Excitation technology rectifier components for 30-1350MW steam turbine generators
Date:2022.02.11 Views:893

At present, our main products are the series of brushless excitation and rectifier components for 30-1350MW steam turbine generators. Brushless excitation technology is widely used in generators and motors, especially large generators. Because the rectifier assembly is fixed with the exciter rotor of the unit and rotates synchronously, eliminating the need for commutators, slip rings and carbon brushes, it has the incomparable advantages of brush excitation.


Your benefits:

- No maintenance of slip rings and carbon brushes, high reliability;
- There is no pollution of the motor coil caused by carbon powder and copper powder, and the insulation life is long;
- No friction sparks, suitable for operation in harsh environments.


Rotating Rectifiers


The rotating excitation rectifier assembly is composed of main components and parts such as rectifier, capacitor, fuse, radiator and conductive parts, insulating parts and fasteners. It has the advantages of small size, strong function and high technical content. It is a functional component integrating heat, power and electricity. Based on the special structure of the rotating excitation rectifier components and the harsh operating environment, the company has established a complete quality management system. There are strict management and inspections from material selection, component selection, outsourcing parts inspection to processing technology, installation technology and testing. Thereby ensuring that the company's products fully meet the technical requirements of customers, long-term and reliable operation.
