Problems solved by technology
Due to the large deformation and unevenness of the wire mesh, the steel wires of the wire mesh are easy to burn out during welding
After a long time of operation, the ventilation screen of the motor is prone to deformation, the welding is not firm, and the solder joints are easily damaged, resulting in an unsightly appearance; with the requirements of customers for the beautiful appearance of the motor ventilation screen, the shape of the original screen has been changed. Can not meet customer requirements

Embodiment Construction
[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0012] like Figure 1 to Figure 2 As shown, it includes a stamped mesh panel 1, a ring rib 2 and a frame rib 3.
[0013] The punched net plate 1 is punched from a steel plate with a thickness of 2 mm, and some ventilation holes are punched on it as required for ventilation; the punched net plate 1 is welded with a ring-shaped reinforcement collapse 2 and a cross reinforcement tendons3. The cross reinforcement 3 is made of a cross reinforcement steel plate with a thickness of 5mm and a height of 25mm. The annular reinforcing rib 2 is made of reinforced steel plate, the thickness of which is 5mm, and the height is 25mm.
[0014] The ventilating net plate of the motor of the present invention is not easy to be deformed after long-term operation, and has an unattractive appearance; it can meet the requirements of customers for the beautiful appearance of the ven...

The invention relates to a structure of a ventilation screen plate of a high-voltage three-phase asynchronous motor, which is in particular applied to high-voltage high-efficiency motor YKK630-6-1500KW10000V motors. The structure of the ventilation screen plate comprises a punching screen plate, annular reinforcing ribs and cross reinforcing ribs, wherein the punching screen plate is welded with the annular reinforcing ribs and the cross reinforcing ribs. Vent holes are punched on the punching screen plate and are used for ventilating. The ventilation screen plate disclosed by the invention has the advantages of simple and reasonable structure, convenience for operation, attractive appearance, low cost, good manufacturability, high reliability, and convenience for mounting, use and maintenance; after a screen plate runs for a long time, deformation is unlikely to generate; and the structure of the ventilation screen plate can be widely applied to motors in the fields of industry, agriculture, commerce, building industry, traffic and the like.
Description
technical field [0001] The invention relates to a ventilation screen structure of a high-voltage three-phase asynchronous motor, specifically used in a high-voltage high-efficiency motor YKK630-6-1500KW 10000V motor. Background technique [0002] In the prior art, the ventilation screen structure of the traditional motor is composed of a steel wire mesh and a ring-shaped cover plate, and the steel wire mesh and the ring-shaped cover plate are welded by electric spot welding. Due to the large deformation and unevenness of the steel wire mesh, the steel wires of the steel wire mesh are easy to burn out during welding. After a long time of operation, the ventilation screen of the motor is prone to deformation, the welding is not firm, and the solder joints are easily damaged, resulting in an unattractive appearance. With the requirements of customers for the beautiful appearance of the motor ventilation screen, the original screen shape has been changed. Can not meet customer ...
