A kind of angle of wind deflection on-Line Monitor Device of transmission line of electricity
Technical field
The present invention relates to a kind of angle of wind deflection on-Line Monitor Device of transmission line of electricity, belong to the remote online monitoring apparatus technology of aerial high-voltage power transmission line.
Background technology
Overhead transmission line is the pith of network system, and transmission line of electricity mainly is made up of shaft tower, lightning rod, lead, insulator chain and gold utensil; The windage yaw discharge of transmission line of electricity is to influence one of factor of the normal operation of circuit; Windage yaw comprises wire jumper windage yaw, alternate windage yaw and insulator windage yaw; The wire jumper windage yaw is meant that the angle tower wire jumper receives big wind effect, makes the reduced distances of wire jumper and angle tower, forms the wire jumper discharge; Alternate windage yaw is meant under the high wind condition that the electrical distance between the lead shortens, and makes between different phase conductors and discharges; The insulator angle of wind deflection angle that to be the suspension insulator that under the wind speed effect, causes become with vertical direction with lead; The insulator chain windage yaw is the main factor that causes the windage yaw discharge accident; The insulator chain windage yaw mainly is because in morphologic region such as hillside, the valley of endangering; Cause the clearance between insulator chain lower end electrified body and the iron tower to reduce easily, when the electrical strength of this gap can not be born system's working voltage, electric discharge phenomena will take place.
The reason of windage yaw flashover has external cause and internal cause, and external cause is inclement weathers such as high wind, hail, rainfall, sand, has reduced the clearance electrical strength between insulator chain and the iron tower, thereby causes the windage yaw discharge; Internal cause is that transmission line of electricity is resisted the high wind scarce capacity, like the dangle weight, diameter of wire of string and deviation is arranged than carry and stress etc. of the difference in height of the span of front and back shaft tower, ruling span, lead suspension point, lead and insulator, the windage yaw discharge can take place also; So the windage yaw of transmission line of electricity discharge is a crucial research topic.
