The utility model relates to an embedded transformer, including elementary pin, primary winding, secondary pin, secondary, iron core, insulating part, elementary hypoplastron, elementary upper plate, secondary hypoplastron, secondary upper plate, elementary pin, secondary pin are the L type. The primary winding external diameter is less than elementary upper plate. The secondary external diameter is less than secondary upper plate. The utility model discloses an in being embedded into secondary with primary winding, moreover, elementary pin, secondary pin are the L type, can greatly reduce embedded transformer height, adopt embedded transformer owing to adopt the embedded type design, have the characteristics that coupling nature is good, small, outside nested primary winding and secondary were located to the iron core cover moreover, in the transformer use, the skeleton was difficult for expansion deformation, can reduce the interior vortex of iron and [magnetic] hysteresis loss.
Description
Technical field
The utility model relates to electrical equipment, specifically embedded transformer.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: power transformer and special transformer (electric furnace change, rectification change, power frequency testing transformer, voltage regulator, mining change, audio frequency transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, instrument transformer etc.).
Transformer is generally made up of iron core (or magnetic core) and coil, and coil has two or more winding, and wherein connect the winding of power supply primary coil, remaining winding is secondary coil.Effect unshakable in one's determination is the magnetic coupling between reinforcement two coils.In order to reduce eddy current and magnetic hysteresis loss in iron, iron core is formed by the silicon steel plate stacking of painting; Do not have the contact of electricity between two coils, coil is coiled into by insulated copper wire (or aluminum steel).A coil connects AC power and is called primary coil (or primary coil), and another coil connects electrical appliance and is called secondary coil (or secondary coil).At present transformer ubiquity coupling difference on the market and the shortcoming such as volume is large, in prior art, armature winding, secondary winding wound are on same skeleton, iron core (two sections of merging) is sheathed on outside skeleton, in transformer use procedure, skeleton is heated easy dilatancy, and the iron core being sheathed on its outside, because of framework deformation, causes it to connect deleterious, the magnetic coupling between two coils can be reduced, increase eddy current and magnetic hysteresis loss in iron simultaneously.
Summary of the invention
The utility model, just for above technical problem, provides that a kind of coupling is good, volume is little, and iron core sleeve is located at the embedded transformer outside nested armature winding, secondary winding.
The utility model is achieved through the following technical solutions:
Embedded transformer, comprise primary pins, armature winding, secondary pins, secondary winding, iron core, insulating part, elementary lower plate, elementary upper plate, secondary lower plate, secondary upper plate, it is characterized in that being provided with armature winding between elementary upper plate and elementary lower plate, secondary winding is provided with between secondary upper plate and secondary lower plate, secondary lower intralamellar part is provided with sunk part, elementary upper plate is embedded into the inner recess place of secondary lower plate together with armature winding, iron core sleeve is located at outside nested armature winding and secondary winding, and insulating part is sheathed on outside iron core.Primary pins, secondary pins are L-type.Armature winding external diameter is less than elementary upper plate.Secondary winding external diameter is less than secondary upper plate.
The utility model is by being embedded in secondary winding by armature winding, and, primary pins, secondary pins are L-type, greatly can reduce embedded transformer height described in the utility model, adopt embedded transformer described in the utility model owing to adopting embedded design, have the advantages that coupling is good, volume is little, and iron core sleeve is located at outside nested armature winding and secondary winding, in transformer use procedure, skeleton is dilatancy not easily, can reduce eddy current and magnetic hysteresis loss in iron.
The utility model structure is simple, with low cost, easy to use.
