Abstract
The utility model relates to a zero sequence mutual inductor fixing device which relates to the field of power grid protection technology. The zero sequence mutual inductor fixing device comprises a zero sequence mutual inductor and an epoxy resin box body. The zero sequence mutual inductor fixing device is characterized in that the zero sequence mutual inductor is poured and fixed on an epoxy resin box bottom plate in the epoxy resin box body; and four corners of the epoxy resin box bottom plate are provided with through holes. In the zero sequence mutual inductor fixing device, the zero sequence mutual inductor is poured and fixed on an epoxy resin box bottom plate, so that the zero sequence mutual inductor can be prevented from rolling so as to solve the problem that the use is easy to be affected as the zero sequence mutual inductor can not be fixed.
Description
Technical field:
The utility model relates to the electric network protection technical field, is specifically related to a kind of zero-sequence transformer fixture.
Background technology:
In China; along with deepening constantly of city net, the upgrading of rural power grids; reliability and fail safe in the power supply in service of power distribution network improve constantly; in circuit protection device; vital parts are zero-sequence transformer; the zero-sequence transformer of using in the present known mold cased circuit breaker is unfixing; directly be suspended on the conductor that passes the zero-sequence transformer coil; or be bonded at base bottom with glue; because coil neither one fixed position, thereby so easy generation rolling can have influence on the later normal use of product.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of zero-sequence transformer fixture.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of zero-sequence transformer fixture comprises zero-sequence transformer, epoxy resin casing, it is characterized in that: described zero-sequence transformer is fixed on the epoxy resin box plate by cast in the epoxy resin casing, has through hole on four jiaos of the epoxy resin box plates.
The beneficial effects of the utility model are: owing to adopted the zero-sequence transformer cast is fixed on the epoxy resin box plate, can prevents the zero-sequence transformer rolling, can't fix the problem that easy influence is used thereby solved.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of zero-sequence transformer fixture comprises zero-sequence transformer 3, epoxy resin casing 1, and zero-sequence transformer 3 is fixed on the epoxy resin box plate 2 by cast in epoxy resin casing 1, have through hole 4 on 2 four jiaos of the epoxy resin box plates, be used for fixing and connect other parts.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
