Example Embodiment
[0017] The embodiment of the high-voltage DC grounding switch of the present invention: such as Figure 1-6 As shown, it mainly includes a base 8, a moving contact 12, a static contact 2, a grounding knife 7, and an operating mechanism 4. The upper end of the static contact 2 is fixedly provided with a tube bus clamp 6, and the static contact can be fixed through the tube bus clamp 6. The contact 2 is directly positioned and hung on the tube bus 1. A shielding system is also provided on the tube bus clamp 6. The shielding system consists of an upper equalizing ring 5 and a lower equalizing ring 3, wherein the upper equalizing ring 5 is fixed on the tube The top of the bus clamp 6, the lower equalizing ring 3 is fixed on the bottom of the tube bus clamp 6. The static contact 2, the tube bus clamp 6, the upper equalizing ring 5 and the lower equalizing ring 3 form a static contact assembly; static contact 2 includes a cylindrical guide cover 21, the lower end of which is flared do...
