The invention provides a hot airflow exhaust device for an arc extinguish chamber, the arc extinguish chamber and a gas insulated switch. The hot airflow exhaust device comprises: a static contact seat which is suitable for being connected or disconnected with a movable contact seat of an arc extinguish chamber so as to realize connection or disconnection of a circuit; a static end support which is suitable for being in sealing fit with an insulating supporting part on a shell of the arc extinguish chamber; and a combination part which is arranged between the static contact seat and the static end support, wherein a through hole is formed in the combination part, the through hole is suitable for an arc striking contact on a movable contact seat of the arc extinguish chamber to pass through, the static end support comprises a cylindrical body with a hollow cavity, the first end of the cylindrical body ends at the combination part, the second end of the cylindrical body is suitable for being matched with the insulation supporting part in a sealing mode, a plurality of air holes penetrating through the circumferential side wall are formed in the circumferential side wall of the cylindrical body, so that hot airflow generated after a circuit is disconnected in the arc extinguish chamber is led into the hollow cavity from the arc striking contact and is directly discharged from the plurality of air holes. The hot airflow exhausting device is simple in structure, and exhausted hot airflow is easy to cool.
Description
technical field [0001] The present invention relates generally to the field of electrical equipment, and more particularly to hot gas exhausts for arc chute, arc chute and gas insulated switchgear. Background technique [0002] The arc extinguishing chamber is the core component of the high-voltage power switch. It is used to quickly extinguish the arc after the high-voltage circuit is cut off through the excellent insulation of sulfur hexafluoride gas, cut off the faulty circuit, prevent the accident from expanding, ensure safe operation, and avoid accidents and accidents. Accidents happen. [0003] For the traditional hot air exhaust device used in the interrupter, it usually includes static end support, exhaust pipe, cover, air guide nozzle, guide cone, static contact seat and other components. When the three-phase interrupter is disconnected from the circuit, the high-speed hot air flow is ejected from the driven end, first to the exhaust pipe and the air guide nozzle, ...
