Abstract
The utility model relates to a mosaic rotor lead structure used for a megawatt double-fed asynchronous wind driven generator. The mosaic rotor lead structure used for the megawatt double-fed asynchronous wind driven generator is composed of a rotating shaft, a rotor lead, a metal wedge, a wedge block, a fan, a check ring, a shaft sleeve, a bearing, a slot wedge, a dowel, a slip ring, dovetail grooves and a hole. The rotating shaft is provided with the dovetail groove, the rotor lead is embedded inside the dovetail groove, the wedge block is embedded inside the dovetail groove on the lower portion of the fan and fixed by the check ring, the shaft sleeve is sleeved on the rotating shaft, the bearing is arranged on the shaft sleeve, and the slip ring is arranged on the rotating shaft in reverse mode to be connected with the rotor lead. The mosaic rotor lead structure used for the megawatt double-fed asynchronous wind driven generator is connected with a binding post on the slip ring by adopting the method of a mosaic copper bar, connection is stable, operation is reliable, and a failure rate is low. Meanwhile, the problems that because of cable connection and conducting rod connection, mechanical strength is poor, the mosaic rotor lead structure is easy to wear, shaft hole scale division and conducting rod scale division are nonuniform, whole assembly quality is influenced are avoided, and meanwhile, the shortcomings that two conducting rod connection positions are arranged inside a shaft hole so that workers can not detect whether connection is reliable easily and connection points are excessive so as to cause potential quality hazard and the like are overcome.
Description
Technical field: the utility model relates to the inserted rotor leading wire structure that a kind of MW class dual-feed asynchronous wind power generator is used.
Background technology: dual-feed asynchronous wind power generator adopts the phase-wound rotor coil, and rotor coil lead wire axial direction is connected this specific structure through bearing with slip ring; One of manufacturing difficult point that has determined double feedback electric engine is the version of rotor lead wire, and one of traditional structure is to adopt cable to connect, and its shortcoming is that cable is difficult for fixing in axis hole; The cable machinery intensity difference, easy abrasion, another kind of traditional structure is the form that adopts conducting rod to connect; Its shortcoming is that axis hole calibration and conducting rod calibration are uneven, influences whole assembly quality, and two body conducting rod junctions are in axis hole; Whether reliable, and tie point is too much, has hidden danger of quality if being difficult for detecting connection.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; The inserted rotor leading wire structure that provides a kind of MW class dual-feed asynchronous wind power generator to use, it has mainly solved the connection of employing cable, and cable is difficult for fixing in axis hole; Easy abrasion; The employing conducting rod connects, and axis hole calibration and conducting rod calibration are uneven, influence problems such as whole assembly quality.The purpose of the utility model be achieved in that inserted rotor leading wire structure that a kind of MW class dual-feed asynchronous wind power generator uses by: rotating shaft, rotor leading wire, metal wedge, voussoir, fan, back-up ring, axle sleeve, bearing, slot wedge, pin, slip ring, dovetail groove, hole constitute.Rotating shaft is provided with dovetail groove, and rotor leading wire adopts the copper bar form to be embedded in the dovetail groove, fixes through metal wedge, voussoir, slot wedge; Have the hole on the slot wedge, pin clenches through the hole, and voussoir is embedded in the dovetail groove of fan bottom; And fix with back-up ring; Axle sleeve is sleeved in the rotating shaft, and bearing is contained on the axle sleeve, and counter being contained in the rotating shaft of slip ring is connected with rotor leading wire.This product adopts the form of inlaying copper bar, and the copper bar that insulation is good is mounted in the surperficial dovetail groove that mills out of axle, and seals with metal wedge, slot wedge; Draw from the axle surface again, draw behind the copper bar bending with slip ring on binding post be connected, connect firm; Reliable, failure rate is low, has avoided cable to connect and has been connected with conducting rod; Bad mechanical strength, easy abrasion and axis hole calibration and conducting rod calibration are uneven, influence whole assembly quality; Two body conducting rod junctions are in axis hole, and whether be difficult for detecting connection reliable, and too much there are shortcomings such as hidden danger of quality in tie point.
