Description

Transformer core assembly device and transformer core assembly method using same {TRANSFORMER MANUFACTURING DEVICE AND MANUFACTURING METHOD THREROF}

The present invention relates to a device for assembling the iron core of the transformer and an assembling method using the same, and more particularly, to finely adjust the seating position of the iron core in assembling the iron core of the transformer to shorten the working time to improve productivity The present invention relates to an iron core assembly apparatus of a transformer capable of reducing labor costs and an assembly method using the same.

In general, a transformer is a stopper that changes the value of an AC voltage or an electric current by using electromagnetic induction. A power transformer is a transformer that changes a voltage applied to an AC circuit to a higher or lower voltage. And power has the same characteristic.

In such a transformer, the primary winding connected to the power supply and the secondary winding connected to the load are wound on the same iron core, and the iron core is assembled to the required thickness by overlapping magnetic materials such as silicon steel sheet, permalloy, and ferrite having a thickness of 0.35 mm. .

The actual structure of the transformer varies depending on the capacity and voltage, but the important parts are the windings and the iron core, which are put into the tank to increase the dielectric strength, and to insulate the heat generated from the iron core or the winding by oil convection or radiation. It is filled up.

The core is composed of a thin strip of silicon without using a thin sheet of silicon, and the strip is laid until the required cross-sectional area is obtained like a tape. It is therefore widely used.

The winding function consists of a conductor, such as copper or aluminum, which induces magnetic induction by flowing a current through the conductor, and an insulator that insulates it from other parts.
