Description

Technical Field

[0001] The invention relates to the technical field of insulator processing, in particular to an electric porcelain insulator assembly device. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Insulators are a special type of insulating control component that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for electric poles, and gradually developed into high-type high-voltage electric wire connection towers with many disc-shaped insulators hung at one end. It is to increase the creepage distance. It is usually made of glass or ceramics, which is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulators will not play a significant role and will damage the use and operation life of the entire line.

[0003] In the process of production, insulators are usually assembled from a porcelain part and a hardware part. The production process of porcelain insulators can be divided into five parts: clay making, molding, glazing, firing, assembly and inspection. Assembly refers to the assembly of steel caps, steel legs and porcelain parts after the porcelain insulators are fired, and then inspected through mechanical tensile tests, electrical tests, etc.; assembly should ensure the coaxiality of the insulator steel caps, porcelain parts and steel legs, and the filling degree of the glued parts. If the coaxiality does not meet the requirements, it will lead to uneven force inside the insulator after commissioning, causing slippage or even string breakage. If the filling degree does not meet the requirements, an air gap will be left inside the insulator, which is prone to internal breakdown and string breakage under overvoltage; in the assembly process, the existing technical means are difficult to conduct comprehensive inspections on the batch insulators produced, and batch sampling is usually used for inspection. Therefore, it is necessary to design an assembly equipment and method that can monitor the produced insulators one by one to further improve the overall quality of assembled insulators.
