Collector ring is the core component of generator self-parallel static excitation, and its reliability is crucial to the safe and stable operation of the whole generator set.
In recent years, more and more thermal power units take up the functions of grid peak shifting, frequency regulation, voltage regulation and standby, which has a greater impact on the reliability of the collector ring device.
The collector ring device is a structure that conducts the excitation current into the generator rotor and thus forms the excitation circuit by means of brush holders, brushes, slip rings, conductive screws and other structures.
Application field:
Since the establishment of the company, it has successfully manufactured 300MW-class hydro-hydrogen-cooled generators, full series of double-water generators, full series of air-cooled generators, 600MW-class hydro-hydrogen-cooled, 1000MW-class hydro-hydrogen-cooled generator collector ring devices, brush holders and brush grips, etc., and has provided the matching supply of brushes, and has become an excellent supplier and an exempted supplier of Shanghai Electric Generator Factory and Siemens, etc., which are the generator manufacturing enterprises.
Product performance:
In recent years, we have produced 605 sets of collector ring devices and 437 sets of brush holders for Shanghai Electric and Siemens. The company also actively invests in theoretical calculations and prototype tests, so that the product development cycle, product performance and product reliability have been continuously improved, and can fully respond to the user's personalised customisation needs and rapid service needs.
