Problems solved by technology

[0002] The outdoor high-voltage AC grounding switch plays the role of opening and closing the transmission line in the transmission of electricity, so the outdoor high-voltage AC grounding switch is an important power equipment, and the 252KV outdoor high-voltage AC grounding switch is one of the commonly used equipment. Expansion and continuous improvement of capacity, outdoor high-voltage AC grounding switches that open and close super B class are widely used. The higher the voltage is, the easier it is to burn the contact fingers and cause equipment failure when the device is opened and closed. This requires the release of induced current to avoid it. At present, the device for releasing the induced current has not been used in the 252KV open and close ultra-B class outdoor high-voltage AC grounding switch

Abstract

The invention relates to an induced current release device of a 252KV switching extra-B-type outdoor high-voltage alternating-current earthing switch. The induced current release device comprises an auxiliary moving contact, an arc extinguish chamber, a drive device and an on-off device. The arc extinguish chamber is disposed on the outer side of the rear end of a master earthing knife. A silicone insulator is perpendicularly disposed on the outer side of the maser earthing knife. The auxiliary moving contact is hinged to the silicone insulator. The front end of the arc extinguish chamber is connected with the auxiliary moving contact through a flexible conductor. The on-off device comprises a connecting plate and a transmission link. The drive device comprises a pull plate, an adjusting sleeve, a moving contact pull rod, a turning crank, and a torsion spring spindle. The induced current release device has the advantages of simple and reasonable structure, stability in transmission and high safety.

Description

technical field [0001] The invention relates to the technical field of an outdoor high-voltage AC grounding switch, in particular to a device for releasing induced current used in a 252KV open-close super-B class outdoor high-voltage AC grounding switch. Background technique [0002] The outdoor high-voltage AC grounding switch plays the role of opening and closing the transmission line during power transmission, so the outdoor high-voltage AC grounding switch is an important power equipment, and the 252KV outdoor high-voltage AC grounding switch is one of the commonly used equipment. Expansion and continuous improvement of capacity, open and close outdoor high-voltage AC grounding switches of super B class are widely used. The higher the voltage is, the easier it is to burn the contact fingers and cause equipment failure when the device is opened and closed. This needs to be avoided by releasing the induced current. At present, the device for releasing the induced current h...
