摘要
断路器试验是电力系统一项重要而又常见的工种。传统断路器试验中使用夹子夹接断路器触头方式,存在损伤触头、夹子掉落等安全隐患,并且由于试验中相相短接采用多股铜线绕制方式,也存由于铜线毛刺而产生的尖端放电、以及遗落铜线等安全性隐患,并且效率低下。为此,研制了一种专用触头,摒弃了传统的夹子夹接及铜线绕制等试验方式,保护断路器触头,提高试验安全性和试验稳定准确性。
The breaker testing is an important and common type in power system circuit. Traditional circuit breakers used in the test circuit breaker contacts clip connection exists in the way damage the contacts, clips and other security risks falling. Because the test-phase short circuit using multi-strand copper wire mode also exists due to the copper burr generated point discharge, and left behind copper and other security risks, and inefficient. In this paper, the development of a dedicated contact, abandon the traditional clip pick and test methods, such as copper wire,protection circuit breaker contacts, improve test security and stability test accuracy.
