Abstract

The invention discloses a change tool for an ultra-high-voltage strain insulator string. The change tool comprises a hanging board connecting fitting, a yoke plate clamping fitting, a pulley assembly and a tightener, wherein the hanging board connecting fitting is used for connecting two strain regulating hanging board mounted on a tower body, the yoke plate clamping fitting is clamped on a strain yoke plate mounted on a circuit, the pulley assembly is connected between the hanging board connecting fitting and the yoke plate clamping fitting, and the tightener provides tightening force for the pulley assembly. The invention further discloses a change technology for the ultra-high-voltage strain insulator string. The technology comprises the following steps: connecting the two strain regulating hanging board mounted on the tower body by the hanging board connecting fitting to provide a first pivot; clamping the yoke plate clamping fitting on the strain yoke plate mounted on the circuit to provide a second pivot; mounting the pulley assembly between the first pivot and the second pivot through the tightener and a rope so as to reduce tightening force. The change tool and the change technology are suitable for changing the insulator string.

Description

technical field [0001] The invention relates to the field of replacement of insulator strings, in particular to a tool for replacing an entire string of UHV tension-resistant insulators and a replacement process thereof. Background technique [0002] At present, with the rapid development of the power industry, UHV AC transmission technology is becoming more and more mature, and its corresponding voltage level is also getting higher and higher, which has leapt from the original 500kV to 1000kV. However, with the increase of the voltage level, the tonnage of the insulator strings used on UHV AC transmission lines is also increasing, so there are the following problems in actual construction and maintenance: [0003] Since the tonnage of the insulator string has jumped from the original 21T to 56T, and the corresponding replacement tools are still 24T, the original insulator replacement tools can no longer meet the actual needs. Contents of the invention [0004] The object...
