1.引言 温度保险丝是一种用于电器设备中作过热保护的感温保险丝。日本早在1970年就开始生产投入使用,国内湖北省洪源市晶体管厂八十年代初首家开始生产,目前已成为我国生产这种保险丝的主要厂家。温度保险丝是一种非可逆器件,它的最重要的一个参数就是熔断点温度,并且只能通过抽样的破坏性检测才能最终确定其合格率。检测的结果直接关系到成千上万支产品的命运,直接影响到生产厂家与用户的经济效益。为此我们为该厂研制了国内第一台温度保险丝(又可称限温熔断器)参数自动测试仪、该仪器在测试车间投入使用,使该厂产品检验发生了“质”的飞跃,收到了显著的效益。
1. INTRODUCTION A thermal fuse is a thermal fuse used for thermal protection in electrical equipment. Japan began production and put into use as early as 1970, the first domestic production of the transistor plant in Hongyuan City, Hubei Province in the early eighties, has now become China’s major manufacturers of such fuses. A temperature fuse is a nonreversible device whose one of the most important parameters is the melting point temperature, which can only be determined by the destructive testing of the sample in order to finalize the pass rate. The test results are directly related to the fate of thousands of products, a direct impact on the economic benefits of manufacturers and users. To this end, we have developed the first automatic temperature tester (also called temperature-limiting fuse) parameter automatic tester for this factory in China. The instrument was put into use in the test workshop, which made the quality inspection of the factory produce a leap. To significant benefits.
