Electronic transformer wound by adopting segmented stacking method

Abstract

The invention provides an electronic transformer wound by adopting a segmented stacking method. The winding method comprises the following steps of: equally dividing the winding groove of a frameworkinto four sections by using parting strips, wherein one side section is vacant; equally dividing a primary P winding into four sections without being disconnected; winding the primary P winding from the vacant side section to a first flat section, stripping the parting strips by sections, performing winding by sections, sequentially wrapping an insulating tape, a copper sheet and an insulating tape outside the primary P winding, wrapping an insulating tape outside a winding secondary S winding, wrapping an insulating tape outside a winding Aux winding, and finishing coil winding; performing tin stamping, circle number measuring and magnetic core assembling; and performing intermediate performance detection, paint dipping, drying, foot correction, secondary tin ironing, labeling, reinspection and delivery inspection. The winding effect is good, the process operation is simple, the parting strips are repeatedly used, the layers of the winding are arranged in order, the sections are separated uniformly, the effect of sectional voltage division is achieved, the performance of the product is improved, the high-frequency leakage inductance is reduced, and the distributed capacitance is reduced.

Description

technical field [0001] The invention relates to a transformer, in particular to an electronic transformer wound by a segmented stacking method. Background technique [0002] There are many winding methods for transformers, and different winding methods can meet different performance requirements, but some winding methods are relatively difficult to realize, such as the segmented stacking method. A common winding method, the purpose is to reduce the interlayer withstand voltage and improve the performance of insulation and partial discharge, and the main purpose of the segmental winding of the electronic transformer is to reduce the high-frequency leakage inductance and reduce the distributed capacitance, which are the same The point is to improve the performance of the product. The difference is that the winding space of the power transformer is large and easy to operate, while the winding space of the electronic transformer is relatively much smaller. In this small space, w...
