Abstract

The utility model relates to an ultra-thin UPS power supply and pertains to a UPS power supply for computer. A power transformer of the ultra-thin UPS power supply adopts ring core wrapped with strip copper foil, high and low voltage winding wrap the strip copper foil and is arranged inside a pure iron shielding box, two layers of silicon steel sheets are laminated between positions above and below the winding and the shielding box, the pure iron shielding box is wrapped with a copper shielding box. As the power transformer adopting the structure, the copper foil reduces magnetic leakage along a circle direction, two layers of silicon steel sheets, the pure iron shielding box and the outer copper shielding box further shield interference of electromagnetic radiation caused by magnetic leakage on all directions, so that the power transform almost does not leak any electromagnetic wave, thus guaranteeing that the ultra-thin UPS power supply can be directly arranged below a display for use.

Description

Ultrathin ups power

Technical field: the utility model relates to a kind of ultrathin ups power, belongs to the computer uninterrupted power supply.

Background technology: for preventing sudden power, cause the computer obliterated data, computer generally all has ups power, but because ups power adopts high-frequency inversion, can produce the high frequency width of cloth and penetrate, computer and peripheral equipment had High-frequency Interference, influence the operate as normal of main frame and display, so the position that ups power is put needs all with a certain distance from main frame and display, inconvenience, take up space again, interference also generates electromagnetic waves.

Summary of the invention: the purpose of this utility model is to provide a kind of ultra-thin super ups power for overcoming the deficiencies in the prior art, and this ultrathin type ups power has very little electromagnetism wave amplitude and penetrates and can place under the display and use.

For reaching the purpose of this utility model, the technical solution of taking is: ultrathin ups power comprises rectifier, inverter, inverter trigger control circuit, controlling circuit of voltage regulation, storage battery, power transformer and shell, it is characterized in that: power transformer adopts annular core, annular core is surrounded by banded Copper Foil outward, the high-low pressure winding is outside banded Copper Foil and place the pure iron shielding box, winding accompanies two-layer silicon steel sheet up and down and between the pure iron shielding box, and the pure iron shielding box also is surrounded by copper shielding box outward.

Adopted the power transformer of said structure in the ups power, Copper Foil has reduced leakage field along the circumferential direction, two-layer silicon steel sheet and pure iron shielding box and outer copper shielding box have further shielded the electromagnetic radiation interference that all directions leakage flux forms, make the power transformer magnetic wave that almost do not leak electricity, thereby having guaranteed that ultrathin ups power can directly place under the display uses.

The utility model is described in further detail and provide embodiment simultaneously below in conjunction with accompanying drawing.
