This mobile vehicle-mounted test transformer has multiple core advantages. First, it is integrated with a standard 3.5-ton pickup truck, which can quickly move to any on-site testing scenario, realizing mobile high-voltage testing. Second, it adopts a sealed oil-immersed insulation structure, ensuring stable and reliable performance during long-distance transportation and outdoor use. Third, it is equipped with a portable control box, which can remotely control the operation of the test transformer, improving the safety of the testing process. In addition, it has a comprehensive safety protection system, including overvoltage protection, overcurrent protection and leakage protection, which effectively ensures the safety of operators and equipment. It also has a dedicated storage compartment for storing testing accessories, which is convenient for on-site testing work.
This product has professional technical specifications for mobile testing equipment. The rated output capacity is 20kVA, with a rated AC output voltage of 75kV, and the input voltage is 380V three-phase supplied by the vehicle-mounted power supply of the 3.5-ton pickup truck. The no-load current is controlled within ≤1.8% of the rated current, and the impedance voltage is ≤7%, ensuring stable and efficient operation. The insulation class reaches Class F, allowing stable operation within the ambient temperature range of -20℃ to 45℃, and the relative humidity can reach ≤95% without condensation. The cooling mode adopts natural oil cooling, which does not require additional power support. The mounted dimensions are 1500mm in length, 1000mm in width and 1600mm in height, with a unit net weight of 210kg, which is suitable for installation on a standard pickup truck. The protection grade is IP23, which can prevent rain and foreign objects from entering the equipment. It complies with IEC 60137 and GB 1094 standards, ensuring the reliability of the test data.
This 20kVA 75kV mobile vehicle-mounted oil-immersed test transformer is mainly applicable to on-site mobile testing scenarios. First, it is suitable for power supply companies to conduct on-site emergency testing and maintenance of high-voltage equipment in remote areas and outdoor scenarios. Second, it can be used by field maintenance teams to conduct insulation performance testing of power distribution equipment during the maintenance process. Third, it is suitable for mobile testing institutions to provide on-site testing services for customers in different regions. In addition, it can also be used for emergency testing of power equipment after natural disasters such as floods and typhoons, ensuring the rapid recovery of power supply.
