Abstract

The invention relates to a gas taking connector and an online gas taking method. The gas taking connector comprises a fixed nut, a valve core with a gas taking ejector pin, a propelling part and a quick connector with an automatic sealing structure, wherein the gas taking ejector pin is fixed in the valve core, a through air duct is formed along the axial direction of the valve core, a pin head part stretches out of the front end of the valve core, and the front part and the rear part of the valve core are respectively provided with a baffle mechanism; the propelling part is arranged outside the valve core in a sleeving manner and snapped between the baffle mechanisms on the front part and the rear part of the valve core, the periphery of the propelling part is provided with outer threads which are matched with the inner threads of the fixed nut, and the propelling part is also provided with a propelling control part so as to drive the valve core to move in the fixed nut; one end of the quick connector can be connected with the tail end of the valve core in a sealing manner. By adopting the gas taking connector and the online gas taking method, the gas leakage in the gas taking process can be maximally eliminated, and the potential danger caused by the fault operation of people in the detection process can be prevented by virtue of the normalized operation method.

Description

technical field [0001] The invention relates to a gas-taking joint, in particular to a gas-taking joint and an online gas-taking method for online gas-taking detection of sulfur hexafluoride electrical equipment. Background technique [0002] With the rapid development of the power industry in recent years, sulfur hexafluoride (SF 6 ) high-voltage power transmission and transformation equipment with gas as the insulating medium has been widely used in the power industry due to its superior electrical performance, such as fully enclosed combined electrical appliances (GIS), circuit breakers, transformers, transformers, cables, etc. With the popularization of the application of such high-voltage electrical equipment, internal equipment failures caused by various factors (such as product design, raw materials, manufacturing and installation processes, and product aging) have a serious impact on the safe operation of the power grid and reliable power supply. have happened. The...
