Abstract

The invention discloses a seismic test device and test method for an ultrahigh-voltage direct current single-pole composite post insulator. The seismic test device for the ultrahigh-voltage direct current single-pole composite post insulator comprises a vibrating table, a support installed on an installation platform of the vibrating table and a single-pole post insulator with the lower end installed on the installation platform of the support, wherein a counterweight is arranged at the upper end of the single-pole post insulator, a hardware fitting is arranged at the upper end of the counterweight, and at least one accelerometer and at least one strainmeter are arranged on the installation platform of the support; at least one accelerometer, at least one strainmeter and at least one displacement meter are arranged on the single-pole post insulator; at least one accelerometer is arranged on the hardware fitting; and at least one displacement meter is arranged on the installation platform of the vibrating table. The seismic test device and test method for the ultrahigh-voltage direct current single-pole composite post insulator are low in test cost, and can be used for effectively assessing the seismic performance of the single-pole post insulator.

Description

technical field [0001] The invention relates to the technical field of substation equipment, in particular to an anti-seismic test device and a test method for an UHV DC single-column composite post insulator. Background technique [0002] With the development of my country's power transmission and transformation projects in the direction of high voltage, ultra-high voltage and ultra-high voltage, a large number of key substations are equipped in AC substations and DC converter stations. These key substations are generally supported by post insulators. Traditionally, the pillar insulators used in substations are mostly made of ceramic materials. Ceramic materials are brittle materials with a large elastic modulus, but poor impact resistance and ductility. Once tiny cracks are formed inside, it is easy to cause earthquakes Brittle fracture damage, and then cause damage to substation equipment. In recent years, composite post insulators have been gradually accepted and put in...
