摘要

摘要: 介绍了真空断路器真空度检测方法——观察法、工频耐压法、脉冲磁控放电法、屏蔽罩电位法等离线式检测方法和耦合电容法、局部放电法、旋转电场探头法、X射线法、内置传感器法等在线式检测方法的研究现状，分析了各方法的检测原理、特点和应用情况。指出真空度离线式检测方法中脉冲磁控放电法和工频耐压法因为成本低、检测简单和重复性好，成为目前应用最广泛的真空度检测方法，但定期停机检查真空度成为制约该类方法发展的最主要因素；真空度在线式检测方法可实时检测真空度，及时发现真空度的劣化，但存在精度较低、成本高、抗干扰能力和稳定性较差等问题，因此未得到广泛应用。提出提高真空度在线式检测方法精度和融合多种真空度检测方法是真空断路器真空度检测方法的发展趋势。

Abstract: Research status of vacuum degree detection methods for vacuum circuit breaker was introduced including off-line detection methods such as observation method, power frequency withstand voltage method, pulsed magnetron discharge method and shield potential method, and on-line detection methods such as coupling capacitance method, partial discharge method, rotary electric field probe method, X ray method and built-in sensor method. Though analyzing detection principle, characteristics and application of each method, it indicated that pulsed magnetron discharge method and power frequency withstand voltage method in off-line detection methods were the most widely applied because of low cost, simple detection and good repeatability, but regular stopping to check vacuum degree became the most important factor to restrict development of the off-line detection methods, and on-line detection methods could detect vacuum degree in real time and find deterioration of vacuum degree, but the methods were not widely applied because of low accuracy, high cost and poor anti-interference and stability. Development trends of vacuum degree detection method for vacuum circuit breaker were proposed, which were improving accuracy of on-line vacuum degree detection method and integrating multiple vacuum degree detection methods.
