Abstract

The utility model discloses a novel amorphous alloy distribution transformer core which comprises an upper clamp (1), a lower clamp (2), amorphous iron cores (3) arranged in grooves of the upper and lower clamps, square coils (4) sleeved on the amorphous iron cores, support bars (5) for tightly supporting the square coils and the amorphous iron cores, insulating isolating plates (6) arranged between each two square coils, cushion blocks (7) arranged at the upper and lower end surfaces of the square coils, screws (8) penetrating through the upper and lower clamps and screw nuts arranged at the screws, the other end surfaces of the cushion blocks are respectively contacted with the end surfaces of the upper and lower clamps. The novel amorphous alloy distribution transformer core is characterized in that the square coils are square shapes with inner concaves. The novel amorphous alloy distribution transformer core has the beneficial effects that the coils are concave, so that the actual appearance sizes of the coils are reduced; and meanwhile isolating plates are adopted for insulation between phases, so that the phase distance is reduced, then the widths of the iron cores are reduced, the use quantity of the iron cores is reduced, and the product cost is greatly reduced.

Description

Novel amorphous alloy distribution transformer device core

Technical field

The utility model relates to a kind of Novel amorphous alloy distribution transformer device core.

Background technology

At present, there is following drawback in three-phase oil-immersed amorphous alloy distribution transformer: the between phase and phase employing air insulation of winding, for guaranteeing insulation effect, leave larger spacing, so that the width of iron core increases, the increase of iron core width causes the consumption of amorphous alloy iron core also to increase, and then raises the cost of transformer.

The utility model content

The purpose of this utility model is exactly in order to address the above problem, and a kind of Novel amorphous alloy distribution transformer device core is provided.

To achieve these goals, the utility model adopts following technical scheme:

A kind of Novel amorphous alloy distribution transformer device core, it comprises, lower clamping piece (1,2), be located at the amorphous iron core (3) in the folder from top to bottom groove, be sheathed on the square coil (4) of amorphous iron core, stay (5) with square coil and amorphous iron core stretching, be located at the in twos insulating barrier between the square coil (6), the cushion block of the upper and lower end face of the side's of being located at coil (7), the nut (9) that is arranged in the screw rod (8) of folder from top to bottom and is located at screw rod, wherein the cushion block other end respectively with the folder from top to bottom end contact, it is characterized in that described side's coil is the square shape with indent.

The beneficial effects of the utility model are: coil is spill, and the coil actual outer dimensions is reduced, and alternate employing barrier insulation reduces phase spacing simultaneously, thereby so that the iron core width reduces, the iron core consumption obtains descending, and product cost is significantly reduced.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 1-4b, a kind of Novel amorphous alloy distribution transformer device core, it comprises,

lower clamping piece

1,2, be located at the amorphous iron core 3 in the folder from top to bottom groove, be sheathed on the square coil 4 of amorphous iron core, stay 5 with square coil and amorphous iron core stretching, be located at the in twos insulating barrier between the square coil 6, the cushion block 7(cushion block other end of the upper and lower end face of the side's of being located at coil respectively with the folder from top to bottom end contact), the nut 9 that is arranged in the screw rod 8 of folder from top to bottom and is located at screw rod, the screw rod attaching nut, so that folder from top to bottom and cushion block are with square coil, amorphous iron core is fixed between the folder from top to bottom, described side's coil is the square shape with indent, side's coil packs in the amorphous iron core after by the overlap joint mouth of opening amorphous iron core top, side's coil is placed insulating barrier between any two, because the profile of square coil is narrower than evagination coil, be that size Q is less, namely size W is less, so that the square hole width dimensions E of amorphous iron core is descended, after adopting barrier insulation between the coil, spaced apart is that distance R between coil and the coil is little during than air insulation, also so that the width E of iron core descended, the reduction of iron core width, be reduced so that the consumption of iron core is corresponding, thereby reduce manufacturing cost.

The above only is preferred implementation of the present utility model, and protection range of the present utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to protection range of the present utility model.For a person skilled in the art, some improvement of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvement also should be considered as protection range of the present utility model.
