求能购买到温升设备和校准熔丝的国内厂家。作者: jqtimo 时间: 2012-2-4 14:19
12.2 的倒角应保括接地作者: 月色浪漫 时间: 2012-2-4 14:20
12.2 两个倒角斜度,即58~62度和60~80度,对接地与载流插销都适用作者: xekbhm 时间: 2012-2-4 14:20
一,10章,接地措施:
BS1363-1我个人理解是:条款上并没说测最远还是最近端,而是强调连接在一起的接地金属件 的电阻不超过0.05欧姆。
二,11章,端子和端头:6BA的英式螺纹是英制电器螺纹,钻孔直径为2.4到2.5mm。
三,12章,插头结构:58~62度和60~80度的倒角对接地,L,N极均适用。
四,16章,温升设备:现在网络这么发达,在网上搜搜有很多。作者: dotzuv 时间: 2012-2-4 14:20

一,10章,接地措施:
b) for metal parts connected to an earthing terminal or earthing plug pin, by the following test.
A current of 25 A ± 0.75 A, derived from an a.c. source having a no-load voltage not exceeding 12 V, is passed for s between the remote end of the protective conductor of a 3-core flexible cord (cut to a length of 150 mm ± 5 mm measured from the nearest edge of the earthing pin) and the remote end of the earthing plug pin and any accessible metal part intended to be earthed,
b)项总要求是连接到接地端子或接地插销的金属部件,但中间在描述过程中出现了“150mm三芯软线的最远端”,是否需要测量?如果象国标或IEC测量,根本就不会涉及到接地导线。
二,11章,端子和端头:6BA的英式螺纹是英制电器螺纹,钻孔直径为2.4到2.5mm。
测量时如何进行呢?测量螺纹孔的内径吗?在2.4~2.5之间?
我觉得标准条款是讲端子螺钉,没涉及到螺纹孔。
Terminal screws shall have a declared outside diameter of not less than 3 mm or be not smaller than 6 B.A.作者: 622 时间: 2012-2-4 14:20
最远端?翻译有问题吧。
就是地线pin到150mm导线处的电阻不超过0.05欧姆。
6BA你可以查BS93-2008,外径大约是2.8mm作者: dotzuv 时间: 2012-2-4 14:20
12.5 In non-rewirable plugs, where the fuse link is retained by means of a fuse carrier, this device shall be either:
a) non-detachable during normal replacement of the fuse link; or
b) readily identifiable in relation to its plug by means of marking.
