Embodiment Construction
[0016] Such as Figure 1 ~ Figure 4 Shown are the steps for making high-voltage lead wires for dry transformers: the first step is to fix the copper tube on the bending master 2 on the bending table through the fixing clamp seat 3, and the size of the end is positioned to the required size; the second step is to rotate Bending the swivel seat 1 until it turns to the bending limiter 5 to complete the first bend of the copper pipe; the third step is to re-clamp the copper pipe after the first bend, that is, put the curved angle after the first bend close to the second bend. Bend the positioning plate 4; the fourth step, turn the bending swivel 1 until the bending limiter 5, and complete the second bend of the copper pipe.
[0017] The structure of the present invention uses copper tubes (diameter Φ16mm×1.5) instead of copper rods (diameter Φ16mm) under the condition of ensuring the required current density of high-voltage leads, which not only saves materials, but also reduces t...

The invention relates to a method for manufacturing high-voltage lead wires of a dry-type transformer, which uses copper pipes to replace the copper rods to manufacture the lead wires of the dry-type transformer. The method comprises the following steps of: 1, fixing a copper pipe on a bent explorator of a workbench through a fixed clamping seat; 2, rotating the bent rotary seat until to the bent limiting explorator, and completing the first bending of the copper pipe; 3. renewably clamping the copper pipe with the first bending, i.e. abutting the bending corner of the first bending onto a secondary bending positioning plate; and 4. rotating the bent rotary seat until the limiting explorator, and completing the secondary bending of the copper pipe. Under the condition of ensuring the current cross section of the high-voltage lead wires of the dry-type transformer, the invention uses the copper pipes to replace the copper rods to manufacture the high-voltage lead wires of the dry-type transformer, has no need of using the equipment like a bending machine, and also lowers the consumption of copper materials of the high-voltage lead wires, thereby fully saving energy and materials.
Description
technical field [0001] The invention relates to a method for making a dry-variable high-voltage lead wire. Background technique [0002] The competition in the transformer manufacturing industry is becoming increasingly fierce. Not only the quality of transformer products must be considered, but also the manufacturing cost is the focus of all manufacturers. Cheap and high-quality products are bound to be in a favorable position in the market competition. Therefore, in the manufacture of transformers, efforts to pay attention to every detail will bring certain results. As far as dry variable high voltage leads are concerned, copper rods were used in the past. Because of the high bending strength of copper rods, they need to be bent with a bending machine, and copper rods consume more copper. Now copper tubes are used instead of copper rods. , not only can realize the bending of the copper pipe with simple tooling, but also save a lot of copper. Contents of the invention ...
