Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
The drawout chassis of automatic transfer switching electric appliance of the present invention, emphasis ensures the reliable fit with Switch main body.The drawout chassis of automatic transfer switching electric appliance as shown in Figure 1, comprises the pedestal 7 of drawout chassis framework 6 and drawout chassis framework 6 inboard, and described pedestal 7 is fixed with outgoing line busbar 4, and bridge-type contact 3 is arranged on outgoing line busbar 4, and bridge-type contact 3 socket outwardly; Described drawout chassis framework 6 is provided with socket second loop return wiring terminal 5 outwardly; Be provided with guide rail 2 inside drawout chassis framework about 6 two, the other instruction push rod 8 being provided with inductive switch body insertion depth of guide rail 2, instruction push rod 8 is connected to the instruction slide block 1 on drawout chassis framework 6 by link gear.Switch main body inserts along guide rail 2 and extracts, instruction push rod 8 is along with the insertion depth generation displacement of Switch main body, Switch main body is position one when not inserting drawout chassis framework 6, be position two when second loop return wiring terminal 5 on the second loop return wiring terminal insertion drawout chassis framework 6 of Switch main body and the outgoing line busbar of Switch main body do not insert bridge-type contact 3, be position three when second loop return wiring terminal 5 on the second loop return wiring terminal insertion drawout chassis framework 6 of Switch main body and the outgoing line busbar of Switch main body insert bridge-type contact 3, correspondence position one, position two and position three, described instruction slide block 1 moves to respectively " to be separated, experiment, connecting " three positions indicate.On drawout chassis framework 6, these three positions of corresponding instruction slide block 1 have mark " to be separated, to test, connect " printed words respectively, make people very clear.
The work of instruction push rod 8 as shown in Figure 5, instruction push rod 8 is arranged on drawout chassis framework 6 by axle 9, spring 10 one end is fixed on drawout chassis framework 6, the other end connects instruction push rod 8, instruction push rod 8 pivots and needs to overcome spring 10 pulling force, when Switch main body (not shown) is moved along guide rail 2, the keeper 12 of Switch main body both sides promotes instruction push rod 8 and rotates displacement, when to three different location statuss, instruction push rod 8 and keeper 12 are formed and coordinate and determine a position, are indicated by instruction slide block 1.The pulling force that spring 10 mainly gives instruction push rod 8 certain, ensures that instruction push rod 8 puts in place, and prevents spring.When Switch main body is extracted, instruction push rod 8 return-to-home position under the pulling force of spring 10.
All install the guide rail 2 cooperatively interacted on Switch main body He on drawout chassis, the motion of Switch main body all moves back and forth on guide rail 2; As shown in Figure 2, limited location breaker slot 11 on guide rail 2, is braked by handle limited in different positions, makes the locating part on Switch main body be stuck in spacing breaker slot 11; The display instruction slide block 1 be mounted on drawout chassis of diverse location has slided up and down, and follows the change in location of Switch main body and changes.In different positions, there is obvious instruction, convenient operation and debugging.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 with the use of, patch as shown in Figure 4, the wiring that Convenient switch is inside and outside, freely, Switch main body does not need to regulate original distribution after separating in plug.Outgoing line busbar and the second loop return wiring terminal of Switch main body are followed the motion of Switch main body and move, the direction of motion and stroke completely the same, such guide rail, position display and second loop return wiring terminal formed one, carried out three position functions.During " experiment " position, secondary circuit is connected, major loop access failure; During " connection " position, secondary circuit is all reliably connected with major loop.
The connection of switch major loop has been come by bridge-type contact 3, outgoing line busbar 4 is fixed on the pedestal 7 of drawout chassis, that level aligns with the outgoing line busbar of Switch main body, bridge-type contact 3 is arranged on the outgoing line busbar 4 of drawout chassis, with Boards wall and can rock by low-angle up and down, ensure that insertion is extracted by resistance; The cooperation of outgoing line busbar 4 and bridge-type contact 3 is as Fig. 3.The position of inserting is decided by Switch main body, as long as the stroke calculating link position is just passable, the pressure of connection and contact area are all determined by special bridge-type contact 3.Bridge-type contact 3 is primarily of upper and lower mounting panel, contact blade and spring composition, and two in the face of inserting busbar.Insert the thickness of busbar, width is different, the number of contact blade is all different with the rigidity of spring, the bridge-type contact that often kind of specification current class is installed is different, adjustment contact pressure and contact area, ensure the operating temperature rise of switch and specified current capacity, the connection of switch and breaking capacity, reach electrical performance demands.Such structure installment is convenient, and plug position is accurate, and ensure that contact is reliable by spring, contact resistance is little, and temperature rise is low.
Operation principle of the present invention is substantially identical with existing intelligent universal circuit breaker technology, the structure improved mainly ensures three position situations of major loop and secondary circuit, the connection of convenient and reliable disconnection major loop, do not affect the complete sets of equipment, completely Switch main body and the complete sets of equipment are separated, be convenient to user carries out this position operation in body position, safe and reliable, easy to operate.
The present invention reliably to be inserted by Switch main body by guide rail and extracts, also the location of Reliable guarantee diverse location, the important point is also had to be without securing member to carry out the connection of major loop wiring bus-row, and form cooperation by bridge-type contact and outgoing line busbar, this group structure determines the depth inserted by the stroke of Switch main body, the contact area of bridge-type contact and the size of spring pressure ensure electric property, have lower temperature rise, reliable making capacity when normal work.Second loop return wiring terminal facilitates wiring, and the motion of Switch main body does not affect the distribution of the control loop inside and outside switch, and and three position consistency of Switch main body, the electric function of diverse location is different, ensure that safety when maintenance and debugging and work.
Structure of the present invention, flexibility and reliability is extracted in the insertion that switch grace is replaced, ensure reliable electric property, the reliable contacts of bridge-type contact and outgoing line busbar, when normal work, temperature rise is low, and current capacity is strong, and switch does not occur bad phenomenon when connection and disjunction, comprise the phenomenons such as sparking and melting welding, be convenient to user's maintenance and debugging.
