Description
Technical field：
The present invention relates to power accessories technical field, more particularly to a kind of transmission line antivibration hammer position adjustment dress
Put.
Background technology：
A number of damper is installed on transmission line wire, for eliminating conductor vibration energy, prevent wire by
Cause fatigue stranded in vibration.In use due to the reason such as the height change of vibration, environment, temperature, artificial, it may occur that
Damper loosens offset phenomena so as to not have protective action, in the operation for recovering correct position, it is necessary to real by manual operation
Show, not only complex procedures, also certain human safety issues, especially the damper displacement to 110kV double-circuit lines is powered
Reset work, because combinational gap safe distance problem is hardly possible, the manual reset only under power-off condition.
Harm after damper displacement to wire has at 2 points：First, vibrationproof energy dissipating effect can not be played to wire.2nd, wear
Wire causes serious accident.If damper sliding transfer is to mid span, when the aluminium armor tape of looping on wire blocks vibrationproof
Hammer into shape after sliding to sag minimum point or slide into minimum point, just shaken with the wind on wire, clip rubs with wire, causes to lead
Line serious wear, machinery, electric property are reduced, caused the accident.
Traditional elimination hammer for preventing conductor from vibration displacement method is carried out frequently with manual reset method.By field investigation, we
It was found that manual reset removing method has shortcomings, it is as follows：1st, manual operation realize, not only complex procedures, also have it is certain
Human safety issues.2nd, such as have a power failure and eliminate, then carried out with the plan that has a power failure, it is impossible to timely and effective elimination.3rd, as powered eliminate
Take equipotential rope ladder method is powered to eliminate hammer for preventing conductor from vibration displacement.Group member is had found to the above method by field test：Deng
Current potential rope ladder method can remove damper displacement, but equipotential live line work confined condition is more, many shortcomings 1 be present, can only disappear
Except lower phase conductor damper defect, in upper phase conductor damper defect due to being limited by combinational gap, it is impossible to carry out；2nd, etc.
Current potential operation is easily by inside even from weather, therefore livewire work is had a great influence by weather conditions.
