Abstract

The utility model belongs to assembly mounting technique field in transformer assembling process, particularly a kind of bushing current transformer mounting structure.This bushing current transformer mounting structure comprises case lid and bushing current transformer, it is characterized in that: described bushing current transformer hangs nut by four of being welded under case lid and is fixed on desired location via drawing screw rod and supporting plate, and side, case lid upper end is fixed with mutual inductor interstar connection box.Structure is simple, is convenient to outlet and easy to operate; Reduce the cost of transformer, also can reduce the whole height of transformer simultaneously.

Description

Bushing current transformer mounting structure
(1) technical field
The utility model relates to a kind of bushing current transformer mounting structure, belongs to assembly mounting technique field in transformer assembling process.
(2) background technology
Present stage, the mounting means that transformer middle sleeve formula current transformer often adopts is that case lid raises seat with special current transformer, bushing current transformer is arranged on and raises in seat cylinder, the advantage done like this is not by institute's band instrument transformer number quantitative limitation, shortcoming takies case lid space comparatively greatly, needs to weld special rising seat, particularly when transformer capacity is less, during case lid limited space, often difficult arrangement.In addition, when required bushing current transformer quantity be 1 ~ 2 or only need wherein a phase electrified current transformer time, due to structure, current transformer raises the height of seat and quantity can not reduce, will bring the increase of oil mass like this, production cost is corresponding increase also.
(3) summary of the invention
The utility model in order to make up the defect of prior art, provide a kind of structure simple, be convenient to outlet and effectively can reduce the bushing current transformer mounting structure of transformer whole height.
The utility model is achieved by the following technical solution:
A kind of bushing current transformer mounting structure, comprise case lid and bushing current transformer, it is characterized in that: described bushing current transformer hangs nut by four of being welded under case lid and is fixed on desired location via drawing screw rod and supporting plate, and side, case lid upper end is fixed with mutual inductor interstar connection box.
Wherein:
Mutual inductor interstar connection box is fixed by set bolt in described side, case lid upper end, adds its steadiness.
The utility model is realized by following operation principle: the space between case lid unshakable in one's determination under utilizing case lid, nut is hung by four of being welded under case lid, with drawing screw rod and supporting plate, bushing current transformer is fixed on desired location, mutual inductor interstar connection is drawn outside fuel tank by mutual inductor interstar connection box, reach the cost reducing transformer, also can reduce the object of the whole height of transformer simultaneously.
The utility model is applied to all power transformers, especially box lid type off circuit tap changing transfor mer.
The beneficial effects of the utility model are: structure is simple, are convenient to outlet and easy to operate; Reduce the cost of transformer, also can reduce the whole height of transformer simultaneously.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the utility model bushing current transformer mounting structure schematic diagram;
Accompanying drawing 2 is conventional sleeve tubular type current transformer installing structure schematic diagram.
In figure: 1, case lid; 2, bushing current transformer; 3, nut is hung; 4, screw rod is drawn; 5, supporting plate; 6, mutual inductor interstar connection box; 7, casing flange; 8, case lid flange; 9, seat is raised.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model bushing current transformer mounting structure as shown in Figure 1, comprise case lid 1 and bushing current transformer 2, described bushing current transformer 2 hangs nut 3 by four of being welded under case lid 1 and is fixed on desired location via drawing screw rod 4 and supporting plate 5, and mutual inductor interstar connection box 6 is fixed by set bolt in side, case lid 1 upper end.
Conventional sleeve tubular type current transformer installing structure as shown in Figure 2, comprises case lid 1, bushing current transformer 2, casing flange 7 and case lid flange 8, and bushing current transformer 2 is arranged on and raises in seat 9, raises seat 9 side and is provided with instrument transformer pull box 6.
Compared with conventional sleeve tubular type current transformer installing structure, the utility model utilizes the space between case lid 1 time iron core to case lid 1, nut 3 is hung by four of being welded under case lid 1, with drawing screw rod 4 and supporting plate 5, bushing current transformer 2 is fixed on desired location, mutual inductor interstar connection is drawn outside fuel tank by mutual inductor interstar connection box 6, reach the cost reducing transformer, also can reduce the object of the whole height of transformer simultaneously.

Claims (2)
