Abstract
A direct-current 3kV overall self-cleaning type rigidity section insulator is composed of a pair of bus-bar connectors, a pair of long sliding plates, a pair of short sliding plates and an insulating rod. The two ends of the insulating rod are connected with the inner ends of the pair of bus-bar connectors respectively. The pair of long sliding plates and the pair of short sliding plates are arranged on the two sides of the insulating rod in a staggered mode and fixed to the two sides of the bus-bar connectors, the bottoms of the long sliding plates, the bottoms of the short sliding plates and the bottoms of contact lines are located on the same horizontal face, and the bottom of the insulating rod is slightly higher than the horizontal face. An end portion of each long sliding plate and an end portion of each short sliding plate are overlapped in the transverse direction, a 150+/-10mm air gap exists between each long sliding plate and each short sliding plate in the longitudinal direction, a 150+/-10mm air gap exists between the tips of the two short sliding plates, and a 350+/- 10mm interval exists between the tips of the two long sliding plates. Due to the adoption of the compound insulation rod and the structure that the short sliding plates and the long sliding plates are overlapped, the stability and the reliability of the section insulator are overall improved.
