Power industrial service is in the important mission built a harmonious socialist society.
Waving for super-high voltage road multiple division electricity transmission line is low with frequency, and amplitude is big, at one or n half in span
The feature of waveshape.Typical super-high voltage road, waving frequency is 0.15Hz~1Hz, and waving amplitude is span inside conductor arc
Vertical 0.1~1 times.
The extent of injury of conductor galloping depends on the severity of conductor galloping, waves the structure of duration and conducting wire
Form.The harm of transmission line galloping has: flashover causes system circuit breaker disconnection and wire arc to be burnt, including conducting wire destruction,
Conducting wire distance to the ground deficiency, steel tower loosened fastener, accumulative wave cause steel tower fatigue rupture, fatigue rupture at strain insulator-string, jump
Caused by line fatigue rupture, conductor spacer and damper damage, insulator chain destruction and the effect of split conductor failure balanced balanced current
Conducting wire is stranded at suspension clamp and conductor spacer.
The more cracking separation rod stabilities of the power equipment being widely used on transmission line of electricity are poor, intensity is poor and prevents
