Match with the seal groove that is arranged on lid bottom, provided with two binding posts at the top of the lid, lid portion inside is provided with cavity,
The binding post includes setting columnae medialis and the mixed lateral column being arranged at the top of lid, the mixed lateral column of the binding post in the cavities
Be arranged with insulating sleeve on outer surface, the columnae medialis of the binding post and be arranged in lid portion inside cavity the one of binding post
Side correspondence is connected, the connection corresponding with the high pressure winding and low pressure winding of transformer coil of the opposite side of the binding post, described
Lid, sealing ring, install the first bolt hole and the second bolt hole be correspondingly arranged on interlayer and casing, lid, sealing ring and
Interlayer is installed by the first bolt hole to be connected, lid, sealing ring, installation interlayer are connected with casing by the second bolt hole；
It is preferred that, it is provided with suspension hook at the top of the lid.
What the present invention was brought has the beneficial effect that：Installation interlayer and sealing ring are provided between casing and lid, interlayer is installed
Bottom, which is provided with installing plate, installing plate, is fixedly connected with transformer coil, installs and is evenly arranged with drain tap on the wall of interlayer side, institute
State and be correspondingly arranged on the first bolt hole and the second bolt hole, lid, sealing ring on lid, sealing ring, installation interlayer and casing
It is connected with interlayer is installed by the first bolt hole, lid, sealing ring, installation interlayer are connected with casing by the second bolt hole
Connect, when transformer breaks down, unload the bolt on the second bolt hole, with loop wheel machine by suspension hook by lid, sealing ring and peace
Clamping layer, which is hung out, to be overhauled, and while installation interlayer is hung out, is installed transformer oil original in interlayer and is passed through drain tap stream
Return in transformer-cabinet, without in advance discharging transformer oil, simplify step cumbersome during conventional Repair of Transformer, improve
Operating efficiency, has saved human cost；Lid, sealing ring and unique sealing structure between interlayer is installed so that lid, close
Sealing property is excellent between seal and installation interlayer, and the columnae medialis of binding post is arranged in lid cavity, is arranged on lid top
The mixed lateral column in portion is arranged with insulating sleeve again, greatly promotes whole device sealing property, makes transformer oil in day-to-day operation
It is difficult to be oxidized, so as to be greatly reduced because changing the expense that transformer oil is brought, reduce transformer station high-voltage side bus and brought
Cost.
