Brief Introduction

 

As an important aux equipment of power plants, DC motors can ensure the reliability of the operation of each system during the shutdown and standby of the unit.Especially when DC motors such as steam and oil pumps fail, fault recording methods should be used as soon as possible to comprehensively check and analyze the control circuit and various components, and investigate the possible causes of motor failures one by one.At present, DC motors used in power plants, generally as the auxiliary equipment,  have unipolar resistance start-up conditions, and the start-up current is too large, which has a large impact on electrical components and mechanical components during start-up, which affects their life.

 

In addition, the general parallel excitation motor does not consider the design of under-excitation protection. During the no-load trial operation or light-load operation of the motor as a aux equipment, if the excitation circuit is open, it may cause serious consequences of the motor "speeding". Therefore, in the daily maintenance and maintenance, we should pay attention to the timely detection of hidden dangers in the equipment, and constantly improve the structure and process flow.
