Abstract

The utility model discloses a lower portion positioning structure used when a power transformer is put into an oil tank. The lower portion positioning structure used when the power transformer is put into the oil tank comprises the oil tank and an iron core lower clamp piece. A plurality of steel pipes are connected at the bottom of the oil tank in a welded mode, a plurality of cone-shaped positioning nails corresponding to positions of the steel pipes are connected under the iron core lower clamp piece in a welded mode, and insulating cardboards and polyester rings are placed in the steel pipes in sequence. The cone-shaped positioning nails are aligned to the centers of the steel pipes and placed into the steel pipes, and then clamping is achieved and electric insulation performance between the insulating cardboards and the polyester rings is guaranteed. When the lower portion positioning structure used when the power transformer is put into the oil tank is installed, the placing of the insulating cardboards and the polyester rings is completed, then the positioning nails are aligned to the centers of the steel pipes, and finally a body of the power transformer can be placed down. The lower portion positioning structure used when the power transformer is put into the oil tank has the advantages of being small in size, simple in structure, convenient to manufacture, easy to install, time-saving, and effort-saving.

Description

Bottom location structure when power transformer is put into fuel tank

Technical field

The utility model relates to the power transformer technical field, the bottom location structure when relating in particular to a kind of power transformer and putting into fuel tank.

Background technology

Transformer need to have the lower positioner that coordinates with it when putting into fuel tank.As shown in Figure 1, traditional lower location structure is in the threaded locating pin of fuel tank bottom welding, perforate on lower clamping piece, when the device body falls into fuel tank, lower locating pin is passed the perforate of lower clamping piece, be encased inside the insulating pad of suitable thickness in lower locating pin and lower clamping piece perforate gap, guaranteeing between the two not can displacement, then fixing to realize lower positioning function with nut.This operating process is loaded down with trivial details, and is high to requirement on machining accuracy, and inconvenience is installed, inefficiency.

The utility model content

The utility model purpose is exactly in order to make up the defective of prior art, the bottom location structure when providing a kind of convenient power transformer of installing to put into fuel tank.

The utility model is achieved through the following technical solutions:

Bottom location structure when a kind of power transformer is put into fuel tank, include fuel tank and iron core lower clamping piece, described fuel tank bottom is welded with a plurality of steel pipes, described iron core lower clamping piece below is welded with a plurality of taper locating pins corresponding with the steel pipe position, put into successively insulating board and polyester circle in described steel pipe, the taper locating pin is aimed at the steel pipe center put into wherein, realize chucking and guarantee between the two electrical insulation properties.

Described steel pipe is four, is evenly distributed in bottom fuel tank.

The utility model has the advantages that: when the utility model is installed, with insulating board and polyester circle place complete after, locating pin is aimed at the steel pipe center, fall the device body and get final product, have a volume little, simple in structure, easy to make, be easy to installation, time saving and energy saving advantage.
