免维护呼吸器导通检测装置的研制与应用研究

Research on Development and Application of Maintenance free Respirator Conduction Detection Device

摘要:

当前特高压换流变压器采用免维护式呼吸器替代传统呼吸器，由于无呼吸油杯，一旦发生气路堵塞无法直观判断油浸设备的呼吸状态。为此，借鉴“电子式肺功能”肺活量检测计的技术原理，设计了一种携带方便、使用便捷的导通检测装置，通过传感电路检测读取呼吸器的“呼吸状态”并就地显示读取结果，满足对换流变压器日常维护和验收工作的使用需求，同时可大幅缩短检测时间并提高检测精度。将所设计的检测装置实物样本安装在换流变压器呼吸器上，通过实验验证了其导通性检测的有效性。

Abstract:

At present, maintenance-free respirators are used to replace traditional respirators in UHV converter transformers. Due to lack of breathing oil cup, the breathing state of oil-immersed equipment can not be judged directly in case of gas circuit blockage. For this reason, the technical principle of spirometer with "electronic lung function" is used for reference to design a portable and convenient conduction detection device, which can detect and read the "breathing state" of respirator through sensing circuit and display the reading on the spot, so it can meet the use needs in daily maintenance and acceptance work of converter transformer, and at the same time, it can significantly shorten the detection time and improve the detection accuracy. Finally, a physical sample of the designed detection device is manufactured and installed on the respirators in converter transformers. The effectiveness of its conduction detection is verified by experiments.
