我们在使用QC83系列防爆磁力启动器过程中,发现LX1型6A500V停止按钮在外力和按钮主弹簧力的相互作用下,按钮顶盖经常发生剪切损坏,使主弹簧弹出,磁力启动器不能正常工作。由于经常发生此类事故,以致值班电工都要随带几个停止按钮,以便更换。既费时间,更影响生产。为此、我们对LX1型停止按钮作了简单的改进,方法如下: 将停止按钮第一组常闭接点的弹簧,截去1.2圈后从第一个动接点片的后面移到它的前面,移放时原弹簧两边的红钢纸垫要舍去。将主弹簧从按钮顶盖后面移放到第一个动接点片后面,见下图:
We use QC83 series explosion-proof magnetic starter and found that LX1 6A500V stop button in the external force and the button main spring force interaction, the button cover often shear damage, so that the main spring pop-up, the magnetic starter can not work . Due to the frequent occurrence of such accidents, the electrician on duty is required to bring several stop buttons for replacement. Both time-consuming, but also affect the production. To this end, we made a simple improvement on the LX1 stop button, as follows: The stop button The spring of the first set of normally closed contacts, after removing 1.2 turns from the back of the first moving contact piece to its front, Reduce the original spring on both sides of the red steel paper pad to be discarded. Move the main spring behind the button cover to the back of the first moving contact, see the following figure:
