The control transformer is to control them within a required range of use according to the voltage and current required by the electrical equipment.
The isolation transformer is used when the electrical appliance is repaired with a hot plate, that is, a line of the hot plate and the AC power supply is directly connected.Once it touches the plate, because the live wire has a potential difference of 220 volts with the earth, a loop is formed between the plate, people, and the earth, and an electric shock occurs. The danger of re-powering through the isolation transformer, the alternating current is completely separated from the bottom plate, the transmitted voltage will not change at 220 volts, and there will be no current passing through the human body when touched.
1. Different purposes:
The control transformer is used as the power supply of the electrical control loop to meet the voltage requirements of different electrical components.
Isolation transformer one is to isolate and transmit the different voltages or required voltage signals at the two ends of the transformer through the isolation transformer, so that the different voltages at the two ends of the transformer will not interfere or affect each other, such as some thyristor or IGBT circuits. Drive coil; second, need different impedance matching, such as some audio power amplifiers; third, for personal safety, such as running light transformer.
2. Different functions:
The control transformer is to provide power for the control system during the operation of electrical equipment;
The isolation transformer is to prevent the electrical equipment from being interfered by the harmonics of the power supply. In fact, it is a poor performance filter. Generally, the output voltage of the control transformer is 6.3V, 12V, 24V, 36V, 50V,
110V, 127V, etc., in order to reduce costs, some control transformers only output a single low voltage, or three to five voltages. Generally speaking, isolation transformers have a transformation ratio of 1:1. The two types of transformers have different functions and cannot be used universally.
3. Contact:
For example, in the electrical circuit of an imported vehicle, all electrical relays, contactors, etc. are 220 volts, and the power input is 3-phase 4-wire. The neutral wire could be used directly to form the control circuit. But this driving
With the control handle, the electrical designer uses an isolation transformer. The secondary is used as the power supply of the electrical control loop. Since this secondary loop has no grounding terminal, even if a person touches one of the 220-volt control voltages.
The point will not get an electric shock, so this transformer is both a control transformer and an isolation transformer.
Here we can also see that the definition of a transformer name is also determined by the purpose of the transformer itself, such as: an isolation transformer is called an isolation transformer!
