Abstract
The utility model discloses a current transformer with double-layered external insulation. The current transformer comprises a transformer body, and is characterized in that a base is arranged at the bottom of the transformer body, four connection terminals are arranged on the lower right of the transformer body which is integrally cast with the base, the transformer body is divided into two layers, one is an epoxy resin layer, the other is a rubber layer which is arranged outside the epoxy resin layer, and the rubber layer is made of liquid silicone rubber. The current transformer is simple in structure and durable in use.
Description
Technical field
The utility model relates to a kind of instrument transformer, is specifically related to a kind of current transformer of double-deck external insulation.。
Background technology
The installation site of some instrument transformers, outdoor, requires product can adapt to outdoor running environment.Direct sunlight, wind, drench with rain, the external insulation performance that all has a strong impact on product such as filthy, the external insulation life-span of outdoor mutual inductor determines the useful life of whole product.Domestic first generation outdoor mutual inductor is oil immersed type, because this product is metal shell, external insulation mainly adds sealing ring by insulator, surface creepage distance little (the 10kV instrument transformer generally only has the 300mm left and right), the dirty property of its anti-electric arc and resistant is poor, under particular surroundings, be prone to dodge iron, electric discharge phenomena, make the insulator surface form the charing vestige, have a strong impact on the external insulation performance; Its seal is very easily aging, the oil seepage phenomenon often occurs, need to regularly carry out oiliness and can chemically examine and even change transformer oil, and later maintenance is pretty troublesome.Second generation outdoor mutual inductor is with the dry type mutual inductor of poured with epoxy resin insulation, with the oil immersed type of the first generation, compares, and properties of product have had large increase, there is no Seepage, and Product Precision also can reach requirement, but still there are a lot of problems in insulation aspect outside.Common epoxy resin can not be used out of doors, because of poor performance such as its UV resistant, anti-electric arcs, just there will be for a long time surperficial powder phenomenon-tion under direct sunlight, and the external insulation performance is descended rapidly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of current transformer of simple in structure, long-lived a kind of double-deck external insulation.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of current transformer of double-deck external insulation, comprise the instrument transformer body, it is characterized in that: described instrument transformer body bottom is provided with base, and the lower right of described instrument transformer body is provided with four binding posts, and described instrument transformer body and base are cast into one.
Described instrument transformer body is divided into two-layer, and wherein one deck is epoxy resin layer, and another layer is rubber layer.
Described rubber layer is located at the outside of epoxy resin layer.
Described rubber layer adopts fluid silicone rubber to make.
The beneficial effects of the utility model are: can avoid the flour phenomenon in the background technology by rubber layer, improve the performance of external insulation simultaneously, thereby also improve user's use safety.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
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.
As shown in Figure 1, a kind of current transformer of double-deck external insulation, comprise instrument transformer body 1, and instrument transformer body 1 bottom is provided with base 2, and the lower right of instrument transformer body 1 is provided with four binding posts 3, and instrument transformer body 1 is cast into one with base 2.Instrument transformer body 1 is divided into two-layer, and wherein one deck is epoxy resin layer 11, and another layer is rubber layer 12.Rubber layer 12 is located at the outside of epoxy resin layer 11.Rubber layer 12 adopts fluid silicone rubber to make.Can avoid the flour phenomenon in the background technology by rubber layer 12, improve the performance of external insulation simultaneously, thereby also improve user's use safety.
Above demonstration 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 in above-described embodiment and specification, describes 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.
