Abstract
The utility model discloses a damping system of a nuclear power 1E grade emergency diesel oil generator rotor. The damping system comprises a pair of damping rings which are respectively mounted at two ends of a rotor iron core and multiple damping rods which are distributed at an outer surface of the rotor core and are connected between the pair of damping rings, wherein the damping rings comprise steel loops and copper rings connected on inner end faces of the steel loops, an outer diameter of the copper ring is greater than an outer diameter of the steel loop, and head portions of the multiple damping rods are welded at outer circular faces of the copper rings. The damping system of the nuclear power 1E grade emergency diesel oil generator rotor avoids loosing among damping components, guarantees connection reliability of the damping rods and the damping rings and reduces welding difficulty, additionally, the copper rings with high conductivity are employed as the damping rings to reduce damping resistance, so heat generated by a damping winding is reduced when a generator runs with a fault.

Technical field
The utility model relates to a kind of damping system of nuclear power 1 E-level emergency diesel dynamo rotor.
Background technology
Existing nuclear power 1 E-level emergency diesel dynamo rotor is that the hidden pole type punching laminates rotor, and the mode that the rotor damping system of this structure is welded by damper rod and trim ring unshakable in one's determination (damping ring) forms, and this mode has following some deficiency:
1. the material of trim ring unshakable in one's determination is steel, and the material of damper rod is copper rod, and the welding more complicated between different material (copper, iron), and welding quality is difficult to ensure card can't guarantee the reliability that is connected between damper rod and damping ring;
2. when the generator suddenly-applied short circuit, with producing larger damping current, if damping ring is steel plate, heating can be more serious, and is unfavorable to rotor body.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of damping system of nuclear power 1 E-level emergency diesel dynamo rotor to be provided, and it has solved the hidden pole type punching and has laminated that in rotor, damping system connects the problems such as insecure, that heating is serious.
The technical scheme that realizes above-mentioned purpose is: a kind of damping system of nuclear power 1 E-level emergency diesel dynamo rotor, comprise on a pair of damping ring that is arranged on respectively rotor core two ends and many outer surfaces that are distributed in rotor core and be connected to damper rod between a pair of damping ring, wherein, described damping ring comprises steel ring and is connected to copper ring on the inner face of steel ring, the external diameter of this copper ring is welded on the periphery of described copper ring the head of many damper rods greater than the external diameter of described steel ring.
The damping system of above-mentioned nuclear power 1 E-level emergency diesel dynamo rotor, wherein, give prominence to coaxially a small circle ring on the inner face of described steel ring, the height of this small circle ring and the height of described copper ring are adaptive, the external diameter of this small circle ring and the internal diameter of described copper ring are adaptive, and described copper ring is enclosed within on the small circle ring of described steel ring.
The damping system of above-mentioned nuclear power 1 E-level emergency diesel dynamo rotor, wherein, on the end face of described steel ring and uniformly accordingly respectively on the end face of described copper ring offer some through holes, so that described steel ring, described copper ring and rotor core link into an integrated entity by screw rod.
The technical scheme of the damping system of nuclear power 1 E-level emergency diesel dynamo rotor of the present utility model, the structure that the employing copper ring combines with steel ring is as the trim ring unshakable in one's determination of rotor, and utilize copper ring as the damping ring of damping system, make welding performance between damper rod (copper bar) and damping ring (copper ring) be better than welding performance between copper and steel, avoided becoming flexible between damping member, guarantee the reliability that damper rod is connected with damping ring, reduced the welding difficulty; Secondly, owing to adopting the high copper ring of conductance as damping ring, can reduce damping resistance, make generator when failure operation, the damping winding heating reduces, and is favourable to whole rotor body; In addition, damping system of the present utility model can also reduce axial dimension unshakable in one's determination, makes more reasonable structure, the compactness of motor.
