Description
Technical field
The present invention relates to electrical equipment, especially, is related to a kind of transformer.
Background technology
Transformer is a kind of conventional electrical equipment, in order to improve the versatility of transformer, at present with more transformation
Device can adjust its output voltage；And for this kind of powerstat, conventional structure be design on the secondary winding it is multiple
Tap, make an output end of secondary coil by Gear-shift switch, may be selected in electrical contact from different taps, exported so as to realize
The regulation of voltage.However, this kind of transformer is only capable of exporting a few voltage equal with the number of taps；And due to taking out
Coordinated between head and output end by movable gearshift mechanism, be easier to release damage during use.
The content of the invention
In view of the above-mentioned problems, not only may be used it is an object of the invention to provide one kind without tap continuous transformer, the transformer
To continuously adjust output voltage, and non-activity structure, it is hardly damaged.
The technical solution adopted for the present invention to solve the technical problems is：This includes iron core, institute without tap continuous transformer
State iron core and be coated with insulating barrier；Rotating around being equipped with primary coil, secondary coil on two side frames of the iron core；Described time
Each circle conductive line surfaces of level coil are electrically exposed, and frame of each circle wire along iron core is coiled into solenoid shape, and between each circle wire
Clearance for insulation is left, and the insertion of each circle wire is made in the spiral form isolation recesses on iron core frame；The secondary coil
A cylindricality hydraulic cylinder for surrounding the secondary coil is equipped with the frame at place, is nested with the hydraulic cylinder provided with one in iron
Sliding plug on core frame, the side of the sliding plug are full of conduction liquid, and the conduction liquid connects a conduction liquid adjuster by connecting leg,
The conduction liquid adjuster can adjust the liquid column length of the conduction liquid in the hydraulic cylinder.
Preferably, the conduction liquid is mercury or sodium chloride solution；The conduction liquid adjuster, which includes storage, conduction liquid
Regulation cylinder, the regulation cylinder changes the conduction liquid reserves in regulation cylinder, so as to adjust by adjusting the position of regulating piston
State the liquid column length of the conduction liquid in hydraulic cylinder.Further, the regulating piston connects a piston rod, on the piston rod
The voltage calibration line being equally spaced is carved with, by piston rod described in push-and-pull, realizes the fluid column to the conduction liquid in the hydraulic cylinder
The regulation of length, and as the output voltage corresponding to the voltage calibration line reads current liquid column length.
Preferably, the hydraulic cylinder is made up of non-conductor, and the insulation midfeather point inside it by axially extending
It is divided into around the uniform branch of more than 2 of axis；The sliding plug is also divided into the branch of more than 2 by the midfeather；So as to
The alternating magnetic field in iron core frame can not be formed the vortex flow around hydraulic cylinder axis in conduction liquid.
The beneficial effects of the present invention are：When this works without tap continuous transformer, it need to only adjust in the hydraulic cylinder
Conduction liquid liquid column length, you can each circle wire for making to be surrounded by conduction liquid is electrically connected with into an equipotentiality body, and is no longer joined
Contributed with transformation, only by the ratio between the remaining wire number of turn in the secondary coil and the number of turn of the primary coil, form output
Input voltage ratio；Due to the liquid column length by continuously adjusting conduction liquid, you can continuously adjust remaining in the secondary coil
The wire number of turn, it is achieved that output voltage continuously adjusts；Also, because secondary coil is a fixed entirety, do not deposit
Releasing or the failure such as loose contact.
Brief description of the drawings
Fig. 1 is this schematic diagram without tap continuous transformer one embodiment.
Fig. 2 is this without in tap continuous transformer, the cross-sectional view of hydraulic cylinder.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
In the embodiment shown in fig. 1, this includes iron core 1 without tap continuous transformer, and the iron core 1 is coated with insulation
Layer；Rotating around being equipped with primary coil 21, secondary coil 22 on two side frames of the iron core 1；Each circle of the secondary coil 22
Conductive line surfaces are electrically exposed, and frame of each circle wire along iron core 1 is coiled into solenoid shape, and are left between each circle wire between insulation
Gap, and the insertion of each circle wire is made in the spiral form isolation recesses on iron core frame；Side where the secondary coil 22
A cylindricality hydraulic cylinder 3 for surrounding the secondary coil 22 is equipped with frame, is nested with the hydraulic cylinder 3 provided with one on iron core side
Sliding plug 4 on frame, the side of the sliding plug 4 are full of conduction liquid 5, and the conduction liquid 5 connects a conduction liquid adjuster by connecting leg 6
7, the conduction liquid adjuster 7 can adjust the liquid column length of the conduction liquid 5 in the hydraulic cylinder 3；Without conduction liquid 5 in hydraulic cylinder 3
One end be then provided with passage 30.
In the present embodiment, the conduction liquid is mercury or sodium chloride solution；The conduction liquid adjuster 7 as shown in figure 1,
There is the regulation cylinder 70 of conduction liquid including storage, the regulation cylinder 70 changes in regulation cylinder 70 by adjusting the position of regulating piston 71
Conduction liquid reserves, so as to adjust the liquid column length of the conduction liquid in the hydraulic cylinder 3.Specifically, the regulating piston 71 connects
A piston rod 72 is connect, by piston rod 72 described in push-and-pull, is realized to the liquid column length of the conduction liquid 5 in the hydraulic cylinder 3
Regulation；The voltage calibration line being equally spaced also is carved with the piston rod 72, the end face to adjust cylinder 70 is used as benchmark, you can by
The voltage calibration line reads the output voltage corresponding to current liquid column length；That is, the end face institute face for adjusting cylinder 70 is currently electric
Pressure graduation mark is current output voltage.
During above-mentioned no tap continuous transformer work, the fluid column length of the conduction liquid 5 in the hydraulic cylinder 3 need to be only adjusted
Degree, you can each circle wire for making to be surrounded by conduction liquid 5 is electrically connected with into an equipotentiality body, and is no longer participate in transformation contribution, only by
The ratio between the remaining wire number of turn and the number of turn of the primary coil 21 in the secondary coil 22, form output input voltage ratios；
Due to the liquid column length by continuously adjusting conduction liquid 5, you can the remaining wire number of turn in the secondary coil 22 is continuously adjusted,
It is achieved that output voltage continuously adjusts；Also, because secondary coil 22 is a fixed entirety, in the absence of releasing or
The failures such as loose contact.
In addition, for the hydraulic cylinder 3, the cross section of one embodiment as shown in Fig. 2 the hydraulic cylinder 3 by non-conductor
Form, and be separated into inside it by the insulation midfeather 31 axially extended around the uniform multiple branches of axis；The sliding plug 4
Also multiple branches are divided into by the midfeather 31；So that the alternating magnetic field in the frame of iron core 1 can not be formed in conduction liquid
Around the vortex flow of hydraulic cylinder axis.If it is pointed out that without the midfeather 31, the conduction liquid 5 is actually also only
Extract a circle alternating magnetic field, its caused vortex flow be actually also it is more faint, therefore midfeather 31 nor have to
Can not.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution, it should be included in the scope of the protection.
