Abstract
The utility model discloses a contactless self-coupling voltage regulator without air gas partial flow, comprising an iron core. The magnetic loop of the iron core is added with a magnetic partial flow iron core, and a rotatable cylindrical iron core is arranged at one intersection point between the magnetic partial flow iron core and a main magnetic circuit iron core; the both sides of the cylindrical iron core contains two irregular magnet conduction members which divide the circumference of the rotatable cylindrical iron core into four areas; the magnetic force line proportion that passes through secondary coils and the magnetic partial flow iron core can be changed by rotating the rotatable cylindrical iron core; when the rotation angle of the rotatable cylindrical iron core exceeds a certain angle, the magnetic force line of a primary side passes through mostly the magnetic partial flow iron core or the secondary coils, which regulates the voltage, and the change of the magnetic resistance of the magnetic loop is few when regulating the voltage.
Description
The utility model is the contactless voltage-regulating device that is used to regulate the no air gap shunting of alternating voltage.
It is traditional that automatic coupling voltage regulator existing shortcoming in contact is arranged is well-known.Soviet Union's " description of the invention 860152 " number has proposed the non-contact type automatic coupling voltage regulator, solves these problems.But this voltage regulator is by changing the shunt magnetic air-gap and changing the method work of passing secondary coil magnetic line of force magnetic resistance.Can make the increasing of voltage regulator primary current cause electric energy loss owing to increase magnetic resistance, therefore be necessary to change this voltage regulating mode.
The purpose of this utility model will guarantee to solve magnetic resistance exactly and add the problem that ambassador's primary current rises on the basis of existing contactless automatic coupling voltage regulator advantage.
As shown in the figure.On day font voltage regulator iron core 1, be wound with former limit winding W
1With a pair limit winding W
2, one in the middle of day font is shunt magnetic stem 6.On the intersection point that shunt magnetic stem 6 and day font one erect, rotating unshakable in one's determination 2, unshakable in one's determination 2 top and the bottom that this is perpendicular are housed link up with shunting stems 6.Bad magnetic conduction thing 3 and 4 are housed on rotating unshakable in one's determination 2, are divided into four zones by 3 and 4 circumference with iron core 2.Unshakable in one's determination 2 is very little with the fit clearance of day shaped iron core, but can rotate.Rotate iron core 2, just change the allocation proportion of magnetic conduction sectional area unshakable in one's determination, but do not change the magnetic conduction sectional area on the magnetic conduction road.When unshakable in one's determination 2 when the direction of B is rotated, the magnetic line of force on former limit just increases through the part of magnetic shunt, and that passes secondary coil just reduces W
2On coupled voltages just reduced.So just changed output voltage.When 2 directions along B unshakable in one's determination turned over 90 °, the magnetic line of force that former limit produces was almost all by shunt magnetic stem 6.There is not the problem of regulating air gap in whole pressure regulation process, because magnetic property unshakable in one's determination is fine, magnetic resistance changes less and regulates air gap by comparison, almost can ignore.
Automatic coupling voltage regulator is widely used in various electrical testing laboratories and other needs the occasion of regulation voltage or power. This pressure regulator also can use as general transformer.
Claims (1)
- A kind of contactless automatic coupling voltage regulator is characterized in that having increased the unshakable in one's determination and rotating iron core of a shunt magnetic on the magnetic loop of iron core.Fit clearance between rotatable iron core and main magnetic circuit iron core and the shunt magnetic iron core is very little, but can rotate.Include bad magnetic conduction substance in rotatable unshakable in one's determination both sides, be divided into four zones around unshakable in one's determination thereby will turn, the surface in two zones be unshakable in one's determination can magnetic conduction, the surface in two zones is bad magnetic conduction thing.
