Jiangsu Dary Electric Co., Ltd. recommends the series resonance device for you.
Series resonance is a good helper for withstand voltage tests, all because of the advantages of series resonance in high voltage testing. One particular advantage of the series resonance test device is that it is very convenient to carry and move.
Withstand voltage tests are indispensable in power systems, and the insulating media on power equipment need to undergo such tests. Generators, cables, and substations all require the use of series resonance. During the installation or renovation of cables, series resonance is used to test the withstand voltage performance of the cables, ensuring safety and stability before they are put into power operation. Routine cable safety maintenance also requires the use of series resonance.
In power systems, cable installation is generally carried out outdoors, sometimes in remote areas where large test equipment is difficult to move. Series resonance perfectly solves this problem. Due to the variable frequency power supply of series resonance, the power capacity is greatly reduced. The variable frequency power supply uses the resonance reactor and the capacitance of the test object to generate high voltage and large current. In the entire system, the power supply only needs to provide the active power consumption part, so the power required for the test is only 1/Q of the test capacity. The weight and volume of the series resonance equipment are greatly reduced. Since a variable frequency power supply is used, the bulky high-power voltage regulating device and the ordinary high-power power frequency test transformer are eliminated, thus reducing the volume and weight of the test device. This facilitates the work of power workers! In addition, the split structure also makes the application of the series resonance test device more flexible and versatile.
