る。The movable shaft 4 of 3 is connected to the main circuit conductor 6 via a collector contact 5. The fixed shaft 7 of the vacuum valve 3 is connected to the main circuit conductor 8
The connection is fixed. With this configuration, when the contacts of the vacuum pulp 3 are closed, the current of the main circuit passes through the main circuit conductor 6, the current collector contact 5, the movable shaft 4 and the fixed shaft 7 of the vacuum pulp 3, and then passes through the main circuit conductor 8. energized to form a phase II current path. Further, the movable shaft 4 of the vacuum pulp 3 is connected to an insulated operating rod 11 via a lick 9 and a spring lO.

などの問題がある。By the way, the vacuum cutoff f? of the configuration shown in Figure 1? The upper limit value of the temperature rise of the main circuit current is determined by the standard for the current carrying current capacity of s. For example, the upper limit value of the temperature rise in the case of silver-iron contact is 65°C, which is the maximum value of the current flow. The value must satisfy this temperature rise value. Furthermore, since the interior of the vacuum valve 3, which is the cutoff part of the vacuum breaker and is also the current carrying part, is in a high vacuum, it is impossible to directly radiate heat to the outside from the contact part. Therefore, the heat generated at the contact point (Joule heat due to energization) is transferred to the movable shaft 4 of the vacuum valve 3 and the fixed
! The heat is drawn out by heat conduction at 1117 and then radiated. Therefore, in order to increase the current carrying capacity of the Makabe breaker, it is necessary to increase the cross-sectional area of the movable shaft 4 and the fixed shaft 7 of the vacuum valve 3. It will be necessary to replace the metal bellows with large cedar. This causes problems such as an increase in the manufacturing cost of the vacuum valve itself and an increase in the size of the vacuum valve.

なく、主回路の通電容量を増すことのできる真空しゃ断
器を提供することを目的とする。An object of the present invention is to provide a vacuum breaker that can increase the current carrying capacity of the main circuit without increasing the size of the vacuum valve of the vacuum breaker.
