Problems solved by technology

In the case of the same cross-sectional area of ​​the coil, the rectangular magnetic circuit consumes more silicon steel sheet material, and the magnetic energy loss is greater
Secondly, the ballast uses stamped silicon steel sheets to be vertically stacked into modules, and the modules are cut by the punched edge of the silicon steel sheets and assembled into a magnetic core body, resulting in poor consistency of the magnetic core body and poor structural stability, and the ballast works prone to electromagnetic vibration and low-frequency noise
Secondly, the magnetic core body is a zigzag structure, and its center is a hollow structure. Under the same magnetic flux, when the magnetic core body is a zigzag structure, the corresponding coil circumference is longer, more consumables, and greater energy consumption

Embodiment Construction

[0033] See figure 1 As well as figure 2 The height of the square -shaped magnetic core 8 is smaller than the height of the side wall 6 of the magnetic core.There is a magnetic gap between the corresponding upper and lower square magnetic core 8.

[0034] See figure 1 The center of the magnetic core 8 does not open the hole, which is a solid structure.

[0035] As another other embodiment (unspecified icon), Figure 1 to Figure 3 The center of the E cross -shaped magnetic core shown is a cylindrical magnetic core convex, and the vertical side wall 6 of the upper and lower E cross magnetic core 2 and 3 are arcs.The shape groove, the corresponding coil 4 is round.The above -mentioned e -cross -shaped magnetic core 2 and 3 buckle are symmetrical of the upper and lower petals.

[0036] figure 2 The iron shell is covered with the outside of the magnetic core structure, and the magnetic core and coil are tightened and shielded.

[0037] In the present invention, the production method of E...

Abstract

The invention relates to an energy and material saving magnetic ballast or transformer. The magnetic ballast or transformer comprises a magnetic core body and a coil; the magnetic core body is formed by buckling upper and lower E crossed magnetic core bodies which have systematical structures and a magnetic circuit of each magnetic core body is closed; in the upper E crossed magnetic core body or the lower E crossed magnetic core body, the central part is provided with a magnetic core body boss; the periphery corresponding to the magnetic core body boss is provided with vertical magnetic core body side walls; wire insertion grooves are formed between the magnetic core body side walls and the periphery corresponding to the magnetic core body boss; the grooves have groove bottoms; the upper ends of the grooves are provided with openings; and the coil is inserted into whole wire insertion grooves which are formed by bucking the upper and lower E crossed magnetic core bodies which have systematical structures. Compared with the conventional magnetic ballast or transformer, the energy and material saving magnetic ballast or transformer has the advantages that enamelled wires and silicon sheets are saved, electric resistance and magnetic loss are reduced, and energy consumption is reduced.

Description

Technical field [0001] The invention involves an inductive ballast or a transformer. Background technique [0002] The existing market lighting is divided into two categories: inductance and electronic.Due to the short service life and high -frequency harmonic interference, the market still adopts the inductive ballast due to the short service life and high -frequency harmonic interference.The inductive ballast is basically divided into two categories according to the magnetic core structure: E -shaped and C -shaped.C -shaped ballasts Due to the complex processing process and expensive prices, the domestic products are still used as the mainstream market products. [0003] The Chinese patent CN2724167Y revealed an inductive ballast that includes E cross -shaped magnetic cores and magnetic crickets, and its magnetic circuit is rectangular.In the same case of coil cross -sectional area, the magnetic circuit consumes more silicon steel sheets consumed by the rectangular shape and th...
