摘要:: 【目的】针对传统空压机动力源漏磁检测器在新建及低流量、零输量等长输天然气管道中难以适用的问题，研制一种气电混合动力漏磁检测器，并对其技术优势进行分析与验证。【方法】根据检测器在气体管道中行进的普遍原理，基于传统空压机动力源漏磁检测器实施管道内检测时的运行状态分析，提出了气电混合动力内检测器在管道中行进的动力学模型，在漏磁检测器中额外增加电机主动驱动功能，使检测器在鼓风机和自有动力下行进，若遇阻力突变区，电机介入工作，规避了检测器卡堵憋压、发生气爆而高速行进等问题，同时保证其在管道中的通行性。【结果】气电混合动力漏磁检测器在中俄东线天然气管道工程大庆—哈尔滨（大哈）支线实施投产前内检测，在全长52 km的管道中共检测出各类特征6 930 处，并对其中1处金属损失进行开挖验证，缺陷里程、类型、地面定位信息、长度、宽度、深度、时钟位置等各项检测数据均符合相关标准要求。【结论】气电混合动力漏磁检测器采用鼓风机和自有动力作为行进动力具有明显优势，在实际工程应用中表现出较好的安全性、动力性及数据稳定性：低压低流鼓风机避免了空压机产生高压气体带来的安全隐患；速度可控使检测器可以匀速前进，保障了采集数据质量和检测精度；气动和电动双重动力作用下，检测器更快速通过穿跨越、弯头等较易卡堵位置，降低了检测器卡堵风险；若能在降低制造成本及系统复杂性、提高电池电量续航能力等方面有所改进，则应用前景广阔。

Abstract:: A hybrid pneumatic and electric power-driven leakage detector has been developed to address limitations associated with traditional polyurethane bowl-shaped detectors that rely on the air compressor for power. This detector is suitable for leakage detection in newly constructed, low-flow, or zero-flow long-distance natural gas pipelines. The hybrid power-driven leakage detector utilizes a blower and its self-powered propulsion, offering distinct advantages. The use of a low-pressure and low-flow blower eliminates the construction hazards associated with high-pressure compressed air. Controllable speed ensures the detector can move uniformly, guaranteeing the clarity and stability of collected data, reducing the likelihood of generating noise signals, and enhancing the accuracy of defect quantification. With dual pneumatic and electric power, the detector swiftly passes through challenging locations such as crossovers and bends, lowering the risk of blockages. The paper introduces the principles and structural design of the hybrid pneumatic and electric power, analyzes and compares the advantages of the hybrid detector with traditional detectors, and systematically contrasts the data analysis charts between detectors using hybrid pneumatic and electric power sources and traditional pneumatic power sources, evaluating their impact on detector accuracy. The hybrid power-driven detector's dynamic performance was validated in the field during the construction of the China-Russia Eastern Line Da-Ha branch. Original pipeline data collected by the detector were analyzed, demonstrating that the hybrid power-driven system, using a low-pressure blower for propulsion, operated safely over a distance of 52 km, mitigating compressed air hazards and enhancing safety. Comparisons with traditional air compressor-powered detectors revealed that the hybrid detector exhibited less data noise, shorter stagnation time, and overall superior safety, dynamism, and data stability in real engineering applications before pipeline commissioning.
