Improvement measures for preventing burnout of drop-out fuses
Date: | Read: 23
Install online monitoring
Install wireless temperature sensors (accuracy ± 1 ℃) and Hall current probes on the drop out fuse body to monitor in real-time:
Contact temperature rise rate (>3 ℃/min alarm)
Current harmonic distortion rate (THD>8% warning)
Environmental adaptability renovation
316L stainless steel fasteners are used in coastal areas, which undergo salt spray testing for up to 480 hours without corrosion.
Install silicone rubber climbing skirts in heavily polluted areas, with an effective climbing distance greater than 31mm/kV
Protection coordination optimization
Configure inverse time electronic protection module, set:
Quick break protection: 8Ie/0.1s
Overload protection: 1.3Ie/300s
Temperature protection: Trip at 90 ℃
