Description

Product Description

The SXBP Variable Frequency Series Resonance Test System is engineered for high-voltage AC withstand testing of large-capacity electrical equipment and capacitive loads. Based on variable-frequency series resonance technology, the system combines a variable-frequency power supply, excitation transformer, resonant reactor and related compensation components to establish a controlled resonant circuit. By adjusting the operating frequency, the system can adapt to different test loads and generate the required high AC voltage.

Main System Components

System Component Purpose
Variable Frequency Power Supply Provides adjustable-frequency excitation power
Excitation Transformer Matches the excitation voltage and system requirements
Series Resonant Reactor Establishes the resonant circuit with the test load
Protection Inductor Provides additional circuit protection
Compensation Capacitor Supports reactive compensation and resonance adjustment
Control & Protection Unit Controls operation and monitors key test parameters

Key Benefits

High-Voltage Capability Configurations from 200 kV to 2000 kV support a wide range of HV and EHV insulation testing applications.

Large-Capacity Testing The system covers 300 kVA–20,000 kVA, making it suitable for large-capacity test objects and demanding test projects.

Variable-Frequency Control The 20–300 Hz frequency range provides flexibility when working with different capacitive loads.

Efficient Resonant Operation Series resonance technology makes the system particularly suitable for high-capacitance electrical equipment.

High-Quality Output The specified waveform distortion is ≤1%, helping maintain consistent AC testing conditions.

Precise Frequency Adjustment With 0.1 Hz frequency adjustment resolution, the resonance point can be adjusted with high precision.

Typical Applications

Application Typical Test Objects
Power Cable Testing 110 kV / 220 kV / 500 kV cables
GIS Testing GIS, SF6-insulated switchgear
Transformer Testing Power transformers
Switchgear Testing HV switchgear and circuit breakers
Laboratory Testing High-voltage electrical apparatus
Field Testing Substations and power infrastructure

FAQ

1.Can the SXBP system test 220 kV cables? Yes. The system can be configured for 220 kV power cable AC withstand testing. Cable length, capacitance, required test voltage and test duration should be provided for accurate configuration.

2.Can it be used for 500 kV cable testing? Yes. The SXBP series can be engineered for 500 kV cable testing and other EHV applications within the required technical range.

3.What is the output frequency? The output frequency range is 20–300 Hz.

4.Why is the frequency adjustable? Because different test objects have different capacitance values. Variable-frequency operation allows the system to adjust the resonant condition according to the electrical characteristics of the load.
