Embodiment
Further illustrate with reference to accompanying drawing 1 to accompanying drawing 3 pairs of the utility model indoor high-voltage vacuum on-load switches.
A kind of indoor high-voltage vacuum on-load switch 4, comprise framework 1 and be fixed on isolating switch 2, on-load switch 4 and the earthed switch 3 on framework 1, described isolating switch 2 and earthed switch 3 link, and earthed switch 3 separating brake during isolating switch 2-in-1 lock, during isolating switch 2 separating brake, earthed switch 3 closes a floodgate.Described isolating switch 2 comprises isolation axle 21, described earthed switch 3 comprises grounding shaft 31, be provided with earthed crank arm 34 between described isolation axle 21 and grounding shaft 31, isolate connecting lever 24 and linking arm 8, described earthed crank arm 34 and isolation connecting lever 24 are respectively with grounding shaft 31 with isolate axle 21 and be connected, the two ends of described linking arm 7, respectively with earthed crank arm 34 with isolate connecting lever 24 hinged, described isolation axle 21, isolate connecting lever 24, linking arm 8, earthed crank arm 34 and grounding shaft 31 and link successively.Described insulating cover 6 comprises housing 61 and cover plate 62, and described housing 61 is fixedly connected with framework 1, and described cover plate 62 is with bolts with housing 61.Described insulating cover 6 adopts carbon moulding material to make.Setting up of insulating cover 6 makes isolating switch 2 have good anti-tracking effect.
Described on-load switch 4 comprises operating axis 41, and described operating axis 41 one end is provided with spacing catch 11, framework 1 is provided with limited protruding member 5, described spacing catch 11 and limited protruding member 5 clamping.Described spacing catch 11 comprises rotating forward stopper 111 and reversion stopper 112.Described isolating switch 2 also comprises isolation knife 22 and isolated port 23, described earthed switch 3 also comprises earthing 32 and grounding ports 33, described isolated port 23 is all fixedly connected with framework 1 with grounding ports 33, and described isolation knife 22 and earthing 32 are connected to isolation axle 21 and grounding shaft 31.
In sum, such setting can make isolating switch 2 and earthed switch 3 link, when the 2-in-1 lock of isolating switch, and earthed switch 3 separating brake, when isolating switch 2 separating brake, earthed switch 3 closes a floodgate, and concrete when isolation knife 22 is connected with isolated port 23, isolating switch 2 of the present utility model is "on" position, now earthing 32 and grounding ports 33 are separately, namely earthed switch 3 separating brake, can realize anti-misoperation like this, improves the safety index of operating personnel.
The utility model, under normal circuit condition, can close, carries and cut-off load current, can close short circuit current, and has the ability of carrying short circuit current at the appointed time; The environment for use condition height above sea level be suitable for is not more than 1000 meters, and ambient temperature is up to 40 degrees Celsius, and minimum temperature is subzero 25 degrees Celsius, and relative humidity daily mean is not more than 95 percent, and monthly average value is not more than 90 percent; Earthquake intensity is no more than eight grades; Requirement for environmental conditions is non-corrosiveness gas, imflammable gas, significantly water vapour and the place without regular strenuous vibration.So the utility model is suitable for being arranged in the switch cubicle of loop-network switch cabinet, box-type substation and housing type thereof, because having stronger connecting-disconnecting function, be the ideal product of current power distribution network, transformer and distribution power station, the construction of switching station, transformation, renewal, be widely used in during factory, school, hotel, market, residential quarters etc. build.
The utility model adopts framework 1 formula structure, integrates isolating switch 2, on-load switch 4, earthed switch 3, stored energy mechanism, tripping mechanism.Isolating switch 2, on-load switch 4, earthed switch 3 from top to bottom set gradually, and vacuum interrupter, isolating switch 2 fixed contact are arranged on insulating base, and three phase isolated effect bolt is separately fixed on framework 1.
Switch adopts twin shaft operation, and vacuum switch adopts an operating axis 41 to carry out divide-shut brake, can adopt electronic or manual mode.Isolating switch 2 shares an operating axis 41 with earthed switch 3, only can use manual operation, and isolating switch 2 and earthed switch 3 link, and namely when isolating switch 2 separating brake, earthed switch 3 closes a floodgate, earthed switch 3 separating brake when isolating switch 2-in-1 lock.
Must check deciliter state of switch before operation from panel, the isolating switch 2 when dispatching from the factory is in open position, and namely vacuum interrupter is in open position, when on-load switch 4 is when closing a floodgate, grounding shaft 31 braked by interlock, and earthed switch 3 cannot close a floodgate, thus prevents misoperation.
Closing operation: first must be shut by cabinet door, then lock door lock by operating axis 41, earthed switch 3 separates, on isolating switch is 2-in-1.If employing closing by hand, handle should be inserted upper shaft hole, sub-switching operation when closing a floodgate: if with electronic, by opening button; If with manual operation, then by handle attended operation axle 41, be rotated counterclockwise certain angle, after hearing separating brake sound, operating grip can not stop, and should continue to be rotated counterclockwise on earth.
When earthed switch 3 separating brake, cabinet door lock closes, the 2-in-1 lock of isolating switch, otherwise when earthed switch 3 closes a floodgate, cabinet door is opened, isolating switch 2 separating brake, to ensure the fail safe of operating personnel.
Compare original vacuum load switch for household, what its isolating switch 2 adopted is direct-push, and in the utility model, and the form of what isolating switch 2 adopted is inclined push type, inclined push type is compared and directly pushed away is to strengthen isolation effect.Described isolating switch 2 links with earthed switch 3, and isolating switch 2 is contrary with earthed switch 3 divide-shut brake situation.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
