Described ground connection auxiliary rod 9 is for hanging earth lead.
Described upper connecting terminal 5 is connected with power circuit by insulated conductor with lower connecting terminal 8.
Described fusion tube 12 is connected on lower duckbilled 7 by rotating shaft, by pulling link 11 to be closed on static contact 6 by moving contact 10.
Operation principle:
During use, staff steps on bar at cross-arm 1, rope is utilized to be carried to cross-arm by Novel outdoor fuse switch, V-type anchor ear 2 is enclosed within cross-arm 1, and tighten the nut of V-type anchor ear 2, whole disconnecting link is fixed on cross-arm 1 firmly by V-type anchor ear 2, is connected with top power circuit by upper connecting terminal 4.It is connected with bottom power circuit by lower connecting terminal 8.After installation, staff's lower beam.
If Guan Bi power circuit, staff uses insulating bar to hook on link 11, is closed with static contact 6 by moving contact 10 by operation fusion tube 12.If disconnection power circuit, staff uses insulating bar to hook on link 11, is separated with static contact 6 by moving contact 10 by operation fusion tube 12.
If power circuit needs to proceed to inspecting state, then use insulating bar to hook on link 11, by operation fusion tube 12, moving contact 10 is separated with static contact 6.After forming effective fracture, earth lead is suspended on ground connection auxiliary rod 9, completes power circuit reliable ground, it is ensured that the safety of operating personnel on power circuit.
After Novel outdoor fuse switch installation, it is ensured that power circuit is properly functioning.When occurring short circuit or the fault such as overvoltage, overcurrent in power circuit, the fuse in fusion tube 12 will fuse, and cut off power circuit.Its principle is that the lower end spring structure of fusion tube 12 relies on fuse to fasten, and moving contact 10 is pushed the projection of upper duckbilled 4 by fusion tube 12, with static contact 6 tight closure.When short circuit current is by fuse failure, producing electric arc, the vulcanized fiber tube of fusion tube 12 liner produces substantial amounts of gas because being shut fusion tube 12 upper end under arcing, and gas sprays to lower end, blows out electric arc.Due to fuse failure, the spring structure of fusion tube 12 lower end loses the fastening force of fuse and relaxes, and under the effect of cartridge fuse self gravitation and static contact 6 spring leaf, fusion tube 12 falls rapidly, makes circuit disconnect, excision faulty section circuit or faulty equipment.
