The need to increase or decrease stress arises quite often. In fact, all electric household tools and devices are powered by 220 V or 380 V networks, but their operating voltage is many times less. Therefore, it is necessary to lower the voltage in order to avoid the ignition of equipment. It is for this that there are so-called step-down transformers, in particular, the TSZI transformer.
In general, by type of design, by designation, by technical characteristics and design, there are a huge number of different transformers. For example, even by cooling methods, you can divide them into oil and dry. TSZI transformer is a step
- down
three-phase transformer, dry, in a protected version.
Such electrical machines are usually used in order to lower the voltage in three-phase circuits. TSZI transformer is usually installed in workshops, cellars, industrial premises, in service stations, in places and at enterprises with increased requirements for fire safety, sanitary standards, and explosion safety. Often they are used to power electrical appliances, industrial lighting lamps, power tools.
TSZI transformer is an electromagnetic device that converts an alternating current of one voltage into a current of another voltage. The operation of such an electric machine is based on the famous principle of mutual induction, which acts through magnetic fields and is used to transfer energy from one circuit to another circuit of the transformer.
The transformer TSZI consists of windings and a core. Two-winding, three-winding and multi-winding transformers are poured, depending on the windings and their number. The primary winding is the one that connects to the power supply (source). The winding to which the device is connected is called secondary. If the output voltage is less than the input, then such a transformer is called step-down, if more - then step-up. When a transformer is connected to a source, alternating current causes a magnetic field on the primary winding. And since both windings are on the same core, the secondary winding will be in a magnetic field. If a load is connected to the secondary winding, then current will pass through the circuit and produce the required voltage.
The value of the voltage value depends on how many turns on the windings of such electrical machines as transformers TSZI. For example, if there are two thousand turns on the primary winding and two hundred turns on the secondary, then such an important parameter as the transformation ratio will be equal to ten. That is, by connecting a step-down transformer TSZI to a network of 220 V, the output can be 20 V. Similarly, the transformation coefficient parameter is calculated to increase the voltage in the network. However, it is believed that a good step-down device is one in which this coefficient will be less than one. Since such a voltage transformation is a widespread need, such electric machines are used very widely.
