Abstract
The utility model relates to rotors, in particular to a motor rotor with a cable lead support, which solves the problem of fracture hidden danger and easiness in crushing a cable injured of a weftless tape caused by binding of a motor cable lead and a rotating shaft directly through the weftless tape. The motor rotor with the cable lead support comprises a rotating shaft, a cable lead, a three-phase winding lead wire and three connecting boards used for fixing the cable lead and the winding lead wire. A supporting cylinder is sleeved on the rotating shaft, three groups of lead locating combinations are evenly distributed on the supporting cylinder along the circumferential direction, and each lead locating combination comprises at least one countersink evenly distributed in the circumferential direction of the supporting cylinder and a groove located at one ends of all the contersinks and on the supporting cylinder. The motor rotor with the cable lead support is simple in structure, ingenious in design and capable of being widely applied to all double-fed wind driven generators or winding type asynchronous generators.
Description
Technical field
The utility model relates to rotor, is specially a kind of rotor that cable tail supports that has.
Background technology
Mostly double-fed wind power generator rotor winding three-phase lead-out wire is cable tail, and mostly through being connected with slip ring behind the axis hole, the cable tail that also has is along the arrangement of rotating shaft excircle, is connected with slip ring after passing bearing.Every phase lead-out wire of rotor winding three-phase lead-out wire can be made up of single, two, three or more cable according to the watt level difference; After welding together, winding lead wire and cable tail be fixed on the connecting plate; Divide three groups of excircles along rotating shaft to arrange, direct usually and rotating shaft is fixed together through no latitude band.There is following drawback in this structure: after the colligation of no latitude band, and irregularly shaped because of the rotating shaft excircle, binding strap also appears irregular, concavo-convex inequality, no latitude has unsettled phenomenon, has fracture hidden danger; Cable tail has directly and rotating shaft step seamed edge contact phenomena, if processing is bad, will squeezes and hinder cable insulation, can cause earth fault to take place.
Summary of the invention
The utility model causes existing no latitude band fracture hidden danger and squeezes the problem of hindering cable easily because of directly binding through no latitude band with rotating shaft in order to solve the motor cable lead-in wire, and a kind of rotor that cable tail supports that has is provided.
The utility model is to adopt following technical scheme to realize: a kind ofly have a rotor that cable tail supports, comprise the connecting plate of rotating shaft, cable tail, three phase winding lead wires and three attached cable lead-in wires and winding lead wire; Be with support cylinder in the rotating shaft, support cylinder along the circumferential direction is evenly equipped with three groups of lead-in wire location combinations, and the combination of lead-in wire location comprises at least one counterbore that is distributed in the support cylinder circumferencial direction and is positioned at all counterbore one ends and is positioned at the groove on the support cylinder.During use; Place respectively in each counterbore of three groups of cable tails location combinations after cable tail and three phase winding lead wires are welded together; The connecting plate that is fixed with cable tail and winding lead wire places cable tail location all counterbore one ends of combination and is positioned at the groove on the support cylinder; Then above the groove of support cylinder with the colligation of no latitude band, there have the place of cable tail to place in the groove on the support cylinder to be dented and do not have the local protruding of cable tail, and do not have the latitude band so unsettled phenomenon just can not occur; Increase no latitude band colligation reliability, eliminated fracture hidden danger; Support cylinder can prevent that cable tail from contacting with rotating shaft step seamed edge simultaneously, can not squeeze and hinder cable, has prevented the generation of earth fault.
The utility model is simple in structure, design is ingenious; Solved the rotor cable tail and caused existing no latitude band fracture hidden danger and squeeze the problem of hindering cable easily because of directly binding through no latitude band with rotating shaft, can be adaptable across all double-fed wind power generators or Wound-rotor asynchronous generator.

Embodiment
A kind ofly have a rotor that cable tail supports, comprise the connecting plate 4 of rotating shaft 1, cable tail 2, three phase winding lead wires 3 and three attached cable lead-in wires 2 and winding lead wire 3; Be with support cylinder 5 in the rotating shaft 1; Support cylinder 5 along the circumferential direction is evenly equipped with three groups of lead-in wire location combinations, and the combination of lead-in wire location comprises at least one counterbore 6 that is distributed in support cylinder 5 circumferencial directions and is positioned at all counterbore 6 one ends and is positioned at the groove 7 on the support cylinder 5.
During practical implementation, every phase winding of rotor three-phase winding lead wire lead-in wire is made up of single, two, three or more cable according to the watt level difference, and the quantity of counterbore was adjusted according to the difference of cable radical during made up every group of lead-in wire location.As shown in Figure 3, the winding lead wire is made up of three cables, then is provided with 3 counterbores in every group of lead-in wire location combination.
