Problems solved by technology

[0003] The suspension and assembly of the "V" insulator in the laboratory is relatively complicated. The conventional suspension method is to use one or two vertically suspended electric hoists to hang a steel cross arm, and connect the two ends of the "V" insulator string. The upper part is hung on the

Abstract

The invention relates to a device for hoisting a V-shaped insulator string, in particular to a V-shaped insulator string suspension device for vibration test of the V-shaped insulator string, which comprises an electric block, V-shaped insulator strings and a V-shaped insulator string assembling fitting, wherein the electric block comprises hoist cranes and a position adjusting block, the V-shaped insulator string assembling fitting is provided with two V-shaped insulator strings, one end of each V-shaped insulator string is hinged onto the V-shaped insulator string assembling fitting, the other end of each V-shaped insulator string is respectively connected with the hoist cranes, the two hoist cranes are symmetrically arranged onto an iron tower upper beam, the hoist cranes are also respectively connected with the position adjusting block, and the iron tower upper beam is parallel to the ground and is used for suspending the V-shaped insulator strings and adjusting an angle between the two insulator strings, so the defect of a suspension method of the V-shaped insulator in an ordinary laboratory can be overcome.

Description

Technical field: [0001] The invention relates to a device for hoisting a "V" type insulator, and more particularly relates to a "V" type insulator string suspension device for a "V" type insulator string vibration test. 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. With the gradual increase of the voltage level of the transmission line, the string length of the insulator string is also gradually lengthened, and the string types are divided into conventional straight strings, strain strings, and V-shaped strings to prevent wind deflection of overhead lines. 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 dif...
