Description
Technical field
The present invention relates to the compound insulating sleeve that a kind of American box type transformer is suitable for, is at prior art simplification structurally, this improvement aspect two of refining on function.
Background technology
At present, the sleeve pipe that domestic transformer industry is applied in American box type transformer is following the similar products of " transformer assembly " pattern compilation () of Shenyang Transformer Factory in October, 1976 establishment mostly, the design of eighties of last century the seventies deficiency is arranged certainly more;
1. prior art, complex structure; Press pattern compilation P
11Each member of contained BJ35KV/400A sleeve pipe statistics has 29 kinds more than, and main member of the present invention has only 6 kinds, by contrast, needs to simplify on complicated and simple clearly demarcated, the visible structure.
2. prior art, the functional reliability deficiency; Prior art similar products structure usually adopts insulator as external insulation umbrella in above-mentioned 1., and it makes the thick and crisp damage that easily collapses of property, and strength reliability is poor; Exist the sealing of four roads and every place all to determine to need to refine on its seepage, lower, the visible function of antiseepage reliability again in its structure.
Summary of the invention
The present invention provides a kind of compound insulating sleeve for the deficiency that solves above-mentioned prior art existence.
The present invention finishes the target of above-mentioned proposition to take following technical scheme;
It comprises: conducting rod 1, insulating core 2, insulated umbrella 3, sealing ring 4, equal gland 5, wiring nut 6; It is characterized in that: conducting rod 1 is insulated external diameter surface that umbrella 3 surrounds length L and is shaped on and continues annular rill, even few length portion section hoop at 〉=0.4L overlapping insulating core 2, and its outer compound insulated umbrella 3 that is shaped on.
Make the method for compound insulating sleeve: the main material of its application is the conducting rod 1 that makes of copper and alloy thereof, equal insulated umbrella 3 of making of insulating core 2 engineering plastics that make of gland 5, wiring nut 6, resin or polyester or polyamide and glass fiber or the compound or independent processing of insulating paper, the sealing ring 4 that oil resistant rubber makes; This method comprises the main technique step of following order:
The lasting annular rill of processing conducting rod two ends screw thread and be insulated on the external diameter length L that pack encloses 〉=0.4L portion section, and make the conducting rod surface oxidation-resistant and handle.
At conducting rod annular rill, on its length 〉=0.4L portion section, and make its radial thickness reach requirement of withstand voltage resin or polyester or polyamide and glass fiber or the compound or independent processing of insulating paper, make the insulating core hoop and be enclosed within composite component on the conducting rod.
The insulating core hoop is enclosed within composite component on the conducting rod, makes dried by its technical conditions, and carry out shaping.
Adopt thermostatically controlled hot-die, by selected engineering plastics processing three elements, promptly time, pressure, temperature are moulded the system insulated umbrella, and umbrella is thick 〉=3 millimeters, umbrella number 〉=3.
At conducting rod both ends or one end suit sealing ring 4, the equal gland 5 spacing sealing rings that compress of screwing on separately more then screw on the assembling that wiring nut 6 has just been finished compound insulating sleeve.
Outside the big footpath of insulated umbrella umbrella is covered in, the path umbrella keep away in interior, be in interval alternative distribution up and down, the purposes of compound insulating sleeve is suitable for American box type transformer external cable.
Conducting rod, insulating core, insulated umbrella impose lamination integration technology; And thereon port and (or) lower port sets up sealing ring 4 again, by equal gland 5 it imposed definite value pressure in the elastic range; The purposes of compound insulating sleeve is more suitable in the American box type transformer external cable of wind power generation.
Described by above technical scheme; conducting rod also can adopt metal good conductors such as aluminium and aluminium alloy to make; a kind of copper clad aluminum conductor is particularly arranged at present; it has used the collection skin principle of conductor with current delivery; make its conductivity approach the level of the solid full copper conductor of equal diameter; with regard to patent, adopt this copper clad aluminum conductor to make conducting rod and also fall into protection scope of the present invention.
