2.Remote Online Laser-Based Defect Elimination System for Disconnector Contacts
Laser suna da high directionality and brightness, kuma suna da amfani don koyar da energy into a confined space. Laser cleaning fundamentally involves the interaction between laser radiation and contaminants, producing chemical and physical effects.

Research shows that surface contaminants adhere via capillary forces, electrostatic attraction, covalent bonding, and van der Waals forces—the latter three being particularly difficult to overcome. Laser cleaning disrupts these binding forces without damaging the underlying substrate.

Three primary laser cleaning mechanisms exist:
(1) Fragmentation and spallation: Microscopic contaminant particles absorb laser energy, expand rapidly, overcome surface adhesion forces, and fracture off the surface. The ultrashort laser pulse generates explosive shockwaves that accelerate particle detachment.
(2) Evaporation: Due to differing chemical compositions between the substrate and contaminants, their laser absorption rates vary. With appropriate laser type and pulse width selection, ~95% of laser energy reflects off the substrate, protecting it. Contaminants absorb ~90% of the energy, causing instantaneous temperature rise and vaporization, which removes them without substrate damage.
(3) Vibrational ejection: Short-pulse lasers induce ultrasonic vibrations through rapid thermal expansion. The resulting shockwaves fragment and eject particles.

The remote online defect-elimination system concentrates high energy within a precise spatial and temporal window. At the focal point, ionization causes micro-explosions that instantly strip away contaminants. The highly directional laser beam can be shaped into adjustable, non-uniform spot sizes. Laser energy intensity is precisely controlled to ensure instantaneous separation of contaminants from the substrate without damage.

3.Common Defects in High-Voltage Disconnectors During Operation
Defects often arise during operation—for example, dust accumulation due to poor contact, or formation of compound films on contact surfaces, increasing contact resistance. Analysis reveals that poor design, substandard components, and improper installation or adjustment all contribute to defects.

3.1 Component Corrosion
Prolonged exposure to rain, wind, and humidity causes corrosion of disconnector components. Some parts use galvanized coatings, but electrochemical reactions during operation can lead to severe rusting. Poor manufacturing processes further compromise quality and performance, accelerating corrosion. Severe rusting reduces mechanical transmission speed and may cause operational failure.

3.2 Incomplete Opening/Closing and Overheating
Improper opening or closing operations often result in defects. If contacts do not fully engage while the circuit remains energized, resistive heating occurs, potentially leading to burnout or safety incidents—impacting economic performance and power reliability.

Severe overheating at contact points (due to persistent current flow even when damaged) increases contact resistance, creating a vicious cycle: higher resistance → higher temperature → further resistance increase → contact damage.

3.3 Poor Sealing of Operating Mechanism Leading to Contact Damage
Most high-voltage disconnectors operate outdoors and are vulnerable to environmental factors. The operating mechanism serves as the power source; if corroded, it impairs functionality.
