核电厂控制棒棒位测量系统及测量方法
摘要：
本发明公开了一种核电厂控制棒棒位测量系统，包括棒位探测器、数据采集柜和棒位逻辑柜；所述棒位探测器包括探测器套管、自感线圈和电连接器；自感线圈呈离散式布置在探测器套管上，各离散式自感线圈与电连接器连接，电连接器通过一组探测器电缆与数据采集柜连接，将探测电压信号输出给数据采集柜；数据采集柜和棒位逻辑柜根据探测电压信号确定控制棒棒位。本发明还公开了一种核电厂控制棒棒位测量方法。本发明控制棒棒位测量系统和测量方法采用基于电感自感式位移测量传感器的控制棒棒位测量技术，减少了探测器线圈的总数量，有效改善了探测器线圈的散热，并解决了探测器线圈连接焊点破坏导致整个棒位探测器棒位探测功能丧失的问题。
摘要（英）：

The invention discloses a nuclear power plant control rod position measuring system, comprising a rod position detector, a data collection cabinet and a rod position logic cabinet; the rod position detector comprises a detector sleeve, self-induction coils and an electric connector; the self-induction coils are disposed on the detector sleeve in a disperse manner and are connected with the electric connector, and the electric connector is connected with the data collection cabinet through a group of detector cables to transmit detection voltage signals to the data collection cabinet; the data collection cabinet and the rod position logic cabinet determine the rod position of the control rod according to the detection voltage signals. The invention also discloses a nuclear power plant control rod position measuring method. According to the control rod position measuring system and method, control rod position measuring technology based on inductance self-induction displacement measuring sensor is used, the total quantity of detector coils is creased, heat radiation of the detection coils is effectively improved, and the problem that rod position detection function of the whole rod position detector is lost due to the damage of detector coil connection welding spots is solved.
