According to the conducting rod assembling tool, the distances between the three supporting plates are adjustable, the space defined by the three supporting plates can be large or small, and the conducting rod assembling tool is suitable for assembling conducting rods of bus tubes of different diameters.

Description

technical field [0001] The invention relates to the field of assembly of high-voltage, ultra-high-voltage, and ultra-high-voltage pipeline busbars, in particular to a process device for installing inlet and outlet bushings and conducting rods in pipeline busbars. Background technique [0002] 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 casing of this length, there is a phenomenon that the conductive rod "bows its head", and there are two general solutions: one method is to directly add a sheath made of flexible material to the end of the...

Problems solved by technology

When the conductive rod is installed in the porcelain casing of this length, there is a phenomenon that the conductive rod "bows its head", and there are two general solutions: one method is to directly add a sheath made of flexible material to the end of the conductive rod , use the sheath to contact the inner wall of the casing. 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 end of the conductive rod The part 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; another method It is to use a small pulley to support the conductive rod inside the casing to prevent the end of the conductive rod from colliding with the inner wall of the casing. Although this method is simple, the small pulley can only prevent the end of the conductive rod from colliding with the porcelain when in use. The inner wall of the casing cannot help the centering and positioning of the conductive rod, and other means are needed to assist centering and positioning in subsequent use, which increases the labor intensity of the conductive rod assembly

[0003] The Chinese utility model patent whose notification number is CN202363840U discloses a kind of guide car for GIS three-phase common box busbar conductive rod tooling. The positioning plate is coaxially fixed by the connecting rod extending from front to back. On the guiding pole and the positioning plate, there is a conductive rod hole for the conductive rod to be installed to pass through. Several small holes are evenly distributed on the hole wall of the conductive rod hole. There are several large rollers on the outer circumference of the guide pole. Through the large rollers, the guide pole slides coaxially into the busbar tube to ensure that the guide pole and the conductive rod hole on the positioning plate are in line with the disc insulator on the busbar barrel. The contact seat is opposite, but because the conductive rod hole for the conductive rod to be installed is fixed on the guide pole and the positioning plate, this limits that a set of guide vehicles can only be used for diameters and through holes. When the diameter of the conductive rod is smaller than the diameter of the through hole, although the conductive rod can be fixed by adding fillers in the through hole, this will greatly reduce the centering accuracy of the conductive rod. In order to be suitable for the assembly of conductive rods with different diameters, manufacturing multiple sets of guide vehicles increases the cost of use
