During the electromagnet power-off of transverse slider, because of the reset response placed in the middle of its electromagnet, transverse slider is intended to lean-with
Put；Because of releasing magnet reset response, longitudinal sliding block is intended to front end；Longitudinal sliding block is driven when releasing magnet is powered backward
Move and completely disengage from transverse slider, now transverse slider can be reset to center condition；When transverse slider is reset to center condition,
Left and right moving touch article thereon departs from corresponding stationary contact；
When transverse slider is placed in the middle, longitudinal sliding block groove can fully-inserted transverse slider groove, now on longitudinal sliding block
Dynamic touch article turns on the stationary contact of front end；
During transverse slider is driven to left side sometime, the dynamic touch article in the driving of spring one left side on transverse slider
Start to contact and turn on the corresponding stationary contact in left side, as transverse slider continues to be moved to the left, spring one continues to be compressed, and works as horizontal stroke
When stopping mobile to sliding block, spring one is by compression m；Solenoid actuated transverse slider is moved to after left side, and releasing magnet breaks
Electricity, longitudinal sliding block forward end resets, and longitudinal sliding block groove is inserted in transverse slider Right Border (because of the limitation of transverse slider Right Border
There is electrical safety distance between dynamic touch article and its front end stationary contact on longitudinal sliding block return stroke, longitudinal sliding block, i.e., longitudinal direction is sliding
Mechanical switch on block is still within off-state), the now lateral surface of transverse slider groove left frame and longitudinal sliding block groove
The spacing of left frame medial surface is n (m>n)；When transverse slider electromagnet is powered off, transverse slider resets to middle position, but by vertical
N can only be resetted to the effect of slip recess and stops and is in stability, while the spring one on transverse slider is also multiple
Position n；Because m>N, spring one is still by compression m-n, and the elastic force that decrement (m-n) is produced is enough to keep the dynamic touch article conducting pair in left side
The stationary contact answered；Now, touch article is moved away from correspondence stationary contact in right side；Dynamic touch article on longitudinal sliding block also fails to conducting, and its is corresponding
Front end stationary contact.
Transverse slider, which moves right, turns on the principle of the corresponding stationary contact in right side, and conducting left side is moved to the left with transverse slider
The principle of corresponding stationary contact is identical；That is, while the correspondence stationary contact of transverse slider conducting right side, the dynamic touch article in its left side is remote
Dynamic touch article on corresponding left side stationary contact, longitudinal sliding block fails to turn on its corresponding front end stationary contact.
Because of transverse slider, the interphase interaction of longitudinal sliding block and action of reset spring, power switching unit has four states：
1) transverse slider turns on left-side switch (other to switch off), 2 at left side) transverse slider turns on right-side switch at right side
(other to switch off), 3) transverse slider centrally and longitudinally sliding block whole process reset when conducting first end switch (other to switch off),
4) transverse slider is when centrally and longitudinally sliding block leaves transverse slider in rear end, and three switches all disconnect；That is, it is any with for the moment
Carve, most only one of which mechanical switch are switched on.
For ease of description, the stable state (transverse slider is locked in left side by longitudinal sliding block) when left-side switch is turned on is referred to as
Left shelves, the stable state (transverse slider is locked in right side by longitudinal sliding block) when right-side switch is turned on is referred to as right shelves, longitudinal sliding block
Stable state (transverse slider is locked in middle position by longitudinal sliding block) during upper mechanical switch conducting is referred to as first shelves, three machineries
Switch the stable state referred to as neutral gear all disconnected.
Transverse slider electromagnet is referred to as DH, and longitudinal sliding block electromagnet is referred to as releasing magnet DJ；
When DH is powered off, transverse slider is reset to middle position；Driving transverse slider moves right when DH leads to forward current；DH
Driving transverse slider is moved to the left during logical reverse current.
When DJ is powered off, longitudinal sliding block forward end resets, and driving longitudinal sliding block is mobile to the back-end when DJ is powered.
Attached following table illustrates the operation principle and its workflow of power switching unit：
It is an advantage of the invention that：
The power switching unit, any synchronization can only at most turn on a phase, fundamentally, prevent handoff procedure
Middle two-phase or three-phase, which are simultaneously turned on, causes the phenomenon of phase fault；
One power switching unit only needs two DMs, and dynamic touch article need to only do simplest rectilinear movement, not have
Rotary motion, fault rate, which is realized, to be minimized；Dynamic touch article does not rub with corresponding stationary contact during being turned on or off, the life-span
Realize and maximize；
When completing switching task, certain grade of state is kept without electric energy or magnetic force；It is mutual using transverse slider and longitudinal sliding block
Chain effect and spring reset effect, zero-power keep certain grade of state of the power switching unit；
When needing multiple power switching units, the transverse slider of multiple power switching units can common drive mechanism, reality
