The current market The existing isolating switch in the world has rough technology and cannot realize automatic switching. It is generally replaced by SF6 load switch, but although the SF6 load switch has a disconnection point, it is not visible.

SF6 load switch uses sulfur hexafluoride as the insulating gas. Although the insulation performance is excellent, the greenhouse effect will be aggravated due to the dissociation and escape of sulfur hexafluoride, which does not meet the environmental protection requirements. The structure of a common high-voltage isolating switch is as follows: insulators are respectively arranged under the two ends of the bracket, and conductive plates are respectively arranged under the two insulators. Snap-in connection; this traditional high-voltage isolating switch is easy to operate, but this switch does not have intelligence, and requires the staff to use insulating rods to complete the opening and closing of the switch, and the isolating blade of this kind of switch is used for a period of time. The connection is not tight enough, resulting in circuit failure, and there is no lightning protection device, which poses a great safety hazard in thunderstorm weather.
