<p>The present invention relates to a method for manufacturing a vacuum interrupter for a vacuum circuit breaker and, more particularly, to a method for manufacturing a vacuum interrupter for a vacuum circuit breaker capable of improving insulation performance. The method for manufacturing the vacuum interrupter for the vacuum circuit breaker according to one embodiment of the present invention includes the steps of: inputting the vacuum interrupter to a vacuum furnace; brazing the vacuum interrupter by heating the inside of the vacuum furnace by a heater when a vacuum state is maintained in the vacuum furnace; cooling the vacuum interrupter by injecting argon and hydrogen gas mixture into the vacuum furnace; and taking out the vacuum interrupter from the inside of the vacuum furnace at room temperature. The present invention prevents metal oxide from being contaminated or deposited in an insulation container of the vacuum interrupter by reducing the metal oxide formed in the vacuum furnace by the hydrogen gas.</p> |
