Portable Series Resonant AC Withstand Test System for 220kV Cable Testing
The SXBP Series Resonant AC Withstand Test System is specifically engineered for AC withstand voltage testing of high-capacity, high-voltage primary equipment in power systems. This portable system meets regulatory requirements for on-site AC withstand voltage testing of various capacitive equipment.
System Overview
Featuring high-voltage test reactors with series-parallel combination capability, this system accommodates voltage withstand testing for high-voltage transformers, GIS systems, SF6 circuit breakers, transformers, bushings, and long-distance cross-linked cables. Its wide compatibility with diverse test samples makes it an ideal solution for power supply system maintenance and power engineering construction applications.
Key Features
- Comprehensive protection functions including overvoltage, overcurrent, zero start, and system detuning (flashover) protection
- Compact design with equipment weight and volume reduced to 1/10-1/30 of conventional testing devices
- Energy-efficient operation requiring only 1/Q of test capacity power
- Three operational modes: fully automatic, manual, and automatic tuning manual boost
- Data storage and printing capabilities with numerical identification for easy retrieval
- Customizable frequency scanning starting point within specified ranges
- DSP platform technology supporting function addition, removal, and upgrades
- Enhanced output voltage waveform quality
- Protection against large short-circuit currents to prevent fault point damage

Model Notation: SXBP-27/54/108-108 where SXBP is the series model, 27/54/108 represents voltage of one reactor (kV)/voltage of two reactors in series connection/voltage of four reactors in series connection, and 108 indicates total capacity (KVA). For lower capacity or voltage requirements, additional reactors can be added to increase capacity, and more dividers can be added to increase test voltage.
