Document Type and Number:
WIPO Patent Application WO/2020/122495
Kind Code:
A1
Abstract:
The present invention relates to an arc extinguishing device of an eco-friendly gas-insulated load break switch, in which a puffer and an arc chute are combined, and to an arc extinguishing device of an eco-friendly gas-insulated load break switch, in which a gas puffer extinguishing scheme that uses mechanically generated compressed gas and an arc chute extinguishing scheme that uses an electromagnetic field principle are mixed, and provides an arc extinguishing device of an eco-friendly gas-insulated load break switch, in which a puffer and an arc chute are combined, the device comprising an enclosure and an extinguishing module mounted inside the enclosure so as to extinguish arc, wherein the extinguishing module comprises: three puffer housings which overlap in parallel so as to connect three phases thereto, and which form an enclosed space with a rotary part; the rotary part which is mounted thereon so as to cross the inside of each of the puffer housings, and on which a movable contact and a rotary piston are mounted thereon so that the movable contact and the rotary piston can rotate in the enclosed space inside the puffer housing; a puffer chamber, which is an enclosed space between the puffer housing and the rotary part; and an arc discharge part comprising the arc chute, which is formed on an upper part of the puffer housing and discharges arc by means of electromagnetic force, and a stationary contact, which is mounted on the rear of the arc chute so as to come into contact with the movable contact.
