What are the insulation faults of outdoor vacuum reclosers and their solutions?正方型 单相.png

Insulation Faults:

Insulator Flashover:

  • Clean Insulators: For insulators that experience flashover due to surface contamination, regular cleaning is necessary. Specialized insulator cleaning tools, such as insulator cleaning brushes or high-pressure water guns, can be used. After cleaning, anti-flashover coatings can be sprayed on the insulator surfaces to enhance their contamination resistance.

  • Replace Insulators: If insulators show a decrease in insulation strength due to lightning strikes or other reasons, and exhibit obvious cracks or damage, they should be replaced promptly. When replacing insulators, choose ones that meet the voltage and mechanical strength requirements of the equipment.

Insulation Aging:

  • Test Insulation Performance: Use insulation resistance testers, dielectric loss testers, and other equipment to regularly test the insulation performance of insulating materials. When a decline in insulation performance is detected, analyze the causes of aging.

  • Replace Insulation Components: If insulation aging is severe, such as when partial discharge phenomena are observed, aged insulation components (e.g., insulating bushings, insulating supports) should be replaced promptly. Additionally, improve the operating environment of the equipment, such as by enhancing ventilation and reducing humidity, to slow down the aging process of the insulation.

Development of an Outdoor Integrated Low - Voltage Current Transformer
Development of an Outdoor Integrated Low - Voltage Current Transformer
In power grid construction, line losses reflect planning, design, and operation management. They’re key for evaluating power systems. For refined low - voltage transformer area line loss management, accurate line loss counting is critical. So, solidifying basic data, ensuring data accuracy, and proper original data collection matter for analysis. We must also optimize factors affecting collection accuracy, make preventive measures, and boost refined line loss management.1 Current Status of

Ratio Trial Verification Method for Current Transformers
Fellow electric power calibration workers, you must have encountered this situation: The nameplate of an outdoor current transformer has been tormented by wind, sun, rain, and freezing, to the point where the transformation ratio is indistinguishable! Don't panic, we have a solution - use a current transformer calibrator and through the “transformation ratio trial calibration method”, we can figure out the actual transformation ratio and errors clearly. Here, taking the SHGQ - DC typ
