Principle of transformers

Principle of transformers

Composed of two windings independent of the iron core! Here is an introduction to the principles of transformers!

I will introduce the principles of a transformer. A transformer consists of a core made of iron and two independent windings. The winding connected to the power source is called the primary winding, and the winding connected to the load is called the secondary winding. When an alternating voltage is applied to the primary winding (P), a current flows through it (referred to as the excitation current), which generates a magnetic flux within the core. This change in magnetic flux induces a voltage in the secondary winding (S), and the induced voltages V1 and V2 in the primary and secondary windings are determined by the ratio of the number of turns in the primary winding N1 to the number of turns in the secondary winding N2. When a voltage is applied to the primary winding, a voltage proportional to the number of turns is induced in the secondary winding, and by changing N1 and N2, the ratio of the primary voltage to the secondary voltage can be arbitrarily altered. *For more details, please refer to the PDF document or feel free to contact us.*

Insulation type of transformer

Insulation type of transformer

The temperature rise limit is defined by the insulating materials used! An introduction to the types of insulation for transformers.

Transformers are reliable and long-lasting devices, but prolonged use can lead to deterioration of the winding insulation and insulating materials due to temperature effects. They are also significantly affected by the ambient temperature in which they are used. To ensure safe long-term use, temperature rise limits are established based on the insulating materials used, and each type of insulation material has its own specified temperature rise limit. The maximum allowable temperature, under rated conditions, is the temperature rise limit of the insulation type plus the reference ambient temperature (40°C). When installed and used in control panels, it is generally necessary to consider that the internal temperature rise of the panel can be 5 to 10°C. *For more details, please refer to the PDF documentation or feel free to contact us.

[Case Study] From Character Development to LINE Sticker Production

[Case Study] From Character Development to LINE Sticker Production

There are 40 types of stamps! We are considering expressions and phrases that will be easy to use for those who purchase them.

Previously, our designer was responsible for the character design of GS Yuasa Battery Co., Ltd.'s eco-character "Shigeru-kun the Forest Hedgehog," so we received this order with a specific request for the same designer. In creating the stamps, we focused on ensuring that they would be friendly to customers who purchase them, as well as having a design and expressions that are easy to use. Additionally, we created PR cards that allow direct access to the stamps via a QR code. [Case Overview] ■ GS Yuasa Battery Co., Ltd. ■ 40 types of LINE stamps ■ Date: May 2015 *For more details, please refer to the PDF document or feel free to contact us.
