Technical Field

The utility model relates to a generator field, in particular to generator rotor tip insulation mount.

Background

The generator is mainly composed of a stator, a rotor, an end cover, an electric brush, a base, a bearing and the like. Wherein the rotor is an important part. As shown in fig. 1 and 2, the rotor is composed of a rotor core S1, a rotor winding S2, a rotating shaft S3 and the like, the rotor core S1 is sleeved outside the rotating shaft S3, and the rotor winding S2 is formed by winding copper wires in winding slots S11 on the rotor core S1. When the generator works, the rotor needs to rotate at a high speed, and the rotor winding S2 wound on the two ends of the rotor is easy to loosen or separate under the high-speed and long-time rotation without a fixing device, so that potential safety hazards exist. In addition, the end of the rotor needs to be provided with leads and wiring, and the rotor winding S2 wound on the two ends of the rotor is also not provided with an insulating device, so that the rotor is likely to be short-circuited at high-speed and long-time rotation, and potential safety hazards exist. Therefore, it is necessary to design a generator rotor wire-off prevention device to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The technical scheme of the utility model is realized like this:

generator rotor tip insulation mount, including insulating fixed part and the installation fixed part of connection terminal surface under insulating fixed part, insulating fixed part includes the connecting plate and connects the anticreep insulation board at the connecting plate both ends, and the installation fixed part is two fixed picture pegs and inserts one or two kinds in the post, and two fixed picture pegs are used for inserting the wire winding groove on the generator rotor core and reach the fixed action, insert the post and be used for inserting the jack on the generator rotor core and reach the fixed action.

Further, the connecting plate is one piece or two pieces.

Furthermore, the number of the inserting columns is one or two.

Furthermore, the outer end angle of the connecting plate is an arc angle.

Further, the anti-dropping insulating plate is a sector plate.

The utility model has the advantages that: the utility model discloses install at the both ends of generator rotor core, play anticreep, fixed and insulating effect to the rotor winding, prevent that the generator from taking place short circuit and trouble, improve the security performance.
