Title (EN) METHOD OF MANUFACTURING GAS-FILLED ELECTRIC SWITCH
(FR) METHODE DE FABRICATION D"UN COMMUTATEUR ELECTRIQUE REMPLI DE GAZ
Abstract: front page image
(EN)A method of manufacturing a gas-filled electric switch comprising the steps of; disposing an electric switch unit (2) in a container (1) having two vent holes, closing an opening of the container, through which the electric switch unit is disposed in the container, to thereby airtightly seal the container except the two vent holes, charging a required gas into the container through any one of the two vent holes while exhausting through another vent hole to thereby substitute is exhausted from the other the required gas for the gas in the container, and sealing the holes by means of punching means (10) when the concentration of the required gas in the container has reached a predetermined level. These steps may be associated in continuation with other manufacturing steps under a normal atmosphere.
(FR)Une methode de fabrication d"un commutateur electrique rempli de gaz consiste a disposer un commutateur electrique (2) dans une enceinte (1) ayant deux orifices d"event, a fermer une ouverture de l"enceinte, a travers laquelle le commutateur electrique est dispose dans l"enceinte, de maniere a fermer hermetiquement a l"air l"enceinte a l"exception des deux orifices d"event, a charger un gaz choisi dans l"enceinte au travers d"un des deux orifices d"event tout en refoulant par l"autre orifice d"event de maniere a substituer le gaz dans l"enceinte par le gaz requis, et a obturer les orifices a l"aide de moyen de poinconnement (10) lorsque la concentration du gaz requis dans l"enceinte a atteint un niveau predetermine. Ces etapes peuvent etre associees a la suite d"autres etapes de fabrication dans une atmosphere normale.
