Abstract
The invention discloses an improved autotransformer. The improved autotransformer comprises a superposed iron core (1) which is installed between the upper surface and the lower surface of an iron yoke body (8) in a clamped mode, an upper clamping piece (3) is installed on the upper surface of the iron yoke body (8), a lower clamping piece (2) is installed on the lower surface of the iron yoke body (8), a shielding cover (4) is installed on the iron yoke body (8), and the shielding cover (4) is arranged above the superposed iron core (1) in a covering mode. The improved autotransformer has better safety performance, the service life can also be prolonged, and meanwhile production cost of a power distribution cabinet further can be saved.
Description
Technical field:
The present invention relates to the transformer technology field, more specifically to a kind of improved autotransformer.
Background technology:
Transformer generally can be placed in the power distribution cabinet and use, when placing, the cabinet wall of transformer and power distribution cabinet need to be kept corresponding safe distance, yet because the iron core of present transformer partly is directly exposed in the inner space of power distribution cabinet, in order to keep enough safe distances, need to be with the more increasing of the size design of power distribution cabinet, can cause so a large amount of space of a large amount of wastes, so that the production cost of power distribution cabinet increases, and in the narrower and small occasion in some space, can not place under the situation of enough large power distribution cabinet, such transformer can have very large potential safety hazard.
Summary of the invention:
Purpose of the present invention just is to provide a kind of improved autotransformer, and it has better security performance, and can increase the service life, and can also save the production cost of power distribution cabinet simultaneously.
For achieving the above object, a kind of improved autotransformer of the present invention comprises the stack iron core, the clamping of described stack iron core is installed between the iron yoke body, the upper surface of iron yoke body is equipped with upper clamping piece, the lower surface of described iron yoke body is equipped with lower clamping piece, on the described iron yoke body radome is installed, this described radome cover places the top of stack iron core.
Preferred as technique scheme, the upper and lower surface of described iron yoke body all is equipped with cushion block, and described upper clamping piece and lower clamping piece are installed on the cushion block.
Preferred as technique scheme, described cushion block is insulator.
Preferred as technique scheme is equipped with suspension ring on the described upper clamping piece.
Preferred as technique scheme, described lower clamping piece is installed on the base.
Preferred as technique scheme, described lower clamping piece is installed on the base by bolt.
Preferred as technique scheme, described upper clamping piece and lower clamping piece are respectively two blocks of I-steel and consist of, and described upper clamping piece and lower clamping piece are clamped in respectively on the stack iron core, connect by screw rod between described two blocks of I-steel.
Preferred as technique scheme is equipped with binding post on the described iron yoke body.
Beneficial effect of the present invention is: be provided with radome in the present invention, this radome iron core that will superpose covers on wherein, prevent that it from carrying out electrion, has better security performance, this radome can prevent electrion and the damage that causes in addition, can increase the service life, and the safe distance between the cabinet wall of the present invention and power distribution cabinet has shortened, the size that no longer needs to increase cabinet in the power distribution cabinet in design satisfy safe distance demand, can save the production cost of power distribution cabinet.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention
Fig. 2 is structural representation of the present invention
Among the figure: 1, stack iron core; 2, lower clamping piece; 3, upper clamping piece; 4, radome; 5, cushion block; 6, suspension ring; 7, base; 8, iron yoke body; 9, binding post
Embodiment:
Therefore the following stated does not limit protection scope of the present invention only for embodying the preferred embodiment of the principle of the invention
As shown in Figure 1, 2 for the embodiment of a kind of improved autotransformer of the present invention, it comprises stack iron core 1, described stack iron core 1 clamping is installed between the iron yoke body 8, the upper surface of iron yoke body 8 is equipped with upper clamping piece 3, the lower surface of described iron yoke body 8 is equipped with lower clamping piece 2, on the described iron yoke body 8 radome 4 is installed, these described radome 4 covers place the top of stack iron core 1.
Radome 4 can be made by any insulating material, and in present embodiment, this radome 4 is made by the thick epoxy plate processing of 5mm, in addition in the present embodiment, scribbles red insulating protection lacquer on the outer surface of iron yoke body 8.
The upper and lower surface of iron yoke body 8 all is equipped with cushion block 5, described upper clamping piece 3 and lower clamping piece 2 are installed on the cushion block 5, in present embodiment, upper clamping piece 3 and lower clamping piece 2 are respectively two blocks of I-steel and consist of, described upper clamping piece 3 and lower clamping piece 2 are clamped in respectively on the stack iron core 1, connect by screw rod between described two blocks of I-steel, adopt screw rod that two blocks of I-steel are connected and to strengthen whole installation strength.
At present embodiment, cushion block 5 is insulator.
Because stack iron core 1 weight ratio of transformer is larger, therefore can be very inconvenient in carrying, most applications need to by handling appliance, in order to make things convenient for handling, be equipped with suspension ring 6 on the upper clamping piece 3.
In addition, on the iron yoke body 8 binding post 9 is installed, this binding post 9 can conveniently be connected with electric wire.
Be provided with radome on of the present invention, this radome has insulation property, this radome iron core that will superpose covers on wherein, prevent that it from carrying out electrion, has better security performance, this radome can prevent electrion and the damage that causes in addition, can increase the service life, and the safe distance between the cabinet wall of the present invention and power distribution cabinet has shortened, the size that no longer needs to increase cabinet in the power distribution cabinet in design satisfy safe distance demand, can save the production cost of power distribution cabinet.
