标准摘要
[中文适用范围]： 本国际标准规定了用于航空地面照明恒流串联电路的标称输出为 6@6 A 的恒流调节器 (CCR) 的要求。然而，@ CCR 的制造可能具有与本标准中指定的不同的额定功率 (kVA) 和电流步长，以便在现有电路上使用。本标准应适用于这些 CCR 的适当情况。 [外文原描述]： IEC 61822:2009 specifies the requirements for a Constant Current Regulator (CCR) having a nominal output of 6,6 A for use in an aeronautical ground lighting constant current series circuit. However, CCRs may be manufactured which have a different power rating (kVA) and current steps than those specified in this standard in order to be used on existing circuits. This standard should be applied where appropriate for these CCRs. This second edition cancels and replaces the first edition published in 2002. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision and update of terms and definitions; b) addition of new paragraphs, such as "Nominal output current range and tolerances"; c) modification of some paragraphs, such as those related to "Local control" and "Remote control"; d) deletion of some paragraphs, in particular "Power transformers" and "Output current indicator".
