Generator Conductive Screw

Conductive screws are fasteners in QFSN-300-2 generator sets that serve both mechanical fixation and conductive functions.

Functions of Conductive Screw

• Current transmission: Their primary function is to transmit current.
• Mechanical fixation: They also fix the rotor conductive rings to ensure the rotor rotates flexibly at high speeds.
• Anti-loosening ability: Their design often includes special anti-loosening structures.
• Conductive reliability: They are typically made of highly conductive materials like copper alloy.
• Sealing performance: In some generators, the outer insulating layer of the conductive screws has high dielectric strength and sealing performance.

Application of Conductive Screw

• Connection of rotor coil leads and conductive rods: Used to connect the rotor coil leads to the conductive rods.
• Fixation of rotor conductive rings: Used to fix the rotor conductive rings to ensure stability during high-speed rotation.
• Connection under the slip ring: Used under the rotor slip ring to connect the slip ring and the shaft.
• Generator rotors with radial/axial lead structures: Used to tighten the conductive threaded rods to ensure the stability of the excitation circuit.
