Abstract
The utility model relates to a GIS mutual inductor. According to an existing GIS mutual inductor, a single coil is placed in a customized stainless steel die, the steel die is heavy and inconvenient to assemble and disassemble, and consumed time is long; the coil of the existing mutual inductor needs to be fastened and tamped during assembly, and a lot of manpower and materials are needed. The GIS mutual inductor is characterized by comprising an inner shielding cylinder and a shielding bottom board base, the inner shielding cylinder is arranged on the shielding bottom board base, the circumference of the inner shielding cylinder is annularly provided with a first mutual inductor coil, a second mutual inductor coil and a third mutual inductor coil which are sequentially connected from top to bottom, and the bottom end of the third mutual inductor coil is connected with the shielding bottom board base. According to the GIS mutual inductor, only the portion connected with the shielding cylinder is solidified when the GIS mutual inductor is manufactured, a large amount of epoxy resin is saved, fastening, filling and assembling are not needed, forming is achieved at one time, a lot of materials and manpower cost are saved, and work efficiency is also improved.
Description
Technical field
The utility model relates to a kind of instrument transformer, especially a kind of GIS instrument transformer of epoxy encapsulation.
Background technology
Existing GIS instrument transformer is that single coil is positioned in the stainless steel mould of customization, then put into vaccum-pumping equipment through vacuumizing processing, and in vacuum environment, heat the epoxy resin mixed glue that perfusion configures again, also to heat afterwards the demoulding, then tangent plane grinding process again, could drop into preliminary use, when such instrument transformer is made, workload is large especially, steel mold weight is large, dismounting inconvenience, have reach 100kg more than, more than adding that mutual inductor coil can arrive 200kg, carrying is inconvenient; And heating in vacuum and demoulding time reach more than 48 hours, waste resource and time, resin mixture is put into vacuum tank and is also needed to heat 2 hours; The mould versatility of making is little, make a large amount of moulds, in order to general; While being exactly in addition mutual inductor coil assembling, want fastening tamping, need a large amount of artificial and materials, very loaded down with trivial details not easy to operate.
Summary of the invention
The purpose of this utility model is to provide a kind of convenience, good looking appearance and time saving and energy saving GIS instrument transformer of encapsulating.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of GIS instrument transformer, its special feature is: comprise shielding inner core and shielded backplane seat, described shielding inner core is vertically set on shielded backplane seat, on the circumference of described shielding inner core, be equipped with the first mutual inductor coil, the second mutual inductor coil and the 3rd mutual inductor coil that connect successively from top to bottom, the bottom of described the 3rd mutual inductor coil is connected with shielded backplane seat; Between described shielding inner core and the first mutual inductor coil, the second mutual inductor coil and the 3rd mutual inductor coil, be provided with epoxy resin layer.
The size of described the first mutual inductor coil, the second mutual inductor coil and the 3rd mutual inductor coil is identical and edge is mutually concordant.
?compared with prior art, the utlity model has following beneficial effect:
1) the utility model normal temperature cure is without heating in vacuum, without a large amount of heavy moulds of reply;
2) the utility model only solidifies with shielding cylinder joining part and saves a large amount of epoxy resin in the time making, and without fastening filling assembling, disposal molding, not only saves lot of materials and cost of labor, has also improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1. shield inner core; 2. shielded backplane seat; 3. the first mutual inductor coil; 4. the second mutual inductor coil; 5. the 3rd mutual inductor coil; 6. epoxy resin layer.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
A kind of GIS instrument transformer, comprise shielding inner core 1 and shielded backplane seat 2, described shielding inner core 1 is vertically set on shielded backplane seat 2, on the circumference of described shielding inner core 1, be equipped with the first mutual inductor coil 3, the second mutual inductor coil 4 and the 3rd mutual inductor coil 5 that connect successively from top to bottom, between shielding inner core 1 and the first mutual inductor coil 3, the second mutual inductor coil 4 and the 3rd mutual inductor coil 5, be provided with epoxy resin layer 6, the bottom of described the 3rd mutual inductor coil 5 is connected with shielded backplane seat 2.
The first mutual inductor coil 3 in the utility model, the second mutual inductor coil 4 are identical with the size of the 3rd mutual inductor coil 5, and its edge is mutually concordant.
In the time making this iron core, first produce the first mutual inductor coil 3, the second mutual inductor coil 4 and the 3rd mutual inductor coil 5, it is all sheathed on supporting shielding inner core 1, then when casting epoxy resin along the appropriate epoxy resin of gap disposal pouring between above-mentioned mutual inductor coil and shielding inner core 1.Then wait for that epoxy resin solidifies rear formation epoxy resin layer 6, has just completed the making of a set of GIS instrument transformer.
