Abstract

The utility model relates to a device positioning structure of a large transformer, belonging to the transformer manufacturing technical field, comprising an iron core clamping piece (6), a fixation plate (4), a fixation drawing plate (3) and a reinforcement plate (1), wherein the two ends of each iron core clamping piece are welded with screwed fixation plates and the fixation drawing plate is mounted on the welded fixation plates and the clamping piece at the high pressure side is connected with the clamping piece at the lower pressure side and a screw hole is opened in the middle of the fixation drawing plate the reinforcement plate (1) is welded at the fixation drawing plate outside a side oil-box wall (8) and through holes are opened on the oil-box wall and the reinforcement plate. The bolt with enough strength passes through the hole from the outside of the oil-box and is fastened on the fixation drawing plate and then the bolt is welded on the reinforcement plate from the outside of the oil-box to prevent oil leakage. The side of the device connects the device with the oil-box together and the fixation drawing plate ensures the fastening force of the high, lower pressure side clamping pieces and more important, four corners of the device are more positioned and reinforced and the transformer can resist impact along the forward and backward directions during ocean shipping and land long-distance transporting.

Description

A kind of device body positioning structure of high-power transformer

Affiliated technical field:

The utility model relates to a kind of device body positioning structure of high-power transformer, belongs to technical field of transformer manufacturing.

Background technology:

Impulse inertia power is excessive in the transformer transportation, can produce in various degree whole displacement or distortion to the device body of high-power transformer, and some displacement and distortion can not be repaired.This not only has the possibility that reduces transformer performance, and What is more can cause transformer integral body to be scrapped.

The utility model content:

The utility model purpose provides a kind of device body positioning structure of high-power transformer, improves the positioning and fixing reliability of transformer body, solves the problems referred to above that exist in the background technology.

The technical solution of the utility model is:

The device body positioning structure of high-power transformer comprises core clamping, fixed head, fixedly arm-tie, stiffener, threaded fixed head is welded at the two ends of each folder unshakable in one's determination, fixedly arm-tie is installed on the fixed head that is welded, the folder of high-pressure side and low-pressure side is coupled together, fixedly the arm-tie middle part has screwed hole, at fuel tank tank wall fixed outside arm-tie place, side weldering stiffener, fuel tank tank wall and stiffener are opened the hole.

The enough bolt of working strength penetrates perforate from the fuel tank outside, be fastened on fixedly on the arm-tie, then from the fuel tank outside with stud weld extremely on stiffener, in case leak-stopping oil.

The beneficial effects of the utility model: the utility model connects as one the side of device body with device body and fuel tank; The fixedly use of arm-tie has guaranteed the power of stepping up of high and low pressure side folder, the more important thing is by increasing the location of carrying out on four angles of device body and reinforces, and transformer can resist that fore-and-aft direction impacts in the long-distance fortune of transport by sea and land.

Description of drawings:

Fig. 1 is the utility model user mode schematic diagram;

Fig. 2 is the utility model embodiment schematic diagram.

Among the figure: stiffener 1, bolt 1, fixedly arm-tie 3, fixed head 4, locating pin 5, core clamping 6, bolt 27, fuel tank tank wall 8.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.

In an embodiment, the device body positioning structure of high-power transformer comprises core clamping 6, fixed head 4, fixedly arm-tie 3, stiffener 1, threaded fixed head is welded at the two ends of each folder unshakable in one's determination, fixedly arm-tie is installed on the fixed head that is welded, the folder of high-pressure side and low-pressure side is coupled together, fixedly the arm-tie middle part has screwed hole, and at side fuel tank tank wall 8 fixed outside arm-tie places weldering stiffener, fuel tank tank wall and stiffener are opened the hole.The enough bolt 1 of working strength penetrates perforate from the fuel tank outside, is fastened on fixedly on the arm-tie, welds extremely on stiffener, in case leak-stopping oil from the fuel tank outside with bolt 1 then.

Claims

1. the device body positioning structure of a high-power transformer, it is characterized in that comprising core clamping (6), fixed head (4), fixedly arm-tie (3), stiffener (1), threaded fixed head is welded at the two ends of each folder unshakable in one's determination, fixedly arm-tie is installed on the fixed head that is welded, the folder of high-pressure side and low-pressure side is coupled together, fixedly the arm-tie middle part has screwed hole, and at side fuel tank tank wall (8) fixed outside arm-tie place weldering stiffener, fuel tank tank wall and stiffener are opened the hole.
