Description

A kind of ballast core structure

Technical field

The utility model relates to field transformer, particularly relates to a kind of core structure of ballast.

Background technology

Inductive ballast is an iron inductance coil with choking effect, when Inductive ballast is used for fluorescent lamp, if the electric current in the Inductive ballast coil changes, then can in coil, cause the variation of magnetic flux, and the magnetic flux that changes will produce corresponding induced electromotive force, the direction of induced electromotive force is opposite with sense of current, thereby can hinder curent change, plays the effect of restriction and stabling current.

Used the core structure in Inductive ballast mostly to be square or circular in the past, eddy current loss and overheated etc. situation easily appear in square core structure after long-term the use, and the common volume of the Inductive ballast of circular magnetic core is larger, need to take larger space, simultaneously, can not carry out pre-coiling frame at core structure in the production process of this type of Inductive ballast, its production cycle is also relatively long.

The utility model content

For addressing the above problem, the utility model provides a kind of ballast core structure that carries out the pre-coiling of coil.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of ballast core structure comprises that each other head and the tail docking forms at least two core assemblies of " 0 " shape, is provided with spacer between two core assemblies of head and the tail docking, all is arranged with the coil groups frame on each core assembly.

Be further used as the improvement of technical solutions of the utility model, core structure is that the core assembly of two " J " shapes is spliced into.

Be further used as the improvement of technical solutions of the utility model, core structure is that the core assembly of two " U " shapes is spliced into.

Be further used as the improvement of technical solutions of the utility model, two mutually between the core assemblies of docking and spacer by being welded and fixed.

Be further used as the improvement of technical solutions of the utility model, by each core assembly to being connected into " 0 " the shape magnetic core ties up outward and is provided with fixed band.

Be further used as the improvement of technical solutions of the utility model, " 0 " shape magnetic core is tied up outward and is provided with two cross one another fixed bands.

Be further used as the improvement of technical solutions of the utility model, core assembly comprises the some blocks of silicon steel sheets that overlap each other.

The beneficial effects of the utility model: the core structure of this ballast docks the core structure that forms " 0 " shape from beginning to end by at least two core assemblies, on each core assembly to the core structure that is connected into " 0 " shape, owing to having the effect of straight line, can on core assembly, bind in advance the coil groups frame, thereby make things convenient for the making of core structure, save Production Time and the cost of manufacture of core structure.

Embodiment

With reference to Fig. 1～Fig. 6, the utility model is a kind of ballast core structure, comprises that each other head and the tail docking forms at least two core assemblies 1 of " 0 " shape, and 1 of two core assembly of head and the tail docking are provided with spacer 2, all are arranged with coil groups frame 3 on each core assembly 1.

The core structure of this ballast docks the core structure that forms " 0 " shape from beginning to end by at least two core assemblies, on each core assembly to the core structure that is connected into " 0 " shape, owing to having the effect of straight line, can on core assembly, bind in advance the coil groups frame, thereby make things convenient for the making of core structure, save Production Time and the cost of manufacture of core structure.

As the utility model preferred embodiment, core structure is that the core assembly 1 of two " J " shapes is spliced into.

As the utility model preferred embodiment, core structure is that the core assembly 1 of two " U " shapes is spliced into.

On the core assembly 1 of " J " shape or " U " shape the straight line structure is arranged all, on the core assembly 1 of " J " shape or " U " shape, can tie up very easily and establish coil groups frame 3, in order in the manufacturing process of core structure, directly splice tying up the core assembly 1 that is provided with coil groups frame 3, and need not to finish in splicing the binding of laggard row coil groups frame 3, can make things convenient for thus the making of core structure, save Production Time.

As the utility model preferred embodiment, two mutually 2 of the core assemblies 1 of docking and spacers by being welded and fixed.

As the utility model preferred embodiment, " 0 " the shape magnetic core that is connected into by 1 pair of each core assembly is tied up outward and is provided with fixed band 4.

As the utility model preferred embodiment, " 0 " shape magnetic core is tied up outward and is provided with two cross one another fixed bands 4.

The core structure that splicing is finished can be welded and fixed at the core assembly 1 of head and the tail docking and the joint of spacer 2, outside the core structure that splicing is finished, bind simultaneously fixed band 4, the core structure that splicing is finished is further bound, strengthened its integrally-built fastness.

As the utility model preferred embodiment, core assembly 1 comprises the some blocks of silicon steel sheets that overlap each other 11.

Can consist of by the core assembly 1 of greater number the core structure of " 0 " shape, the core assembly 1 that consists of core structure is to select the silicon steel sheet 11 of the low iron loss orientation of high magnetic flux to form around folded, silicon steel sheet 11 carries out vacuum annealing under hot environment processes, simultaneously, adopt vacuum paint dipping or epoxy resin to soak into oven dry.

Needs in response to different service conditions, seven bag metal wire can be first on the group frame, coil groups frame 3 can form for one or more groups coil, lead-in wire also can increase and decrease accordingly according to the quantity of pacifying coil groups, purpose is that capable of regulating power caters to the requirement of different scene light efficiency, help the purpose that reaches energy-efficient and the consume that can lower light source.

This class formation can effectively improve eddy current loss and the heat dissipation problem of the Inductive ballast silicon steel sheet of traditional square, improves simultaneously effectively that the circular Inductive ballast of tradition takes up room greatly, the defective of time production cycle length etc.The volume of this core structure is little, can effectively improve spillage of material, reduces production costs simultaneously, and enhances productivity.This core structure is a kind of desirable energy-saving ballast, and its structural safety is reliable, has possessed also that volume is little, lightweight, temperature rise is low, the characteristics such as dynamically wide, noise is little, can change to regulate different light efficiencies by the use scenes light and shade and reach energy-efficient purpose.

Certainly, the invention is not limited to above-mentioned execution mode, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
