Methods and means of state control of compression of stator core powerful turbogenerators

Abstract

The monograph is devoted to the development of new and improvement of existing methods and means of control of the stator core of powerful turbine generators (TG), which is one of the main components of machines and whose technical condition affects the technical characteristics and performance of machines. The topicality of the work determined by the growing requirements for information and measurement systems for monitoring and diagnostics of powerful TG to ensure their reliable and trouble-free operation. Shown that the main features of powerful TG, which determine the choice of technology to provide elastic compression of the stator core, are the method of collecting the core, the method of combining the core in the stator housing, the design of the end zone of the stator core and the cooling system. The main factors of reducing the degree of compression of the core, which include technological, operational and structural analyzed.
