Winding of dry-type transformer

When we buy a Transformer, we often pay attention to its winding. What is winding? Zhenhua small editor for your professional explanation about the transformer winding.

The winding of dry-type transformer is a group of wire turns of electrical circuit corresponding to a certain voltage value marked by dry-type transformer. The detailed application of winding is dry-type transformer. The core of dry-type transformer is wound with one primary winding and several secondary windings. As the number of turns of each secondary winding is different, its terminal voltage is also different. Therefore, dry-type transformer with multi winding can supply power to several electrical equipment with different voltages. In the dry-type transformer power system, the most commonly used is the three winding transformer. Using one three winding transformer to connect three different voltage transmission systems is more economical, less occupied and more convenient for maintenance and management than using two general transformers. Generally, Y-Y - △ connection method is adopted for three-phase three winding transformer, that is, the primary and secondary windings are Y-connected, and the third winding is connected to △. The delta connection method itself is a closed circuit, which can pass through the third harmonic current in the same phase, so that there is no third harmonic voltage in the primary and secondary windings of Y connection. This can provide a neutral point for both primary and secondary sides. In the long-distance transmission system of dry-type transformer, the third winding can also be connected with synchronous condenser to improve the power factor of dry-type transformer line
