Abstract

The utility model discloses a self-coupling transformer with sectional output, belonging to the technical field of electro-technology. The self-coupling transformer with sectional output refers to the constitutive principle of multilayer winding automatic coupling voltage regulator, the windings to which the non-used sections of the full output sections are corresponding are used as inner layer windings, the windings to which the other required-used sections are corresponding are used as outer layer windings, and an electric brush is only in contact with the outer layer windings to form the needed sectional output. If the inner layer windings and the outer layer windings are made be independent, an additional rectifying element is added, and thus an isolated form direct current adjustable power supply can be obtained. The utility model raises the availability of the iron core and the volume weight ratio, and the utility model is suitable for the regulation voltage of electrical equipment, etc.

Description

Self-coupling transformer with sectional output

Section output type automatic coupling voltage regulator belongs to electrical technology field.

General automatic coupling voltage regulator owing to different occasion requirements, all uses on the gamut of the non-voltage regulator of being everlasting of And (for example from 0 volt to the 250 volts) scope in actual use.As in some equipment, doing the supply voltage adjustment when it, it only is operated in 165 volts to 250 volts the scope, and in electrophoresis is filmed, only need to be operated on 50 volts to the 150 volts sections, required automatic coupling voltage regulator only is operated on 100 volts to the 200 volts sections and works in some electronic equipment for another example.Therefore, common employed voltage regulator exists waste to a great extent at present, and redundant output section has promptly dwindled effective utilization unshakable in one's determination, and it is big to make it volume, and quality is heavy, is unfavorable for improving volume to weight ratio, is unfavorable for that again the isolation of voltage regulator is used.

The utility model be intended to propose a kind of can the requirement according to the difference that reality is used and can be in the gamut scope automatic coupling voltage regulator of section output arbitrarily.

The utility model utilizes the automatic coupling voltage regulator structural principle of No. 86100524 multilayer windings that patent application proposed of the inventor, with the pairing coil windings of the section that need not use in the automatic coupling voltage regulator gamut as internal layer, and with the essential pairing coil windings of using of section in the range as skin, be around on the internal layer, make it and to contact with brush.Under special circumstances, can be on which floor of the inside with the input of winding, and make them separate as output coil And skin, and just can get an isolated voltage regulating device, if add by rectifier cell, then can get adjustable power of direct current at output.

The sectional arrangement drawing of of the present utility model a kind of section output type automatic coupling voltage regulator that Figure of description 1 provides.It is expressed as follows: (1) is ring-shaped core, and (2) are winding, and (3) are the insulation cushion domain, and (4) are brush, and (5) are tight loop, and (6) are base, and (7) are handle, and (8) are the output indication.The convex edge part of the insulation cushion domain (3) of this device is placed in the outer last transverse plane of internal layer winding of ring-shaped core (1).

The sectional arrangement drawing of the of the present utility model another kind of section output type automatic coupling voltage regulator that Figure of description 2 provides.It is expressed as follows: (1) is ring-shaped core, and (2) are winding, and (3) are the insulation cushion domain, and (4) are brush, and (5) are tight loop, and (6) are base, and (7) are handle, and (8) are the output indication.The convex edge part of the insulation cushion domain of this device is placed in the outer side of internal layer winding of ring-shaped core (1).

Here provide an embodiment of the present utility model:

A kind of capacity is that 1KVA, input voltage are that 220 volts, output voltage are that 160 volts to 245 volts, output current are 4 amperes section output type automatic coupling voltage regulator, mainly is made up of ring-shaped core (1), winding (2), the insulation cushion domain (3), brush (4).Ring-shaped core (1) volume that is wound into by the thick silicon steel sheet of 0.3mm is: external diameter 90mm, internal diameter 44mm, high 45mm, after insulation is handled, directly be that the 0.67mm enamelled wire is around 295 circles with line, remake insulation processing, become the internal layer winding with 0.67mm line footpath enamelled wire around 147 circles its outside continuation.Internal layer winding outside adds the insulation cushion domain (3) in the top after insulation is handled, make the convex edge part of the insulation cushion domain (3) outside, and reconfiguration 1.0mm line footpath enamelled wire becomes outer winding around 250 circles then.Brush (4) is omnidistance the slip on the corresponding outer winding in the part position, convex edge of the insulation cushion domain (3).The convex edge part of the insulation cushion domain (3) can be placed in the outer upper end or the lower end of internal layer winding of ring-shaped core (1), also can be positioned over ring-shaped core (1) internal layer winding outer side middle-end or other corresponding optional positions, side as required.It is corresponding that brush (4) is positioned at the part position, convex edge of the insulation cushion domain (3) all the time.Each layer winding can be formed by an enamelled wire coiling, also can be formed by many enamelled wire coilings.By rotating shaft the ring-shaped core (1) that is wound with winding (2) and tight loop (5), base (6) are linked, handle (7) and output indication (8) are installed in the top of rotating shaft respectively, when using many enamelled wire coilings, can be with the internal layer of winding (2) as input, and can make inside and outside layer winding separate as the output And of coil outer winding, just can obtain an isolated form voltage regulator this moment, when at output adjunction rectifier cell, then this voltage regulator just can become adjustable power of direct current.

This practicality utilizes the principle of the self-coupling device of No. 86100524 described multilayer windings of patent application of the inventor, need not use the corresponding winding of output section as the internal layer winding the full range of pressure regulator, and the corresponding winding of the output section that will use is as corresponding with brush, can fully improve utilization rate unshakable in one's determination, carry high density ratio, dwindle and alleviated the volume and weight of pressure regulator. This device is applicable to that instrument and meter and electric equipment be used as regulation voltage
