In some embodiments of the present invention, as shown in fig. 1-3 and 5, the aperture edge of the heat dissipation aperture 140 has a smooth transition structure.
It should be noted that by providing a smooth transition structure at the edge of the aperture of the heat dissipation hole 140, the electric field stress on the insulating housing 100 can be more uniform, thereby preventing the high-voltage electric field charges from being excessively concentrated at the edge of the aperture to cause partial discharge and breakdown, and being beneficial to improving the safety of the insulating cylinder device.
In some embodiments of the present invention, as shown in fig. 3 and 5, the driving assembly 300 includes an insulating transmission member 310, a movable contact conductive member 320, and a flexible connection member 330, the insulating transmission member 310, the movable contact conductive member 320, and the flexible connection member 330 are all disposed on the insulating housing 100, the insulating transmission member 310 is located in the second mounting cavity 120 and connected to the movable contact assembly to enable the movable contact assembly to operate, one end of the flexible connection member 330 is electrically connected to the movable contact assembly, and the other end of the flexible connection member 330 is electrically connected to the movable contact conductive member 320.
