Embodiment 1
[0028] figure 1 It is a schematic structural diagram of the drop arrester 100 according to Embodiment 1 of the present invention; figure 2 It is a partial cross-sectional view of the first conductive seat of the drop-out arrester according to Embodiment 1 of the present invention; image 3 It is a schematic structural diagram of the second conductive seat of the dropout arrester according to Embodiment 1 of the present invention. Such as figure 1 and image 3 As shown, the drop arrester 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.
[0029] The drop arrester 100 also includes a rainproof cap 103 . The left end of the rainproof cap 103 is connected to the upper end of the insulator 101 , and a conductive member 106 with a card slot is arranged inside the rainproof cap 103 . T...
Embodiment 2
[0036] Figure 4 It is the detection system and the dust cleaning system of the drop arrester of the second embodiment of the present invention; Figure 5 It is the circuit diagram of the detection system of the drop arrester of the second embodiment of the present invention; Figure 6 is a partial view of the self-adaptive air outlet in Embodiment 2; Figure 7 It is a partial view of the heat sink of the component in the second embodiment; among the figures, the meanings indicated by each reference mark are as follows; 1, the housing; 2, the PCB circuit board; 11, cleaning the air intake device; 12, the filter device; 13, Cleaning pipeline; 14. Self-adaptive air outlet; 15. Bimetal sheet; 16. Single heat sink; 17. Mirror surface; 18. Photosensitive switch; 19. Circuit components; 20. Air exhaust port; ; 24. Laser generator. The second embodiment is to increase the detection system and the dust cleaning system on the basis of the first embodiment.

Embodiment 3
[0059] Figure 8 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;
[0060] The difference between this embodiment and embodiment two is:
[0061] 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.
[0062] 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.
