Problems solved by technology
Usually, in the case of a large number of motor poles and a large number of parallel circuits, this structure will be inconvenient to operate in production, and it is difficult to ensure the withstand voltage breakdown distance between the parallel rings of each phase
In addition, the firmness of this binding structure is mainly achieved by hardening the glass wire rope after the motor is dipped in paint, so that the firmness of the parallel ring in the operation of the motor is not high.

A kind of large-medium high-voltage motor paralleling ring binding structure relates to motor stator loop end paralleling ring binding structure, the loop end is banded with angle steel, thereinto, one end of said angle steel extends out of motor draught ring, one end is fixed with stator, angle steel extends out of draught ring is connected with bakelite rack, the upper and lower side of the bakelite rack separately possesses groove which is used to install paralleling ring. Benefit effects of the invention are: angle steel is fixed to stator clamping ring, then the another end is fixed with bakelite rack, and then paralleling ring is fixed to groove of bakelite rack, so distance of paralleling ring is increased greatly, it is easy to install, resistance to pressure is increased, and installation of paralleling ring is more reliable.
Description
technical field [0001] The invention relates to a binding and fixing structure of parallel rings at the ends of motor stator coils, in particular to a binding structure of parallel rings of large and medium-sized high-voltage motors. Background technique [0002] At present, the installation forms of the parallel rings at the ends of the stator coils of large and medium-sized motors mostly adopt small bakelite blocks to be placed between the parallel rings, and then tied with glass silk ropes. Usually, in the case of a large number of motor poles and a large number of parallel circuits, this structure will be inconvenient to operate in production, and it is difficult to ensure the withstand voltage breakdown distance between the parallel rings of each phase. In addition, the firmness of this binding structure is mainly achieved by the hardened glass wire rope after the motor is dipped in paint, so that the firmness of the parallel ring in the operation of the motor is not hi...
