Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transformer equipment, and in particular to a transformer composite insulating glue-impregnated paper bushing, an installation device and an installation method. Background Art
[0002] Transformer bushing is an important component of the transformer. The main function of the transformer bushing is to provide electrical insulation, protect the transformer's output cables and insulators, and prevent electrical faults or short circuits.
[0003] Transformer bushings are divided into many types, such as long and short types, and are used in a variety of different scenarios and locations. When installing, some transformer bushings are installed horizontally to the side of the L-shaped plate, and some are installed vertically on the upper end face of the L-shaped plate. During installation, one end of the transformer bushing is usually equipped with a flange with holes opened on the flange. These holes are used to correspond to the through holes on the L-shaped plate. The staff will pass the screw through the flange and the L-shaped plate in turn, and then use the nut to screw it onto the screw to complete the fixation of the other flange and the L-shaped plate, and then fix the transformer bushing to the L-shaped plate.
[0004] With regard to the above-mentioned related technologies, when fixing the transformer bushing horizontally on the L-shaped plate, the staff usually needs to support the transformer bushing with their hands or other equipment, and then place the transformer bushing on the L-shaped plate to be connected, and then align the hole of the flange with the through hole of the L-shaped plate, and then fix it with bolts. It is difficult to align the through holes, and the staff needs to spend more time to align the hole positions. Moreover, when inserting the bolts for fixing, if the support of the transformer bushing is unstable, it will also cause the transformer bushing to be displaced, and the position of the transformer bushing will need to be adjusted later. In addition, the manpower or material resources consumed in supporting the transformer bushing are large, and the convenience of installing the transformer bushing is low. Summary of the Invention

[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. When installing the sleeve, move the connecting flange to the L-shaped plate where it is to be connected, then rotate the sleeve. When the connecting hole is aligned with the through hole, the through-post is inserted into the through hole. The worker can directly install the bolt into the connecting hole without the through-post. The bolt is passed through the connecting hole and the through hole to fix the connecting flange and the L-shaped plate. The structure is simple and the installation is convenient. When installing the bolt, there is no need to hold the sleeve by hand, thereby improving the convenience of sleeve installation and saving manpower.
[0028] 2. Move the connecting flange to the L-shaped plate where it is to be connected. If the connecting hole is not directly aligned with the through hole, move the through-post away from the L-shaped plate. As the sleeve is rotated to align the connecting hole with the through hole, the through-post passes through the L-shaped plate under the action of the restoration part, thereby supporting the sleeve on the L-shaped plate. Workers do not need to support the sleeve manually, thereby improving the convenience of sleeve installation and saving manpower.
[0029] 3. After the through-column passes through the L-shaped plate, install a nut at the end of the through-column away from the extension rod, and then clamp the L-shaped plate and the connecting flange between the nut and the extension rod to complete the initial fixation of the L-shaped plate and the sleeve. The structure is simple and the convenience of fixing the connecting flange is high;
[0030] 4. Before installation, the side wall of the casing can be first placed tightly against the installation groove, and then the casing can be clamped by sliding the support plate. The mounting bracket can then be installed on the L-shaped plate. Workers do not need to manually support the casing, saving manpower. At this time, the through-post moves away from the L-shaped plate, and the mounting bracket slides to the connection point of the L-shaped plate. If the connection hole is not directly aligned with the through hole, the casing can be easily rotated by rotating the casing under the action of several rotating rollers. As the casing rotates and the connection hole is aligned with the through hole, the through-post passes through the L-shaped plate under the action of the restoration part, and then the casing is supported on the L-shaped plate. Workers do not need to manually support the casing, thereby improving the convenience of casing installation.
[0031] 5. When installing the mounting bracket on the L-shaped plate, place Plate 2 on the upper end surface of the L-shaped plate and use the abutment hook to hook the upper end surface of the L-shaped plate. At this time, the upper end of the L-shaped plate is located between the abutment balls. Then place Plate 1 on the side of the L-shaped plate and slide the abutment part to hook the mounting hook on Plate 1 on the side of the L-shaped plate. At this time, the side of the L-shaped plate is located between the abutment balls. The mounting bracket is installed. The structure is simple and the installation is convenient.
[0032] 6. When adjusting the sleeve, the connecting flange can be rotated by pulling the adjusting rod, thereby aligning the connecting hole with the through hole. The structure is simple and easy to drive.
[0033] 7. By operating the piston rod of cylinder one to extend and retract, the first part can be driven to move, thereby completing the installation and removal of plate one. By operating the piston rod of cylinder two to extend and retract, the support plate can be driven to move, thereby completing the clamping and loosening of the casing. The structure is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
