Description
Technical Field
The utility model relates to the technical field of electric power engineering, in particular to an unmanned aerial vehicle water spraying assembly for hydrophobicity detection of a line insulator.
Background
Under the action of a strong electric field, sunlight irradiation, humidity, dirt, acid rain and the like, a silicon rubber material of the line insulator is aged, the hydrophobicity is reduced, even disappears, dirt accumulation is intensified, discharge such as corona and electric arc is generated, the leakage current is increased, the aging process of the line insulator is intensified by corona and electric arc discharge, and the like, so vicious circle is realized until serious accidents occur, and the safe operation of a power system is influenced.
The line insulator has hydrophobicity, the surface of the line insulator is condensed to form discrete liquid drops in a dirty and wet environment and the discrete liquid drops and the surface dry areas are alternately arranged, so that the surface electric field of the insulator is distorted, and when the electric field intensity of the dry areas among the liquid drops reaches the breakdown electric field intensity of air, the insulator can generate intermittent local discharge under the condition of very low voltage. The presence of the discharge arc reduces or even loses the hydrophobicity around the droplet, accelerating the development of a local arc and eventually forming a flashover. Due to the influence of factors such as dirt, moisture, discharge, low temperature and the like, the surface of the running line insulator can be seriously stained or aged, so that the surface hydrophobicity of the insulator is poor to cause insulation. In humid weather such as overcast and rainy, the surface insulation strength is sharply reduced, so that flashover along the surface is likely to occur, and pollution flashover is caused. The pollution flashover accident often causes large-area and long-time power failure, so that the economy is seriously lost. The anti-pollution flashover capability of the insulator can be well mastered by detecting and judging the hydrophobicity, so that the insulator can be maintained in time to prevent accidents.
The following three common hydrophobic property testing methods are available:
1. contact angle method: the method for characterizing the hydrophobicity is characterized in that the hydrophobicity state of the line insulator is characterized by a contact angle formed between the edge of a water drop placed on the surface of the insulator and the surface of a material.
2. Surface tension method: the method indirectly reflects the hydrophobicity state of the line insulator through the surface tension of the given mixed liquid.
3. Water spraying classification method: the method comprises the steps of spraying water mist on the surface of the insulator, observing the wetting state of water on the surface of the insulator, and contrasting grading criteria and a reference image to obtain the state of hydrophobicity of the line insulator.
At present, in domestic electric power companies, power plants and other insulator application environments, when the hydrophobicity of the insulator is detected, a water spraying classification method is widely applied. Although the detection principle is mature, the insulator is installed in a power system, so that the field detection has the problems of inconvenient operation, high danger and the like.
