Description

technical field [0001] The invention relates to a high-voltage transformer, in particular to a safe pressure-resistant breakdown-proof high-voltage transformer box. Background technique [0002] In power equipment, high-voltage transformers have been widely used. High-voltage transformers are suitable for converting large voltages into small voltages or large currents into small currents in 1kv to 220kv power systems for easy measurement, protection, and use. device. At present, with the rapid development of the national economy, more and more places need to use electricity. Since the transmission of electricity is generally carried out in the form of high voltage for long-distance transmission, it is necessary in residential areas or general construction sites at the end of electricity consumption. Transformer equipment is used, and high voltage transformers are usually used in transformer equipment. However, during the use of high-voltage transformers, due to the increas...
