随着自行车生产发展,我厂车架盐浴浸焊炉的低压变压器已经用到3400仟伏安。(60年代初用伏安。)大容量变压器在使用中。出现了一个新的问题,即控制焊接温度变压器起仃频繁,每仃一次驾起动时,1200仟伏安供电变压器要跳1至2次闸,直接影响了生产,并且在起动时供电变压器会产生很大的电动力与异声,而供电变压器输出的1000安培自动空气开关过流保护的镇定值也与已选到3000安培,又介决跳闸问题克服冲击电 With the development of bicycle production, low-voltage transformers for frame salt bath dip soldering furnaces of our factory have already used 3,400 kVA. (Voltammetry in the early 60’s) Large-capacity transformers in use. A new problem has arisen in that the control of the welding temperature transformer is frequent and each time a trip is started, the 1200 kVA power supply transformer trips 1 to 2 times, directly affecting the production and the power transformer is generated at start-up Great electromotive force and noise, while the supply transformer output of 1000 amperes automatic air switch over-current protection of the ballast also has been selected to 3000 amperes, and the issue of tripping overcoming the impact of impulse
