METHOD OF MANUFACTURING GAS-FILLED ELECTRIC SWITCH. |
摘要 |
This method of manufacturing gas-charging electric switches comprises a step of housing an electric switch in a container provided with two gas substituting ports and closing an opening of the container for the housing to render the container hermetical except at the gas substituting ports, a step of pouring a gas through one of the gas substituting ports of the container and discharging a gas in the container through the other gas substituting port to perform the gas substitution in the container and a step of tightly sealing the gas substituting ports with punches when the concentration of the charged gas in the container reaches a required level, and these steps are incorporated in other steps as sequential steps in the general atmosphere. |
