This series resonance matching oil-immersed test transformer focuses on resonance matching accuracy and system compatibility, addressing the challenges of traditional test equipment that cannot meet the testing requirements of large-scale GIS and cable systems. It is specially matched with a series resonance reactor system, ensuring stable resonance frequency and accurate voltage output during testing. The natural + forced oil circulation cooling mode ensures stable heat dissipation during continuous high-load testing, extending the service life of the equipment. The compact structural design reduces the overall footprint, making it suitable for indoor and outdoor test sites. The IP54 protection grade can prevent dust and splashing water from entering the equipment, making it suitable for harsh outdoor environments. It is equipped with a dedicated voltage monitoring system, providing real-time voltage and current data during testing to ensure the safety of the test system.
This series resonance matching oil-immersed test transformer has a rated AC output voltage range of 0-150kV and a rated capacity of 50kVA, suitable for matching with 100kVA series resonance reactor systems. It supports 380V three-phase input voltage, compatible with most large industrial power supplies. With an H-class insulation grade, it can withstand long-term high-voltage operating loads without significant insulation aging. The natural + forced oil circulation cooling mode ensures stable heat dissipation during continuous high-load testing sessions. The net weight of 450kg and compact overall dimensions make it easy to transport and deploy on test sites. It meets the safety standards of IEC 61850, GB/T 19483, and ANSI C57.12.01, with a protection grade of IP54 to adapt to harsh outdoor weather conditions. The output waveform is a standard sine wave, ensuring stable resonance matching during series resonance testing.
This series resonance matching oil-immersed test transformer is widely used in series resonance high-voltage testing scenarios, including voltage withstand tests for GIS equipment, 110kV and 220kV power cables, large-scale transformers, and reactor equipment. It is suitable for power grid maintenance teams, substation construction companies, large electrical equipment manufacturers, and third-party testing institutions. The device can be seamlessly matched with series resonance reactor systems to form a complete high-voltage testing system, providing accurate and reliable testing services for large-scale electrical equipment, helping users identify potential safety hazards and ensure the safe and stable operation of power grid systems.
