Outdoor 200kV High-Capacity Oil-Immersed Test Transformer

Product features:

This high-capacity 200kV oil-immersed test transformer focuses on large-load stability and outdoor durability, addressing the pain points of traditional test equipment that cannot meet the testing requirements of ultra-high voltage substation equipment. It adopts a forced oil circulation cooling system, which can quickly dissipate heat during continuous high-load testing, ensuring stable equipment performance for 8 hours of continuous operation. The high-purity naphthenic insulating oil has a breakdown voltage of over 60kV, effectively reducing partial discharge and extending the service life of the equipment. The IP54 protection grade can prevent dust and splashing water from entering the equipment, making it suitable for harsh outdoor environments such as coastal areas and construction sites. It is equipped with a dedicated remote control console, allowing operators to complete voltage regulation and data collection at a safe distance, reducing the risk of high-voltage accidents.

Product specifications:

This outdoor oil-immersed test transformer has a rated AC output voltage range of 0-200kV and a rated capacity of 100kVA, suitable for ultra-high voltage substation and long-distance transmission line testing scenarios. It supports 380V three-phase input voltage, compatible with large industrial power supplies. With an H-class insulation grade, it can withstand long-term high-voltage operating loads without significant insulation aging. The forced oil circulation cooling mode ensures stable heat dissipation during continuous high-load testing sessions. The net weight of 850kg and heavy-duty structural design ensure stable placement on outdoor construction sites. It meets the safety standards of IEC 60601, 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, and the voltage regulation accuracy is within ±0.2%, ensuring highly accurate test results for large-scale testing projects.

Product application:

This 200kV high-capacity oil-immersed test transformer is widely used in large-scale outdoor high-voltage testing scenarios, including voltage withstand tests for 110kV and 220kV transformers, circuit breakers, and GIS equipment, insulation performance testing of long-distance transmission line insulators, and factory acceptance testing of large electrical equipment. It is suitable for power grid construction companies, ultra-high voltage substation maintenance teams, large electrical equipment manufacturers, and third-party national-level testing institutions. The device can provide reliable high-voltage testing services for large-scale power transmission and distribution equipment, helping users identify potential safety hazards and ensure the safe and stable operation of power grid systems.
