Background
The transformer is an electromagnetic device which converts electric energy into magnetic energy and then converts the magnetic energy into electric energy by applying the law of electromagnetic induction so as to realize voltage conversion. With the development of global economy, the installed capacity of a power system is continuously increased, the transmission voltage level is continuously improved, and the market demand for high-capacity ultrahigh-voltage transformers is also increased. The volume of a large-capacity ultrahigh-voltage transformer is increased, and under the background that the land space is in daily shortage and expensive, the application of a plug-in type wire outlet device of the transformer is more and more. The general conventional transformer adopts an oil-air sleeve or an oil SF6 sleeve structure, and compared with the conventional transformer, the structure is more suitable for indoor use, saves space, is safe and reliable, can adopt an insulated cable to be directly led out, and can better arrange a circuit according to actual needs. However, the electric field strength is likely to be too high, and thus the transformer test cannot be performed.
