AI Technical Summary

⚠Technical Problem

Existing load switches are prone to generating electric arcs when the stationary and moving contacts are broken, leading to contact erosion, electromagnetic radiation, and noise interference, which affects the safe and stable operation of the power system.

⚗Method used

An arc-extinguishing device is used, which utilizes environmentally friendly gas inside the vacuum bubble to introduce a vacuum environment when the moving contact and the stationary contact separate, thereby suppressing the generation of electric arc and forming a new current path through the conductive components and the vacuum bubble.

🎯Benefits of technology

It effectively suppresses the generation of electric arcs, extends contact life, reduces equipment maintenance costs, reduces electromagnetic radiation and noise interference, and ensures the safe and stable operation of the power system.

Abstract

The application discloses an environmental protection gas load switch and belongs to the electrical equipment field, which is used to solve the problem of how to inhibit or eliminate the arc generated when the static contact and the moving contact of the load switch are disconnected. The environmental protection gas load switch comprises a shell, a moving contact, an operating mechanism, a first static contact and an arc extinguishing device. The moving contact is rotatably arranged in the interior of the shell, the operating mechanism is used for controlling the rotation of the moving contact, and the first static contact is fixedly arranged in the interior of the shell. The arc extinguishing device comprises a shell body, a rotating arm, a vacuum bubble and a reset spring, the shell body is fixedly arranged on the shell, the rotating arm is rotatably arranged on the shell body and is provided with an electrically conductive part, the electrically conductive part is arranged on the rotating path of the moving contact, the vacuum bubble is arranged on the shell body, and the two ends of the vacuum bubble are electrically connected with the electrically conductive part and the first static contact respectively, and the reset spring is arranged between the rotating arm and the shell body. When the moving contact is disconnected with the first static contact, the moving contact is electrically connected with the electrically conductive part.
