Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware equipment, in particular to a discharge gap ring for a gap electrode component. Background Art

[0002] Most of the overhead insulated lines are subject to induced lightning strikes. When the lightning overvoltage flashes over, since the overvoltage protector is connected in parallel with the line insulator, the lightning current causes a high potential to cause the series gap of the lightning arrester to operate, reducing the potential difference between the tower arm and the conductor, ensuring that the insulator no longer flashes over, thereby avoiding line tripping and power outages. In order to ensure the normal operation of the overvoltage protector, the appropriate distance between the gap ring and the insulated conductor must be ensured;

[0003] Existing Chinese patent document CN202221433519.5 discharge gap ring, relates to the field of power hardware technology. It includes an upper half ring and a lower half ring, the upper half ring and the lower half ring are enclosed in a circular ring shape, the upper half ring and the lower half ring are both provided with a connecting rod, the connecting rod is connected to the mounting member, the connecting rod is provided with a locking mechanism, the locking mechanism is used to lock the mounting member and the connecting rod; the locking mechanism includes an upper pressing plate and a lower pressing plate, the mounting member passes through the upper pressing plate and the lower pressing plate, the mounting member is provided with a pair of nuts, one nut is located at the top of the upper pressing plate, and the other nut is located at the bottom of the lower pressing plate; the mounting member is set biased to the left side of the upper pressing plate, there is a gap between the upper pressing plate and the lower pressing plate, the connecting rod is inserted from the right side of the gap and close to the mounting member. The utility model avoids the displacement of the connecting rod after long-term use, causing the change of the gap between the upper half ring and the lower half ring, and ensures the reliability of gap discharge.

[0004] However, the above patent has certain defects when in use. The dirt attached to the surface of the gap ring forms a conductive film on the insulating surface under humid conditions, which greatly reduces the insulation level of the insulator. Strong discharge occurs under the action of the electric field, causing flashover accidents. Utility Model Content
