Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 The safety transformer shown is used to convert the three-phase AC380V power supply into a stable AC220V, and is not affected by the interference of the AC380V power supply. The safety transformer includes five terminals, and pin 1 and pin 2 are connected to three For any two phases of AC380V, pin 3 and pin 4 are voltage output terminals, and pin 5 is grounded.

[0014] The safety transformer is an isolation transformer.

[0015] The basic principle of the transformer is the principle of electromagnetic induction. Now take the single-phase double-winding transformer as an example to illustrate the principle of the transformer, which is also the working principle of the isolation transformer (as shown in the figure above): When a voltage is applied to the primary side winding When the current flows Alternating magnet...

Abstract

The invention discloses a safety transformer, which is used to convert a three-phase AC380V power supply into a stable AC220V without being affected by the interference of the AC380V power supply. The safety transformer includes five terminals, pin 1 and pin 2 are connected to three For any two phases of AC380V, pin 3 and pin 4 are voltage output terminals, and pin 5 is grounded. This device solves the problem that a system needs to provide multiple power sources, and the AC220V power supply provided by the transformer is safe and stable, avoiding the impact of the power grid, and has a certain protective effect on components.

Description

technical field [0001] The invention relates to the technical fields of electronics and electrics, and in particular to a safe transformer for converting a three-phase AC380V power supply into a stable AC220V without being affected by the interference of the AC380V power supply. Background technique [0002] Safety transformer is a kind of transformer. Due to the different power environments of countries and regions in the world, there are also differences in civil voltage, and the voltage application range of electrical appliances in various countries is also different. The common ones are 220V voltage and 110V voltage. With the rapid development of world technology The progress of people-to-people exchanges has become more and more frequent, and the AC converter has become a must-have item for people going abroad, which brings great convenience to people's work and life, saves money and reduces energy waste. [0003] AC converters are mainly divided into three types accord...
