Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1-Fig. 8, the utility model comprises outer casing base 1, described outer casing base 1 is divided into three cavitys 23, coil 3 is provided with in each described cavity 23, the top of described outer casing base 1 is provided with cover plate 2, described cover plate 2 is provided with cavity 23 described with three corresponding window 32, described cover plate 2 is provided with one group and draws pin 34, described in draw pin 34 and be fixed on described cover plate 2.
The described pin 34 that draws comprises that pin 34a is drawn in outside, pin 34b is drawn in inner side and turning 34c, described in draw pin 34 and be fixed on the boss 31 bottom described cover plate 2 by described turning 34c.
The peripheral protective case 21 that described outer casing base 1 comprises macromolecular material and the body of wall 22 that described outer casing base 1 is isolated.
The both sides of described body of wall 22 are provided with groove 24.
The thickness of described cover plate 2 equals the height of described body of wall 22 lower than described peripheral protective case 21.
Described cover plate 2 is provided with circular hole and indicates 33 points.
Described coil 3 comprises the iron core 35 of tape insulation layer 37, primary coil and secondary coil.
Described cover plate 2 is the cover plate of macromolecule BT material, described in draw the tin pin that pin 34 is plated surface insulating varnish.
Described insulating barrier 37 is epoxy package or polyester film or PVC, and described iron core 35 is nano-crystalline alloy iron core, and described primary coil and secondary coil are enamelled wire 37.
Described enamelled wire 37 is the copper cash of plated surface insulating varnish.
Outer casing base 1 is generally BT material, and concrete is flame-retardant PBT material, and body of wall 22 grooves on two sides 24 and partial cover plate boss 31 match.
The size of cover plate 2 just in time can be embedded in outer casing base 1, and by the support of body of wall 22, groove 24 and part boss 37 chimeric, realizes the assembling of cover plate 2 and outer casing base 1.Window 32 corresponding with the cavity 23 of three on outer casing base 1, to meet the needs of later stage infusion epoxy resin for three on cover plate 2.Window compartment between 32 and body of wall 22 thickness matches.
On cover plate 31 with a circular hole identification point 33 for determining the output signal of respectively drawing pin 32, draw pin 34 and have 12.Two adjacent spacing of drawing between pin 34 are 2.54mm or 12.7mm, match with row's needle socket spacing, can the directly upper use of the row of being inserted into mother to realize instrument transformer of the present invention.
Coil 3 is combined by iron core 35 and the armature winding be wound on iron core 35 and secondary winding, and wherein, primary and secondary winding is enamelled wire 36.Directly can not contact between iron core 35 with enamelled wire 36, prevent the wearing and tearing of enamelled wire 36 in winding process from hanging up, more importantly as medium, discharge breakdown between primary and secondary winding be lost efficacy by iron core conductor in order to prevent.This insulating barrier 37 just requiring iron core 35 additional has withstand voltage, resistant to elevated temperatures effect, usually selects epoxy package.
Concrete, outer casing base 1 and cover plate 2 are formed by mold injection; Iron core 45 is by the coiling of ultracrystallite band and carry out strong magnetic anneal process and form; Primary and secondary winding adopts high-strength magnetic enamelled wire 36.
The wire wound of primary and secondary winding, after detecting line circle compensation deals of going forward side by side, to draw on pin and soldering four of each cavity 23 correspondence by the good coil 3 of coiling.Instrument transformer of the present invention define lead-in wire and the corresponding relation drawing pin be just, two lead-in wires of level winding receive cover plate 2 and draw on pin 34 with circular hole identification point 33 side, the lead-in wire of secondary winding transformer is received on two lead-in wires of opposite side.Same process done by three coils 3.Then, the cover plate 2 of upper for welding coil is fitted in outer casing base 1, completes assembly work.Finally, epoxy resin on Reperfu-sion, seal protection, completes the manufacture of the utility model instrument transformer.
