The testing system comprises insulator strings, an insulation string suspension device, two anchoring devices, an electromagnetic vibration platform, a split conductor, a force transducer and a measurement and control device, wherein the two anchoring devices are arranged on the horizontal surface through a support and connected through the split conductor, the electromagnetic vibration platform is also arranged between the two anchoring devices, and the electromagnetic vibration platform is connected with the split conductor; the suspension insulator string is connected to the split conductor between the electromagnetic vibration platform and one anchoring device, and the strain insulator string is arranged between the electromagnetic vibration platform and the other anchoring device; and the electromagnetic vibration platform and the force transducer are also connected with the measurement and control device simultaneously. The testing system disclosed by the invention can be used for finishing a vibration creep test of the suspension insulator string and the strain insulation string in the field of high-voltage transmission and transformation.

Description

Technical field: [0001] The invention relates to the field of high-voltage power transmission and transformation, and more particularly relates to a test system for vibration tests of insulator strings. Background technique: [0002] In the field of high-voltage power transmission and transformation, insulator strings are used to connect overhead transmission lines and iron towers and provide insulation between them. In the early stage of line design, it is necessary to do power frequency or DC wet withstand test, lightning shock dry withstand test, operation shock wet withstand test, corona and radio interference test, vibration creep, etc. in the laboratory for different string insulators. Relevant electrical and mechanical performance tests. Among them, the vibration creep performance test is to apply an alternating load with a vibration frequency close to the actual line breeze vibration on the insulator string, and the number of continuous vibrations exceeds 10 million...
