Abstract

The utility model relates to an oil-immersed transformer provided with a self hoisting core. The oil-immersed transformer comprises a transformer oil tank and a transformer body, wherein the transformer body is arranged in the transformer oil tank; a tank cover is arranged at the top of the transformer oil tank; one or more lifting jacks are connected onto the two corresponding outsides of the transformer oil tank respectively; the lifting jacks are connected with the tank cover to lift up the tank cover for opening the transformer oil tank or to put down the tank cover for sealing the transformer oil tank. Self lifting jack structures on the side edges of the transformer oil tank are adopted, and used for supporting the tank cover and sealing the transformer oil tank, so as to meet the requirements of the transformer body in the transformer oil tank, such as maintaining, hoisting and opening; besides, the oil-immersed transformer is simple and stable in structure, convenient and safe in operation, and can hoist the transformer body in the transformer oil tank in real time. Therefore, the maintenance cost can be lowered and the maintenance efficiency can be improved.

Description

The oil-immersed type transformer with self suspended core apparatus

Technical field

The utility model relates to a kind of transformer, is a kind of oil-immersed type transformer with self suspended core apparatus specifically.

Background technology

The device body of oil-filled transformer (winding and iron core) is all contained in the fuel tank that is full of transformer oil, and fuel tank is comprised of case shell and case lid conventionally, and the device body of transformer is placed in case shell, after case lid need being opened, hangs out during the maintenance of device body.In transformer field of employment, cannot be in time or be equipped with specially boom hoisting for device body maintenance, maintenance difficulty, cost is high, efficiency is low.

Summary of the invention

For deficiency of the prior art, it is a kind of simple in structure, easy to operate that the utility model provides, and can lift by crane in real time device body in oil tank of transformer, improves the oil-immersed type transformer with self suspended core apparatus of overhaul efficiency.

The technical solution adopted in the utility model is: a kind of oil-immersed type transformer with self suspended core apparatus, comprise oil tank of transformer and transformer body, transformer body is arranged in oil tank of transformer, transformer oil box top is provided with case lid, its technical characterstic is to be connected with respectively an above jack on two corresponding outsides of described oil tank of transformer, and jack connects case lid and is and drives case lid to rise to open wide oil tank of transformer or decline encapsulated transformer fuel tank state.

Further, the moving case lid of the vertical link box cover strip of described jack is vertical lift state.

Further, the jack in described oil tank of transformer two corresponding outsides and tie point Central Symmetry on case lid of case lid.

Further, described case lid is provided with reinforcement.

Again further, described reinforcement extended line is by the jack in oil tank of transformer two corresponding outsides and the tie point of case lid.

Adopt above technical scheme, the utility model has the advantages that:

1, oil tank of transformer side arranges jack, and jack connects case lid, when needs are opened case lid, manually controls jack stand case lid, case lid can be opened, and is convenient to device body lifting in fuel tank, need not be equipped with special-purpose lifting appliance, reduces the cost of overhaul; Jack vertical top plays case lid, rapid operation simultaneously; The jack setting that is centrosymmetric, is conducive to guarantee the stability of jack-up case lid improve usage safety performance;

2, the reinforcement of corresponding jack and case lid tie point is set on case lid, and when the stressed jack-up of case lid, reinforcement plays the indeformable effect of protection case lid.

The utility model adopts oil tank of transformer side to carry jack structure, with jack supporting box cover encapsulated transformer fuel tank, meet the unpacking requirement of device body maintenance lifting in oil tank of transformer, it is simple in structure, stable, easy to operate, safety, can lift by crane in real time device body in oil tank of transformer, reduce the cost of overhaul, improve overhaul efficiency.
