Abstract
The utility model discloses a three-phase stepless voltage regulator which is a novel voltage regulating device with a large capacity, composed of a main transformer with two windings and a contact type autotransformer. The three-phase stepless voltage regulator can make the output voltage of the main transformer be smoothly changed in a limited range through regulating the size and phase position of the output voltage of the autotransformer to realize the stepless voltage regulation. The utility model has high efficiency and low energy consumption, can be widely used in various occasions needing the large-capacity voltage regulation and also be used as a voltage-stabilizing and a motor starting equipment.
Description
The utility model relates to a kind of big capacity stepless voltage regulator of adjusting voltage.
In industrial production and scientific research, the occasion at the big capacity adjustment of needs voltage generally adopts induction type or shifting coil voltage regulator.The three-phase moving coil voltage regulator is made up of three identical single-phase moving coil voltage regulators, each single-phase moving coil voltage regulator all is made up of shell type iron core, alignment circle and short-circuited coil, be enclosed within on the core limb after two alignment circle differential concatenations, short-circuited coil then is enclosed within the outside of alignment circle.When the core limb height moves short-circuited coil, can change the magnetic flux distribution in the iron core, reach the purpose of even adjustment voltage.Because two alignment circle differential concatenations, the flow direction that produces each other are opposite, and short circuit current and most main flux in the short-circuited coil all pass air-gap, so the no-load loss of this voltage regulator and no-load current are much larger than general transformer; Big owing to core volume again, bulky, the complex structure of the three-phase moving coil voltage regulator that combines.Therefore, this three-phase moving coil voltage regulator is not suitable for big capacity and adjusts voltage usefulness.
The purpose of this utility model is improved the structure of three-phase moving coil voltage regulator of the prior art, significantly to reduce the volume of voltage regulator, raises the efficiency, reduces the wastage.
To achieve these goals, the utility model adopts three-phase two winding main transformers and a three-phase contact autotransformer to form a three-phase stepless voltage regulator through suitable connection, and employing changes the size of contact autotransformer output voltage and the method for phase place, the output voltage of main transformer is changed in certain scope smoothly, realize stepless voltage regulation.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model three-phase stepless voltage regulator.
The three-phase stepless voltage regulator is made up of three identical single-phase stepless voltage regulators of structure, and Fig. 1 is the structural representation of single-phase stepless voltage regulator.
Each single-phase stepless voltage regulator is formed by one two winding main transformer 1 and a contact autotransformer 2.One end of one end of a winding 3 of main transformer 1 and the self coupling coil 5 of autotransformer 2 joins and as the input of whole voltage regulator, the other end of a winding 3 of main transformer 1 is as the output of whole voltage regulator.The two ends of the secondary winding 4 of main transformer 1 electrically contact with the both sides of self coupling coil 5 respectively by two armature contacts 6, armature contact 6 can for example can be made a pair of carbon brush with two armature contacts and utilize 7 drivings of a motor to make it along self coupling coil slide in opposition along self coupling coil 5 move toward one another.For the voltage regulator of forming as stated above, as long as change the contact position of armature contact 6 and self coupling coil 5 size and the phase place (with respect to main transformer secondary winding 4) of the output voltage of autotransformer 2 are changed, thereby the output voltage of a winding of main transformer 1 is changed within the specific limits smoothly, realize stepless voltage regulation.
The utility model is compared with the three-phase moving coil voltage regulator with capacity, has the advantage that manufacturing process is simple, machine volume is little, can save silicon steel sheet 50%, saves copper material 40%, and copper loss and iron loss significantly reduce, and efficient can be brought up to more than 95%. Therefore, the utility model can as the big capacity stepless voltage regulation of bringing onto load usefulness in industrial production and scientific research, also can be used as voltage stabilizing and electric motor starting equipment.
