| titleOfInvention | Device and method for testing decomposition and composite characteristics of insulating gas |
| abstract | The application discloses insulating gas decomposition and composite characteristic testing device and method, and the device comprises an insulating gas tank, a buffer tank, a tube furnace, a pressure relief valve, a first gas tank, a second gas tank, a cooling tank, a vacuum pump, a mass spectrometer, a pressure gauge, a flow meter, a first three-way valve, a second three-way valve and a third three-way valve. The method comprises the following steps: extracting the air pressure value in the device to a first preset pressure value through a vacuum pump; introducing insulating gas and buffer gas into a buffer tank according to a preset proportion until the pressure in the buffer tank is at a second preset pressure value, and standing the gas in the buffer tank for a first preset time; heating the gas in the buffer tank through a tubular furnace for a second preset time, and introducing a preset amount of mixed gas into a cooling tank; and analyzing the gas in the cooling tank which is reduced to the preset temperature through a mass spectrometer. This application can accurately realize the control to gas flow, temperature and pressure, realizes the process of device gas washing, aerifys and cooling analysis. |
