40、Introduction This introduction is not part of IEEE Std C37.82-2017, IEEE Standard for the Qualification of Switchgear Assemblies for Class 1E Applications in Nuclear Power Generating Stations. This standard complements IEEE Std 323-2003, IEEE Standard for Qualifying Class 1E Equipment for Nuclear Po
41、wer Generating Stations, by providing specific requirements for the qualification of switchgear assemblies for safety-related applications in Nuclear Power Generating Stations. 1This standard is typically used in combination with seismic qualification standards IEEE Std 344 and IEEE Std C37.81 to pe
42、rform a complete qualification program for switchgear assemblies. The primary purpose of this standard is to define the requirements that should take place prior to a seismic qualification program. Significant degradation could occur during the service life of switchgear assemblies; therefore it is
43、important that test samples be in a state of degradation prior to seismic event simulation. IEEE Std 323-2003 provides guidance for evaluating time based aging mechanisms caused by excessive ambient temperatures and /or a radiation environment. Safety-related switchgear assemblies are typically loca
44、ted in mild environments, and are not impacted by these time-based aging mechanisms. Circuit breakers and other switchgear components used in nuclear facilities may be subjected to frequent cycling through testing or routine plant operation. Therefore, a pre-seismic aging program that cycles circuit
45、 breakers and components through endurance testing is typically required. This standard considers that qualified life may be a time interval, operational cycles, or both, whereas IEEE-323-2003 defines qualified life as a time interval. Changes in this standard include adding definitions of Seismic C
46、ategory I and Seismic Category II equipment. Seismic Category I is equivalent to Class 1E. Seismic Category II is for equipment that is not required to function but whose failure could adversely affect the safe shutdown of any Seismic Category I equipment. In approaching the task of developing a sta
47、ndard for these procedures, the authors noted the following: a) Standards for switchgear assemblies have been developed over a long period of time through the efforts of the Institute of Electrical and Electronics Engineers (IEEE), the National Electrical Manufacturers Association (NEMA), and other
48、interested parties under the auspices of the American National Standards Institute (ANSI). b) The switchgear assembly products that have been produced in accordance with these standards and that have been properly manufactured, applied, handled, installed, operated, and maintained, have had long and
49、 successful performance records. c) Because switchgear assemblies are protective equipment, the standards are conservative and provide ample margin with respect to normal application. Design and application also tend to be conservative. d) The application of switchgear assemblies is always outside the containment in a nuclear power generating station. Normal service conditions are not severe. The only unusual requirements sometimes presented are as follows: 1) The need to meet safety-related performance demands during a design basis event (DBE) at any time, up to
