Description
Technical field
The present invention relates to a kind of damper bolt disassembly device, particularly a kind of damper bolt disassembly method.
Background technology
When overhead transmission line is acted on by stable and little gentle breeze, more than one will be produced in the lee face of ground wire
The air-flow vortex that certain frequency changes alternatively up and down, the air-flow vortex makes overhead line by the impulsive force of alternation up and down.Work as air-flow
When the alternating change frequency of vortex is equal with the intrinsic natural frequency of vibration of overhead line, resonance is produced in vertical plane, that is, causes frame
The vibration of ceases to be busy.The aeolian vibration of overhead line is that what is often occurred have the vibration of harmfulness, and the safe operation to circuit is threatened very
Greatly.Vibration makes overhead line " fatigue " phenomenon occur, causes that overhead line is stranded, even break.To prevent overhead line aeolian vibration, one
As after built on stilts linear diameter, the situation of local wind speed is combined, be easiest to occur near the wire clamp of overhead line by calculating to find
The position of " fatigue ", installs a number of damper.When wire vibrates, the weight at damper two is because inertia
It is relative to move up and down, the energy of vibratory overhead line is consumed, reduces the amplitude of overhead line, vibration is limited in non-hazardous scope,
So as to avoid overhead line fatigue stranded.
But after damper is installed, because the situation that damper is damaged, shifted occurs in many reasons, not only vibrationproof can not be played
Effect, or even can fray, rub overhead line.Therefore, the damper for damaging or shifting must be changed as early as possible.Mainly pass through at present
Livewire work or the progress that has a power failure, traditional work mode are that personnel's seating ground wire driving outlet is overhauled.
There is some following deficiency in traditional maintenance mode：
（1）The master operation for changing damper operation requires that operation is finer and smoother, and conventional earth potential working instrument can not be met
Its job requirements.Therefore, equipotential live line work mode is generally used at present, and entering electric field equipotential by operating personnel carries out maintenance work
Industry.Equipotential live line work one is the presence of larger danger, operating personnel's labor intensity greatly, have to the quality of operating personnel compared with
High requirement, operating risk is high；Two be part compact shaft tower, wire vertical arrangement or the situation for having scissors crossing, powered work
Industry insufficient space, it is impossible to meet job requirements, need to have a power failure processing.
（2）Power failure operation equally exists the shortcoming that operating personnel's labor intensity is big, operating risk is high.In addition, if stopping
Electric treatment, one is that can influence power supply reliability, and two be due to have a power failure to have brought sth. into the plan management, defect processing it is sudden with it is timely
Property with have a power failure it is planned can produce contradiction, tend not to handle damper defect in time, existing defects continue development so that danger
And the risk of line security operation.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, and provide a kind of achievable livewire work, energy
