Abstract
The utility model relates to a rotor magnetic-pole coil copper-bar connection structure; a U-shaped connection copper bar is arranged between a leading-in end and a leading-out end of the magnetic pole of two adjacent rotor magnetic-pole coils in the same direction through a bolt and a nut; the U-shaped connection copper bar is fixed on the magnetic yoke of the rotor through a tightening element. The structure has the advantages that the reversibility of the current in the adjacent coils can be satisfied; the connection structure is not only convenient to be installed, and is applicable to the generator with different rotation speeds, but also the connection of the magnetic-pole coil is firm, and the operation is stable, thereby satisfying the mechanical strength requirement during the operation of the rotor, and preventing different safety problems caused by the throwing of the rotor for the connection wire of the magnetic-pole coil.
Description
Technical field
The utility model belongs to the hydraulic turbine and makes the field, particularly relates to a kind of simple in structure, easy for installation and rotor magnetic pole coil copper bar syndeton that fastening structure is safe and reliable.
Background technology
In the design of prior art hydraulic generator, being linked and packed between the rotor magnetic pole coil normally adopted following several structure: one, after 1 coiling of rotor magnetic pole coil is finished, connecting line is put and headgear 2, firm with soldering then, because also headgear and magnetic pole and yoke are unfixing, in running, be easy to bring very big economic loss to unit because of action of centrifugal force causes the also fracture of headgear.The connection (as shown in Figure 1) of the power generator rotor magnetic pole coil of low capacity low cruise during this fastening means is specially adapted to.Its two: after 1 coiling of rotor magnetic pole coil is finished, adopt brace 3 overlapping modes, brace is fixing with copper bar pull bar 4, and then pull bar is fixed on the yoke, and this kind fastening means is particularly useful for the connection (as shown in Figure 2) of the higher power generator rotor magnetic pole coil of rotating speed.Aforementioned two kinds of connected mode structure more complicated, when pole coil connecting line mode is selected improper or fastening when insecure, can cause the magnetic pole connecting line rotor that flies out, so not only can cause the major accident of rotor, but also can damage electricity generator stator coil and stator core, bring hidden danger for the operation of generating set.
Summary of the invention
The utility model provides a kind of fastening, easy for installation and safe and reliable rotor magnetic pole coil copper bar syndeton simple in structure for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: rotor magnetic pole coil copper bar syndeton, it is characterized in that: in the same way be connected with U-shaped with exit by screw bolt and nut at the magnetic pole leading-in end of two adjacent rotors pole coils and be connected copper bar, described U-shaped connects copper bar and is packed on the yoke of rotor by securing member.
The utility model can also adopt following technical scheme:
Described securing member adopts pressure plate structure.
Described securing member adopts the wire clamp structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly the leading-in end of two adjacent rotors pole coils adopts U-shaped to be connected the continuous in the same way invertibity that just can satisfy electric current in the adjacent windings of copper bar with exit, in tubular generator, can adopt pressing plate that the U-shaped copper bar is fixed on the yoke ring, adopting wire clamp that the U-shaped copper bar is fixed on the yoke in conventional generator gets final product, this kind syndeton is not only easy for installation, applicable to the generator of various rotating speeds; And pole coil connects fastening firmly, stable, satisfied the requirement of mechanical strength in the rotor operation, can avoid because of and headgear fracture back connecting line throw away the various hidden dangers that rotor causes.
