Charged for replacement 35kV strain insulator string operational methods
Technical field
The present invention relates to a kind of charged for replacement 35kV strain insulator string operational methods.
Background technology
Power circuit passes through insulator(String)It keeps insulating with shaft tower.On tension-resistant rod, on the one hand strain insulator string is wanted
The insulation of conducting wire and shaft tower is kept on the other hand to bear the pulling force of conducting wire.On 35kV circuits, strain insulator string is general
It is made of 3-5 piece strain insulators, is influenced by electric field, outside climatic, insulator loses insulating properties it is possible that failure
Can, become " zero resistance insulator ", if the zero resistance insulator in insulator chain is more than defined quantity, circuit peace will be seriously affected
Full stable operation needs in time to replace zero resistance insulator to ensure power circuit safe operation.35kV circuits are tied because of it
Structure is various informative, and electrical distance is shorter, and mechanical stress is larger, thus traditional replacement 35kV strain insulator strings, mostly uses greatly
Power failure mode is replaced using relevant auxiliary tool.
Currently, the operational method of charged for replacement 35kV overhead distribution strain insulators has been shown in research, such as application No. is
201310141812.3 Chinese patent literature discloses a kind of method, uses transfusion bottle hook assembly, wing type clamp apparatus and standby
The auxiliary tools such as safety device are carried out the replacement of insulator chain in the way of spanner Manual tightening thread-tightening lead screw, there is at 2 points
It is insufficient:First, 35kV circuit stress is larger, the torque that need to be provided is larger, and larger torque to utilize spanner Manual tightening stringing
The operating personnel of lead screw expends larger muscle power, and operating efficiency is not high;Two are to provide for larger torque, may force work
Industry personnel use the spanner of long torque, but 35kV line security distances are smaller, do not allow the operation amplitude of operating personnel excessive,
Otherwise easily cause safety accident.
Up to the present, the moment problem energetically when charged for replacement 35kV strain insulator strings how is solved, it is suitable to there is no
Auxiliary tool and operational method.
