Frameless type electric reactor convenient to wind wire

Abstract

The invention discloses a frameless type electric reactor convenient to wind wire. The frameless type electric reactor comprises coils, an iron core, wrapped wire struts and wrapped wire positioning modules; the wrapped wire struts are uniformly distributed on the side surface of the iron core; the coils are wound on the outer wall of the wrapped wire struts; the wrapped wire positioning modules comprise positioning pieces and snap joint pieces; each positioning piece is provided by the a wire head groove and a wire tail groove; and the wire heads and the wire tails of the coils are separatelyplaced into the wire head grooves and the wire tail grooves and locked by the snap joint pieces. According to the frameless type electric reactor convenient to wind wire provided by the invention, the frame structure in the conventional electric reactor is removed, the coils are directly wound on the wrapped wire struts on the outer side of the iron core, so that gaps are reserved between the coils and the iron core so as to form heat dissipation air flues, the effective heat dissipation area of the coils is increased, and the thermal loads of the surfaces of the coils are reduced; the wrapped wire positioning module, so that the wire heads and the wire tails do not need to be manually bound and fixed during the winding process of the coil, the outgoing positions of the wire heads and thewire tails can be accurately controlled in product production, the consistency of the products is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of reactors, in particular to a frameless reactor which is convenient for winding. Background technique [0002] In the current reactor structure, the coil winding is usually wound on the skeleton, and then the coil winding is placed outside the iron core for product assembly. This structure not only has no air duct inside the coil, but also reduces the inherent heat dissipation area of ​​the coil itself. , Increase the surface heat load, which is not conducive to the high temperature rise of the coil heat dissipation. In order to limit the high temperature rise, the cross-sectional area of ​​the wire can only be increased to reduce the temperature rise, which increases the objective disadvantages such as the cost of the wire material.

Problems solved by technology

[0002] In the current reactor structure, the coil winding is usually wound on the skeleton, and then the coil winding is placed outside the iron core for product assembly. This structure not only has no air duct inside the coil, but also reduces the inherent heat dissipation area of ​​the coil itself. , increase the surface heat load, which is not conducive to the high temperature rise of the coil heat dissipation. In order to limit the high temperature rise, we can only increase the cross-sectional area of ​​the wire to reduce the temperature rise, thus increasing the cost of the wire material and other objective shortcomings

[0003] In addition, in the coil winding process of traditional reactors in the past, before winding, the wire end is first clipped into the outlet slot of the frame, wrapped and bound with glass fiber tape, and then the wire end is fixed at the end of the frame or in the wire slot to hold the product. The consistency of the coil, and then start winding, when the coil is finished, the end of the wire is wrapped and fixed with glass fiber tape to complete the winding work. In this way, during the coil winding process, due to the binding and fixing It takes too long. In addition, in the mass production of large-scale products, it is difficult to accurately manually control the outlet position of the thread head and thread end, resulting in poor product consistency. In addition, the cycle is too long during the entire coil processing process, resulting in reduced work efficiency and other objective shortcomings.
