semicircle projection that makes progress forms prominent edge, power transmission shaft passes the polygonal flower hole and the socket of operating nut inner edge of operating mechanism panel and sleeve limiting plate successively, make the sleeve limiting plate, operating nut and power transmission shaft are fixed together, lockset I and lockset II lay respectively at the below and the top of sleeve limiting plate, when the interior hexagonal hole of sleeve is socketed in the operating nut outer rim, the thin barrel that the space that is surrounded between the prominent edge of sleeve limiting plate and the operating nut can only receiving sleeve.
Can offer sipes on the prominent edge of sleeve limiting plate, form the rectangle projection that is positioned at diverse location.
Because the restriction on prominent edge on the sleeve limiting plate circumference, the direction of sleeve and operating nut socket is defined, cooperate existing lockset, operating sleeve can't be socketed on the operating nut in the time of can realizing the lockset locking, or can not rotate enough angles after the socket, and then solved the manually operated lockout issue of ring main unit.During electronic or remote operation,, so can not influence the rotation of driven by motor power transmission shaft because this lock mode not have directly to lock the operation screw of power transmission shaft or locking and power transmission shaft fixed connection.Promptly this lock mode does not influence the electronic and remote operation of ring main unit.During operating equipment, the sleeve limiting plate is followed power transmission shaft and is rotated together, and top little fillet can the indicating equipment position.
Therefore the utility model structure has simple and practical, easy operating, characteristics that latch effect is good.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that not release is the schematic diagram of turnbarrel;
Fig. 3 is a schematic diagram of separating the unlocking tool turnbarrel;
Fig. 4 is the schematic diagram of this device operation after finishing.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As depicted in figs. 1 and 2, the cross sectional shape of sleeve 11 is a runway shape, the interior hexagonal hole center of its inside overlaps with one section circular arc center of circle wherein, makes the interior hexagonal hole of sleeve 11 form thin barrel therewith between the section circular arc, and forms thickness bucket wall between interior hexagonal hole and the other one section circular arc.The cross sectional shape of sleeve limiting plate 2 be by semicircle and roundlet angle form like circular, the circle centre position of semicircle has polygonal flower hole 4, the arc edge of the semicircle projection that makes progress forms prominent edge.
Power transmission shaft 6 passes circular hole and the polygonal flower hole 4 of sleeve limiting plate 2 and the inner edge socket of operating nut 3 of operating mechanism panel 10 successively, and sleeve limiting plate 2, operating nut 3 and power transmission shaft 6 are fixed together, and sleeve limiting plate 2 is near operating mechanism panel 10.Lockset I5 and lockset II8 are fixed on the operating mechanism panel 10, and they lay respectively at the below and the top of sleeve limiting plate 2.
As shown in Figure 2, during manual operation, the little fillet of sleeve limiting plate 2 is adjusted at horizontal level, sleeve 11 is socketed on the operating nut 3, because the space that three rectangle projections 1 on the sleeve limiting plate semi-circumference and operating nut 3 are surrounded can only hold the thin part of sleeve wall, so sleeve wall is than the necessary alignment sleeve limiting plate 2 no projection one sides of thickness portion, if this moment turnbarrel 11, after very little angle, sleeve wall can be met the lock pin II9 of lockset II8 or the lock pin I7 of lockset I5 than thickness portion, and lock pin can not move when locking.Therefore the rotation of sleeve 11 is prevented from, can not operating equipment, and promptly manual operation is locked.
As shown in Figure 3, untie a lockset, lock pin is mentioned, turnbarrel 11 drives power transmission shaft 6 and sleeve limiting plate 2, makes the action of internal mechanism drive equipment, and manual operation is finished.
As shown in Figure 4, after manual operation is finished, take off sleeve 11, put down lock pin and locking lockset.At this moment, sleeve 11 is because there be stopping of lock pin can not be socketed on the operating nut 3, and manual operation is locked again.After the operation, sleeve limiting plate 2 turns over certain angle, and new position is pointed at the roundlet angle.
In operating process, lockset does not act directly on the transmission mechanism, and is therefore electronic or remote operation is unrestricted.
