Abstract
The utility model relates to a fully enclosed voltage mutual inductor which comprises a primary winding, a secondary winding, an iron core, a resin insulation layer and a bottom plate, wherein the iron core is located in the resin insulation layer, the bottom plate comprises a first iron bottom plate and a second iron bottom plate, both sides of the bottom of the resin insulation layer are connected with the first iron bottom plate and the second iron bottom plate, the center of the bottom of the resin insulation layer is located between the first iron bottom plate and the second iron bottom plate, the iron core is completely located in the resin insulation layer, and a fully enclosed structure is formed. The first iron bottom plate and the second iron bottom plate are made of A3 steel, a die needs not to be manufactured, machining time is short, mechanical strength is good, weight is light and the fully enclosed voltage mutual inductor is easy to move. When a client needs to change size of the bottom plate or installation size due to installation requirements, the fully enclosed voltage mutual inductor is easy to manufacture, and various requirements of the client can be met. Due to that the iron core on the bottom of the resin insulation layer is completely poured in resin, the fully enclosed structure is formed, insulation resistance is enabled to be improved, and performance of the voltage mutual inductor is improved.
Description
Technical field
The utility model belongs to the voltage transformer technical field, particularly relates to a kind of totally-enclosed voltage transformer.
Background technology
The voltage transformer of semi-open structure, mounting base are the cast aluminium base plate.Cover with the part iron core that exposes with the secondary line of this cast aluminium base plate with product, because the sub-fraction iron core is exposed to outside resin bed, may causes base plate interior to get damp because of the change of environment thus, thereby cause the insulation resistance of product low.And this cast aluminium base plate need use Mold Making, and the time is longer, and base plate size can not be changed.After long-time the use, mould is easily aging, and the expense of making mould is very high.
After if the client changes installation dimension, former voltage transformer will can not meet the requirement of new installation dimension, can cause thus the replacing of product, thereby increase unnecessary economic input and trouble is installed.
Summary of the invention
The utility model provides a kind of simple in structure, easy for installation for solving the technical problem that exists in known technology, can satisfy the totally-enclosed voltage transformer of multiple demand and raising insulation resistance.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of totally-enclosed voltage transformer, comprise first and second winding, iron core, resin insulating barrier and base plate, iron core is positioned at resin insulating barrier, described base plate comprises the first iron bottom plate and the second iron bottom plate, described resin insulating barrier two bottom sides and the first iron bottom plate be connected iron bottom plate and be connected, the bottom centre of described resin insulating barrier is between the first iron bottom plate and the second iron bottom plate, described iron core all is positioned at resin insulating barrier, forms full-closed structure.
The material of described the first iron bottom plate and the second iron bottom plate is A3 steel matter.
Advantage and the good effect that the utlity model has are: the utility model uses A3 steel matter to make the first iron bottom plate and the second iron bottom plate, does not need to make mould, and process time is short, and mechanical strength is better, and is lightweight, easily moves.The client easily makes because install when needing change base plate size or installation dimension, can satisfy client's multiple demand.Because the iron core of insulative base all is cast in resin, form full-closed structure, make insulation resistance be improved, improved the performance of voltage transformer.
