U, the head end (U1, V1, W1) of V, W, tail end (U2, V2, W2) form the low of standard by star breaker 2 (Y MCB) short circuit
Pressure starts star circuit connection mode；Meanwhile the drive shaft 5 drives the protruding parts of first handle axis cam 4a and first to take off
The upper end of button driving lever 4c disengages, and the first contact pilotage 4e on the first dropout driving lever 4c relieves the conjunction of diametrical connection breaker 3
Lock limits.After rotor smooth running, corner connection breaker 3 (△ MCB) starts to close a floodgate, and corner connection breaker 3 is extremely breaking by three
Device forms, and inside is also to be concatenated by a three pole drive shafts 8, after 3 feed motion of corner connection breaker starts, 8 band of drive shaft
The protruding parts of dynamic second handle axis cam 4b starts to oppress the second dropout driving lever 4d upper ends, and the on the second dropout driving lever 4d
Two contact pilotage 4f start to fire the tripping mechanism that the star connects breaker 2, and star is made to connect breaker 2 and is disconnected so that the present invention is in machinery
It ensure that three pairs of contacts of corner connection breaker 3 in structure before splicing, star connects breaker 2 and disconnects in advance, and motor passes through at this moment
After crossing of short duration power-off inertia operation, corner connection breaker 3 is connected quickly, and motor enters normal high pressure (line voltage) operating condition.
The course of work of three phase alternating current motor star angle switch starter of the present invention is as follows：
1st, motor star-like connection low voltage starting：Master control driver 6 starts to drive sextupole drive shaft 5 to rotate or straight manually
It connects and pulls sextupole co-acting lever 7 and close a floodgate, main circuit is connected, three winding tail ends of motor are short-circuit (linking together), and motor is realized
Star-like connection low-pressure operation.Meanwhile first handle axis cam 4a (based on Fig. 2 projecting directions) is driven by sextupole drive shaft 5
Positive hour hands rotate so that the contact with the first dropout driving lever 4c of the protruding parts of first handle axis cam 4a is converted into first handle
The contact with the first dropout driving lever 4c of the depressed area of axis cam 4a, the first dropout driving lever 4c are released from oppressing, and first touches
Pin 4e returns to unlocked position (unlock is the releasing combined floodgate limitation for corner connection breaker 3).
2nd, motor is transformed into normal high pressure delta connection state：After motor low pressure star-like connection smooth running,
Automatically controlled driver 9 starts that three pole drive shafts 8 is driven to rotate or directly pull three pole co-acting levers 10 manually and close a floodgate, with three poles
The three pole drive shafts 8 that co-acting lever 10 links drive second handle axis cam 4b so that the protrusion of second handle axis cam 4b
Position presses the upper end of the second dropout driving lever 4d, and the second contact pilotage 4f on the dropout driving lever 4d is caused to trigger star and connects breaker 2
Tripping mechanism, this moment, the feed motion of three pole co-acting levers 10 is still among the halfway of movement, but the second contact pilotage 4f has been incited somebody to action
The contact that star connects breaker 2 disconnects, although machine winding circuit is cut off at this time, due to rotor and the inertia of mechanical equipment
Effect, motor are operating at this time by inertia completely, and this of short duration power-off interval is necessary, and two are ensure that from mechanical structure
The order of kind winding connection.Motor is after of short duration power-off coasting, and three pole co-acting levers, 10 feed motion is whole quickly
It completes, machine winding realizes triangle connection, and motor enters normal high pressure corner connection operating status.It needs exist for illustrating
Although this clock star connects 2 breaking of breaker, from the appearance less than handle breaking, its handle is broken with main switch
Road device 1 is connected as a single entity, and main switch breaker 1 is still within closing position, this is because star connects breaker 2 and main switch breaker
Without dropout interlocking mechanism between 1, even if the star connects 2 dropout breaking of breaker, main switch breaker 1 still maintains combined floodgate shape
State, the breaking that the star connects breaker 2 are also only that inside contact disconnects.
3rd, motor shuts down：When work stop or machine an emergency situation is encountered need cut off motor power, the present invention
It can be realized by several ways.The first, main automatically controlled driver 6 is internally provided with electromagnetic release mechanism, can be by wired
Or wireless stop button, 1 electromagnetic trip breaking of triggering main switch breaker, while pass through sextupole drive shaft 5, first-hand arbor
Cam 4a, the first dropout driving lever 4c, the first contact pilotage 4e, triggering corner connection breaker 3 tripping mechanism breaking together；Second, pressing
Manual scram button 4g or 4i by pressing scram button 4g or 4i, promotes swing rod, swing rod drives the first dropout driving lever 4d simultaneously
It is rotated counterclockwise with the second dropout driving lever 4c so that 4e and 4f on the dropout driving lever move right, and triggering star connects breaker 2
With corner connection breaker 3 while breaking of threading off, three winding circuits of motor are cut off, and electric current induction coil 11 is non-inductive, master control
1 electromagnetic trip breaking of driver automatic trigger main switch breaker；The third, directly pulls lower sextupole co-acting lever 7 manually, as before
It is described, except six grades of linked circuit breaker breakings itself described, also pass through the sextupole drive shaft 5, first handle axis cam 4a,
One dropout driving lever 4c, the first contact pilotage 4e, the triggering corner connection breaker 3 are threaded off, final to cause three groups of totally nine pole breakers wholes
Breaking powers off.
4th, original state is recovered：By above-mentioned process 3, motor shuts down, and all breakers, which empty back into, disconnects position
It puts, at this point, the first handle axis cam 4a (based on Fig. 2 projecting directions) inside converter 4 is by rotating counterclockwise so that
The protruding parts of first handle axis cam 4a contacts with the first dropout driving lever 4c upper ends and (oppresses the position of the first dropout driving lever 4c
Put), the first contact pilotage 4e on the first dropout driving lever 4c is moved back into the right the tripping mechanism for withstanding corner connection breaker 3 so that corner connection
