Problems solved by technology

[0003] For the existing three-post insulator test devices, most of them focus on the mechanical tension and fracture stress of the three-post insulator, often ignoring the check of the vibration mechanical strength of the three-post insulator
At the same time, the influence of temperature on the three-post insulator is rarely considered in the test device
Therefore, the mechanical strength check of the three-post insulator is not comprehensive, and it is necessary to study the three-post insulator for vibration factors

Abstract

The invention discloses a variable-temperature three-post insulator vibration simulation test device. In the variable-temperature three-post insulator vibration simulation test device, a three-post insulator is fixed on a supporting platform through a fixing structure, and a ceramic heating ring surrounds the three-post insulator to simulate the environment temperature. A temperature control device is connected with the ceramic heating ring to adjust the simulated environment temperature, a connecting structure is connected with the three-post insulator in multiple directions, and a vibration exciter excites the three-post insulator in a preset direction through the connecting structure.

Description

technical field [0001] The invention relates to the technical field of three-pillar insulator tests, in particular to a variable-temperature vibration simulation test device for three-pillar insulators. Background technique [0002] Three-post insulators are widely used in power transmission systems as insulating support structures. It is exposed to the outdoors, the working environment is harsh, and it often faces drastic changes in temperature. Moreover, the vibration caused by environmental and other factors intensifies the test of the mechanical strength of the insulator. High-frequency vibration will cause the deterioration of local defects, so that small defects may also cause major accidents. In recent years, the three-pillar insulators have broken due to mechanical strength problems. Even broken accidents are not uncommon. Therefore, it is of great significance to evaluate the influence of temperature and vibration coupling on the three-post insulator and obtain th...
