摘　　要：针对六氟化硫现场检测时可能存在自封闭逆止阀不能复位,导致设备快速泄压的风险,研制了一种在测试时能有效防止设备快速泄压的检测接头。该检测接头与常规检测接头最大区别在于顶针与连接螺帽非固定结构设计,主要包括连接螺帽、顶针管、连接套、压缩弹簧、压簧螺帽等部件。防泄压检测接头的使用可避免测试时设备泄压而导致的人身、设备、电网安全风险,并可避免大量六氟化硫温室气体直接向大气排放。Aimed at the problem that the self-close check valve can not reset when SF6 on-site detection, it will lead to risk of equipment＇ s rapid decompression. We designed a detection joint which can effectively prevent equipment rapid relief. The best difference between the new detecting joint and the normal is the unfixed structure of the thimble and coupling nut, including the coupling nut, thimble tube, connecting sleeve, compression spring, spring nut, etc. The use of the new detecting joint can avoid the risk of personal security, equipment security, power grid security and environmental pollution, caused by SF6 gas leakage in SF6 field detection.
