[0004] (1) In the process of manually welding the heat dissipation pipe, the heat dissipation pipe is manually inserted into the welding hole of the oil tank, and then the heat dissipation pipe is welded together with the transformer oil tank. The process of inserting and welding the heat dissipation pipe is cumbersome, and only A heat pipe can be plugged and welded, so that time is wasted when welding the heat pipe;
[0005] (2) When using welding equipment to weld the heat dissipation pipe, the existing welding equipment usually only uses the method of clamping the two sides of the heat dissipation pipe to fix the heat dissipation pipe. A large amount of heat is generated during the welding process of the heat dissipation pipe, which leads to heat generation during welding of the heat dissipation pipe. Deformation makes the heat pipe welding unqualified

Embodiment Construction
[0041] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following combination Figure 1 to Figure 11 , to further elaborate the present invention.
[0042] A method for manufacturing a heat dissipation and cooling system for a power transformer, the specific manufacturing method is as follows:
[0043] S1. Adjust the welding position: manually rotate and fix the hand wheel 3416, so that the installation rod 33 is separated from the installation block 3411, thereby adjusting the position of the installation block 3411 on the installation rod 33, and then adjusting the welding position of the heat pipe;
[0044] S2. Loading: After the adjustment of the welding position is completed, manually fix the transformer box in the installation frame 2, and manually place the upper end of the heat dissipation pipe in the support head 3428, so that the middle part of the heat dissipation pipe is stuck in th...

The invention relates to a method for manufacturing a power transformer heat dissipation and cooling system, which includes a workbench, a mounting frame and two welding support devices. The supporting device is installed on the workbench by means of sliding fit. The invention provides a method for manufacturing a heat dissipation and cooling system for a power transformer, which can solve the problem of inserting the hole first and then welding during manual welding, which makes the insertion and welding process of the heat dissipation pipe cumbersome, and can only be inserted and connected manually once. Welding a radiating pipe wastes time when welding the radiating pipe, and the existing welding equipment usually only fixes the radiating pipe by clamping both sides of the radiating pipe. A large amount of heat is generated during the welding process of the radiating pipe, which leads to the Welding may cause thermal deformation, which makes the heat pipe welding unqualified and other problems.
Description
technical field [0001] The invention relates to the technical field of power transformer processing, in particular to a method for manufacturing a heat dissipation and cooling system of a power transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. The main function of the power transformer is To transmit electric energy, the power transformer will generate a lot of heat when it is working. When the temperature is too high, it will cause damage to the power transformer. Therefore, it is necessary to immerse the body of the transformer in a closed oil tank filled with transformer oil, and pass the cooling pipe outside the oil tank. The generated heat is dissipated, and the fuel tank and heat pipe are welded together. [0003] When manufacturing the heat dissipation and cooling system of the...
