Abstract
Disclosed is a load-shedding outdoor AC high-voltage drop fuse with a grounding switch, which is realized through the arrangement of a grounding switch on the existing load-shedding outdoor high-voltage drop fuse. The grounding switch is composed of a grounding knife (1), an upper grounding knife holder (2), a lower grounding knife holder (3) and an assistant grounding line (4), wherein, the upper grounding knife holder (2) is welded to one end of an insulation fixing framework (5); the lower grounding knife holder (3) and one end of the assistant grounding line (4) are fixed on an overall screw (6) on the bottom of an insulator; one end of the grounding knife (1) is connected on the lower grounding knife holder (3); the other end of the assistant grounding line (4) is connected on the grounding knife (1), near the lower grounding knife holder (3). When the power supply system equipment is in maintenance, the tube-shaped knife will be melted when the switch of the fuse is opened, and the equipment maintenance can be carried out when the grounding switch is shut; the utility model has the advantages of simple operation, small work amount, safety ensuring and work efficiency improvement.
Description
Technical field: the utility model relates to the power supply high voltage drop-out type fuse cutout.
Background technology: the problem that is used for the band cutting load outdoor ac high voltage drop fuse existence of power supply system at present is: when carrying out the electric power supply system equipment maintenance, after the switch that draws back fuse is the fuse tube cutter, need first electrical verification, hanging earthing conductor discharge again, just can carry out overhaul of the equipments, complex operation, workload is big, efficient is low.
Summary of the invention: the purpose of this utility model provide a kind of simple to operate, workload is little, the band cutting load outdoor ac high voltage drop fuse of the tool earthed switch that guarantees safely, increase work efficiency.It is to realize by be provided with earthed switch on the existing band cutting load outdoor ac high voltage drop fuse of being made up of insulator, upper static contact, high pressure arc-extinguish chamber, insulation fixed mount, lower support frame, following fixed contact and fuse tube cutter.Earthed switch is made up of ground connection cutter, last ground connection tool rest, following ground connection tool rest and subsidy earth connection.Last ground connection tool rest is welded on an end of insulation fixed mount, following ground connection tool rest is fixed on the overall screw of insulator bottom with an end of subsidy earth connection, one end of ground connection cutter is connected down on the ground connection tool rest, and the other end of subsidy earth connection is connected nearly ground connection tool rest place down on the ground connection cutter.When carrying out electric power supply system equipment when maintenance, after the switch that draws back fuse was the fuse tube cutter, the earthed switch that only need close can carry out overhaul of the equipments, it have simple to operate, workload is little, the advantage that guarantees safely, increase work efficiency.
Description of drawings: be the utility model example structure schematic diagram.
Embodiment: as shown in the figure, it is to realize by be provided with earthed switch on the existing band cutting load outdoor ac high voltage drop fuse of being made up of insulator, upper static contact, high pressure arc-extinguish chamber, insulation fixed mount, lower support frame, following fixed contact and fuse tube cutter.Earthed switch is made up of ground connection cutter 1, last ground connection tool rest 2, following ground connection tool rest 3 and subsidy earth connection 4.Last ground connection tool rest 2 is welded on an end of insulation fixed mount 5, following ground connection tool rest 3 is fixed on the overall screw 6 of insulator bottom with an end of subsidy earth connection 4, one end of ground connection cutter 1 is connected down on the ground connection tool rest 2, and the other end of subsidy earth connection 4 is connected nearly ground connection tool rest 2 places down on the ground connection cutter 1.
