Embodiment 1

[0035] Such as figure 1 As shown, the manufacturing process of the anti-sudden short-circuit amorphous alloy transformer coil includes the following steps:

[0036] Step 1. Low-voltage coil winding:

[0037] a. Skeleton installation, put a 3mm thick skeleton into the winding mold, align it with the foil and interlayer insulation and fix it, and wrap a layer of full adhesive paper on the skeleton. The skeleton is a hard epoxy glass cloth tube. The interlayer insulation is fully glued paper. Full-adhesive paper can meet the insulation strength between layers of low-voltage coils and ensure the compactness and resistance to external forces of low-voltage coils. Because of its super-strong adhesive force after heating, it can ensure the integrity of the coil structure after heat curing.

[0038] b. For the treatment of the head, the first copper bar is cushioned with a stepped oil passage to form an excessive arc without leaving a cavity, forming a stepped oil passage 3 at the ...

Embodiment 2

[0054] Such as figure 1 As shown, the manufacturing process of the anti-sudden short-circuit amorphous alloy transformer coil includes the following steps:

[0055] Step 1. Low-voltage coil winding:

[0056] a. Skeleton installation, put the 8mm thick skeleton into the winding mold, align it with the foil and interlayer insulation and fix it, and wrap a layer of full adhesive paper on the skeleton. The skeleton is a hard epoxy glass cloth tube. The interlayer insulation is fully glued paper. Full-adhesive paper can meet the insulation strength between layers of low-voltage coils and ensure the compactness and resistance to external forces of low-voltage coils. Because of its super-strong adhesive force after heating, it can ensure the integrity of the coil structure after heat curing.

[0057] b. For head treatment, the copper bar at the head is padded with stepped oil passages to form an excessive arc without leaving a cavity. The head corresponds to the opposite side of ...

Embodiment 3

[0072] Such as figure 1 As shown, the manufacturing process of the anti-sudden short-circuit amorphous alloy transformer coil includes the following steps:

[0073] Step 1. Low-voltage coil winding:

[0074] a. Skeleton installation, put a 6mm thick skeleton into the winding mold, align it with the foil and interlayer insulation and fix it, and wrap a layer of full adhesive paper on the skeleton. The skeleton is a hard epoxy glass cloth tube. The interlayer insulation is fully glued paper. Full-adhesive paper can meet the insulation strength between layers of low-voltage coils and ensure the compactness and resistance to external forces of low-voltage coils. Because of its super-strong adhesive force after heating, it can ensure the integrity of the coil structure after heat curing.

[0075] b. For head treatment, the copper bar at the head is padded with stepped oil passages to form an excessive arc without leaving a cavity. The head corresponds to the opposite side of th...

Abstract

The invention discloses a manufacturing process of an anti-sudden short circuit amorphous alloy transformer coil. The manufacturing process comprises the steps of 1 winding a low-voltage coil; 2 placing a main insulator; 3 winding a high-voltage coil; 4 brushing glue; 5 shaping; 6 curing; and 7 removing a form . The manufacturing process can effectively solve the problem that the sudden short circuit resistance of an amorphous alloy transformer is insufficient.

Description

technical field [0001] The invention relates to the technical field of oil-immersed amorphous alloy transformers, in particular to a manufacturing process of an anti-sudden short-circuit amorphous alloy transformer coil. Background technique [0002] Amorphous alloy transformer is widely used as an energy-saving and environment-friendly product because of its ultra-low no-load loss. However, due to the difficulty in cutting amorphous alloys, the cross-section of the iron core is usually rectangular, so the coil is also of rectangular structure. The electric force received by the rectangular coil is far less uniform than that of the ordinary transformer circular winding, and it is easier to deform when subjected to sudden short-circuit electric force. In addition, the straight parts on the four sides of the rectangular coil are easy to bulge and expand, and the winding is not tight. During operation, the coil is often damaged due to electrodynamic instability caused by an ex...
