Abstract

The invention discloses an insulator fatigue test device and relates to the technical field of insulators. The device comprises a first steel frame, a second steel frame, an insulator, a steel strand,a vibration device and a tensioning device. A first end of the insulator rotates relative to the first steel frame, a second end of the insulator is fixed to a first end of the steel strand, a secondend of the steel strand is fixed to the second steel frame, the steel strand penetrates through the vibration device and the tensioning device, and the vibration device is located between the insulator and the tensioning device. According to the invention, the insulator load and the vibration frequency and amplitude of the steel strand can be adjusted as required such that fatigue tests of different degrees can be used, and the applicability range is wide.

Description

technical field

[0001] The invention relates to the technical field of insulators, in particular to an insulator fatigue test device. Background technique

[0002] Porcelain insulators are composed of various materials such as ceramics, metals, and cement. They play a role in fixing and supporting wires in power transmission lines, and ensure sufficient electrical insulation between wires and high-voltage wire supports in power transmission lines. The vibration fatigue performance of insulators closely affects the bearing capacity and insulation resistance of insulators, which is related to the operation safety of transmission lines. Therefore, it is necessary to conduct vibration fatigue tests on insulators to determine the influence of vibration fatigue on the deterioration and zero-value defects of porcelain insulators. However, the existing insulator fatigue test device is too large and complex, and its work efficiency and adaptability are low.

[0003] Therefore, the g...
