Recently, the company officially launched a series of variable-frequency series resonance devices, including variable-frequency series resonance test complete sets, variable-frequency series resonance withstand voltage devices, series resonance withstand voltage equipment, series resonance test devices, etc., suitable for AC withstand voltage testing of power equipment such as 35kV cables of 1km. The launch of this series of products further enriches the company's product line in the field of power testing equipment.
The variable-frequency series resonance device adopts the principles of variable-frequency regulation and resonance voltage boosting. By adjusting the output frequency, the circuit is brought to a resonance state, thereby obtaining the required high voltage on the test object. The device is mainly composed of a variable-frequency power supply, excitation transformer, reactor, capacitive voltage divider, etc. It features good output waveform, stable voltage, and relatively light weight, making it suitable for on-site testing.
In power systems, AC withstand voltage testing of equipment such as XLPE cables, GIS, and transformers is an important means of verifying insulation performance. The variable-frequency series resonance device can meet the requirements of such tests for test voltage, frequency, and capacity. Taking a 35kV cable of 1km as an example, the device can achieve resonance by combining reactors according to the cable capacitance and test voltage requirements, completing the withstand voltage test.
The series of variable-frequency series resonance devices launched by the company this time focuses on practicality and reliability. The device adopts a modular design, facilitating transportation and on-site assembly; the control part has overvoltage and overcurrent protection functions, and the operation interface is simple, convenient for test personnel to use. At the same time, the company can provide customized solutions according to user needs, including complete sets with different voltage levels and different capacity configurations.
The company has always been committed to providing safe and reliable testing equipment for the power industry. In the future, we will continue to optimize product performance, improve service systems, and provide support for the safe operation of power equipment. New and old customers are welcome to inquire and learn more.
