保险丝的分析.pptVIP

技术标准Technology Standard 中国CCC认证的覆盖面太小 CCC certification’s coverage is too small. GB9364.1/.2/.3-97实施八年需要及时修定, GB9364.4要尽快发布, GB9364.5/10要早日编制 GB9364.1/.2/.3-97 has been used for 8 years and need be revised. IEC standard has renewed greatly. GB9364.4 should be issued as soon as possible. GB9364.5/9/10 should keep up with the speed soon. 美规产品还没有技术标准 There are no GB standards for America seriese fuses 用户认知User Recognization 许多工程师对熔断器产品认识非常欠缺,对其功能和技术参数不甚了解,对小型熔断器与其他类似保护元件的特点差异不很清楚,在准确选用上存在一定困难和误解 There are difficulty and misunderstanding in fuse’s accurate selection for many engineers with little knowledge of fuses, who are unfamiliar with fuse’s function technology parameters, characteristics and difference between subminiature fuse and other similar protection components. 相当一部分工程人员对熔断器的保护功能及其必要性认识不足,在成本压力下往往随意采用达不到要求的低档产品甚至干脆取消不用,不利于行业健康发展; Many engineers without enough knowledge in fuse’s protection function and necessity, use arbitrarily unqualified low-quality fuses or even cancel fuse’s use, which goes against fuse’s healthy development. 全球化Globalization 地方/民族/国家保护意识限制了产品流通,不利于技术交流 Region/nationality/country’s protection consciousness limits product’s circulation, which goes against technology communication. 欧规和美规产品走向统一的进展步伐缓慢,迄今通用模件式小型熔断器(MFU)还只有个别品种 The development speed of Europe and American standard series of products’ unification is slow. Till now the universal mold fuse units (MFU) only are some special types. 本地化Localization 技术/管理优势缺少纵横向交流 Technology/administration advantage lacks transverse and vertical communication. 部分材料/技术/工艺/设备依靠进口 Parts of materials/technology/process/equipment rely on import. 管理层/技术业务骨干仍用外来人士 Administration/technology business key persons still come from foreign. 本地化问题值得引起重视 It is worthy to pay attention to localization 谢 谢 大 家 ! Thank you ! 19世纪80年代,爱迪生申请了第一个在电路中相当于安全阀门的保险丝专利,开启了熔断器发展的历史 保险丝应用日益广泛,产生了众多的设计,各行各业对保险丝有不同要求,由此产生了外形/尺寸/安装形式/材料/结构/规格/特性/
