Isolation transformer application -Mobikechip
In modern electrical systems, isolation transformers, with their excellent electrical isolation performance, have become an important component to ensure the stable operation of various types of equipment and the safety of personnel. Today, MobikeChip will take you to explore the wide range of applications of isolation transformers.
Key applications in industrial production
(A) automated production lines
In the industrial automated production line, many complex electrical equipment work together. Electromagnetic interference and potential difference generated by different equipment may lead to control system failure, affecting production accuracy and efficiency. Isolation transformers play a key isolation role in this. For example, in automobile manufacturing production lines, mechanical arms, sensors, controllers and other equipment are electrically isolated by isolation transformers. The isolation transformer will effectively separate the strong power equipment and weak power control circuit, to prevent the strong power interference signal into the weak power system, to ensure the accurate transmission of control instructions, to ensure the accurate operation of the production line, to avoid production errors and equipment damage caused by interference.
(B) Motor drive system
A large number of motors are used in industry to drive various mechanical equipment. Motor in the start and operation process will produce large current fluctuations and electromagnetic noise, these interferences will not only affect the performance of the motor itself, but also may have an impact on other equipment in the same circuit. Isolation transformers are used in motor drive systems to isolate the electrical connection between the motor and the power supply as well as other equipment. It can effectively inhibit the interference signal generated by the motor feedback to the power grid, while preventing stray waves in the power grid to interfere with the normal operation of the motor. In large fans, pumps and other motor-driven equipment, the application of isolation transformers greatly improves the stability and reliability of motor operation, extending the service life of the equipment.
The medical industry is an important safeguard
(A) medical testing equipment
Medical testing equipment such as magnetic resonance imaging (MRI), computerized tomography (CT) and other electrical signal accuracy and stability requirements are extremely high. Isolation transformer plays a vital role in these equipments. It isolates interference from the external power grid and ensures that the human physiological signals captured by the equipment are accurate. For example, in the MRI equipment, the isolation transformer can not only prevent the electromagnetic interference in the power grid to affect the quality of imaging, but also avoid the electrical interference between the equipment, to ensure the clarity of the image and diagnostic accuracy, to provide doctors with a reliable diagnostic basis.
(B) operating room medical equipment
Life support equipment and surgical instruments in the operating room are directly related to the life safety of patients. The isolation transformer provides a safe and reliable electrical environment for these devices. It can effectively avoid the risk of electric shock suffered by patients during surgery due to leakage of electrical equipment. For example, pacemakers, shadowless lamps and other equipment are connected to the power supply through the isolation transformer to ensure that the equipment operates stably, while safeguarding the safety of patients and healthcare personnel, and providing a solid electrical guarantee for the smooth operation of the surgery.
Applications in Power Systems
(A) Substation
In the substation, the isolation transformer is used for the connection and isolation between power grids of different voltage levels. It can isolate the high-voltage power grid from the low-voltage distribution network, prevent the faults and disturbances on the high-voltage side from being transmitted to the low-voltage side, and protect the safety of the electrical equipment and users on the low-voltage side. At the same time, the isolation transformer can also play the role of voltage transformation, to meet the needs of different users of the voltage level. For example, in the 110kV high-voltage power converted to 10kV medium-voltage power for urban distribution network, isolation transformer not only realizes the conversion of voltage, but also ensures the electrical isolation between high-voltage and low-voltage power grids, improving the stability and reliability of the power system.
(B) Power transmission lines
In long-distance power transmission lines, isolation transformers are used to isolate the electrical connection between different line segments. It can reduce the electromagnetic induction and capacitive coupling between the lines, and reduce line losses and interference. For example, in the high-voltage transmission line across different regions, the isolation transformer can prevent the mutual influence between different regional power grids, ensure the stability and security of power transmission, and guarantee that the power can be reliably delivered to various power-using regions.
The application of electronic equipment
(A) audio equipment
In audio equipment such as sound systems, recording equipment, isolation transformers are used to isolate the electrical interference between different devices to improve the quality of the audio signal. For example, in professional recording studios, microphones, mixers, power amplifiers and other equipment connected through the isolation transformer. The isolation transformer can effectively eliminate noise and interference between devices, making the recorded and played audio clearer and purer, and bringing users a high-quality listening experience.
(B) communication equipment
Communication equipment such as switches, routers and other electrical stability requirements are very high. Isolation transformers are used in the power input and signal transmission parts of these equipments, which can isolate the interference and surge in the power grid and protect the communication equipments from the influence of electrical faults. It also prevents signal interference between communication devices, ensures the accuracy and stability of data transmission, and guarantees the normal operation of communication networks.
