Embodiment Construction

[0013] A method for winding an amorphous alloy transformer coil, comprising the following steps:

[0014] First of all, wind the low-voltage coil, fix the starting lead row with auxiliary tools such as this article, and clamp it in the notch of the insulating cylinder. When winding the beginning, make a circle without tension. After the beginning is completed, remove the auxiliary tool to adjust the size so that It meets the drawing requirements.

[0015] Secondly, the low-voltage coil is wound with tension, and the surface of the copper foil is tapped while winding. When tapping the copper foil, pay attention to uniform force, and tap the entire surface, not just a certain point, which will cause a short circuit of the coil. As far as possible to ensure the size of the interphase part of the coil. When winding to a turn where the stays are placed, place the stays between the layer insulation and the copper foil. The distance between the stays is as required by the drawing, a...

Abstract

The invention discloses a production method for windings of an amorphous alloy transformer, which comprises the following steps: making a low-voltage winding: fixing start leads in rows with an assistant tool and locking inside a rabbet of an insulating cylinder, winding the start leads without tension, and removing the assistant tool after the start lead winding is completed and regulating the size; making the low-voltage winding under tension: winding while knocking the surface of a copper foil, compressing the low-voltage winding to the specified size after the low-voltage die is removed, drying and painting; winding a high-voltage winding on the low-voltage winding to obtain an amorphous alloy transformer winding. Based on the combination of low-voltage and high-voltage windings, the invention can eliminate the influence of positive deviation of the low-voltage winding and ensure the insulation distance between the low-voltage and high-voltage windings.

Description

technical field [0001] The invention relates to a method for winding an amorphous alloy transformer coil. Background technique [0002] The coil structure of most of the existing transformer products adopts the traditional multi-layer cylindrical coil, and the structure of high and low voltage separate winding. The amorphous alloy transformer is a rectangular coil, which cannot be formed naturally like a cylindrical coil during the winding process. To ensure the long-term safety and reliability of the amorphous alloy transformer, the insulation distance between the high and low voltage coils must be guaranteed. Since the high and low voltage coils are wound separately, it is difficult to ensure the insulation distance between the high and low voltage coils during assembly, resulting in excessive interlayer voltage and large partial discharge. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the present invention is to provide...
