Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of low pressure voltage-stabilizing voltage regulator of the present utility model.
Embodiment
As shown in Figure 1, the low pressure voltage-stabilizing voltage regulator of the present embodiment, it comprises an autotransformer, and described autotransformer input 1 is placed in winding, and its output 2 is placed in winding terminal; It also arranges 3 taps in winding, comprises two input taps and an output tap, and described output tap is placed between two input taps; Two inputs tap is arranged on the line respectively K switch 1, K2; Export a capacitor 3 that tap circuit connects, this capacitor is in parallel with series coil.
This low pressure voltage-stabilizing voltage regulator, its series transformer accesses series capacitor 3.By access series capacitor 3, reduce line impedance and reduce voltage fluctuation.Transformer is autotransformer, and the automatic Regulation when load peak voltage drop is excessive, realizes voltage stabilizing.
The concrete condition of the present embodiment low pressure voltage-stabilizing voltage regulator is as shown in Figure 1:

The low pressure voltage-stabilizing voltage regulator detailed technology scheme of the present embodiment is:
If 1.. when output 1 voltage is between 375V ~ 400V, be failure to actuate, maintain former tap.
If 2.. during output voltage >400V, lower one grade of step-down.Such as: the former k1 that is tapped at closes k2 timesharing, convert k2 conjunction k1 to and divide, the former k2 that is tapped at closes k1 timesharing, converts k1, k2 to and all divides.
3.. during output voltage <375V, raise one grade of boosting.Such as: be formerly tapped at that k2 closes, k1 timesharing, convert that k1 closes, k2 divides to, be formerly tapped at k1, k2 all timesharing, convert k2 to and close k1 and divide.
4.. when being in the most high-grade (k1 closes, k2 open), output voltage is <375V still, is failure to actuate, and maintains former tap.
5.. when being in deep low gear (k1, k2 open entirely), output voltage is >400V still, is failure to actuate, and maintains former tap.
6. lower voltage limit 375v is adjustable definite value, adjustable between 361 ~ 375.
