The utility model has the advantages of ensuring the locking of the radial conducting screw bolt and guaranteeing the reliably electrical connection of generator rotor excitation circuit.
Description
Technical field
The utility model relates to radially conductive lever locking mechanism of a kind of generator amature, can be used for having the generator amature of radial/axial pin configuration, belongs to the critical component of generator amature energized circuit, belongs to the generator amature technical field.
Background technology
Generator is that stator and rotor are formed by the two big basic elements of character.Thereby the rotor-exciting loop of giving high speed rotating loads direct current and forms rotating magnetic field, stator winding induces three-phase alternating current and flows to electrical network, guaranteeing effective connection in rotor-exciting loop, avoid open circuit to lose and encourage the phenomenon generation, is to guarantee the requisite prerequisite of generator safe and reliable operation.
Present radially conductive lever locking mechanism, as shown in Figure 1, radially conductive lever 6 tops have top cover 1, and it is fixing that lead-in wire 4 passes through nut 5 for 1 time at top cover, radially conductive lever 6 upwards screws nut 5 with specific purpose tool at last with the Whitworth thread hole on certain moment requirement screw-in axle 2 lead-in wires.
When 300MW, 600MW generator outage check, find to have that nut 5 on the part rotor radial conductive lever is loosening causes the open circuit phenomenon, the hidden danger that has an accident is arranged.
Summary of the invention
The purpose of this utility model provides a kind of radially conductive lever locking of guaranteeing, guarantees that the generator amature energized circuit is electrically connected radially conductive lever locking mechanism of reliable generator amature.
For realizing above purpose, the technical solution of the utility model provides radially conductive lever locking mechanism of a kind of generator amature, comprise rotor, J lead-in wire, nut, conductive lever radially, it is characterized in that, conductive lever screw top attaching nut radially, the J lead-in wire is located at the nut below, and the nut thread below the J lead-in wire is connected and fixed, and is provided with cross-over block between nut and rotor.
Described radially conductive lever top is a straight-bar shape, and described two nuts and nut are the pick copper nut, and external diameter equates that two nuts are provided with V-type grooved ring v notch v respectively near J lead-in wire contact-making surface place.
The utility model radially conductive lever changes straight-bar shape into, by two identical pick copper nuts of external diameter the J lead-in wire is fixed, and connects reliable, can not become flexible, radially the conductive lever thread connection has auto-lock function, increases cross-over block, both can support preface 5 nuts, can increase creepage distance again.
The utility model has the advantages that and guarantee radially conductive lever locking that it is reliable to guarantee that the generator amature energized circuit is electrically connected.
