IEC60335-1 里有这样一段话:
4 z! t* r% T# pWhen the glow-wire test of IEC 60695-2-11 is carried out, the temperatures are
: n9 A! |8 S5 I/ Y# M7 I– 750 °C, for connections which carry a current exceeding 0,2 A during normal operation;
8 r1 Y) }2 `+ c- q! X$ I– 650 °C, for other connections.* g3 ]: V9 u' \5 d
NOTE 1 Contacts in components such as switch contacts are considered to be connections.
9 y4 }& j: v- H. R% }& KNOTE 2 The tip of the glow-wire is applied to the part in the vicinity of the connection.6 G5 n! H* p7 y
这是有人照看的器具,无人照看类器具也有类似的注释.
; H; w6 t& ~1 @8 F, O0 S, O9 `我主要是问一下开关算不算是连接件呢?到底按750度 还是650度执行呢? |
