Outdoors decline 35kV of type high voltage fuse and the following outdoor type high voltage fuse basically are to decline type high voltage fuse. Basically use at protecting transmission network and distribution transformer.
This kind of fuse is in charge of composition by the fusing of fixed bracket and activity. Fusing is in charge of (fuse-element is in charge of) coil by colophony layer chipboard is made, intermediate line with asbestine. Bake a two end a paragraph of join uses each crimp braid cupreous skeining thread, it crosses fusing canal, secure fluctuation with screw of two end move touch a head to go up, go up movably touch a head by frit silk taut and fixed, be gotten on static those who touch a head to go up " duck mouth " medium protruding maintains card to live, fusing
Implement be in " access " the position, when frit silk frit is new. Electric arc arises inside frit canal. Bake tubal wall produces a large number of gas below electric arc action, aeriform Gaolian is outward and ejective, generation goes strongly free action, pass in electric current when waiting, extinguish electric arc. In the meantime, after frit silk fusing, on fusing canal on the pine that touch a head is taken off, what be in charge of as a result of frit is self-prossessed and from go up static touch a head " duck mouth " in surge, rapid Fu falls. The frit canal of this fuse is after frit silk fusing. Decline automatically, make fusing designation on one hand, cause on the other hand apparent before disconnect distance, have the effect of F switch-disconnector. Can use high-pressured insulation pull rod as a result of it again (operation lever, pull close to carry the distribution sky under circuit or 560kVA to carry transformer for nothing (when pulling switch, operate lever top to move with high-pressured insulation only " duck mouth " , fusing canal namely can proper motion Fu falls · is cut off carry for nothing
Circuit; When stage brake, want to use insulation lever one by one to turn fusing valve the table only. Put through namely carry circuit) for nothing, cropland this, in distribution system Fu falls type fuse application is very wide.
Decline type fuse still can make heavy stage switch, it has two fusing canal. Normal when, only ~ covers fusing canal to put through after its fusing declines, when asking it is certain to lie between, be the same as (O of ~ agreement O3. 5s) , another borrows the 35kV transformer that weigh stage brake orgnaization automatically and measures to Xiaorong on automatic coincide to also be popularized use Fu to fall type fuse protection, namely Rw535, use at replacing old product _Rwl35 high pressure to break implement. It and 10kV decline type fuse kind with, it is frit only the canal is some longer. Somes over all dimension is big (two static touch a head to use two pedestal insulator to secure) .
