Embodiment

[0015] Embodiment: the method for transformer iron core binding, comprises the following steps:

[0016] (1) First cut the raw material iron chips, place the clamps and auxiliary clamping devices, then stack the iron chips in sequence, clamp the iron core column, turn the iron core column up, and keep the iron core on a plane;

[0017] (2) Use a tightener to tighten the iron core column at the gap of the auxiliary clamping device to ensure that the iron core column remains straight and not skewed when the auxiliary clamping device is removed;

[0018] (3) Remove the above-mentioned auxiliary clamping device of the iron core column, and select B-grade heat-resistant Tenax polyester tape according to the technical requirements of the drawing, 19mm×1.27mm for products above 3150KVA, resistance strength: 11120N; products below 3150KVA Use Tenax polyester belt specification 12mm×0.71mm, resistive strength: 3560N; The tightening force of the grease belt specification 12mm×0.71mm is...

Abstract

The invention discloses a method for binding a transformer iron core, which includes: firstly, cutting iron core chips which serve as raw materials, then sequentially stacking the iron core chips, clamping an iron core column and overturning and rising the iron core column; secondly, removing a center column clamping device and binding a Tenax polyester belt; thirdly, binding the other two columns of the transformer with Tenax polyester belts and then suiting the device body. According to the binding method for transformer iron core, without curing, the iron core binding has the advantages of having a short working time, high binding efficiency, big binding force of the polyester belt, high strength of extension, low cost and good economic benefits, besides, a large amount of working time is saved, the manufacturing cycle of the iron core is shortened, the operation is convenient and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for binding transformer iron cores, belonging to the technical field of transformers. Background technique [0002] At present, the general technological process of transformer core production is: cutting of iron chips → stacking of iron cores → painting and curing of iron core columns → erecting of iron cores → binding of iron cores with adhesive tape → body suiting. [0003] The disadvantages of this process are: the iron core column needs to be painted and cured, and the non-weft glass adhesive tape is bound and dried, and the curing time is 24 hours at room temperature or heated and dried. Increased cost, complicated operation and low production efficiency. Contents of the invention [0004] Aiming at the deficiencies and defects of the prior art, the invention provides a method for binding transformer iron cores. [0005] In order to achieve the above object, the present invention adopts the following technica...
