摘要
介绍了塑料外壳式断路器(MCCB)的脱扣原理及校验方法,详述了MCCB智能测试系统的软、硬件设计,系统中所研制的一体化螺钉螺母调整机构结合激光定位技术,实现了对MCCB双金属片上螺钉螺母中心的精确定位及在通电过程中对螺钉螺母进行同步一体化调整。测试系统已处于试验阶段,并取得良好的测试效果。
The tripping and calibrating principle of the MCCB was introduced.The hardware and software design of the intelligent testing system was expounded.The screw adjusting mechanism along with the laser positioning technology can precisely locate the screw on the bimetallic strip of the MCCB and complete the screw simultaneous integration when being electrified.The testing system has been in the experimental period and obtained good results.
