These advantages are described in detail below:
1. Small size and light weight
· Portability: Inflatable test transformers are designed to greatly reduce their size and weight, typically 20 to 60 percent lighter than traditional oil-immersed test transformers. This lightweight nature makes the equipment easy to handle, especially in conditions requiring frequent movement or field testing.
Easy transportation: Due to its small size and light weight, inflatable test transformers can be easily placed on vehicles, trolleys, or even placed directly on the ground for field testing when needed. This not only reduces transportation costs, but also increases the flexibility and scope of application of the equipment.
2. Environmental safety
No oil pollution: inflatable test transformers use SF6 gas as an insulating medium, rather than traditional insulating oil. This effectively avoids the problem of oil pollution and reduces the negative impact on the environment.
· High safety: Since no insulating oil is used, the inflatable test transformer does not have the risk of fire caused by oil leakage. At the same time, SF6 gas has good insulation performance and arc extinguishing ability, and can operate safely under high pressure conditions.
3. Low cost and high efficiency
· Manufacturing and maintenance costs: The structure and design of inflatable test transformers are relatively simple, and the manufacturing cost is low. Due to its safe and reliable operation, it reduces the need for maintenance and repair, thus further reducing the cost of long-term use.
· Operation efficiency: The energy loss of the inflatable test transformer is very small, and the efficiency is high, which can meet the requirements of power equipment testing. Its efficient performance not only saves energy, but also improves test efficiency.
4. Perfect protection function
· Automatic protection: inflatable test transformers have complete protection functions, including overload protection, short circuit protection and ground protection. During the test process, these protection mechanisms can effectively prevent equipment damage and safety accidents.
· Abnormal alarm: If the discharge cannot be automatically discharged, the automatic protection device will disconnect the power supply immediately; When the insulation is insufficient, there will also be low voltage alarm or over current, over temperature and other automatic protection functions to ensure the safety of equipment and operators.
5. High insulation performance
· Insulation strength: SF6 gas has excellent insulation performance, and the insulation strength of the test transformer filled with this gas is significantly higher than that of the oil-immersed test transformer under high voltage, and the corona is very small. This makes inflatable test transformers particularly suitable for high-precision test requirements.
· No partial discharge: The high voltage tower coil is continuously wound on the special high-strength insulating cylinder, and basically no partial discharge phenomenon. With high precision office discharge instrument, it can accurately measure the office discharge volume of the subject.
6. Strong versatility
· Multi-occasion application: The inflatable test transformer is especially suitable for power systems, industrial and mining enterprises, scientific research departments, etc., for various high-voltage electrical equipment, electrical components, and insulation materials under power frequency or DC high voltage insulation strength tests.
· High-precision testing: Due to its high insulation properties and small corona, inflatable test transformers can perform high-precision testing, such as partial discharge testing, winding resistance and insulation resistance measurement.
