The fixed part connection of connector, connects control loop, can carry out remote control, body is operated by controller to test
Function debugging, the various functions of detection switch body and controller.
The specifically used process of the application is as follows：
Under normal circumstances, the first locking part 31 pins slide plate 8,30, and sledge displacement locking will not be slided because of transport etc.
Artificial situation, presses button 32,40, and the first locking part 31 is unlocked, and slide plate 8,30 and guide plate 7,26 are extracted out, pulling guide plate 7,
26 when arriving the end of a period of stroke, and the first locking part 31 on slide plate pins the position of slide plate 8 and guide plate 7, and plate 26 and 30 is also same
Reason, now drawer chassis is ready, can bear the placement of Switch main body 2.
Switch main body 2 is placed on slide plate 7 and 26, the roller 33 on Switch main body depresses the projection of the first locking part 31
Place, the interlocking between slide plate 8,30 and guide plate 7,26 is unlocked, now pushing plate 7,26, then whole skateboard component and Switch main body 2 one
Drawer chassis can be pushed into by rising, at the end of stroke, and the first locking part 31 pins another button 40, opposite side be also in this way, this
Shi Benti and drawer chassis are in separation point position, are that the connection of automatic change-over and power supply and load is got ready.
Operation handle 41 is taken out, in the hole for inserting screw rod 19, after hand screw rod, passes through fortune of the screw rod between slide plate top nut
It is dynamic to promote skateboarding, and drive the sector gear 20 engaged with slide plate to rotate, and then the rotation of rotary shaft 21 is realized, turning
The two ends of moving axis 21, are connected with connecting rod 38 and are connected with long guide rod 22, the other end of long guide rod 22 is connected with cam 24, rotary shaft
21 rotation has just driven the ball 23 on the rotation of cam 24, slide plate 7 to be located in the groove of cam 24, thus the rotating band of cam
The motion of slide plate has been moved, motion of the body in drawer chassis is realized.Now, locking part 44 lays the blocking lever of body, it is ensured that
Body is in gate-dividing state, it is ensured that the safety of operating personnel.The fixed part 15 of secondary plugging-in element is arranged on drawer chassis, and this is consolidated
Fixed part is connected with remote control split-phase, when the position of body and drawer chassis is in testing position, two installed on body
The motion parts of secondary connector and the fixed part of secondary plugging-in element are connected, due to the movable portion of the secondary plugging-in element on body
Divide and be connected with controller, auxiliary switch, closing electromagnets 14, motor, shunt release, so, remote control loop
It is electrically connected with controller, auxiliary switch, closing electromagnets, motor, shunt release etc., remote control can be carried out, to try
Test the debugging for the various functions that body is operated by controller.The side plate of drawer chassis is connected with underframe, and underframe is by shield door, bridge
The external parts of busbar 29 3 composition of shape contact (also referred to as bridge type chuck) 28, when the relative position of body and drawer chassis be in separation and
During testing position, shield door is closed, it is ensured that no matter body is combined floodgate or sub-switching operation, is all isolated with power supply and load end, really
Protect the safety of operating personnel；When body is moved from testing position to link position, the locking part 44 of side plate is laid on body
Blocking lever realizes the separating brake of body, and now shield door is opened, and body busbar is connected with bridge-shaped contact, connected by bridge type busbar
To mains side and load-side, when body and drawer chassis position are located at and be reliably connected, the interlocking 44 of body and drawer chassis is unlocked, right
Body carries out closing operation, and switch is in normal working condition.
When need to drag body from drawer shake out when, reverse swinging handle, it is ensured that Switch main body separating brake, operator can be safe
Reliably operated, in testing position, can detect each function it is whether normal, failure judgement reason, need change and
During maintenance, continue to shake out to separation point position, press button 32,40, by the interlocking unblock in side plate, pull out slide plate to the weight of stroke
Point position, completes the replacing of body.In whole process, the bus-bar of drawer chassis is connected with power supply, load all the time, does not influence it
The normal work of his appliance component.
