The utility model discloses a counteracting voltage regulator, which comprises a primary coil and a secondary coil; a counteracting coil with opposite winding directions is wound on the secondary coil, and the tail end of the counteracting coil is connected with the tail end of the secondary coil; more than one offset tap is arranged on the offset coil; a secondary coil tap corresponding to the head end of the counteracting coil and the counteracting tap is arranged on the secondary coil; the number of turns from the secondary coil tap to the tail end of the secondary coil is the same as the number of turns from the head end of the corresponding cancellation coil to the tail end of the cancellation coil; and the secondary coil tap is connected with the head end of the corresponding counteracting coil and the counteracting tap through an adjusting switch. The transformer has the advantages that the effect of the magnetic field intensity of the secondary coil is changed by adjusting the size of the magnetic field generated by the offsetting coil and offset with the magnetic field of the secondary coil, so that the voltage of the secondary coil is adjusted, the phenomenon of heat generation of an electric brush does not exist, and the loss of the transformer is reduced.
Description
The technical field is as follows:
the utility model relates to a power equipment especially relates to a formula of offsetting voltage regulator.
Background art:
voltage regulators are widely applied in various fields, but the current used voltage regulators are all contact voltage regulators with brushes sliding on the ground surfaces of coils, and the purpose of regulating voltage is achieved by changing the turn ratio of the coils.
The contact voltage regulator is used for continuously and steplessly regulating AC load voltage and is used as the core part of automatic voltage regulator. Because the electric brush of the contact voltage regulator used at present is pressed on the ground surface of the coil to move, in order to achieve continuous stepless regulation, the electric brush must be simultaneously contacted and pressed with two to three turns, so that the electric brush bears two to three turns of voltage, the larger the power of the voltage regulator is, the larger the turn voltage is, the larger the voltage on the electric brush is acted, so that the electric brush generates more heat, and meanwhile, the voltage regulator forms a short-circuit turn, so that the loss of the transformer is increased.
The utility model has the following contents:
an object of the utility model is to provide a through offset-type voltage regulator of the induction magnetic field who offsets.
The utility model discloses by following technical scheme implement: a buck regulator including a primary coil and a secondary coil; a counteracting coil with opposite winding directions is wound on the secondary coil, and the tail end of the counteracting coil is connected with the tail end of the secondary coil; more than one offset tap is arranged on the offset coil; a secondary coil tap corresponding to the head end of the counteracting coil and the counteracting tap is arranged on the secondary coil; the number of turns from the secondary coil tap to the tail end of the secondary coil is the same as the number of turns from the head end of the corresponding cancellation coil to the tail end of the cancellation coil; and the secondary coil tap is connected with the head end of the corresponding counteracting coil and the counteracting tap through an adjusting switch.
The utility model has the advantages that: compared with the prior art, the magnetic field size which is generated by the adjusting offset coil and offset with the magnetic field of the secondary coil is utilized to change the effect of the magnetic field intensity of the secondary coil, so that the voltage of the secondary coil is adjusted, the phenomenon of heat generation of an electric brush does not exist, and the loss of a transformer is reduced.
Description of the drawings:
fig. 1 is a schematic connection diagram of the present invention.
The specific implementation mode is as follows:
example (b): as shown in fig. 1, the cancellation type voltage regulator includes a primary coil 1 and a secondary coil 2; a counteracting coil 3 with opposite winding directions is wound on the secondary coil 2, and the tail end of the counteracting coil 3 is connected with the tail end of the secondary coil 2; more than one cancellation tap 4 is arranged on the cancellation coil 3; a secondary coil tap 5 corresponding to the head end of the cancellation coil 3 and the cancellation tap 4 is arranged on the secondary coil 2; the number of turns from the secondary coil tap 5 to the tail end of the secondary coil 2 is the same as the number of turns from the head end of the counteracting coil 3 to the tail end of the counteracting coil 3 from the counteracting tap 4; the secondary coil tap 5 is connected with the corresponding head end of the counteracting coil 3 and the counteracting tap 4 through an adjusting switch 6.
The working principle is as follows: according to the electromagnetic induction law and the right-hand rule, when the current directions are the same, the directions of the induced magnetic fields generated in the secondary coil 2 and the counteracting coil 3 with opposite winding directions are opposite, mutual counteracting effect exists, and the magnetic field intensity of the transformer is equal to the vector sum of the magnetic field generated by the secondary coil 2 and the magnetic field generated by the counteracting coil 3; the secondary coil 2 works on line all the time, and the adjustment of the size of the magnetic field generated by the offset coil 3 and offset with the magnetic field of the secondary coil 2 is realized by switching the adjusting switches 6 which are interlocked with each other, so that the effect of changing the magnetic field intensity of the secondary coil 2 is realized, and further the voltage of the secondary coil 2 is adjusted.
