There are primary coil 14, secondary coil 13.
Working principle of the present invention:
Magnetic fluid is a kind of magnetic conduction liquid, and the magnetic permeability ratio of left magnetic fluid 2 and right magnetic fluid 7 is n:1 (n > 1), therefore identical
Under length, same cross-sectional area, the magnetic resistance of right magnetic fluid 7 is n times of the magnetic resistance of left magnetic fluid 2.
In transformer not pressure regulation, left chamber body knob 19 and right chamber body knob 23 are rotated clockwise, makes left inside cavity stomata
21 are not connected to left chamber body knob gas circuit 20, and right inner chamber body stomata 22 is not connected to right chamber body knob gas circuit 24.
In transformer regulating, left chamber body knob 19 and right chamber body knob 23 are rotated counterclockwise, makes left inside cavity stomata 21
It is connected with left chamber body knob gas circuit 20, right inner chamber body stomata 22 is connected with right chamber body knob gas circuit 24.
When primary coil 14 connects AC power source, the alternating current flowed through on primary coil 14 just generates an alternation
Magnetic flux.A part of magnetic flux of this alternating flux passes through secondary coil 13, and secondary coil 13 generates output induced voltage；Another part
Magnetic flux passes through the magnetic circuit that is made of magnetic fluid 2 left in piston guide hole 3 and right magnetic fluid 7.
When rotating clockwise adjusting pressuring knob 8, piston push rod 4 pushes piston 17 in piston guide hole 3 along piston push rod 4
Advance to the left, left magnetic fluid 2 flows into left inside cavity 1 from 3 left end of piston guide hole, and the length of left magnetic fluid 2 is reduced.Meanwhile it is right
Magnetic fluid 7 flows into 3 right end of piston guide hole from right inner chamber body 5, and the length of right magnetic fluid 7 increases, makes by left magnetic fluid 2 and right magnetic
The magnetic resistance for the magnetic circuit that fluid 7 is constituted increases, to reduce the magnetic flux for the magnetic circuit being made of left magnetic fluid 2 and right magnetic fluid 7, increases
The magnetic flux across secondary coil 13 is added, the induced voltage that secondary coil 13 exports increases.When piston 17 is displaced to piston guide
When 3 left end of hole, left magnetic fluid 2 all flows into left inside cavity 1, and magnetic resistance is maximum at this time, by magnetic flux it is minimum, cause by secondary
The magnetic flux of grade coil 13 is maximum, and the output voltage of secondary coil 13 is maximum.
When rotation adjusting pressuring knob 8 counterclockwise, piston push rod 4 pushes piston 17 in piston guide hole 3 along piston push rod 4
It retreats to the right, left magnetic fluid 2 flows into 3 left end of piston guide hole from left inside cavity 1, and the length of left magnetic fluid 2 increases.Meanwhile it is right
Magnetic fluid 7 flows into right inner chamber body 5 from 3 right end of piston guide hole, and the length of right magnetic fluid 7 reduces, makes by left magnetic fluid 2 and right magnetic
The magnetic resistance for the magnetic circuit that fluid 7 is constituted is reduced, to increase the magnetic flux for the magnetic circuit being made of left magnetic fluid 2 and right magnetic fluid 7, is subtracted
The magnetic flux across secondary coil 13 is lacked, the induced voltage that secondary coil 13 exports is reduced.When piston 17 is displaced to piston guide
When 3 right end of hole, right magnetic fluid 7 all flows into right inner chamber body 5, and magnetic resistance is minimum at this time, by magnetic flux it is maximum, cause by secondary
The magnetic flux of grade coil 13 is minimum, and the output voltage of secondary coil 13 is minimum.
In this way, the magnetic resistance for the magnetic circuit being made of left magnetic fluid 2 and right magnetic fluid 7 is changed by rotation adjusting pressuring knob 8, from
And the magnetic flux size by secondary coil 13 is changed, change the output induced voltage of secondary coil 13.Due to being continuously to change
The magnetic flux size of secondary coil 13 is crossed in accommodation, realizes the stepless voltage regulation of transformer.
