ることも容器を高価にする。 The vacuum shield disconnector is constructed as shown in FIG. In FIG. 1, the vacuum container is constructed by fixing an insulating end plate 2 made of ceramic to the opening of a cup-shaped metal container 1 (usually made of copper) by brazing or other means, and then placing the metal container 1 face down. Formed in a state. An electrode holder 4 having a fixed electrode 3 provided inside is passed through and fixed to the bottom (upper part in the figure) of the metal container 1, and a fixed lead rod 5 is fixed to the outside of the holder 4. . 6 is a movable electrode, and this electrode 6 is provided opposite to the fixed electrode 3 and is fixed to the movable lead rod 7. This movable lead rod 7 passes through the insulating end plate 2 via a bellows 8 and extends to the outside. Although the vacuum shield and disconnector are constructed in this way, the metal container 1 is usually made of copper in order to facilitate brazing with the end plate 2. However, the copper container 1 is heated to high temperatures during brazing, vacuum degassing, and the like. As a result, the copper becomes dull and becomes a soft material in terms of strength. For this reason, if the inside of the container 1 is made to be in a high vacuum, the container 1 must be made to withstand atmospheric pressure, or be made strong enough to not deform when handled during container manufacturing or after becoming a product. The thickness of the plate will have to be increased. As a result, the weight of the container increases and more materials are required, making the container more expensive. In addition, the surface of copper containers tends to change color over time (it turns black when oxidized or sulfurized), which reduces its commercial value. For this reason, copper containers are commonly coated or plated to prevent discoloration. Using such means also makes the container expensive.

供することを目的とする。 This invention was made in view of the above circumstances, and by manufacturing a vacuum container from a clad metal of copper plate and stainless steel plate or copper plate and steel plate, it is possible to reduce the weight of the container, save on materials, and manufacture it at low cost. The purpose of the present invention is to provide a vacuum breaker and disconnector.

１０ａの部分で封着される。 In Figure 2, a metal container 1 has a copper plate 1 inside.
0a on the outer surface of the copper plate 10a.
Metal plate 10b that is stronger and is a high melting point metal
It is formed of a clad metal 10 (for example, stainless steel or steel plate). The sealing between the metal container 1 formed from the clad metal 10 and the insulating end plate 2 is performed using the copper plate 1 of the clad metal 10.
This is done by brazing at part 0a. The fixed electrode 3 is directly attached to the fixed lead rod 5 without providing an electrode holder.
This fixed lead rod 5 is fixed to the metal container 1.
It is fixed by penetrating the bottom of the. This fixed portion is sealed at the copper plate 10a.

が確実に絶縁端板２に密着するようにした。 The thickness of the copper plate 10a of the clad metal 10 is the minimum thickness necessary for sealing with the insulating end plate.
The strength of the copper plate 10a may be supplemented by the metal plate 10b. Further, FIG. 3 shows an embodiment in which the clad metal 10 is constructed by providing an extremely thin copper plate 10a inside the metal plate 10b.
The end of the copper plate 10a is formed into a flange part 11.
is ensured to be in close contact with the insulating end plate 2.

る。 When the container 1 is constructed using the clad metal 10 as described above, it is possible to manufacture the container with a thinner plate than that of a container made only of copper plates, thereby reducing the amount of expensive copper used. It is possible to reduce the weight of the container. Therefore, it is possible to reduce the weight and size of the vacuum shield and disconnector. Furthermore, if stainless steel is used for the metal plate 10b, rust prevention treatment and surface treatment of the container are not required, and discoloration and scratches can be prevented during manufacturing or storage of the product, and there is no reduction in commercial value. In particular, the embodiment shown in FIG. 3 has the advantage that the amount of copper used can be extremely reduced.
