Description
Technical field
The utility model relates to mechanism of power generation technology for making field, particularly the anti-rejection fixed structure of connecting line between a kind of novel rotor pole.
Background technology
Generator amature interpolar connecting line is the vitals in turbine-generator units, is the prerequisite of stable operation of unit, ensures that its fail safe is very necessary.Due to the restriction of the structure of rotor, between rotor pole, the fixed form of connecting line is all generally adopt wire clamp to fix, and is namely clamped by lead-in wire with two insulation boards, by the movement of clamping force restrict rotor lead-in wire.Because unit is in operation, must have fit-up gap between interpolar connecting line and wire clamp, interpolar connecting line vibration back and forth in wire clamp, cannot fix, and may cause the phenomenon broken because displacement is comparatively large.Traditional wire clamp fixed form can not ensure the distortion that interpolar connecting line produces under centrifugal action completely.Therefore a kind of novel and effective fixed form be must consider from new, the generation injurious deformation of interpolar connecting line and damage prevented, to guarantee the stable operation of unit.
Utility model content
The purpose of this utility model is to provide the anti-rejection fixed structure of connecting line between a kind of novel rotor pole.
The technical solution of the utility model is the anti-rejection fixed structure of connecting line between a kind of novel rotor pole, it is characterized in that: comprise bolt, locked spacer, pressing plate, upper insulation plate, expoxy glass stringing, lower insulation plate, parallels, rotor yoke pressing plate, interpolar connecting line, described locked spacer is positioned on the downside of the nut of bolt, described pressing plate is positioned at the below of locked spacer, described upper insulation plate is positioned at the below of pressing plate, described interpolar connecting line is positioned at the centre of upper insulation plate and lower insulation plate, the screw rod periphery that described bolt contacts with interpolar connecting line is overlapped and is had expoxy glass stringing, described lower insulation plate is positioned at the below of interpolar connecting line, described parallels is positioned at the downside of lower insulation plate, described parallels is processed with the screwed hole matched with bolt size, described bolt and parallels are closed by fixing of screwed hole, described parallels and rotor yoke pressing plate are fixedly linked.
Further, described parallels by welding mode and rotor yoke pressing plate be fixedly linked.
