IEC 61992-3-2001
摘要:
This part of IEC 61992 specifies requirements for d.c. disconnectors, switch disconnectors and earthing switches for use in indoor fixed installations of traction systems. NOTE 1 Switchgear assemblies, electromagnetic compatibility (EMC) and dependability are not covered in this part of IEC 61992, but rather by other parts of this standard or other standards as indicated in IEC 61992-1. NOTE 2 In this standard, the word "unit" means "disconnector and/or switch disconnector and/or earthing switch" as defined in 3.1.4, 3.1.5 and 3.1.6 of IEC 61992-1. NOTE 3 Disconnectors, switch disconnectors and earthing switches may have electrically latched mechanisms and, in such cases, may be indicated with the current term of "power contactors".
