国内焊接铂铑——铂电偶之方法大致有三种:水银焊、电弧焊和气焊。此三种方法操作时都会产生一些有害气体,且操作复杂、效率低、成本高和工作不安全。我们研制了一种简易熔接器,其基本原理是:采用电热熔化焊接,熔接热电偶铂铑——铂偶合端点。自1980年实际应用以来,证明该熔接器结构简单(设备体积;180mm×160mm×120mm)、操作方便、成本低廉(每台50元左右)并采用安全电压,维修费省。 Domestic welding platinum and rhodium - Platinum couple methods are roughly three: mercury welding, arc welding and gas welding. These three methods produce some harmful gas when operating, and the operation is complicated, low efficiency, high cost and unsafe work. We developed a simple fusion device, the basic principle is: the use of electric fusion welding, welding thermocouple platinum rhodium - platinum coupling endpoint. Since its practical application in 1980, it has been proved that the fusion splicer has the advantages of simple structure (equipment size; 180mm × 160mm × 120mm), convenient operation, low cost (about 50 yuan each), safe voltage and maintenance cost.
