Description

Technical Field

[0001] The utility model relates to the technical field of insulating basins, in particular to a vacuum heat-insulating insulating basin. Background Art

[0002] The pot insulator is generally made of insulating parts (such as porcelain parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued or mechanically clamped. Insulators are widely used in power systems. They are generally external insulation and work under atmospheric conditions. The busbars of overhead transmission lines, power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth (or grounding objects) or other conductors with potential differences.

[0003] In order to meet the requirements of casing grounding, additional guide bars need to be added to the shells of the components on both sides of the insulating basin. When installing the guide bars, the paint on the component shell that is in contact with the guide bar installation surface needs to be removed to ensure good electrical connection, or the contact parts need to be processed before the component shell is painted so that the metal parts can be reserved and exposed.

[0004] This increases the workload of on-site installation or the process and complexity of painting. In addition, in some application scenarios, the shape of the shells on both sides of the insulating basin limits the possibility of adding a cross-connected guide bar. Utility Model Content
