Electrical connection structure, closed main busbar and gas-insulated metal-enclosed switchgear
A technology of closed switchgear and electrical connection structure, which is applied to the installation and connection of fully enclosed busbar devices and switchgears, and can solve the problem that there is no heat dissipation structure at the electrical connection structure, the flow capacity of closed busbars is restricted, and the closed busbar cannot conduct electricity normally. and other issues, to achieve the effect of improving heat dissipation efficiency, reducing frictional heat generation, and reducing installation accuracy

Embodiment approach
[0048] As another embodiment of the present invention, the spring contact fingers 5 may also be replaced by other forms of contact fingers, such as wristband contact fingers.
[0049] As another embodiment of the present invention, the insulators can also use other forms of insulators instead of pot insulators, as long as the electrical insulation between the electrical connection base and the housing can be realized, but other forms of insulators The effect is not as good as the pot insulator. The pot insulator can increase the creepage distance between the electrical connection seat and the shell, effectively preventing the risk of the insulator being broken down because the creepage distance is too short. The size of the case can be reduced.
[0050] A specific embodiment of the enclosed main busbar of the present invention has the same specific structure as that of the enclosed main busbar in the above-mentioned gas-insulated metal-enclosed switchgear, and will not be repe...
