Abstract
The utility model discloses a reversely-installed current transformer installation structure. The reversely-installed current transformer installation structure comprises an ascending flanged base. A transformer core is arranged in the ascending flanged base. An insulation piece is arranged outside the transformer core in a surrounding mode. The bottom of the transformer core is supported by a supporting board. A fixed board is arranged on the inner wall of the ascending flanged base. One end of the fixed board is fixed to the inner wall of the ascending flanged base and the other end of the fixed board is fixed to the supporting board. According to the reversely-installed current transformer installation structure, the shortages that a prior transformer bushing type current transformer is positively installed, the number of sealing faces is large, and oil leakage is prone to occurrence are overcome, the problem that a fixed board in a common reversely-installed ascending flanged base is large in occupied space is solved, the use ratio of inner space of the ascending flanged base is increased, the size of the ascending flanged base is effectively reduced, and the oil mass of a transformer is reduced. The reversely-installed current transformer installation structure is simple, easy to install, capable of reducing cost and high in universality.
Description
Technical field
The utility model relates to current transformer installing structure field, is specially a kind of flip-over type current transformer installing structure.
Background technology
Bushing current transformer is the composition vitals of power transformer product, and the structure of instrument transformer and geometry directly affect external styling and the presentation quality of transformer.Optimize instrument transformer structure, carry out the important content that standardization, standardization, Seriation Design are also transformer device structure standardization efforts.
The mounting means of bushing current transformer is divided into positive-installed and flip-over type conventionally.Positive-installed structure, instrument transformer fuse packs into from the seat top that raises, and the seat upper flange that raises is with bolts, and easily there is leakage of oil in sealing surface; Flip-over type structure, instrument transformer fuse packs into from the seat bottom that raises, fix by supporting plate, original flip-over type rising seat inside need be welded and fixed plate, take the very large space of seat inside that raises, need the corresponding instrument transformer fuse overall dimension of dwindling, reduced the seat inner space utilance that raises, transformer oil consumption is more.For avoiding above-mentioned situation to occur, be necessary very much instrument transformer structure to make further improvements.
Utility model content
The purpose of this utility model is to provide a kind of flip-over type current transformer installing structure, the problem existing to solve prior art.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of flip-over type current transformer installing structure, in including, there is the rising seat of cavity, it is characterized in that: the instrument transformer fuse that is provided with current transformer in the seat that raises, in described rising seat, be also provided with insulating part, supporting plate, it is outer with location stretching instrument transformer fuse that described insulating part is trapped among instrument transformer fuse, described supporting plate is supported on instrument transformer fuse bottom, the rising seat inwall of supporting plate below is provided with fixed head, fixed head one end is fixed on and is raise on seat inwall by securing member, and the fixed head other end is fixed on supporting plate by spacing fastening bolt.
Described a kind of flip-over type current transformer installing structure, is characterized in that: described fixed head is bent plate shape.
The utility model has the following advantages:
1, solved positive-installed and raise after the assembling of seat mounting flange, the problem of bolted sealing surface possibility leakage of oil.
2, improve a conventional flip-over type rising seat inwall and be welded and fixed plate, affected the problem that instrument transformer fuse is installed, saved the seat inner space that raises, reduced innage.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model supporting plate is connected enlarged diagram with fixed head.
Embodiment
As shown in Figure 1 and Figure 2.A kind of flip-over type current transformer installing structure, in including, there is the rising seat 1 of cavity, in rising seat 1, be provided with the instrument transformer fuse 2 of current transformer, in rising seat 1, be also provided with insulating part 3, supporting plate 4, it is outer with location stretching instrument transformer fuse 2 that insulating part 3 is trapped among instrument transformer fuse 2, supporting plate 4 is supported on instrument transformer fuse 2 bottoms, rising seat 1 inwall of supporting plate 4 belows is provided with the fixed head 6 of bent plate shape, fixed head 6 one end are fixed on and are raise on seat 1 inwall by securing member 7, and fixed head 6 other ends are fixed on supporting plate 4 by spacing fastening bolt 5.
The utility model is in the time of assembling, instrument transformer fuse is packed into and raise in seat, with insulating part by instrument transformer fuse location stretching, avoid instrument transformer fuse horizontal jitter, and then pack supporting plate into, with securing member by fixed head be arranged on raise seat inwall on, finally with spacing fastening bolt by fixed head to supporting plate carry out spacing and compression, avoid instrument transformer fuse vertically to rock.
Claims (2)
1. a flip-over type current transformer installing structure, in including, there is the rising seat of cavity, it is characterized in that: the instrument transformer fuse that is provided with current transformer in the seat that raises, in described rising seat, be also provided with insulating part, supporting plate, it is outer with location stretching instrument transformer fuse that described insulating part is trapped among instrument transformer fuse, described supporting plate is supported on instrument transformer fuse bottom, the rising seat inwall of supporting plate below is provided with fixed head, fixed head one end is fixed on and is raise on seat inwall by securing member, and the fixed head other end is fixed on supporting plate by spacing fastening bolt.
