Description

Fuse for plate-type ozone generator Technical Field The utility model relates to the field of circuit protection devices, in particular to a fuse for a plate-type ozone generator. Background The plate-type ozone generator is formed by connecting a plurality of discharge sheet units in parallel, when one unit fails, the corresponding fuse is fused, the operation is automatically stopped, and other units can continue to operate and use. The high-voltage feeder is connected with the high-voltage electrodes in the discharge chambers through the high-voltage fuses, and the high-voltage buses are communicated with the discharge chambers. In order to extinguish the arc when fusing, the high-voltage fuse is usually in a filament structure, and the longer the fuse is, the longer the fusing interval is, and the stronger the arc extinguishing capability is. However, because of the influence of some uncontrollable factors, after fusing, the fusing interval is sometimes not large enough, under the application of high-voltage electricity, the arc still continues to be drawn, heat is generated by continuous arc drawing, the ceramic shell is fused, nearby materials are carbonized, the carbonized materials have conductivity, the arc range is expanded, even fire is caused, and the high-voltage fusing protection effect of the fuse is directly guaranteed. Disclosure of utility model The utility model aims to provide a fuse for a plate-type ozone generator, which has the advantage of improving the stability and reliability of the high-voltage fusing protection effect of the fuse. The technical aim of the utility model is achieved by the following technical scheme that the fuse for the plate-type ozone generator comprises a ceramic shell and a fuse wire arranged in the shell, wherein insulating sleeves are movably sleeved at two ends of the ceramic shell, each insulating sleeve comprises a rubber sleeve joint and a wire binding opening, the diameter of each wire binding opening is smaller than that of each rubber sleeve joint, a through groove is formed in the middle of the ceramic shell, high-voltage wiring terminals are movably connected at two ends of each through groove, the fuse wire is connected between the high-voltage wiring terminals, the fuse wire comprises a connecting spring and an insulating wire, a lantern ring is arranged at one end, connected with the connecting spring, of the insulating wire, and a pull ring buckle sleeved with the lantern ring is arranged on the connecting spring. Preferably, the ceramic shell comprises a shell sleeve block and an end insert block, and the end insert block is movably sleeved with the shell sleeve block. Preferably, the outer wall of the ceramic shell at the position of the insulating wire is also sleeved with a ceramic reinforcing sleeve, and an insulating cavity is arranged between the ceramic reinforcing sleeve and the ceramic shell. Preferably, the high-voltage wiring terminal is in threaded connection with the end part of the ceramic shell.
