Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
The drawout chassis of the automatic transfer switching electric appliance of the present invention, emphasis is to ensure that the reliable fit with Switch main body.As Fig. 1
The drawout chassis of shown automatic transfer switching electric appliance, including the pedestal 7 of drawout chassis framework 6 and drawout chassis framework 6 inboard, described base
It is fixed with outgoing line busbar 4, bridge-type contact 3 is arranged on outgoing line busbar 4, and bridge-type contact 3 socket is outwardly on seat 7；Described drawout chassis
Socket second loop return wiring terminal 5 outwardly is provided with framework 6；Inside drawout chassis framework 6 about two, guide rail 2 is installed, leads
The instruction push rod 8 of inductive switch body insertion depth is installed by rail 2, instruction push rod 8 is connected to drawout chassis by link gear
Instruction slide block 1 on framework 6.Switch main body is along guide rail 2 into and out instruction push rod 8 is with the insertion depth of Switch main body
Produce displacement, Switch main body is not inserted into during drawout chassis framework 6 being position one, the second loop return wiring terminal insertion of Switch main body is taken out
The outgoing line busbar of second loop return wiring terminal 5 on drawer seat frame frame 6 and Switch main body is not inserted into during bridge-type contact 3 being position two,
The second loop return wiring terminal of Switch main body inserts going out of second loop return wiring terminal 5 on drawout chassis framework 6 and Switch main body
It is position three during line busbar insertion bridge-type contact 3, correspondence position one, position two and position three, described instruction slide block 1 moves respectively
Indicated to " separate, test, connecting " three positions.On drawout chassis framework 6, these three positions of corresponding instruction slide block 1 are divided
There is not mark " separate, test, connecting " printed words, make people very clear.
Indicate the work of push rod 8 as shown in figure 5, instruction push rod 8 is arranged on drawout chassis framework 6 by axle 9, spring 10 1
End is fixed on drawout chassis framework 6, and the other end connects instruction push rod 8, and instruction push rod 8 pivots and needs to overcome spring 10 to draw
Power, Switch main body（In figure is not shown）Along guide rail 2 move when, the keeper 12 of Switch main body both sides promotes instruction push rod 8 to occur
Swing offset, when the location status different to three, instruction push rod 8 and keeper 12 form and coordinate and determine a position,
Indicated by indicating slide block 1.The certain pulling force of instruction push rod 8 mainly given by spring 10 it is ensured that instruction push rod 8 puts in place, and prevents
Spring.When Switch main body is extracted, indicate push rod 8 return-to-home position under the pulling force of spring 10.
The guide rail 2 cooperating all is installed on Switch main body and on drawout chassis, the motion of Switch main body comes all on guide rail 2
Backhaul dynamic；As shown in Fig. 2 limited location breaker slot 11 on guide rail 2, braked by handle limited in different positions, make Switch main body
On locating part be stuck in spacing breaker slot 11；The display of diverse location is mounted in glides on the instruction slide block 1 on drawout chassis
Dynamic complete, follow the change in location of Switch main body and change.In different positions, there is obvious instruction, be easy to operate and adjust
Examination.Second loop return wiring terminal divides two parts, and a part is arranged on drawout chassis, and a part is arranged on Switch main body, they
Use cooperatively, patch as shown in figure 4, the inside and outside wiring of Convenient switch, freely, Switch main body is separate for plug
Do not need afterwards to adjust original distribution.The outgoing line busbar of Switch main body and second loop return wiring terminal follow the motion of Switch main body
And move, the direction of motion and stroke are completely the same, and such guide rail, position display and second loop return wiring terminal form one, come
Complete three position functions.During " experiment " position, secondary circuit is connected, major loop access failure；During " connection " position, secondary circuit and
Major loop is all reliably connected.
Switch major loop connect through bridge-type contact 3 to complete, outgoing line busbar 4 is fixed on the pedestal 7 of drawout chassis
On, and the outgoing line busbar of Switch main body is that level aligns, bridge-type contact 3 is arranged on the outgoing line busbar 4 of drawout chassis, uses clamping plate
Fixing and low-angle can rock and be not subject to resistance it is ensured that inserting and extracting up and down；The cooperation of outgoing line busbar 4 and bridge-type contact 3 is such as
Fig. 3.The position of insertion to be determined by Switch main body, as long as calculating stroke just permissible, the pressure of connection of link position
Power and contact area are all to be determined by special bridge-type contact 3.Bridge-type contact 3 is mainly by upper and lower installing plate, contact blade and bullet
Spring forms, and two in the face of inserting busbar.The insertion thickness of busbar, width are different, contact blade number and spring rigidity all different, often
The bridge-type contact that kind of specification current class is installed is different, and adjustment contact pressure and contact area are it is ensured that the work of switch
Make temperature rise and specified current capacity, the connection of switch and breaking capacity, reach electrical performance demands.Such structure installation side
Just, by spring, plug position accurately, ensures that contact is reliable, contact resistance is little, and temperature rise is low.
The operation principle of the present invention is essentially identical compared with intelligent universal circuit breaker technology, and improved structure is mainly
Ensure three position situations of major loop and secondary circuit, the connection of convenient and reliable disconnection major loop, do not affect complexes, complete
Full Switch main body and complexes are separated, be easy to the operation that user carries out this position in body position, safe and reliable, behaviour
Facilitate.
The present invention pass through guide rail by Switch main body reliable into and out, the also positioning of Reliable guarantee diverse location, also
It is important that to carry out the connection of major loop wiring bus-row without securing member, and pass through bridge-type contact and outgoing line busbar shape
Become cooperation, this group structure determines the depth, the contact area of bridge-type contact and the spring pressure of insertion by the stroke of Switch main body
The size of power ensures electric property, has relatively low temperature rise, reliable making capacity in normal work.Second loop return wiring terminal
Facilitate wiring, the motion of Switch main body does not affect to switch the distribution of inside and outside control loop, and three positions with Switch main body
Unanimously, the electric function of diverse location different it is ensured that safety when maintenance and debugging and work.
, so that flexibility and reliability is extracted in the insertion that switch grace is replaced it is ensured that reliable electric property, bridge type touches for the structure of the present invention
Head and the reliable contacts of outgoing line busbar, in normal work, temperature rise is low, and current capacity is strong, and switch occurs without in connection and disjunction
Bad phenomenon, including phenomenons such as sparking and melting welding, is easy to user's maintenance and debugs.
