Description
Technical field
This utility model relates to electric power project engineering field, particularly relates to a kind of automatic powerstat.
Background technology
Transformator is an active electrical equipment, owing to line voltage electricity capacity changes at any time, its distribution transformer
Once survey voltage pulsation very big, cause distribution transformer secondary side spread of voltage, thus affect the power quality of user.
And some special dimension, such as precise electronic instrument be necessary to ensure that power supply excursion in less precision, and
Rely solely on the voltage stabilizing voltage stabilizing of instrument internal it cannot be guaranteed that the excursion of input voltage, therefore also need when precise electronic instrument uses
To ensure by stable voltage.
Common transformer is in the case of output is constant, it is possible to ensureing required precision, once output changes
Scope is relatively big, and the secondary voltage of common transformer has no idea to be automatically adjusted, it is impossible to ensure that instrument can work normally, instrument
Precision can decline, affect work quality.

Joint side, core front connects spring, and the opposite side of spring connects permanent magnetic iron block, connects mobile bar after permanent magnetic iron block, and primary coil sets
Being equipped with groove, mobile bar is connected with each other with groove.This utility model moves pole length and can according to circumstances adjust, and primary coil is shielded
The maximum quantity covered is accurately controlled, and then the output voltage of adjustment transformator that can be relatively reasonable so that it is output voltage is steady
Fixed.
The technical solution of the utility model is: a kind of automatic powerstat, including iron core, mobile bar, permanent magnetic iron block, bullet
Spring, primary coil, regulation core, secondary coil, groove, iron core both sides are respectively provided with primary coil and secondary coil, wherein primary
Regulation core is also comprised inside coil side, it is characterised in that: described side, regulation core front connects spring, the opposite side of spring

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
Fig. 1 be this utility model automatic powerstat single-phase time structural representation, wherein U be primary voltage input, u
Export for voltage；Fig. 2 is the structural representation of automatic powerstat three phase time, and wherein A, B, C are three phase mains input, a,
B, c are respectively output 220V live wire, and N is zero line.
As shown in Figure 1 and Figure 2, this utility model include iron core 1, mobile bar 2, permanent magnetic iron block 3, spring 4, primary coil 5,
Regulation core 6, secondary coil 7, iron core 1 both sides are respectively provided with primary coil 5 and secondary coil 7, wherein inside primary coil 5 side
Also comprising regulation core 6, regulation side, core 6 front connects spring 4, and the opposite side of spring 4 connects permanent magnetic iron block 3, after permanent magnetic iron block 3
Connecting mobile bar 2, mobile bar 2 is connected with each other with the groove in primary coil 5.In this utility model, mobile bar 2 arranges longer,
So can contact with each other with multiple primary coils 5.In this utility model, the magnetic pole of permanent magnetic iron block 3 with to regulation core 6 lead to
Magnetic pole homopolarity during electricity is put, and when voltage increases, regulation core 6 magnetic flux increases, and promotes and moves outside permanent magnetic iron block 3, drives mobile
Bar 2 is outer to be moved.This utility model also includes housing 8, and the device of adjustable transformer is arranged in housing 8.
As shown in Figure 3 and Figure 4, the primary coil 5 that this utility model contacts with mobile bar 2 is provided with groove 9, and groove 9 is
It is well that the big collar extension of internal orifice is little, as it is shown on figure 3, after so connecting, it can be ensured that mobile bar 2 slides in multiple primary coils 5, and not
Can offset, and increase the contact area of mobile bar 2 and primary coil 5 simultaneously, reduce resistance.As shown in Figure 4, this practicality is new
The mobile bar 2 of type is middle little, and the longer pole that two ends are big, so moving bar 2 can be stuck in groove 9 just, and moves
Dynamic moving forward and backward does not comes off.
Work process of the present utility model is: the magnetic pole of permanent magnetic iron block 3 with to regulation core 6 be energized time magnetic pole homopolarity
Put, when input voltage reduces, regulation core 6 magnetic flux reduce, permanent magnetic iron block 3 under the pulling force of spring 4, slid inward, by
Being longer conductor in mobile bar 2, its part primary coil 5 two ends all contact mobile bar 2, then be equivalent to the coil quilt being touched
Shielding, so the coil number in primary coil 5 reduces, then can be correspondingly improved the voltage of output part, make output voltage maintain
Constant；Input voltage raise time, regulation core 6 magnetic flux increase, permanent magnetic iron block 3, under the promotion of spring 4, slides in and out, then at the beginning of
The number of turns that level coil 5 two ends all contact mobile bar 2 is less, so the coil number in primary coil 5 increases, then can reduce accordingly
The voltage of output part, makes output voltage remain unchanged.
This utility model voltage input point immobilizes, even if stable-pressure device breaks down, is just nor affecting on transformator
Often work；Secondly mobile bar 2 length of the present utility model can according to circumstances adjust, and the maximum quantity that primary coil 5 is shielded can
Accurately control.
