Introduction
Power frequency transformers are used to propagate signal voltage and signal power, and can also achieve impedance matching between circuits, which has an isolation effect on direct current. There is no difference in principle between high-frequency transformers and low-frequency transformers. However, due to the different frequencies of high and low frequencies, the iron core used in the transformer is different. Low-frequency transformers generally use silicon steel sheets with high permeability.
Scope of application
1. Industrial automation: Power frequency transformers are usually used in motor speed regulation, various industrial equipment control power and other fields. Such as: fans, pumps, manufacturing equipment, etc.
2. Construction industry: Places in the construction industry that need to use high-voltage power supplies, such as high-rise buildings, parking lots, large shopping malls, offices and houses, hotels, etc., need power frequency transformers to convert voltage.
3. Power industry: Power frequency transformers are also widely used in the power industry. Especially in the transmission process, electrical energy needs to be stepped up and down through transformers before it can be transmitted over long distances. Power frequency transformers are very important at this time.
4. Railway, urban transportation and other fields: There are also a large number of power frequency transformer applications in railways, subways, buses and other transportation equipment, which are used for electromagnetic chuck brakes, passenger car air conditioning, lighting, etc.
5. Communication industry: Some equipment in the communication industry needs to use a specific voltage, which requires voltage transformation through a power frequency transformer.
Equipment characteristics
1. Safety: The internal structure of the power frequency transformer will not produce any radiation/electromagnetic interference, and will not cause safety hazards such as fire.
2. Reliability: will not be damaged by electromagnetic waves.
3. Economy: Compared with other transformers, the cost of power frequency transformers is relatively low, which is very economical and practical.
4. Applicability: Power frequency transformers can be used in a variety of occasions to meet the needs of different users for voltage and current.
