Drop-out fuse

[0036] figure 1 It is a schematic structural diagram of a dropout fuse according to Embodiment 1 of the present invention; figure 2 It is a partial cross-sectional view of the first conductive seat of the dropout fuse according to Embodiment 1 of the present invention; image 3 It is a schematic structural diagram of the second conductive seat of the dropout fuse according to Embodiment 1 of the present invention. Such as Figure 1 to Figure 3 As shown, the dropout fuse 100 includes an insulator 101 . The insulator 101 is preferably a ceramic insulator or a synthetic insulator. The insulator 101 can be installed on the utility pole or other positions to be installed through the holed sheet 101a in the middle.

[0037] The dropout fuse 100 also includes a rainproof cap 103 formed by stamping a stainless steel plate. The structure of the rainproof cap 103 is a channel steel shape. A conductive member 106 with a slot is disposed inside the cap 103 . Wherein, the conductive me

[0067] Figure 7 It is a structural schematic diagram of the heat sink in Embodiment 3 of the present invention; in the figure, the meanings indicated by the reference signs that have appeared in the drawings used in Embodiment 2 follow the meanings in the drawings of Embodiment 2, and the newly appearing reference symbols The meanings expressed are as follows;

[0068] The difference between this embodiment and embodiment two is:

[0069] The individual heat sinks 16 are all arranged on an insulating heat conductor 23 , and the individual heat sinks 16 are divided along a circle.

[0070] The insulated heat conductor 23 can be an insulating layer attached to a metal material, so that the individual heat sinks 16 are insulated from each other without significantly reducing the thermal conductivity, so that the individual heat sinks 16 of the heat sink form a capacitor.
