[0002] New energy refers to renewable energy that is systematically developed and utilized based on new technologies, such as solar energy, wind energy, biomass energy, geothermal energy, ocean energy, hydrogen energy, nuclear energy, etc. New energy power generation is the process of generating electricity using existing technologies and the above-mentioned new energy sources. However, new energy power generation has the characteristics of intermittent, random, and volatile. To achieve safe and stable electricity use, it is necessary to equip with sufficient and flexible adjustable power sources.
[0003] New energy power generation equipment also includes chassis, converters, generator bodies, inverters, guide wheels, transformers and wires, etc. These devices usually form an overall cabinet structure, and these electrical components work in the cabinet. After long-term use, it is easy to cause parts damage. Therefore, the cabinet often needs to be repaired or cleaned. New energy power generation equipment usually generates electricity intermittently. Therefore, when repairing the cabinet, it is easy to cause safety accidents such as leakage.
