Description

technical field [0001] The invention relates to a combined control cabinet of a double-fed wind power generator, in particular to a combined control cabinet of a 1.5MW high-power double-fed wind power generator. Background technique [0002] The control cabinet is the pivotal equipment between the wind turbine and the AC power grid, and is the key equipment for regulating the working state and operating parameters of the wind turbine. At present, most of the control cabinets used for wind turbines are assembled sporadically , not only difficult to assemble and maintain, but also easy to generate frequency interference between each array component, especially in high-power double-fed wind turbines, this frequency interference may even affect the normal operation of the wind turbine. Contents of the invention [0003] The purpose of the present invention is to provide a new control cabinet for the assembly and maintenance difficulties existing in the current high-power doubl...
