国产JP-1,JP-1A,SJP-1型等示波极谱仪,由于具有分辨力强、灵敏度较高、测定快速等特点,已成为化验室常用的分析仪器,在生产和科研中发挥了重要作用。但是,这类仪器在使用中经常遇到B_4电源变压器跳火、击穿烧坏等故障,特别是潮湿、阴雨季节最易发生。由于B_4绕组较多,绕制工艺要求较高,因此,一旦B_4变压器烧坏,重绕麻烦,并且浪费人力 Domestic manufacturers of JP-1, JP-1A, SJP-1 and other oscillopolarographic instruments have become the analytical instruments commonly used in laboratories because of their strong resolving power, high sensitivity and rapid determination. They are used in production and scientific research An important role. However, such instruments are often encountered in the use of B_4 power transformer flashover, breakdown burnout and other failures, especially wet, rainy season is most likely to occur. As B_4 windings, winding process requires a higher, so once the B_4 transformer burned, re-trouble, and a waste of manpower
