Embodiment
As shown in Figs. 1-2, a kind of double power-supply automatic transferring with overlapping neutral function provided by the utility model
It switchs, including main shaft 8, gear-box 9 and driving motor 10, in gear-box 9 described in the output axis connection of the driving motor 10
Input gear, the output gear in the gear-box 9 connect the main shaft 8, and spacer sleeve is equipped with two rocker arms 7 on the main shaft 8, and two
The center line of the frontal plane of projection of the rocker arm 7 intersects, and one end of each rocker arm 7 connects the main shaft 8, and the other end passes through company
Bar 6 connects disconnecting link component, and two disconnecting link components are respectively set as common disconnecting link 1 and spare disconnecting link 2, commonly use disconnecting link 1 and spare disconnecting link 2
Two structures are identical.
Further, the disconnecting link component includes crossbeam 3 and contact plate 5, and the crossbeam 3 is under the action of connecting rod 6
Side-to-side movement, is equipped with contact bridge 4 on the crossbeam 3, the contact bridge 4 under the drive of the crossbeam 3 with the contact plate 5
Conducting and disjunction.
Further, the contact bridge 4 is made of the bridge that is in contact of A, B, C, N tetra-, and the contact plate 5 is by tetra- phase of A, B, C, N
Contact plate composition, described A, B, C, N tetra- be in contact bridge connect with A, B, C, N tetra- touch panel correspond.
Further, described A, B, C, N tetra- be in contact bridge spacing it is equal.
Further, described A, B, C connect the equal length of touch panel, and the connect length of touch panel of the N is greater than described A, B, C
Connect the length of touch panel.
Further, when the common disconnecting link 1 is in "on" position, the spare disconnecting link 2 is in gate-dividing state, similarly,
When the common disconnecting link 1 is in gate-dividing state, the spare disconnecting link 2 is in "on" position, the "on" position and gate-dividing state
It is realized by the conducting of the contact bridge 4 and contact plate 5 with disjunction.
As shown in Figs. 1-2, switch main body is made of mutually independent one common disconnecting link 1 and spare disconnecting link 2.Per disconnecting link all the way
There is a crossbeam 3 in shell, contact bridge 4, crossbeam 3 energy side-to-side movement, contact bridge 4 under the action of connecting rod 6 are installed on crossbeam 3
It is connected under the drive of crossbeam 3 with contact plate 5 and the function with disjunction power supply is connected in disjunction, realization.By driving when switch conversion
Motor 10 drives gear-box 9 to rotate, and the gear driving spindle 8 of gear-box 9 rotates, and has two mutually to form an angle on main shaft 8
Rocker arm 7, rocker arm 7 follow the rotation of main shaft 8 that connecting rod 6 is driven to move, and connecting rod 6 drives 3 side-to-side movement of crossbeam.Disconnecting link group as shown in Figure 3
In the "on" position and gate-dividing state of part: being above "on" position, be below gate-dividing state, A, B, C, N tetra- is in contact bridge
It is equal with contact plate spacing, and A, B, C accessible face length of touch panel and contact bridge that connects are also equal, but N connects the length of touch panel
Connect touch panel greater than A, B, C, so that N is in contact, bridge and contact plate can contact face and be greater than A, B, C phase.As shown in figure 4, when switch by
When common disconnecting link is converted to spare disconnecting link, the contact bridge of A1, B1, C1, N1 phase is moved downward with crossbeam 3, but N connects touch panel
It is greater than the disconnection stroke of A, B, C phase phase line contact plate and contact bridge with the disconnection stroke of contact bridge, when A1, B1, C1 phase phase line are disconnected
When opening, N1 phase is still contacted.The crossbeam 3 of spare disconnecting link moves right under the interlocking effect of rocker arm 7 and connecting rod 6 at this time, because of N phase
Combined floodgate stroke be less than phase line combined floodgate stroke, N2 be in contact bridge first contacted with contact plate.Disconnecting link continuation is commonly used at this time to transport to the left
Dynamic circuit breaker opens zero curve, and spare disconnecting link continues to move right phase line combined floodgate.Similarly it is spare to N1 phase when common conversion prior to A1, B1,
C1 phase is closed a floodgate, and in A2, B2, C2 separating brake after N2 phase, to realize that overlapping neutral is converted.
This structure is simple, easy for installation.A, B, C phase line are not limited only to lengthen contact plate with the nonsynchronous realization of N phase zero curve
Length, the length of contact bridge can also be lengthened or the two while being lengthened.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
