Hydraulic generator rotor lead wire fixed knot constructs

Technical Field

Background

The hydraulic generator is a generator which takes a hydraulic turbine as a prime mover to convert water energy into electric energy. When water flows through the water turbine, water energy is converted into mechanical energy, and a rotating shaft of the water turbine drives a rotor of the generator to convert the mechanical energy into electric energy for output. Is the main power equipment for generating electric energy in a hydropower station.

Some hydraulic generators can drill deep holes on a shaft due to the actual requirements of the structure, then lead out a rotor lead from the deep holes of the shaft and are connected with a collecting ring, and the structure that the rotor lead is led out from the deep holes is complex. The passing position of the lead is ensured to be smooth enough to prevent the lead from being damaged and causing electrical faults due to processing defects, and particularly for a motor with large rotor current, the diameter of the rotor lead is relatively large, and the lead mounting process is relatively difficult; another problem with this arrangement is that the fixing from the lead-out portion of the rotor winding to the portion penetrating into the deep hole is subject to more restrictions, both by ensuring that the lead is forced away from the conductor and by reducing the centrifugal force applied to the lead during rotation of the rotor.
