Voltage self-adapting power circuit

Abstract

The invention provides a voltage self-adapting power circuit. The voltage self-adapting power circuit comprises a substation, wherein the substation is internally provided with a power transformationcavity, the power transformation cavity is internally and fixedly provided with an iron core, the iron core is internally provided with a middle rated power transformation cavity, a high rated power transformation cavity is formed under the middle rated power transformation cavity, a low rated power transformation cavity is formed under the high rated power transformation cavity, the power transformation cavity is internally and fixedly provided with a plugging-in box located at the right side of the iron core, the plugging-in box is internally and fixedly provided with vertically symmetric middle rated copper sheets, the middle rated copper sheets are internally provided with middle rated jack cavities with rightward openings, the plugging-in box is internally and fixedly provided with high rated copper sheets located under the middle rated copper sheets, and the high rated copper sheets are internally provided with high rated jack cavities with rightward openings. The voltage self-adapting power circuit has the advantages that the structure is simple, the use is convenient, the improved design is carried out for the problems of different voltages of electric appliances used by international different countries, manual adjustment can be carried out according to the voltages of the electric appliances, the electric appliances are of mechanical structures, and in the process, only a key needs to be pressed, the conversion of the voltages can be completed.

Description

technical field [0001] The invention relates to the field of changing the voltage of civil electrical appliances, in particular to a voltage self-adaptive power supply circuit. Background technique [0002] Traveling abroad is one of the ways people go on vacation at present, and more and more people choose to travel abroad, but due to different countries, the size of the civilian voltage in each country is also different, people who travel often need to go to the store to buy different transformers In order to meet the needs of travel in different countries, this method is very troublesome, and the transformer with relatively high quality is easy to spontaneously ignite and cause unnecessary losses due to its circuit components. The design of the present invention is proposed for the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a voltage adaptive power supply circuit to solve the problems raised in the background ar...
