Example Embodiment

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0022] This embodiment provides an electronic transformer, which includes a magnetic core 1, a wire part 2, a wire frame 3, a magnetic core, a copper foil, a bushing, and the like. Such as figure 1 with figure 2 As shown, the wire portion 2 includes multiple stranded wires, and each stranded wire 21 is formed by twisting multiple wires; the multiple stranded wires are wound on the wire rack 3, and then installed on the magnetic Core 1 on. A plurality of wires are twisted into a strand to obtain a stranded wire. Each wire can be made of enameled wire, specifically, can be made of enameled copper wire. The electronic transformer in this embodiment is wound with multiple twisted wires, and the original single thicker wire is replaced by several thin wires twisted into a single stranded wire. Each stranded wire can be twisted together by a stranding mach...

Abstract

The invention relates to the field of electronic transformers, in particular to an electronic transformer which comprises a wire rack and a wire part. The wire part comprises a plurality of strands of twisted wires, each strand of wires is formed by a plurality of wires in a twisted mode, and the strands of twisted wires are wound on the wire rack. According to the electronic transformer, the wires are twisted into a strand and then are wound together to form the twisted wires, so that the effective surface area of unit cross-sectional area wires is increased, limited conductor surfaces are utilized to the largest extent, and the skin effect is greatly lowered. By means of the electronic transformer, the utilization efficiency under the same wire diameter is increased, the heat generating amount of the electronic transformer is lowered, the service life is prolonged, meanwhile, the interference effect of a single copper wire in the working process is lowered, and the electronic transformer can normally work more stably.

Description

technical field [0001] The invention relates to the field of electronic transformers, in particular to an electronic transformer. Background technique [0002] An electronic transformer is an unregulated switching power supply, which is actually an inverter. First rectify the alternating current into direct current. Then use electronic components to form a high-frequency oscillator to convert direct current into high-frequency alternating current. Output the required voltage through the switching transformer and then rectify it twice for use by electrical appliances. Switching power supply has the advantages of small size, light weight, low price, etc. Electronic transformers are widely used in traditional lighting fixtures, such as fluorescent lamps, table lamps, energy-saving lamps, advertising lights, etc. Almost all of them can use electronic transformers, and after using electronic transformers, The starter can be omitted. In LED (light-emitting diode) lighting, most ...
