作業スペースを減少させることになる。The load switch with a single-phase fuse is divided into a plurality of phases,
In a load switch with a fuse in which the insulating barriers 1 are arranged in parallel and the phases are arranged between the phases, if the size is reduced in the inter-phase direction, the insulating barrier 1 approaches the fuses 3 so that the work space for removing the fuses is reduced.

In addition, by using an integrally molded product in which the concave and convex portion 2 for securing a working space by casting is provided on the side surface of the fuse 3, air can easily flow through the space between the fuse 3 and the insulating barrier 1. . Therefore, during normal operation, the cooling effect of the fuse can be improved, and the temperature inside the load switch with the fuse can be easily managed.

さらに相間距離を短くすることが出来る。FIG. 5 shows another embodiment having the same purpose as that of the above embodiment, but having a different shape of the insulating barrier 1. In the embodiment shown in the figure, the uneven portion 2 of the insulating barrier 1 is formed into a curved surface. As a result, the concentration of the electric field and the stress can be reduced, so that the inter-phase distance can be further reduced as compared with the embodiment shown in FIG.

In this embodiment, in addition to the two locations of the power supply side fuse clip 4 and the load side fuse clip 14, the uneven portion 2 is further formed at one location near the center of the mounting position of the fuse 3. This facilitates the screwing operation and facilitates the removal of the fuse 3.

外すことが出来る。FIG. 7 shows an embodiment in which the positions of the concave and convex portions in the insulating barrier 1 are different. In this embodiment, the unevenness portion 2 for securing a work space is deviated from the center of the mounting position of the fuse 3 to the lower side in FIG.
The position where the hand is held is limited, so the removal force is biased to one side. Therefore, when removing the fuse 3, the fuse 3 can be easily removed from the load-side fuse clip 14 using the power supply side fuse clip 4 as a fulcrum and utilizing the leverage principle.

る。The embodiment in which the present invention is applied to a load switch with a fuse has been described above. However, the present invention is also applicable to a case where an insulating barrier is provided between phases only by a fuse and the operability is reduced by the insulating barrier. Can be applied to things.
【００３０】[0030]
【発明の効果】以上、本発明によれば、比較的容易にヒ
ューズの取外しが行なえるので作業効率が良く、作業を
確実に行なうことができる。As described above, according to the present invention, the fuse can be removed relatively easily, so that the work efficiency is good and the work can be performed reliably.

冷却効率の向上が図れる。従って、ヒューズ付負荷開閉

障を防止することが出来る。Since a space can be secured around the fuse by the concave and convex portions formed on the insulating barrier, the cooling efficiency of the fuse can be improved. Therefore, the temperature inside the load switch with a fuse can be easily managed, and a failure due to a rise in temperature can be prevented.

従って、ヒューズ付負荷開閉器の軽量化が図れる。By providing the insulating barrier with irregularities,
Since the pressure due to the arc generated by a ground fault or the like passes through the uneven portion formed on the insulation barrier and escapes outside the load switch with the fuse, the pressure received by the insulation barrier itself is reduced,
The thickness of the insulating barrier can be made smaller than before.
Therefore, the load switch with fuse can be reduced in weight.
