Special exposure test rack for steel structure of power system

Abstract

The invention relates to a special sunning test frame for a power system steel structure, aiming at monitoring the corrosion conditions of a structure material and an equipment material in the transmission and transformation high pressure and strong electric field environment of a power system. The special sunning test frame comprises a supporting frame and a sunning frame, wherein the sunning frame is installed on the supporting frame with an angle of 45 degrees with the ground, the supporting frame is provided with a vertical bracket and a vertical bracket adjustment device, the sunning frame is provided with a beam, and a specimen is fixed on the beam by virtue of a fixture. According to the special sunning test frame provided by the invention, as a steel structure fixing installation mode is adopted, the atmosphere sunning frame is not fixed on the ground but on the power transmission and transformation equipment steel structure, and the fixing height is adjustable. With the adoption of the special sunning test frame, the atmosphere corrosion speeds in different heights, at different positions and under different electric field intensities can be monitored by virtue of a blade-hanging mode; and the specimen can be directly hung on power transmission and transformation equipment so as to directly monitor the corrosion conditions of the materials of a substation, a transmission line tower and other power transmission and transformation equipment.

Description

technical field [0001] The invention relates to a corrosion status monitoring device for structural materials and equipment materials under high-voltage and strong electric field environment of power system power transmission and transformation, in particular to a special exposure test frame for steel structure of power system, which belongs to the technical field of UHV power transmission and transformation. Background technique [0002] As an effective method to evaluate and study the atmospheric corrosion of materials, atmospheric corrosion exposure has been widely used in many scientific research and engineering fields. But at present, all the atmospheric exposure devices and atmospheric sample hanging devices are general-purpose, that is, on the ground, in the shutter box or in the exposure field. With the rapid development of my country's electric power industry and the continuous expansion of the scale of various cities and towns, 220kV transmission lines have become ...

Problems solved by technology

This kind of corrosion is different from the traditional atmospheric corrosion. Due to the strong electric field, the continuous discharge of the power supply line will greatly increase the ionic strength and corrosive components of the atmospheric environment in the strong electric field area.
