に示されている。Conventional movable mold lids include, for example, those shown in FIGS. 5 and 6 (a) and (b). The movable mold lid 12 has a movable electrode 1 that can be electrically connected to the contacts in the fixed molds 8A and 8B inside the opening 12a that fits into the L-shaped fixed molds 8A and 8B. With the cable fixed to the fixed molds 8a and 8B,
It is composed of a buried conductor 13 for electrically connecting the mold busbar 9 and the epoxy bush 9, and an epoxy insulator 2 forming the opening 12a and insulating the buried conductor 13. Epoxy insulator 2
The surface is covered with a conductive material to form a shielding layer, and the charged part is concealed to improve safety.
As shown in FIGS. 6 (a) and 6 (b), the movable mold lid 12 is made up of a pair of a fixed mold 8A connected to the cable terminal connecting portion 10 and a fixed mold 8B connected to the mold busbar 9. The resin mold type air interrupter is inserted and opened by being attached to and detached from the fixed mold. Such a disconnector is disclosed, for example, in Japanese Utility Model Publication No. 57-499.

なかった。However, in the disconnector using the conventional movable mold lid,
Since the charging section is completely concealed, there is a disadvantage that a power outage cannot be avoided when the emergency power supply is taken out. For example, to take out the emergency power supply, FIG. 6 (a)
As shown in the figure, the movable mold lid 12 is opened to be pulled out from the conductor of the fixed mold 8A, or the movable mold lid 12 is similarly opened to remove the cable terminal connection portion 10 and the removed portion of the fixed mold 8A is removed. Although it is possible to draw out from the conductor or some other method, a power failure due to opening the movable mold lid 12 is inevitable. Further, even if such an operation for taking out the emergency power supply is performed, the operation is troublesome, and thus it is not practical. For this reason, power supply to customers in the construction section during cable construction, etc. (bypass construction)
At times, the method of extracting emergency power from overhead wires is common, and emergency power is not extracted from disconnectors.
