Description

Auxiliary tool for end surface cementing of composite insulator Technical Field The utility model relates to the field of composite insulator assembly tools in power transmission and transformation equipment, in particular to an auxiliary tool for end surface cementing of a composite insulator. Background Insulators are an indispensable component in an electrical power system, whose main function is to support and insulate conductors while being subjected to mechanical loads and electrical insulation. Among the many types of insulators, porcelain insulators and composite insulators are two common forms. Despite their differences in material and structure, they are all used to achieve the same basic function, namely the glue-fixing of the flange metal piece at the end face of the insulator, to ensure electrical isolation and mechanical support between the insulator and the conductor or ground member. In recent years, composite insulators have gradually replaced porcelain insulators and have rapidly developed due to the materials and structural characteristics of the composite insulators composed of glass Fiber Reinforced Plastic (FRP) mandrels and silicone rubber sheds. However, the composite insulator has higher requirements on the end face gluing quality in the end face gluing process, and technological progress brings forward higher standards on the electrical and mechanical properties of the porcelain bushing in the power transmission and transformation system, which requires that the assembly of the porcelain bushing body and the flange metal piece must have higher concentricity and parallelism. At present, the gluing of flange metal parts of medium-and-large-size insulating porcelain sleeves mainly depends on manual experience, and the special positioning and auxiliary tools are lacked, so that the assembly efficiency is low and the effect is poor. Therefore, in order to meet the high requirements of assembly precision, particularly in terms of electrical performance and mechanical performance, the assembly technology of the composite insulator needs to be further improved to adapt to the requirements of continuous mass production.

As a further limitation, the structural support and the assembly plate frame are both steel plate structures, and form a rigid support with an L-shaped structure, and the rigid support is structurally reinforced between two right-angle sides through triangular rib plates. As a further limitation, the assembly panel bracket is further formed with a guide structure extending along the axial direction of the composite insulator.
