The SXBP Variable Frequency Series Resonance Test System is an advanced high-voltage testing solution engineered specifically for AC withstand voltage testing of large-capacity, high-voltage primary electrical equipment. Designed in strict accordance with international standards (such as IEC and IEEE equivalents to DL/T8496-2004 and GB50150-2016), this modular system combines high-voltage reactors in parallel and series configurations. It effortlessly handles massive capacitive loads including long-distance high-voltage power cables, Gas-Insulated Switchgear (GIS), SF6 circuit breakers, power transformers, and potential transformers (CVT). By utilizing variable frequency tuning (20Hz–300Hz), it ensures low harmonic distortion (waveform distortion rate < 1%) and delivers pure sinusoidal output, making it the ultimate testing asset for power utilities, electrical contractors, and high-voltage manufacturing plants.
AC Withstand Voltage Test for Power Cables: Safely tests long-distance XLPE insulated power cables with low power supply capacity requirements.
GIS & SF6 Switchgear Testing: Performs rigorous dielectric strength and insulation performance evaluations under field conditions.
Power Transformer & Mutual Transformer Testing: Evaluates main insulation integrity across frequencies ranging from 45Hz to 65Hz.
Wide Frequency Tuning Range: Operates smoothly within 20Hz to 300Hz with high frequency adjustment sensitivity (0.1Hz, stability < 0.05%).
Modular Reactor Combination: Flexible combination of epoxy-cast high voltage reactors to adapt to diverse voltage and current specifications (200kV to 2000kV).

Q1: How does this resonant system reduce the required power supply capacity?
A1: By utilizing series resonance (XL = XC), the test transformer's power supply only needs to cover the active power loss of the system (P = S/Q). This allows a small-capacity power source (e.g., 300kVA) to test massive capacitive loads up to 20,000kVA, significantly reducing site power requirements and equipment weight.
Q2: What safety protections are built into the SXBP system?
A2: The system features multiple safety layers including over-voltage protection, over-current protection, zero-start interlocking, flashover protection, and protective damping resistors to safeguard both operators and tested samples during sudden breakdowns.
