Specific embodiment
Multiple preferred embodiments of the invention are introduced below with reference to Figure of description, keep its technology contents more clear and just
In understanding.The present invention can be emerged from by many various forms of embodiments, and protection scope of the present invention not only limits
The embodiment that Yu Wenzhong is mentioned.
In the accompanying drawings, the identical component of structure is indicated with same numbers label, everywhere the similar component of structure or function with
Like numeral label indicates.The size and thickness of each component shown in the drawings are to be arbitrarily shown, and there is no limit by the present invention
The size and thickness of each component.Apparent in order to make to illustrate, some places suitably exaggerate the thickness of component in attached drawing.
One embodiment of the present of invention such as figure one: including change-over switch 1, change-over switch (2) and frame (3) are taken out.Change-over switch 1
It can shake into or shake out to the left or to the right by driving mechanism in taking out frame (3) with change-over switch (2)；
It is set as shown in Figure 1, change-over switch 1 shakes carry on right side, fixed outlet row 11,12,13 and pumping on change-over switch 1
The fixed line bank 51,52,53 of frame 3 is connected by touching bridge 31,32,33；
As shown in Fig. 2, change-over switch 1, which is located at left side, shakes out position, with outlet row 11,12,13 fixed on change-over switch 1
Touching bridge 31,32,33 on the line bank 51,52,53 fixed with frame 3 is taken out is discrete state, which can be from front
Extraction.Extraction state is as shown in Figure 3.
As shown in Figure 1, change-over switch (2) shakes carry in left side and sets, on change-over switch 2 fixed outlet row 21,22,23 with
The fixed line bank 51,52,53 of frame 3 is taken out to connect by touching bridge 41,42,43；
As shown in Fig. 2, change-over switch 2, which is located at right side, shakes out position, with outlet row 21,22,23 fixed on change-over switch 1
Touching bridge 41,42,43 on the line bank 51,52,53 fixed with frame 3 is taken out is discrete state, which can be from front
Extraction.
Such as Fig. 4, shown in Fig. 5, the fixed outlet row 11 with change-over switch 1,12,13, the fixed outlet row with change-over switch 2
21,22,23, the line bank 51,52,53 fixed with frame is taken out can have 1-4 phase as needed, a, b, c, n in corresponding circuits.
As shown in fig. 6, being circuit system state diagram, when change-over switch 1, when change-over switch 2 is in connection status, power supply 1
Power supply, change-over switch 2 are closed above, and electric current is touched bridge 41 by line bank 51, and outlet row 21 enters change-over switch 2, by turning
It changes switch 2 to flow out from outlet row 22, by touching bridge 42, reaches load outlet 52, give customer power supply.Change-over switch 1 is at this time
Gate-dividing state, no electric current pass through, therefore can extract maintenance or replacement out.
As shown in fig. 7, change-over switch 1 is closed, 2 separating brake of change-over switch, electricity when change-over switch 2 needs to safeguard or replace
The electric current in source 1 is touched bridge 31 by line bank 51, and outlet row 11 enters change-over switch 1, by change-over switch 1 from outlet row 12
Outflow reaches load outlet 52, gives customer power supply by touching bridge 32.Change-over switch (2) is in gate-dividing state at this time, without electricity
Stream passes through, therefore can extract maintenance or replacement out.
Usual bypass type change-over switch, one of change-over switch are fixed, and only a change-over switch can extract maintenance out,
The usual maintenance difficult when fixed change-over switch is problematic to be needed to safeguard, two change-over switches of the invention can extract dimension out
Shield, mutual backup substantially increase the maintainability of system.
