早期生产的截流继电器衔铁上都带有一条粗软的分流导线,随着科学技术的进步被取消了。如我厂生产的FT81系列调节器的截流继电器上的这根粗软导线经过研究、试验,随着结构设计的改进已取消多年。对于这一分流导线我厂曾经历了省略→复原→再省略这样一个反复的过程,从中得到了教益和提高。早年我们曾用同样截面的导电铜片代替这根分流导线,型式试验情况良好,但在产品长期使用后,衔铁 Early closure of the relay armature produced with a soft shunt wire, with the progress of science and technology was canceled. Such as the factory production of FT81 series regulator of the closure of the relay on the thick and soft wire after research, testing, with the structural design improvements have been canceled for many years. For this diversion of wire I plant has gone through the omission → recovery → and then omit such an iterative process, from which the lessons learned and improved. In the early years, we used the same cross-section of the conductive copper instead of the shunt wire, the type test is good, but after long-term use of the product, the armature
