Description
The utility model belongs to the actuating system of power switch, and this programme relates to the improvement of stored energy mechanism in its actuating system.
Vacuum switch is that vacuum circuit-breaker is a kind of switchgear of novel electric power system, it be by the vacuum interrupter that has switch contact and drive the contact branch, the actuating system that closes constituted.This type of switchgear electric power systems of using at high voltage, big electric current more, characteristics for this reason, it require contact branch, close and will have certain strength and speed.The actuating system Will of general vacuum switch adopts the mechanically operated pattern of spring energy-storage.The spring energy-storage actuating system of the CTB type switch that China produces is exactly a kind of typical mechanism.Its structure such as Fig. 2 (see the 203rd page of (vacuum switch) book, China Machine Press published in 83 years).It is to stir with driven by shaking gear 7 or palm hand lever 10 or with motor-driven to drive ratchet 12, ratchet 3 is rotated, drive eccentric pin with 2 energy storage of combined floodgate energy-stored spring, when energy storage axle 14 turns over about 190 °, drive plate 15 on the ratchet is thrown off ratchet and ratchet, kept the restriction of energy storage state machine keeper 16 with the roller 17 on the cam 18 on the coaxial ratchet, though under the spring tension effect, can not be rotated further.When needs close a floodgate, switching signal makes making electromagnet 23 actions, through rod member 25,29, the restriction that 17 pairs of cams of keeper 18 rotate has been removed in 30 transmission, cam is made clockwise direction near 170 ° rotation under the tension of the switching-in spring 2 of energy storage, the roller 19 experience cam descendings that contact with cam and two sections motions of upward slope, do counterclockwise to rotate by connecting plate 26 pulling fanning strips 27 during descending, after fanning strip passes through the restriction arcwall face of semiaxis 24, semiaxis rotates counterclockwise, fanning strip is blocked, when the upward slope of roller experience cam during the stage with roller 19 to extrapolation, the connecting lever 38 of connecting rod 20 and one, 11 rotate counterclockwise, and the pull bar 32 of arc control device is led in pulling, make the contact contact of vacuum interrupter, finish feed motion, make tripping spring 31 distortion and the energy storage on the connecting lever simultaneously.When the needs separating brake, control electromagnet 22 actions that divide gate controlling mechanism, upwards evading buckle 21 makes semiaxis 24 do that clockwise direction rotates and removes restriction to fanning strip, four-bar mechanism becomes the state that moves about of five-rod, connecting lever 11 clockwise rotates under the effect of the tripping spring of energy storage, the pull bar 32 that leads to arc control device is set back contact is disconnected, finish the action of separating brake.This mechanism can finish the energy storage of switching-on mechanism, can finish feed motion to behind the switching signal, can finish the action of separating brake behind the given sub-gate signal.If behind combined floodgate, enter the energy storage state again, electromagnet 22,23 is done the contact that outside timeliness circuit is controlled, can also finish the automatic reclosing action.Though the equipment function of this CTB and modification thereof is more complete, its combined floodgate stored energy mechanism complexity, slow motion during with the driven by shaking gear, need to rotate a lot of circles, need the plate several times with handle 10 energy storage, just can finish the energy storage action.Because complex structure, potential fault is also many.
The purpose of this utility model provide a kind of speed fast, be convenient to operate and closing by hand stored energy mechanism that fault is few.
By following design, the manual energy storage switching-on mechanism of vacuum circuit-breaker actuating system provided by the utility model is by driving stored energy mechanism, drive the cam link mechanism of separating brake, feed motion, energy storage maintaining body and divide gate controlling mechanism to form, its concrete feature are that its driving stored energy mechanism is made up of manual plate handle, sprocket wheel, chain and the sprocket wheel that has a freewheel clutch.The core of freewheel clutch and divide-shut brake cam are fixedly mounted on the same axle, and chain couples together two sprocket wheels, and manually the plate handle is fixedly connected with sprocket wheel.Freewheel clutch is driving condition in the direction of the clock on camshaft.
Freewheel clutch in this closing by hand stored energy mechanism adopts the bicycle freewheel of 18 teeth.
On the basis of the actuating system of former CTB switch and modification thereof, adopt the closing by hand stored energy mechanism of this programme, with two sprocket wheels, chain, plate and freewheel clutch can replace original ratchet, ratchet and drive one of ratchet motion overlapping mechanism.Mechanism simplifying, fault also greatly reduce.Hand is pulled handle during use, drive sprocket, pass to the axle of band freewheel clutch sprocket wheel through chain, by clockwise rotating is driving condition, the palm handle once just can be finished the action of energy storage, kept the restriction of energy storage state machine can maintain the energy storage state of combined floodgate, when obtaining the above-mentioned restriction cancellation of switching signal, cam clockwise rotates under the pulling force of combined floodgate energy-stored spring, finish the action of combined floodgate, clockwise rotating of camshaft self is the restriction that is not subjected to freewheel clutch, also can not cause the motion of manual handle.The action of its separating brake is identical with former CTB type switch, if enter the energy storage state again after closing a floodgate, and will close a floodgate, circuit that two control electromagnet of separating brake are made external time property controls, and also can finish the action of automatic reclosing.
The superiority that adopts this programme to embody: 1. compare with CTB type operating mechanism, function is constant, but has simplified mechanism, has reduced manufacturing cost; 2. simple to operate, action is fast, pulls manual handle and once just can finish the energy storage action; 3. safe, because the single effect of freewheel clutch, therefore the action of closing a floodgate can not have influence on outside handle; 4. reduced the fault of stored energy operation system.
