一种用于GIS设备的闭式循环气体在线取样回收装置
摘要：
本发明提出一种用于GIS设备的闭式循环气体在线取样回收装置，所述GIS设备的外壳具有进气口和出气口，包括：第一开关阀，所述第一开关阀的输入端与所述出气口相连；减压阀，所述减压阀的输入端与所述第一开关阀的输出端相连；具有进口和出口的待测气室，所述进口与所述减压阀的输出端相连；第二开关阀，所述第二开关阀的输入端与所述出口相连；抽气泵，所述抽气泵的输入端与所述第二开关阀的输出端相连；储气罐，所述储气罐的输入端与所述抽气泵的输出端相连且所述储气罐的输出端与所述进气口相连。根据本发明实施例的一种用于GIS设备的闭式循环气体在线取样回收装置，结构简单，可以完成GIS设备内的SF6进行检测，不会发生泄漏，安全可靠。
摘要（英）：

The invention provides a closed circular gas online sampling recycling device for a GIS device. The outer shell of the GIS device is provided with an air inlet and an air outlet; the closed circular gas online sampling recycling device comprises a first switch valve, a reducing valve, a second switch valve, a to-be-tested air chamber, a gas pump, and a gas storage tank; an input end of the first switch valve is connected with the air outlet, and the input end of the reducing valve is connected with the output end of the first switch valve; the to-be-tested air chamber is provided with an inletand an outlet, and the inlet is connected with the output end of the reducing valve; the input end of the second switch valve is connected with the outlet; the input end of the gas pump is connectedwith the output end of the second switch valve; the input end of the gas storage tank is connected with the output end of the gas pump and the output end thereof is connected with the gas inlet. The closed circular gas online sampling recycling device for the GIS device is simple in structure, and can detect SF6 in the GIS device; the device is free from leakage, and is safe and reliable.
