Abstract
The invention discloses a single-phase double-on-load voltage-regulating transformer capable of outputting different single-phase voltages. The voltage-regulating transformer comprises a box body, wherein both sides of the upper part of the box body are respectively provided with a cavity, and the cavities are respectively and internally provided with an on-load switch; the box body is internally provided with four iron-core posts mutually matched with the two on-load switches; and coils are arranged on two of the four iron-core posts. The single-phase on-load voltage-regulating transformer can realize that one transformer outputs different single-phase voltages.
Description
Technical field
The present invention relates to a kind of single-phase on-load tap-changing transformer, relate in particular to a kind of single-phase double-on-load voltage-regulating transformer.
Background technology
As shown in Figure 1, traditional single-phase on-load tap-changing transformer, all be in the top one side cavity 11 of the casing 1 of transformer, a loaded switch 2 to be set, in casing 1, be provided with two core limbs that cooperatively interact with loaded switch, core limb is provided with coil, regulates loaded switch 2, and the core limb coil turn will change, the flux change unanimity of two core limbs, the single-phase voltage that transformer is exported also can change simultaneously.The shortcoming of this single-phase on-load tap-changing transformer is: because only be provided with a loaded switch 2 in the top one side cavity of its casing 1, the single-phase voltage that two coils of transformer are exported can only be the same, can not realize two different single-phase voltages of a transformer output.
Summary of the invention
Technical problem to be solved by this invention is: a kind of single-phase on-load tap-changing transformer that can export different single-phase voltages is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: single-phase on-load tap-changing transformer, comprise: casing, the both sides, top of described casing are respectively arranged with cavity, in cavity, be respectively arranged with two loaded switchs, be provided with four core limbs that cooperatively interact with two loaded switchs in casing, two core limbs are provided with coil therein.
Advantage of the present invention is: the single-phase on-load tap-changing transformer of this structure, can realize that two coils of a transformer export different single-phase voltages.
Description of drawings
Fig. 1 is the structural representation of single-phase on-load tap-changing transformer in the background technology.
Fig. 2 is the structural representation of the single-phase on-load tap-changing transformer of the present invention.
Among the figure: 1, casing, 11, cavity, 2, loaded switch, 3, casing, 31, cavity, 32, cavity, 41, loaded switch, 42, loaded switch.
Embodiment
Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 2, single-phase on-load tap-changing transformer, comprise: casing 3, the both sides, top of described casing 3 are respectively arranged with cavity 31 and cavity 32, in cavity 31, be provided with a loaded switch 41, be provided with a loaded switch 42 in cavity 32, be provided with four core limbs that cooperatively interact with loaded switch 41 and loaded switch 42 in casing 3, two core limbs are provided with coil therein.
The single-phase on-load tap-changing transformer of this structure when work, is regulated loaded switch 41, and the core limb coil turn that cooperatively interacts with it will change, thereby the magnetic flux of core limb is changed, and transformer can be exported a kind of single-phase voltage with regard to this coil.Regulate loaded switch 42, the core limb coil turn that cooperatively interacts with it will change, thereby the magnetic flux of core limb is changed, and this coil of transformer will be exported another kind of single-phase voltage.Thereby realize that a transformer exports the purpose of different single-phase voltages.
Claims (1)
