Description
Technical field
The present invention relates to inductive type ballast or transformer.
Background technology
The existing market illumination is divided into two big types with ballast: inductance type and electronic type.Electronic ballast is because useful life is short and problem such as high-frequency harmonic interference, thus market adopt mostly remain inductance type ballast.Inductance type ballast is divided into two types basically according to the magnetic core array structure: E font and C font.C font ballast is because problem such as processing technology complicacy and price be more expensive, and at present domestic is the mainstream product in the market with E font ballast still.
The Chinese patent CN 102360770A " Inductive ballast of energy-saving material-saving or transformer " of the applicant's application; It comprises magnetic core array and coil; Said magnetic core array is fastened by the E cross magnetic core array of two valve structures symmetry up and down and constitutes, and the magnetic circuit of said magnetic core array is closed; Being configured to of said epivalve or hypovalve E cross magnetic core array: the center has the magnetic core array boss; The periphery of corresponding magnetic core array boss is provided with vertical magnetic core array sidewall respectively; Constitute the rule groove respectively between said magnetic core array sidewall and the said corresponding magnetic core array boss periphery; Said groove has bottom land, and the upper end of groove is uncovered, and said coil embeds in the whole rule groove that the E cross magnetic core array fastening of two valve structures symmetry constitutes up and down; The height of said magnetic core array boss is less than the height of said magnetic core array sidewall, when the E cross magnetic core array of two valve structures symmetry up and down fastens when constituting the closed magnetic core array of said magnetic circuit, correspondingly leaves magnetic gap between the magnetic core array boss up and down,
The Inductive ballast of making according to said structure is suitable for requirement magnetic leakage circlet border and uses through test.The chance of a chance; The applicant states in the test of Inductive ballast on the implementation, and the height of above-mentioned magnetic core array boss has been made the height greater than said magnetic core array sidewall, when the E cross magnetic core array of two valve structures symmetry fastens the magnetic core array that constitutes said magnetic circuit closure up and down; Leave magnetic gap between the magnetic core array sidewall about corresponding; Through test, find that the magnetic resistance of magnetic core array reduces obviously, the inductance value of Inductive ballast is significantly improved; Under the situation of same electrical sensibility reciprocal, further energy-saving material-saving.
Summary of the invention
The applicant provides a kind of Inductive ballast or transformer of further saving metal material and energy on the basis of above-mentioned test, it is with respect to Chinese patent CN102360770A, and the magnetic resistance of magnetic core array obviously reduces, and can further improve the effect of energy-saving material-saving.
Technical scheme of the present invention is following:
The Inductive ballast of energy-saving material-saving or transformer comprise magnetic core array and coil, it is characterized in that: said magnetic core array is fastened by the E cross magnetic core array of two valve structures symmetry up and down and constitutes, and the magnetic circuit of said magnetic core array is closed; The structure of said epivalve or hypovalve E cross magnetic core array is following: the center has the magnetic core array boss; The periphery of corresponding magnetic core array boss is provided with vertical magnetic core array sidewall respectively; Constitute the rule groove respectively between said magnetic core array sidewall and the said corresponding magnetic core array boss periphery; Said groove has bottom land, and the upper end of groove is uncovered, and said coil embeds in the whole rule groove that the E cross magnetic core array fastening of two valve structures symmetry constitutes up and down; The height of said magnetic core array boss is greater than the height of said magnetic core array sidewall; When the E cross magnetic core array of two valve structures symmetry fastens the magnetic core array that constitutes said magnetic circuit closure up and down; Closely knit connection between the corresponding up and down magnetic core array boss correspondingly leaves magnetic gap between the magnetic core array sidewall up and down.
Further technical scheme is:
The leaving certain gaps uncovered by the economic plan between the vertical magnetic core array sidewall of said all directions of said whole rule groove;
Said magnetic core array boss is a solid construction;
Said epivalve or hypovalve E cross magnetic core array center have square magnetic core array boss, and it is square magnetic circuit that the E cross magnetic core array of the said symmetry of two valve structures up and down fastens the closed magnetic circuit that constitutes;
Technique effect of the present invention is: in magnetic loop, the magnetic gap place is maximum to the resistance of the magnetic line of force, and promptly the magnetic gap place has maximum magnetic resistance.The magnetic gap area is big more, and the magnetic resistance of Inductive ballast or transformer is just big more, and corresponding inductance is more little.In design of the present invention, pass through the cross-sectional area sum of the magnetic flux area (being the area of center magnetic core body projection section) of coil greater than four sidewalls of magnetic core array.Therefore work as the height of the height of center magnetic core array projection section greater than said magnetic core array sidewall, magnetic gap is positioned at center magnetic core body sidewall part, and corresponding magnetic resistance reduces, and inductance value increases.See Fig. 1-C, the area of establishing center magnetic core body projection section is A, and the cross-sectional area sum of four sidewalls of magnetic core array is B, A＞B, and then the increase percentage of inductance value is:
〔（Ａ－Ｂ）／Ｂ〕×100%＝〔（Ａ／Ｂ）－1〕×100%
Visible by following formula, under the inductance value of the present invention situation identical, can reduce the number of turns of coil with the Chinese patent CN102360770A inductance value of the applicant's application, reach the technique effect of further saving metal material and energy.
