实用新型
CN201751858U 一种试验回路 失效 - 放弃

一种试验回路
摘要：
本实用新型提供一种试验回路，所述试验回路包括：第一隔离开关设备、第二隔离开关设备、第一隔离管套、第二隔离管套；第一隔离开关设备的一端通过管道与第二隔离开关设备的一端连接，第一隔离开关设备的另一端通过管道与第一隔离管套一端连接，第二隔离开关设备的另一端通过管道与第二隔离管套的一端连接，还包括：分支母线，分支母线的一端连接在第一隔离开关设备和第一隔离管套之间的管道上，另一端悬空，通过改变分支母线的长度来模拟GIS变电站中不同的GIS接线方式，以模拟GIS变电站中不同的GIS接线方式下隔离开关断口和GIS管道上出现的VFTO波形。
摘要（英）：

The utility model provides a test loop comprising a first isolating switch device, a second isolating switch device, a first isolating pipe sleeve, a second isolating pipe sleeve, as well as a branch bus, wherein one end of the first isolating switch device is connected with one end of the second isolating switch device through a pipeline, while the other end of the first isolating switch device is connected with one end of the first isolating pipe sleeve through a pipeline; the other end of the second isolating switch device is connected with one end of the second isolating pipe sleeve through a pipeline; one end of the branch bus is connected on the pipeline between the first isolating switch device and the first isolating pipe sleeve, while the other end is suspended; and different GIS (gas insulated substation) connection modes in a GIS are imitated by changing the length of the branch bus, so that the VFTO (very fast transient overvoltage) wave forms occurring at the disconnection port of an isolating switch and a GIS pipeline under different GIS connection modes in the GIS are imitated.
