ときの引掛け部である。 The fixed contact portion 16 of the switch 11 is molded integrally with the arc-extinguishing cylinder 17 from a molded insulator so as to cover the fixed electrode 12, and the fuse chamber 30 molded integrally with the fixed contact portion 16 from this molded insulator has a cavity for housing an insulating cylinder 19 that is sufficiently longer than the length of the fuse 20, and an outlet port that allows the insulating cylinder 19 to be attached and detached. A plug 26 with a transparent window 25 is fitted into this outlet portion, and the insulating cylinder 19 housing the power fuse 20 is inserted into the fuse chamber 30, and the plug 26 is inserted.
By covering the insulating cylinder 19, the power fuse 20 is arranged so that it can be electrically connected. The tip 27 of the movable contact 15 is located on the same side as the plug 26, in other words, the fixed contact 16 of the switch 11 is integrally molded with a molded insulator at the base end of the fuse chamber 30 in which the insulating cylinder 19 is housed, and the tip 27 of the movable contact 15 is located so as to cover the plug 26 when the switch 11 is closed, so that the plug 26 cannot be removed when the switch 11 is closed. In Fig. 2, 28 is the outer periphery of the molded insulator and the ground layer of the movable contact 15, which serves to prevent electric shock, 29 is the transformer tank, 31 is an installation flange, and 32 is a hook when the insulating cylinder 19 is pulled out.

業が可能となる。 When replacing the power fuse 20, first replace the switch 1.
When the movable contact portion 15 is moved to cut off the plug 2, the tip portion 27 becomes unlocked and separates from the plug 26, allowing the plug 26 to be removed.
6, the insulating cylinder 19 can be pulled out from the fuse chamber 30. In this case, by taking the insulating cylinder 19 out of the fuse chamber 30, the terminal 24 and the power fuse 20 are completely electrically disconnected.
Even if electric charges should remain in the terminal 24, replacement work can be carried out safely.

Further, since the fuse chamber and the switch are molded with a molded insulator, they are not affected by the outside air as in the conventional case, which helps reduce the above-mentioned risks. In particular, this invention can be applied to equipment such as transformers that have bushings, and the switch and fuse are integrated with molded insulators and are formed long, eliminating the need for bushings. Wiring of connection lines can be omitted and short circuits between lines can be prevented.
