Composite Insulator Live Voltage Detection Device

No Chinese content provided..Chapter Usage

The excellent hydrophobicity and unique hydrophobic migration properties of composite insulators effectively prevent flashover and reduce accidents. Hydrophobicity refers to the insulator surface's resistance to moisture, with adsorbed water existing as discontinuous, isolated droplets, rather than forming a continuous film, thereby limiting surface leakage current and increasing the flashover voltage. Hydrophobic migration property means that when the hydrophobic material surface becomes contaminated, it can transfer its hydrophobic properties to the soiling, making the soiled surface also hydrophobic. Practical evidence shows that during operation, the hydrophobicity of composite insulators can decline or even be lost due to factors such as contamination, humidity, discharge, and low temperatures, directly affecting... The anti-fouling performance of power transformers and transmission equipment can even threaten the safe operation of the system. Therefore, the hydrophobic property of the composite insulators in operation needs to be addressed. Routine sex testing is highly necessary.

ED0409The Composite Insulator Voltage Detector boasts a simple structure and user-friendly operation, enabling quick and accurate assessment of the hydrophobic condition of insulators. Main application fields include power companies, composite insulator manufacturing plants, line maintenance, relevant departments and units responsible for maintaining high-voltage lines in the power industry, power plants, schools, research institutions, and other related organizations.

2.1 Basic working methods

（1Adopting the spray mist grading method (i.e.)HC Grading System.

（2Adopting a combined approach of working both on the tower and on the ground.

（3Employees ascend the tower to inspect the operating composite insulator near the grounding side.1～3 A waterproof test was conducted on an umbrella skirt: First, the skirt was subjected to a quantitative spray of water mist, followed by digital photography of the composite insulator after the spray.

（4Staff returned to ground level, transmitting digital images captured from above.USB Data transmission lines are input into the computer, where they are analyzed using hydrophobicity analysis software to evaluate the hydrophobic status of composite insulators.

2.2 Hydrophobic Grade Classification Method

The spray water grading method classifies the hydrophobicity of the surface of composite insulators. HC1-HC7 Seven levels.HC1 The state corresponding to hydrophobicity.HC7 The device employs two methods as described to grade the hydrophobic state of the composite insulator surface.
