Working principle:
Described five anti-three station small size spring operating mechanisms first operate the switch operating shaft with exclusive operation handle,
Rotate clockwise 90 degree, the switch hand wheel is linked in switch operating shaft by retainingf key, operation shaft rear end with it is described
Pawl wheel is connected, and the outside acies of pawl wheel is connected with the switching-in spring, when the switch hand wheel rotates clockwise 90
When spending, the switching-in spring is stretched to certain length along the pawl wheel outer edge, and described five anti-three stations are small at this time
The stored energy operation of type spring operating mechanism is completed；
The mechanism driving unit further includes to five anti-three stations miniaturization operating mechanism closing operations, by described in rotation
Floodgate semiaxis, when the floodgate semiaxis rotates to fixed angle, the combined floodgate pulls son by the pressure rotation from cam
Certain angle, the rotation so that cam is taken advantage of a situation, the outer of cam and output toggle arm collide, and moment rotates output toggle arm and divided
Lock is removed sub- limit and is fixed, and when the output toggle arm rotates, will drive the fixed separating brake connecting lever of coaxial spline and acts together, and described point
Have on lock connecting lever and a little mutually mounted with the tripping spring, the tripping spring is stretched, and described five anti-three stations are small-sized at this time
Change spring operating mechanism operating mechanism unit and completes closing operation.
The operating mechanism unit further includes sub-switching operation: by rotating the separating brake semiaxis, when the separating brake semiaxis is revolved
When going to fixed angle, the tripping spring hauls the output toggle arm on coaxial, oppresses the separating brake support arm and rotates centainly
Angle realizes the sub-switching operation of the operating mechanism unit so that the output toggle arm rotates clockwise.
By closing isolated location to when dividing isolated location, the mechanism driving unit drives at switch the isolated operation unit
When gate-dividing state, the isolated operation wheel is rotated by 90 ° counterclockwise under the drive of operation handle, the isolated operation axis with
The isolated operation axis is fixedly connected by keyway, and realization rotates coaxially.The limit siding is just collided with the pawl shaft
When, the gap of the isolated operation wheel is just withstood on the vertex of the non-return pawl, and the position of the isolated operation axis is consolidated
It is fixed.The isolated operation unit is in earthing position at this time.When the isolated operation unit is isolated to conjunction isolated location by dividing, use
The operation handle is put into the isolated operation wheel, rotates clockwise 90 degree, the isolated operation wheel and the isolated operation
Axis rotates jointly identical angle, and the limit siding and the pawl shaft collide simultaneously, and the locking pawl just blocks
The isolated operation unit is fixed on and isolated location by isolated operation wheel.
The switch output board is rotated coaxially by keyway and output toggle arm, switchs side and the switch indicator board of output board
It is weldingly connected, is used to indicate the state of switch, the other side is connect with circuit breaker lock by pivot pin, and the circuit breaker lock one switchs defeated
Ejecting plate connecting side has strip notch, and middle position is fixed with side plate, forms rotation basic point, and the switch driving unit is closed
During lock operates, the circuit breaker lock of the chain indicating unit can be with certain angle be rotated, by the isolated operation
The limitation of unit handle hole, prevents the isolated operation unit from operating.It is described when the switch driving unit is in gate-dividing state
Isolation drive unit can be arbitrarily switched closing isolation with a point isolation.The isolation indicator board and isolated operation wheel pass through limit
Position slot and bolt are fixed, and are rotated both along the identical center of circle, and the other end of indicator board and the chain instruction for having notch is isolated
It is slidably connected, realizes slide handover of the instruction switch between main switch and earthing switch, the isolated operation unit is in
When conjunction state, isolation indicator board display is closed, and chain instruction shows main switch state；The isolated operation unit is in isloation state
When, interlocking instruction display earthing switch state.When being shown as ground state at the switch driving unit and being in "on" position
Lower gate interlock can be operated, Xiamen is taken, the top plate moves up, and switch can not carry out separating brake, installs down behind the door, top plate
Playback, can carry out breaking-closing operating.The switch driving unit is in conjunction state, and isolated operation unit is in conjunction state, at this time
Switch is in "on" position, and ground connection is closed, and after the switch carries out separating brake, the isolated operation unit carries out a point operation, opens at this time
It closes and is in separating brake, isloation state is isolated, main switch state is switched to earthing switch state, and the switch driving unit carries out combined floodgate behaviour
After work, the switch driving unit is in contact of earth state, and the isolated operation unit, which is in, closes ground state.Realize three works
Conversion between position.
The advantage is that: it is compact-sized, small in size, operation expense is low, combination is convenient, the anti-interlock that has five,
It is with isolator operating mechanism and can significantly reduce electric power facility investment.
