Embedded Pole

Abstract

The invention provides a solid-sealed pole, including a vacuum interrupter, a first conductive terminal and a second conductive terminal, the vacuum interrupter includes a central axis, a moving conductive rod and a static conductive plate; the first conductive The terminal takes the central axis as an axis of rotational symmetry. The first conductive terminal includes a circular conductive body and a circular conductive protruding ring fixed on the outer wall of the conductive body. The conductive body Sleeved on the movable conductive rod and electrically connected to the movable conductive rod, a plurality of first through holes are distributed on the conductive protruding ring; the second conductive terminal takes the central axis as the axis of rotational symmetry, And the second conductive terminal is electrically connected to the static conductive plate. The solid-sealed pole of the invention has small volume, simple structure and high safety and reliability.

Description

[0003] Chinese patent announcement number CN201332052Y discloses a solid-sealed pole, which mainly includes an insulating shell, an upper bracket for introducing current, a vacuum interrupter, a lower bracket for outputting current, and the static contact of the vacuum interrupter is electrically connected to the upper bracket. The movable conductive rod of the vacuum interrupter is electrically connected with the lower bracket through the movable sliding rod. The upper bracket and the lower bracket both extend radially outward from the embedded pole. Such an embedde...

AI Technical Summary

Problems solved by technology

The upper bracket and the lower bracket both extend radially outward from the solid-sealed pole. Such a solid-sealed pole has a large volume, complex shape, and difficult casting of insulating materials, which makes the processing process complicated.

When the circuit breaks down and the embedded pole needs to be taken out, the bus cable interface and conductor interface forming a energization circuit with the embedded pole will be exposed to the external environment, which is easily affected by the environment and brings safety hazards to the operator.
