Abstract
The utility model discloses a lead wire type toroidal transformer relates to transformer technical field, including troidal core, winding, PVC lead wire, the troidal core both sides are provided with the inner groovy, and the inner groovy embeds the fin, and the winding is the part of free accommodation troidal core except that the inner groovy uniformly, and the PVC lead wire comes out from the troidal core amplification, and the troidal core is made by the cold rolled silicon steel piece. The utility model provides a lead wire type toroidal transformer heat dispersion is good to possess multiple mounting means, the high -speed joint of being convenient for.
Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of lead type toroidal transformer.
Background technology
In existing transformer core, many all air gap being set, open air gap mainly in order to reduce remanent magnetism when iron core works under the state of dissymmetrical magnetic field, but the inductance coefficent of the larger iron core of air gap being less, just need the more coil of coiling to reach certain inductance value, relevant copper loss also increases.Visible not all iron core all should offer air gap, should carry out selection arrange or do not arrange air gap according to the functional characteristic of transformer.In addition, the heat dispersion of transformer concerns operating efficiency and the useful life of transformer.
Summary of the invention
The purpose of this utility model is to provide a kind of lead type toroidal transformer, excellent heat dissipation performance, possesses multiple mounting modes, is convenient to quick connection, and low-loss, low noise.
In order to achieve the above object, the utility model adopts following technical scheme:
Lead type toroidal transformer, comprise annular core, winding, PVC lead-in wire, annular core both sides are provided with inner groovy, inner groovy internal set heat radiation fin, winding encases the part of annular core except inner groovy equably, PVC lead-in wire extends out from annular core, and annular core is made by cold-reduced silicon sheet.Annular core radiation field is lower, efficiency is higher, when size and weight reduce by half, can meet the requirements of capacity; The fin arranged improves the heat dispersion of transformer; Winding evenly wraps on annular core tightly, effectively reduce transformer run time magnetostriction cause " drone " sound, reduce noise; Annular core permeability made by cold-reduced silicon sheet is high, and easily magnetize, energy loss is little, contributes to the operating efficiency improving transformer; PVC lead-in wire setting both can be used for scolding tin connect, again can as required splicing ear, be convenient to quick connection; Due to the setting of the core structure of annular and PVC lead-in wire, the utility model has multiple mounting modes, comprises mesopore encapsulation type, sunk type, horizontal, vertical, bridge-type etc. available.
One as the utility model lead type toroidal transformer is improved, and annular core does not arrange air gap.Then annular core keeps larger inductance coefficent, reduces copper loss and no-load loss, in being applicable to, low-frequency transformer, especially when standby, is conducive to energy savings; The noise that during effective minimizing iron core induction, vibrations produce.
The beneficial effects of the utility model are, fin improves the heat dispersion of transformer, are conducive to the useful life extending transformer; Winding hard-pressed bale annular core, annular core do not arrange air gap, effectively reduce transformer run time magnetostriction cause " drone " sound, reduce iron core induction time vibrations produce noise; Annular core is made by cold-reduced silicon sheet, easily magnetizes, and energy loss is little, contributes to the operating efficiency improving transformer; The setting of the core structure of annular and PVC lead-in wire, makes transformer have multiple mounting modes, is convenient to quick connection; Do not arrange the annular core of air gap, radiation field is lower, efficiency is higher, and loss is low, keeps larger inductance coefficent, in being applicable to, low-frequency transformer, especially when standby, is conducive to energy savings.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model lead type toroidal transformer;
Fig. 2 is the vertical view of the utility model lead type toroidal transformer.
Reference numeral: annular core 1, winding 2, PVC goes between 3, inner groovy 4, fin 5.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As depicted in figs. 1 and 2, lead type toroidal transformer, comprise annular core 1, winding 2 and PVC lead-in wire 3, annular core 1 both sides are provided with inner groovy 4, inner groovy 4 internal set heat radiation fin 5, winding 2 wraps on annular core 1 equably, and PVC lead-in wire 3 extends out from annular core 1, and annular core 1 is made by cold-reduced silicon sheet.Wherein, annular core 1 does not arrange air gap.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong to this practicality newly
Within the protection range of type claim.
