Rectifier Assemblies for Rotating Exciter in Generators
Introduction
Our advantage is Rectifier Assemblies for Rotating Exciter in 10~1350MW generator. The brushless excitation technology can be widely used for synchronous generator and electromotor, especially large generator. Due to the close integration of rectifier assemblies and exciter rotor, they are synchronous rotating without the commutator, slip-ring and carbon brush, the maintenance intensity and the impact of carbon powder on the environment can be reduced, which are better than static excitation.
Rectifier assemblies for rotating exciter is composed of rectifier, capacitor, fuse, heat sink, conductive parts, insulation component, fastener etc.. It is a high-tech product which integrates the function of absorption-protection, electric conduction, heat diffusion.
Features
·High reliability, no required maintenance for slip-ring and carbon brush.
·Long insulation life, no pollution on generator field coil caused by carbon powder
and copper powder.
·Suitable for working in harsh environment, no friction spark, such as explosion-proof.
Rotating Rectifying Disc for Synchronous Electromotor
The rotating rectifying disc is the core of the brushless excitation synchronous electromotor system, which can convert the AC generated from the AC exciter into DC power supply output by rectifier unit under the condition of high-speed rotation.
It is applied in the brushless excitation rotating rectification part of 10-100 MW synchronous motor, which can work safely and reliably for a long time under the condition of 1000-4800 RPM. The diameter of the disk body is 700mm, the thickness is 80mm. It also can be customized according to user requirements.
Rotating Rectifying Disc for Synchronous Generator
Introduction: GBX series rotating rectifying disc for generator are applied in the brushless excitation for 50-150MW air-cooled generator units.
Features: Compact structure, small size, easy installation and maintenance,stable performance.
The forward characteristics of the rectifier elements are good consistent.
Each unit constitutes an independent rectifier bridge arm and the required system can be flexibly assembled according to the needs.
