摘要:

海底电缆绝缘油传感器主要应用于海水中极低浓度绝缘油检测, 相比常规的水中油类传感器而言, 绝缘油检测对传感器标定流程和标准溶液制备提出了更严格的要求。本文提出新型标定方案, 设计了非接触式倒置标定结构, 通过避免探头接触溶液减少污染风险, 提升操作便利性与标定准确性; 采用了超声乳化技术制备标准溶液, 更接近海水溢油事故中自然形成的水油乳液状态; 系统探究了标定影响因素, 验证环境光干扰可忽略, 但需控制液面高度以降低气液界面信号干扰。与行业标准方法对比显示, 本方案标定结果的相对偏差为6%~10%, 在目标浓度范围内具备优异准确性。该方法为海洋生态环境监测提供了高可靠性技术支持。

Abstract:

Marine cable insulation oil sensors are primarily applied for detecting extremely low concentrations of insulating oil in seawater. Compared to conventional water-oil sensors, the detection of insulating oil imposes stricter requirements on sensor calibration processes and the preparation of standard solutions. This paper introduces a novel calibration scheme that features a non-contact inverted calibration structure designed to reduce contamination risks, thereby enhancing operational convenience and calibration accuracy. Additionally, ultrasonic emulsification technology is employed to prepare standard solutions that more closely resemble the natural water-oil emulsion state formed during seawater oil spill accidents. A systematic investigation into calibration-influencing factors reveals that environmental light interference is negligible, whereas controlling the liquid level height is critical to minimize signal interference at the gas-liquid interface. A subsequent comparative analysis with industry-standard methods demonstrates that the relative deviation of the calibration results under this scheme ranges from 6% to 10%, exhibiting excellent accuracy within the target concentration range. This method provides highly reliable technical support for marine ecological environment monitoring.
