Abstract

The invention discloses a protection structure for a wind power generation frequency converter in the technical field of wind power generation, the protection structure comprises a protection box and a frequency converter main body, the top and the bottom of the protection box are fixedly connected with mounting sleeves, the top of the protection box is provided with a wire inlet seat, and the bottom of the protection box is provided with a wire outlet seat; the wire inlet seat and the wire outlet seat are both embedded in the mounting sleeve, an antenna is arranged at the top of the protection box, the antenna is fixedly connected with the protection box, a box cover is fixedly connected to one side of the protection box through a hinge, an exhaust fan is fixedly connected to the other side of the protection box, and a corrugated pipe is fixedly connected to the output end of the exhaust fan. According to the invention, the dustproof effect is good, heat dissipation can be carried out in the protection box according to the temperature monitoring condition, the service life of the frequency converter main body is prolonged, the economical efficiency is good, in addition, if the input voltage is abnormal, the control box can cut off the input end of the frequency converter main body, the protection effect is good, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a protective structure for a wind power frequency converter. Background technique [0002] With the continuous development of wind power technology, wind power has become one of the main sources of green energy in my country. The development prospects of China's wind power and other new energy power generation industries are very broad. It is expected to maintain high-speed development for a long time in the future, and at the same time, profitability will steadily increase with the gradual maturity of technology. With the development of wind power generation, although wind power generation equipment is gradually upgraded, there are still many problems. Especially for wind power inverters, due to the harsh operating environment, the actual service life of wind power inverters is far lower than the designed service life, which not only increases the diff...
