一种断路器行程测量方法及系统
摘要：
本发明涉及一种断路器行程测量方法及系统，属于电力系统一次设备智能化技术领域。本发明通过检测断路器动作前辅助触点的位置，根据检测结果判断断路器所处状态；利用增量型编码器测量断路器动触点的旋转角度，并根据两路正交编码输出趋势的变化，确定断路器分闸或合闸的动作方向；根据当前断路器初始位置及操作预期，将判定的方向与断路器分、合闸操作的动作过程相对应本发明不受安装方向的影响，完成断路器行程变化的测量，为断路器行程、速度和动作时间等参量计算提供数据支持。
摘要（英）：

The invention relates to a breaker travel measuring method and system and belongs to the technical field of power system primary equipment intelligence. The method includes: the position of an auxiliary contact of a breaker is detected before the action of the breaker, and the state of the breaker is judged according to the detecting result; an increment encoder is used to measure the rotation angle of the breaker movable contact, and tripping and closing action directions of the breaker are determined according to the output tendency of quadrature encoding; corresponding the tripping and closing actions to the determined directions according to the current initial position of the breaker and operation expectation. By the method, breaker travel variation can be measured without being influenced by mounting directions, and data support can be provided for calculation of parameters such as travel, speed and action time.
