What are the advantages of inflatable test transformers?

Inflatable test transformers are important testing equipment in power testing. Electric power workers need to use various test transformers when conducting high-voltage tests and insulation withstand voltage tests on electrical equipment such as power transformers, transformers, and circuit breakers in the power system. So, due to its unique structure and different insulation media, inflatable test transformers have significant differences compared to general test transformers. So, what are the advantages of inflatable test transformers? Below, the editor will introduce each one to you.

1. Small size and light weight

Traditional experimental transformers are generally bulky and heavy due to the filling of insulating oil. The inflatable test transformer, due to its compact structure and the filling of insulation gas, makes it lightweight and can be easily placed on a car, handcart, or directly on the ground for on-site testing.

2. Low cost, high efficiency

The inflatable test transformer achieves high-voltage testing by compressing the insulation gas, so the cost is very low and its energy loss is also very small. However, traditional test transformers require specialized high-voltage generators to generate high-voltage electric fields and currents in order to achieve the required test voltage.

3. Safe and reliable operation

The iron core of the inflatable test transformer is made of high-quality silicon steel sheets laminated. Because its operation is carried out without load, it will not have any impact on the power system itself and electrical equipment. However, traditional test transformers must have issues such as load voltage regulation or DC bias during operation, which can have a certain impact on the power system.

4. Perfect protection function

The inflatable test transformer also has very complete protection functions. For example, during the discharge process, if there is a situation where the discharge cannot be automatically discharged, there will be an automatic protection device that automatically disconnects the power supply; When the insulation is insufficient, there will also be automatic protection functions, such as low voltage alarm or overcurrent, overheating, etc.

5. Insulation medium gas is clean and free from oil pollution

Due to the fact that the insulation medium filled inside the inflatable test transformer is SF6 insulation gas, there is no oil pollution and it is cleaner.

Compared with traditional oil immersed light test transformers, the ZC-501B inflatable test transformer reduces weight by 20-60% (depending on voltage and capacity level), and has no oil pollution. The voltage level of a single inflatable test transformer can reach 300kV. Due to the adoption of a new production process, the technical performance of the inflatable test transformer has been greatly improved, making it particularly suitable for on-site work and frequently moving working conditions.
