Abstract
The invention discloses a three-in-two program lock interlocking apparatus of a ring main unit. The apparatus comprises three mounting plates arranged on three switch cabinets respectively, lock bodies mounted on the mounting plates and isolation switch main shafts arranged on the mounting plates in a sleeving manner, wherein connecting shafts are movably arranged in the lock bodies; one end of each connecting shaft extends out of each lock body and is fixedly connected with a limiting block; each isolation switch main shaft is fixedly sleeved with an upper limiting sleeve; the three lock bodies are configured with two common keys; and when the limiting blocks are matched with the upper limiting sleeves, the isolation switch main shafts are locked and do not rotate relative to the mounting plates, and the switch cabinets are in closed states. The interlocking apparatus is simple in structure; only two switch cabinets are in the closed states; the three lock bodies are only configured with the two common keys, and when the switch cabinets are in the closed states, the keys inserted into the lock bodies cannot be pulled out, so that the misoperation is effectively prevented; and the interlocking apparatus is safe and reliable.
Description
Technical field
The present invention relates to ring main unit technical field, particularly relate to a kind of ring main unit three close two procedure lock interlocks.
Background technology
Ring main unit is become with a segmentation group by two incoming line cabinets usually, must ensure in interlock protection in low voltage liaison net and main switch that two incoming line cabinets and these three switch cubicle of segmentation cabinet are in a dual-purpose standby state, namely only allow have two switch cubicles to be in "on" position simultaneously, 3rd switch cubicle must at gate-dividing state, to avoid causing paired running, existing ring main unit interlock often complex structure, safety and reliability have much room for improvement, in practice process, operating personnel are easy to misoperation occurs, the 3rd switch cubicle is caused to occur not right combined floodgate.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the simple and safe and reliable ring main unit of a kind of structure three close two procedure lock interlocks.
The technical solution adopted for the present invention to solve the technical problems is:
Three of a kind of ring main unit closes two procedure lock interlocks, comprise the three pieces of mounting panels be separately positioned on three switch cubicles, the isolating switch main shaft being arranged on the lock body on each mounting panel and being set on each mounting panel, a connecting axle is movably set with in described lock body, it is outer and be fixedly connected with a guide vane end stop that lock body is stretched out in described connecting axle one end, described isolating switch main shaft fixed sleeves is provided with upper limit cover, described three lock bodies configure two common key, when guide vane end stop and upper limit overlap coordinate time, described isolating switch main shaft locks and is not mounted opposite plate and rotates, switch cubicle is in "on" position, the key inserted in lock body can not pull out.
As the improvement of technique scheme, described guide vane end stop comprises the linkage section be fixed on connecting axle and the convex section installing linkage section lower end, described upper limit cover top is provided with recessed section along being interlinked to the outside in sidewall, and described key drives recessed section of convex section disengaging/holding respectively by rotating ON/OFF lock body.
As the improvement of technique scheme, described isolating switch main shaft is also fixed with lower limit cover, described mounting panel is folded between lower limit cover and upper limit cover.
Beneficial effect of the present invention has:
This interlock structure is simple, by upper limit cover and the cooperation locking isolating switch main shaft of guide vane end stop, two switch cubicles are made to be in "on" position, because three lock bodies only configure two common key, and switch cubicle is when being in "on" position, the key inserted in lock body can not pull out, and effectively prevents misoperation, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the invention will be further described, wherein:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structural representation of isolating switch main shaft in the embodiment of the present invention.
Embodiment
See Fig. 1, three of a kind of ring main unit of the present invention closes two procedure lock interlocks, the isolating switch main shaft 3 comprise the three pieces of mounting panels 1 be separately positioned on three switch cubicles, being arranged on the lock body 2 on each mounting panel 1 and being set on each mounting panel 1, a connecting axle 4 is movably set with in lock body 2, it is outer and be fixedly connected with a guide vane end stop 5 that lock body 2 is stretched out in connecting axle 4 one end, and guide vane end stop 5 comprises the linkage section 51 be fixed on connecting axle 4 and the convex section 52 installing linkage section 51 lower end.
With further reference to Fig. 2, isolating switch main shaft 3 fixed sleeves is provided with upper limit cover 6, upper limit overlaps recessed section 7 that 6 tops are provided with along being interlinked to the outside in sidewall, isolating switch main shaft 3 is also fixed with lower limit cover 8, mounting panel 1 is folded between lower limit cover 8 and upper limit cover 6, prevents isolating switch main shaft 3 to be mounted opposite plate 1 and moves up and down.
The misoperation of closing a floodgate to prevent switch cubicle, three lock bodies, 2 configurations, two common key, by rotate key operated/close atretic body 2 to drive convex section 52 to depart from/holding recessed section 7 respectively, when convex section 52 holding is in recessed section 7, isolating switch main shaft 3 is locked and is not mounted opposite plate 1 and rotates, switch cubicle is in "on" position, now, the key inserted in lock body 2 can not pull out, three lock bodies 2 making three switch cubicles corresponding only have wherein two can be closed by two keys, namely have in three switch cubicles and only have two to be in "on" position, reach safe and reliable standard.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should belong to protection scope of the present invention.
