Background technology
The iron core great majority of the electromagnetic potential transformer used in current electric power system adopt laminated structure or C iron-core structure, and a winding and secondary winding around on insulating cylinder, insulating cylinder is enclosed within outside open core post.Because the iron core of voltage transformer is opening, the course of processing easily produces gap, usually there will be the situation that excitation property is inconsistent; product does not mate when using; and leakage field causes greatly core volume large, stacked or C iron-core processing technology complexity, adds manufacturing cost and difficulty in addition.
Summary of the invention
Problem to be solved in the utility model is: for prior art Problems existing, provides a kind of band not cut the electromagnetic potential transformer of continuous reeling iron core, improves the electromagnetic performance of product, solves the problems such as conforming product rate is low, processing technology is complicated.
In order to solve the problems of the technologies described above, the utility model provides the electromagnetic potential transformer that a kind of band does not cut continuous reeling iron core, comprise the iron core not cutting continuous reeling, a winding, primary connection terminal, insulating cylinder, secondary winding, secondary wiring terminals and base plate, a described winding uniform winding is outside insulating cylinder, primary connection terminal is arranged on the top of a described winding, described secondary winding be wrapped in unshakable in one's determination go up and overlap be enclosed in insulating cylinder bottom inside, described bottom unshakable in one's determination is provided with secondary wiring terminals, a described winding and secondary winding are fixed on base plate after insulated enclosure.
In technique scheme, described iron core is the iron core not cutting continuous reeling, uses the iron core not cutting continuous reeling to replace traditional C iron-core, can when ensure not leakage field, effectively reduce core volume.
In technique scheme, a described winding and secondary winding are fixed on base plate after insulated enclosure.
In technique scheme, described secondary winding is on iron core and cover is enclosed in insulating cylinder bottom inside; A winding is outside insulating cylinder, and secondary winding is on iron core and be positioned at inside insulating cylinder, and this kind of canoe effectively improves the electromagnetic performance of voltage transformer, reduces leakage field phenomenon.
In technique scheme, filling epoxy resin between described iron core and shell.
In technique scheme, described primary connection terminal and secondary wiring terminals form external coupling part.
The beneficial effects of the utility model are: this electromagnetic potential transformer adopts the iron core not cutting continuous reeling, a winding is outside insulating cylinder, secondary winding is on iron core and be positioned at inside insulating cylinder, effectively improve the electromagnetic performance of voltage transformer, simultaneously and decrease the volume of product; This product adopts the iron core not cutting continuous reeling in addition, and leakage field is little, and Product Precision is high.
