Abstract
A dynamic motor salient-pole winding interelectrode support device is provided, interelectrode space between each two adjacent excitation windings is filled with an insulating filling which takes an insulator with a certain pressure resistant performance as a matrix and then the insulator is dipped with insulating varnish or insulating cement and is dried to form the insulating filling, which is prearranged into an integral section or a subsection to fill into the remaining interelectrode space, the axial length of the filling in the interelectrode space is 70-80 percent of the effective length of an iron core, a cover plate for pressing the insulating filling is made of non-magnetic plate, two ends are embedded in grooves which are pre-arranged at the two sides of adjacent pole shoes. The invention has the advantages that sectional area of the excitation winding is enlarged, friction loss of ventilation is reduced, and ventilation noise is lowered.
Description
Technical field
The present invention relates to a kind of support device between poles of power motor salient pole windings.
Background technology
The interpolar support device of power motor salient pole winding commonly used, shared interelectrode space volume is bigger, and effective rate of utilization is low, and ventilation frictional dissipation and ventilation noise are bigger.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of support device between poles of power motor salient pole windings is provided.
Technical scheme of the present invention is: a kind of support device between poles of power motor salient pole windings, it is characterized in that: be filled with insulating packing in the interelectrode space between per two adjacent field windings of water-cooled salient pole synchronous electric machine, this filler is a matrix with the insulator with certain withstand voltage properties, soaked to dry behind insulating varnish or the insulating cement and made, insulating packing is made whole section or segmentation in advance and is inserted the interpolar remaining space, the axial length that filler is filled in interelectrode space is the 70-80% of iron core effective length, the cover plate that is used to push down insulating packing is made with nonmagnetic sheet material, and two ends embed in the groove of holding successfully in advance adjacent pole shoe both sides.
The present invention has the following advantages: increase the field winding sectional area, reduce the ventilation frictional dissipation, reduce the ventilation noise.
