大家好..小弟現(xiàn)有個問題求救啊.直流槍鉆得充電器輸出線拉力測試拉了一大截,充電器是二類得,看標準不是很懂.希望大家指導下.謝謝.
ul1310上說: 41.1 With internal connections disconnected, the strain relief means provided for a supply cord, or a
multi-conductor output cord where the interconnection of outputs exceeds Class 2 shall withstand the
force described in 41.3 applied to the cord for 1 minute without displacement or breakage of the cord or
deformation of its anchoring surface.
41.2 The output wiring of a unit other than one having a multi-conductor cord as specified in 41.1 shall
withstand the force described in 41.4 applied for 1 minute. The results are considered acceptable if, with
the output wiring connected internally, movement of the cord does not result in:
a) A reduction of spacings to primary or dead metal parts;
b) Damage to the transformer or enclosure; or
c) Interruption of the output wiring.
41.3 A 35 lbf (156 N) force is to be suspended from the cord and supported by the unit so that the strain
relief means is stressed from the most severe angle that the construction of the unit permits.
41.4 For units employing a flexible output cord, or a multi-conductor cord where the interconnection of
outputs does not exceed Class 2, a 20 pounds-force (89 N) is to be applied to the cord and supported by
the unit so that the strain relief means is stressed from the most severe angle that the construction of the
unit permits. For units employing output wiring consisting of separate leads, a 10 pounds-force (44 N) is
to be applied to each lead.
我得充電器適用哪章?還有第一章里說得multi-conductor output cord和interconnection of outputs exceeds Class 2是什么意思?能舉個例子嗎?謝謝.
