Fixable high-voltage test insulating rod

The invention provides a fixable high-voltage test insulating rod. The invention comprises a test section, an expansion joint, a fixed joint and a fixed tripod, wherein the test section, the expansion joint and the fixed joint are sequentially connected in a working state, and the three have insulating performance. According to the invention, the number of the expansion joints can be adjusted according to requirements, so that the expansion joints can be shortened and lengthened freely, and the requirements of different experiments can be met. According to the invention, the defects of unstable support, poor safety, inconvenient carrying and difficulty of the on-site high-voltage test insulating rod are well solved, and the safety, efficiency and accuracy of the on-site test are greatly improved.
