Background
More and more areas passing through the severe conditions of the overhead transmission line are not only attacked by rainstorm and thunder, but also affected by strong wind, and the insulator string swings greatly, so that the probability of wind deflection flashover is greatly improved. Once windage yaw flashover occurs, the success rate of superposition of the power transmission network is low, and is about 25% according to relevant literature display, so that large-area power failure accidents are caused, great harm is brought to life and production of people, and great economic loss is brought to the country. And after windage yaw accidents occur, the occurrence place of the fault is difficult to accurately and quickly judge, and great troubles are brought to the operation and maintenance work of the high-voltage transmission line.
The wind deflection comprises jumper wire wind deflection, interphase wind deflection and insulator wind deflection, and the jumper wire wind deflection means that a jumper wire of the corner tower is influenced by strong wind, so that the gap between the jumper wire and the corner tower is shortened, and jumper wire discharge is formed; the interphase wind bias means that the electrical distance between the wires is shortened under the condition of strong wind, so that the wires of different phases are discharged; the insulator windage yaw generally refers to the inclination angle of an insulator string relative to a linear tower under the action of wind power. Among them, the wind deflection of the insulator string is the most main factor causing the wind deflection trip accident.
The direct reason for the occurrence of the wind deflection tripping accident is that the wind deflection angle of the suspension insulator string is too large, the air gap between a charged body at the lower end of the insulator string and an iron tower is easily reduced when the wind deflection angle is too large, and the flashover phenomenon can occur when the electrical strength of the gap cannot bear the operating voltage of a system. Therefore, the air gap between the wire and the iron tower is not over-limited under severe meteorological conditions such as sand storm and the like, and the method is a main means for preventing windage yaw flashover accidents. There is therefore a need for a new suspension insulator string pattern to prevent windage flashover accidents.
