Gas insulated switchgear isolation switch contact state test and measurement system
2015
The invention discloses a gas insulated switchgear (GIS) isolation switch contact state test and measurement system, comprising a GIS housing, a vibration accelerometer, an oscilloscope, and a heat flow device. The vibration accelerometer is arranged at the top of the GIS housing; the oscilloscope is arranged above the upper portion of the vibration accelerometer; the heat flow device sleeves the bottom of the GIS housing; the lower portion of the heat flow device is provided with a heat flow device operating console; the GIS housing is internally provided with a test cavity; a guide rod is arranged between the GIS housing and the test cavity, and is provided with an isolation switch; the bottom of the GIS housing and the bottom of the test cavity are in connection through a disc insulator. The GIS isolation switch contact state test and measurement system realizes the vibration signal characteristic analysis of the isolation switch in a GIS in different contact states.
