Abstract
The utility model discloses two voltage regulators, which aims to decrease the style capacity of the voltage regulator when the output power is a fixed value to achieve the purposes of saving materials and reducing electric energy loss. One voltage regulator is a voltage-rising and voltage-reduction type voltage regulator, and the special-purpose winding segment which is used in the duration of voltage boosting is used as primary and secondary stage common windings to be connected to circuits; the other voltage regulator is voltage reduction voltage regulator which provides power for the loads which can be divided into two parts, the winding of the reduction voltage regulator is provided with taps or end heads which are respectively connected with each load, and two implementation examples are provided.
Description
The utility model relates to two kinds of improved variacs (being called for short " voltage regulator ") that tap is arranged.Purpose is when power output is definite value, reduces the pattern capacity of voltage regulator, to save material and to reduce electric energy loss.
A kind of ascending, descending voltage regulator, prior art such as Fig. 1, winding sequentially has top B on (1)
2, tap terminals A, tap terminals B
1And tail end X.The common port that connects power supply and load simultaneously is X.Power supply meets end A.Meet end B during load step-down
1, meet end B when boosting
2Improved voltage regulator is as step-up ratio K
1Less than 2 o'clock, the winding segments of special use when it boosts, as primary and secondary common winding and place in circuit, thereby its conductor cross-section determines (as Fig. 1 middle-end B by load current during work
2, one section winding between A) be little.As the voltage regulator of Fig. 2, meet the top A of power supply when on the winding (2) step-down being arranged
1, the common port X during step-down
1And at end A
1With end X
1Between (not shown) step-down the time connect the tap terminals of load, it is characterized in that end A at winding (2)
1, X
1Between meet one group of tap C of power supply when boosting in addition
1To C
N(also can have only a tap C
1), and at the terminal Y of winding
1With end X
1Between one group of common port Y that uses when boosting on the special-purpose winding segments when boosting
1To Y
N(also can have only an end Y
1), the end that connects load when boosting then is top A
1Obviously, this moment secondary winding the section of boosting part, the end A among Fig. 2 for example
1, C
1Between one section series connection winding segments when then using (or having comprised) step-down.When step-down step-down ratio the most for a long time is K, and K>0.5 o'clock, exit C
1(or connect when boosting in one group of end of power supply apart from end X
1Nearest person) at end A
1, X
1Between the position, if need to connect the most for a long time the end (not shown) and end X of load in step-down
1Between, then should check, the product form capacity can less than prior art products.
Example is that the ascending, descending voltage regulator use in the Elema heating in the corrugated paper machine, and the end that connects power supply when some boost connects the end merging of load during with step-down, as the end C on Fig. 2 winding (2)
1To C
N, the end in another section is Y
1To Y
N, at this N=5.Connection and parameter see Table 1.
