Problems solved by technology

However, this solution often brings new problems to the test. First, the insulation problem must be considered when setting up the tension frame or using the existing structure, that is, a series of insulation length and creepage must be connected between the tension point and the end of the insulator string. The electrical distance is far greater than the insulators of the test insulator string, which undoubtedly puts forward greater requirement

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a device for simulating the arrangement of tension insulator strings and a method for using the same. Background technique [0002] In order to study the electrical characteristics of insulator strings, researchers often carry out electrical characteristic tests such as simulating pollution, icing, and lightning shock of insulator strings of different string types and materials in laboratories (indoor or outdoor). Because the two ends of the tension insulator string are affected by the tension of the wire in the project, the angle between the axis of the insulator on both sides of the suspension point of the tension insulator string and the vertical direction is relatively large, and the tension insulator string is arranged in an inverted V shape. During the test, it is often necessary to set up a tension frame in advance, or select a tension point ...
