Seismostation test device for power transmission tower line system

Abstract

The invention relates to a seismostation test device for a power transmission tower line system, and the power transmission tower line system comprises a vertical tower body and model towers disposed at the upper end of the tower body in a lateral direction and composed of a tower head. The device comprises an equivalent tower parallel to the model towers, and a fixed base disposed at the lower end of the equivalent tower. The number of the model towers is three or more, and each model tower is connected through two steel strand layers disposed at the top. The upper steel strand passes through the equivalent tower to be fixedly connected with the fixed base, and the lower steel strand is a strand connected with an I-shaped insulating string or a V-shaped insulating string, and two ends of the lower steel strand are respectively connected with the equivalent tower. Compared with the prior art, the device provided by the invention gives full consideration to the boundary condition, so as to truly reflect the stress state of a tower line system or a single tower, to improve the application range, and reduce the cost.

Description

technical field [0001] The invention relates to a seismic table test device, in particular to a seismic table test device for a power transmission tower line system. Background technique [0002] The transmission tower is the pillar of power transmission, and its safety and reliability directly affect the safety and operation of the entire power system. When an earthquake occurs, the transmission tower will be damaged or even collapsed, which will affect social life, bring economic losses, and then affect the development of the national economy. Therefore, a seismic table test device for the transmission tower line system is needed to detect the seismic performance of the transmission tower during geological disasters such as earthquakes. [0003] The vibration detection device of the existing transmission tower only detects the anti-seismic performance of one transmission tower, ignoring the mutual influence between the transmission tower and the transmission tower, and be...

Problems solved by technology

[0003] The vibration detection device of the existing transmission tower only tests the anti-seismic performance of one transmission tower, ignoring the mutual influence between the transmission tower and the transmission tower, and between the transmission tower and the ground wire

The following problems will be involved: ①The boundary conditions of the transmission tower are ignored, and the real force state of the transmission system or single tower cannot be truly reflected, which affects the detection data

②Transmission towers are tower-line-tower-line-tower and so on. The transmission tower test should not only have a single tower, but also consider the wires on both sides of the tower and adjacent towers, which cannot truly reflect the high-voltage transmission lines and towers. Dynamic characteristics and seismic response of solid structures under earthquake action

③The cost of transportation and testing is high and the construction schedule is difficult to control

④ Not suitable for areas with steep mountain roads, lack of construction materials, and large-scale construction machinery handling and work
