真空吸尘器非正常运行的泄漏电流测试修订日期修订单号修订内容摘要页次 版次修订审核批准2011/03/30/系统文件新制定2A/0///批准：审核：编制：真空吸尘器非正常运行的泄漏电流测试1.0 Purpose / 目的To evaluate if the sample under abnormal operation conditions can comply with the safety requirements about leakage current in UL1017评估样机在非正常运行状况下的泄漏电流是否符合 U L1017 的泄漏电流要求.2.0 Definition/概念:2.1 Leakage current limits(泄漏电流限制): Not more than 5.0 MIU for an ungrounded, 2-wire, portable sample; 对不接地的 2 线制便携式器具,不超过 5 MIU Not more than 5.0 MIU for a grounded, 3-wire, portable sample对接地 3 线制便携式器具,不超过 5 MIU.2.2 Clear airflow ---The air through the filter into motor wanes. 干净进气 --- 进气经过 Filter 后, 再经过 motor 风叶, 此类吸尘器为干净进气.2.3 Dirty airflow --- the air directly into motor vanes then through the filter. 脏的进气 --- 进气直接经过 motor 风叶 (或者水经过马达风叶)后再经过 Filter, 此类吸尘器为脏的进气2.4 Leakage current --- All currents measured between the (dead-metal parts)/(metal foil with an area of 10 by 20 cm in contact with the thermoplastic surfaces of the sample) and the grounded side of the supply source. See figure1&2. 泄漏电流 --- 从不带电金属零部件/马达壳表面和地线之间测得的电流.3.0 Reference Documents/参考文献:U.L.1017 CAN/CSA-C22.2 NO.243-01, dated 12-7-2001,CL 5.54.0 Equipment/设备:4.1 Frequency converter. (变频电源)4.2 Leakage current tester(泄漏测试仪)4.3 Stop watch(秒表)4.4 Leakage test switching box (made per the circuit shown in Figure 2) 泄漏测试盒(按图 2 原理制作)5.0 General Instructions/说明:5.1 Tests may be conducted at any ambient temperature within a range of 10-40 (50-100).℃℉测试可在 10-40(50-100)℃℉ 之内的环境温度下进行.5.2 Unless otherwise noted, all tests are to be conducted with...
