Arc extinguishing type switch device

Abstract

The invention discloses an arc extinguishing type switch device which comprises an insulating shell, a threaded cover and a wiring cylinder, the top of the insulating shell is sleeved with the threaded cover in a threaded mode, a threaded ring is fixed to the middle of the threaded cover in a penetrating mode, a connecting rod penetrates through the middle of the threaded ring in a threaded mode, and a plurality of stirring blades are fixedly installed on the surface of the middle of the connecting rod. The bottom of the connecting rod is sleeved with a rubber disc in a threaded mode. Two wiring cylinders are fixed to the side face of the insulating shell in a penetrating mode, a conducting rod is embedded into one end of each wiring cylinder in a threaded mode, the bottom of the inner wall of the insulating shell extends inwards to form a lining ring, and the bottom of the insulating shell is sleeved with a mounting cylinder in a threaded mode. The insulating shell is filled with conducting media with uncertain shapes and transformer oil, and the liquid level of the conducting media can ascend and descend to immerse the two conducting rods to be connected. The liquid level of the conducting medium rises to immerse the end parts of the two conducting rods, so that the two conducting rods form a current loop, and stable wiring of the two conducting rods can be ensured through a fixed and liquid connection mode.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an arc extinguishing switch device. Background technique [0002] The switch is a basic circuit element and is widely used in circuits. The switch is divided into two states: closed and open. The closed state allows current to pass through, while the open state does not allow current to pass; [0003] At present, when the switch device is disconnected, an arc will be generated when the conductive contacts are separated. The greater the voltage in the circuit, the greater the arc generated when the switch device is disconnected, and the arc is generally extinguished naturally in the air. The generation of the arc causes potential safety hazards, and the connection between the fixation and the fixation often leads to poor contact and unstable wiring. The prior art discloses CN202022181363.3, an intelligent low-voltage switchgear. When the circuit is closed and disconnected, poor ...
