• What are the functions of the four components of series resonance

        The series resonance under Wuhan UHV can help many power workers more conveniently conduct various power tests.


        The four main components of series resonance include excitation transformer, voltage divider, variable frequency power supply, and high-voltage reactor. These components play crucial roles in series resonant circuits, together ensuring the normal operation and functionality of the circuit. Here are their specific functions:

        Excitation transformer:

        Function: The main function of the excitation transformer is to boost the voltage output by the variable frequency power supply to meet the needs of high-voltage testing or measurement. At the same time, it can also play a role in isolating high and low voltage, ensuring the safety of the circuit.

        Importance: As a crucial component for boosting and isolating, the excitation transformer is crucial for the stable operation of series resonant circuits.

        Voltage divider:

        Function: The voltage divider is used to measure the high voltage and low voltage values on the regulator. It can divide high voltage into measurable low voltage, making it convenient to accurately measure and monitor the voltage in the circuit.

        Importance: The voltage divider provides a real-time monitoring method for the voltage in the circuit, which helps to detect voltage anomalies in a timely manner and ensure the safe operation of the circuit.

        Variable frequency power supply:

        Function: Variable frequency power supply is one of the core components in series resonant circuits, which can convert fixed frequency power supplies (such as 220V/380V, 50Hz) into frequency adjustable and continuously adjustable voltage power supplies. At the same time, it also integrates various functions such as operation, protection, control, monitoring, etc., providing comprehensive support for the operation of the circuit.

        Importance: The adjustability of variable frequency power supplies enables series resonant circuits to adapt to different testing or measurement needs, while also improving the flexibility and reliability of the circuit.

        High voltage reactor:

        Function: High voltage reactors are used in series resonant circuits to induce series resonance with capacitive specimens. By interacting with capacitors, high-voltage reactors can achieve resonance in a circuit at a specific frequency, thereby maximizing the voltage and current in the circuit.

        Importance: High voltage reactors are one of the indispensable components in series resonant circuits, and their performance directly affects the resonance effect and measurement accuracy of the circuit.

        In summary, the four components of series resonance each have unique roles and importance. They work together to ensure that the series resonant circuit can operate stably and reliably, meeting various experimental or measurement needs. In practical applications, the performance and parameters of these components need to be selected and adjusted according to specific experimental or measurement requirements.
