Impregnating resin applied to wind driven generator insulating vacuum pressure impregnating treatment and impregnating method

Abstract

The invention relates to an impregnating resin applied to wind driven generator insulating vacuum pressure impregnating treatment and a method for manufacturing a rotor winding and a stator winding of a wind driven generator made of the material. The impregnating resin applied to wind driven generator insulating vacuum pressure impregnating treatment is mixed by components A and B, wherein the components A and B are respectively packaged and separately stored; and in actual production, 100 weight parts of component A and 80 to 120 weight parts of components B are uniformly mixed so as to prepare the uniform and transparent faint yellow impregnating resin. The rotor winding or the stator winding of the wind driven generator is subjected to vacuum pressure impregnation by the impregnating resin and then is baked and cured, so that a mica tape layer around the rotor winding or the stator winding and an insulating layer of the impregnating resin are cured to form the rotor winding or the stator winding of the wind driven generator with insulating effect.

Description

technical field [0001] The invention relates to an impregnating resin suitable for vacuum pressure impregnation treatment of wind-driven generator insulation, and a manufacturing method of a wind-driven generator rotor and a stator winding made of the material. Background technique [0002] As a clean and environmentally friendly new energy source, wind energy has long been valued by countries all over the world. my country's wind power industry developed relatively late, but the speed of development is very fast. Since the establishment of the first wind farm in 1986, the national installed capacity of wind power has increased to 344MW by the end of 2000. According to the new energy development plan under study, according to resource conditions, regional development conditions and infrastructure conditions, etc., it is planned that by 2020, my country's wind power installed capacity will exceed 150 million kW. And according to the current development trend, it will definit...

Problems solved by technology

Although the impregnating resin containing styrene system has a lower volatilization in the production process and can participate in the curing reaction compared with the less-solvent paint, it still has the following disadvantages: 1. The vapor pressure of styrene and other substances is low and the toxicity is very high , a large amount of volatilization during the curing process will cause environmental pollution and endanger the health of the operator; 2. The cured product of this system can only meet the electrical performance standards. For wind turbine insulation, the insulating layer is relatively thin. Therefore, the safety factor is low; 3. The impregnated resin containing styrene-based reactive diluents, after baking and curing, forms an insulating layer together with the mica tape. The thermal mechanical strength is generally not high, and the ability to withstand environmental and climate influences is relatively poor. , poor reliability when applied to wind turbine rotor insulation
