| Zusammenfassung: | The novel resistance-adjustable hollow fuse comprises an upper-layer insulating plate and a lower-layer insulating plate, grooves are formed in the middle parts of the upper-layer insulating plate and the lower-layer insulating plate, and at least one of the lower surface of the upper-layer insulating plate and the upper surface of the lower-layer insulating plate is provided with a resistance-adjustable electrode; the upper insulating plate and the lower insulating plate are provided with grooves; the melt is suspended in the cavity and plays a protection role when the circuit is different; the surface-mounted electrode covers at least one of the upper surface of the upper-layer insulating plate and the lower surface of the lower-layer insulating plate of the insulating plate; the through hole electrode is used for connecting the melt and the surface-mounted electrode; and the resistance adjusting electrode is used for adjusting the actual use length of the fuse and designing the electrical performance of th |
