Application
The series resonance device is widely used in power systems, railways, metallurgy and other fields.
It is used for on - site AC withstand voltage test of GIS (Gas Insulated Switchgear) to effectively check the internal insulation defects of GIS.
It is used for withstand voltage test of high - voltage cross - linked cables to provide the required AC test voltage and current for long - distance and large - section cables.
It is used for AC withstand voltage test of large generators and motors to meet their high - voltage and large - capacity test requirements.
It is used for AC withstand voltage test of transformers and switchgear.
It is used for on - site test of photovoltaic and wind power booster stations.
Main Features
Resonance voltage boosting: By adjusting the output frequency, the reactor and the test sample capacitor generate series resonance, so that a much higher high voltage than the power input voltage is obtained on the test sample.
Automatic tuning: It automatically finds the resonance point and can automatically track and maintain the resonance state when the test sample capacitance changes, with simple operation.
Effective protection of test samples: During resonance, if the test sample breaks down, the circuit is detuned, the high voltage drops rapidly, and the short - circuit current is small, which can effectively prevent damage to the test sample.
Small power supply capacity required: During resonance, the power supply only needs to provide the active power loss in the circuit, so the required input power supply capacity is only 1/Q of the test sample capacity (Q is the system quality factor), which greatly reduces the requirements for the power supply.
Small size and light weight: Compared with the traditional power frequency test transformer, under the same capacity, the size and weight of the device are greatly reduced, which is especially suitable for on - site tests.
