Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is this utility model polarity transformer's series compensation system figure.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, real to this utility model below
The technical scheme executed in example is clearly and completely described, it is clear that described embodiment is that this utility model part is implemented
Example rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making wound
The every other embodiment obtained under the property made work premise, broadly falls into the scope of this utility model protection.
Embodiment 1:
A kind of polarity transformer's series compensation system as shown in Figure 1, including: some transformators, the two of described transformator
Being arranged between ac input end and outfan after secondary coil series connection, the primary winding of described transformator includes positive polarity winding T
+, negative polarity winding T-and the points of common connection g, this positive polarity winding T+ that are arranged between positive and negative electrode winding connect the first switch
K1, negative polarity winding T-connect second switch k2, and described first, second switch (k1, k2) is all connected with ac output end, described
Points of common connection g is connected with neutral conductor N, when voltage added on primary winding and polarity change, can make to be connected on negative
Carry the secondary coil on loop and produce amplitude and the variable compensation voltage of polarity.
Described first, second switch (k1, k2) all switchs k3 by the 3rd and is connected with ac output end, described first, the
Two switches switch for zero cross fired, and this zero cross fired switch uses bidirectional triode thyristor module d, and described points of common connection g is for sliding
Contact, this contact can slide between positive polarity winding T+ and negative polarity winding T-and keep electrical connection, contact can also be fixed
Being arranged between positive polarity winding T+ and negative polarity winding T-, if fixed position, mode is simple, it is not necessary to regulation, not overcompensation
Be limited in scope, concrete service condition needs to select according to particular case.
It should be noted that when the voltage of ac power input end occurs unstable, as being raised and lowered, now by
Control the first switch k1 or break-make of second switch k2, it is achieved the superposition to output voltage compensates.Keep the effect that output is stable
Really.
Below by with 220v voltage example this programme operation principle is described: as it is shown in figure 1, normal civil power requirement
220v, it is assumed that when ac input end voltage is less than 220v, now, in order to ensure still to export stable voltage, conducting the first switch
K1, and sliding contact g is to correct position, electric current flows into from the positive polarity winding T1+ of primary winding, and in contact g flows into
Property line N, it is achieved the voltage compensation to secondary coil, owing to the secondary coil of T1, T2, T3 is all cascaded, therefore compensate folded
Add, it is ensured that ac output end is stable at 220v；When input terminal voltage is more than 220v, same principle, now by conducting the
Two switch k2, and sliding contact g flows into correct position, electric current from the negative polarity winding T1-of primary winding, and through contact g
Flow into neutral conductor N, it is achieved the superposition of voltage compensates, it is ensured that final output voltage is 220V；Electricity when ac power input end
Being pressed in 220v when stablizing, turn on k1, k2, now positive polarity winding T1+ and negative polarity winding T1-is to neutral conductor N current-sharing overcurrent,
Corresponding secondary coil compensates voltage and cancels out each other, therefore, and ac output end output 220v burning voltage.
Additionally, after plus the 3rd switch k3, under ac input end voltage stabilization state, shutoff k3, conducting k1,
K2, now connects between the polarity winding T1+ and negative polarity winding T1-of positive primary winding, becomes ordinary inductor, it is possible to reduce two
The loss of secondary coil, has more preferable effect.
