Summary of the invention
In view of this, the object of this invention is to provide a kind of compact conformation, save space, meets the transformer Outgoing Line Unit of hermetically sealed, all insulation and anti-filthy performance requirement.
The present invention adopts following scheme to realize: a kind of transformer Outgoing Line Unit, the case lid that comprises oil tank of transformer, the wire hole for high-voltage connection cable outlet is offered in the high-pressure side of described case lid, on the high-pressure side of described case lid, be also provided with the rising seat that covers on wire hole top, described rising seat sidewall is provided with a hole, in rising seat, be provided with along continuous straight runs and be arranged on the inner cone socket on described seat hole, socket electrode on described inner cone socket is connected with high-voltage connection cable electrical, the seat lateral wall that raises is provided with and coordinates the inner cone of installing to insulate silently with described inner cone socket, in described inner cone insulation silently, be inserted with inner cone plugging formula terminal.
Further, described rising seat top is provided with dismountable cover plate, and this cover plate is mounted on the adpting flange on the seat top that raises by screw bolt and nut, between cover plate and adpting flange, is folded with sealing ring.
Further, on upper another sidewall relative with described seat hole of the described seat that raises, be connected with connection tracheae.
Further, described case lid downside is fixed with support plate, is connected with for high-voltage connection cable is carried out to spacing wire clamp on described support plate.
Compared with prior art, the present invention has following beneficial effect: this transformer Outgoing Line Unit is reasonable in design, and compact conformation is saved approximately 50% terminal space, has dwindled transformer overall dimension simultaneously, has facilitated installation and transportation; And meet the performance requirements such as hermetically sealed, all insulation and anti-filth, be applicable to the filthy serious occasion such as petrochemical industry, Ferrous Metallurgy, cement building material and use.
