Abstract
The utility model relates to a double-switch rough and fine-regulating on-load voltage regulator, which has multiple voltage regulating stages, flexible voltage regulation and high operating voltage level and can respectively carry out rough and fine regulation of voltage in any voltage regulating regions within an output voltage varying range. The utility model is provided with a winding composed of an input winding and an output winding, wherein, both ends of a fine regulating coil and a rough regulating coil in the output winding are respectively connected with a fine-regulating on-load switch and a rough-regulating on-load switch, the fine-regulating on-load switch is the head end of a secondary circuit, and the rough-regulating on-load switch is the tail end of the secondary circuit.
Description
The utility model belongs to the thickness accent the automatic coupling voltage regulator of carrying, and particularly a kind of two switch thicknesses are transferred Loading voltage regulator.
Existing thickness is transferred the active-part on-load-tap-changing auto device, is the line end voltage regulating mode, is with a fine tuning loaded switch, selects the number of turn of different tap coils, satisfies the power reguirements of different electric pressures.Its coarse adjustment coil, fine tuning coil form current supply circuit in different serial connection modes through loaded switch, and the height of output voltage is by the number of turn decision of thickness modulation coil serial connection, the i.e. determining positions of switch switching.Pressure regulation progression is the product of coarse adjustment progression and fine tuning progression, and every step voltage adjusting range is the fine tuning voltage across poles.The maximum progression of the Loading voltage regulator of this structure is 48 grades, every step voltage＜500V, and can only adjust step by step with the fine tuning interstage voltage, the coarse adjustment conversion once must wait fine tuning to finish a circulation, a segmentation fine tuning, the thickness that is not real meaning is transferred, and the switch operating voltage can not be higher than 15KV.
The purpose of this utility model is to provide that a kind of pressure regulation progression is many, any pressure regulation interval in the output voltage excursion can carry out respectively adjustment of voltage thickness and pressure regulation flexibly, two switch thicknesses that the operating voltage grade is high transfer Loading voltage regulator.
The utility model is achieved in that it has a winding that is made of input winding and output winding, fine tuning coil and coarse adjustment coil two ends are connected to fine tuning loaded switch and coarse adjustment loaded switch respectively in the output winding, said fine tuning loaded switch is the secondary circuit head end, and said coarse adjustment loaded switch is the secondary circuit end.
The utility model has the advantages that:
1, pressure regulation progression is many, is 17 grades as coarse adjustment, and fine tuning is 8 grades, and then total pressure regulation progression is 8 * 17=136 level;
2, the voltage adjusting range is flexible and changeable, and thick, fine tuning switch moves respectively, can realize coarse adjustment significantly and regional fine tuning, and to satisfy special power reguirements, the switch motion number of times can effectively reduce, and improves pressure regulation efficient;
3, loaded switch is selected flexibly, and operating voltage and interstage voltage scope improve greatly, and operating voltage can reach the 110KV level, and interstage voltage can reach thousands of volts.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical schematic diagram of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in the figure, the utility model has a housing 1, on housing 1, have by input winding and the self coupling winding that constitutes of output winding 4, terminal 3, secondary terminal 5, fine tuning coil 7, coarse adjustment coil 8 two ends are connected to fine tuning loaded switch 2 and coarse adjustment loaded switch 6 respectively in the output winding, wherein fine tuning loaded switch 2 is the secondary circuit head end, and coarse adjustment loaded switch 6 is the secondary circuit end.
