Description

A device for installing a conductive rod

technical field

The utility model relates to the technical field of installation devices for conductive rods, and is especially suitable for the assembly process of high voltage, extra high voltage and ultra high voltage bushings. the

Background technique

At present, as the voltage level of high-voltage electrical equipment increases, the creepage distance and insulation distance of the incoming and outgoing porcelain bushings (composite bushings) also increase, and the diameter and length of the corresponding porcelain bushings also increase. The diameter of the million-volt incoming and outgoing porcelain bushing is more than one meter, and the length is more than ten meters long. When the conductive rod is installed in the porcelain bushing of this length, there is a phenomenon that the conductive rod "bows its head". There are two general solutions: one method is to directly add a flexible material to the end of the conductive rod. The sheath is used to contact the inner wall of the casing with the sheath. Although the structure of the sheath is simple in this method, there is a large friction between the sheath and the porcelain casing. When the sheath moves with the conductive rod, the conductive The end of the rod is often exposed from the sheath, so that the protection of the sheath to the conductive rod is not in place, so that the end of the conductive rod will directly contact the inner wall of the porcelain sleeve, and eventually cause the inner wall of the porcelain sleeve to be scratched; One method is to use a small pulley inside the bushing to hold the conductive rod to prevent the end of the conductive rod from colliding with the inner wall of the bushing. This method is simple, but when in use, the small pulley can only prevent the end of the conductive rod from colliding with the inner wall of the bushing. Bumping against the inner wall of the porcelain bushing does not help the centering and positioning of the conductive rod. In the subsequent assembly work, other means are needed for auxiliary centering and positioning, which increases the labor intensity of the conductive rod assembly. the

The Chinese utility model patent with the notification number CN202363840U discloses a guide car for GIS three-phase common box busbar conductive rod tooling. Through the coaxial connection of the connecting rod extending front and back, a conductor hole for the conductive rod to be installed is opened on the guide body and the positioning plate, and several small rollers are evenly distributed on the hole wall of the conductor hole. There are several large rollers on the outer circumference of the body, so that the guide body can slide coaxially into the inner hole of the bus barrel through the big rollers, so as to ensure that the conductor holes on the guide body and the positioning plate are opposite to the contact seats on the disc insulator on the bus barrel. However, with the continuous increase of the diameter of the bus barrel, the diameters of the guide body and the positioning plate on the corresponding guide car also need to be increased accordingly, so that the whole guide car becomes cumbersome, and the installation of conductive wires in the bus barrel is increased. The amount of labor and work difficulty of the pole will reduce the work effect. the
