Why Monitor Transformer Windings
Pagsubaybay sa temperatura ng winding ng transformer is a critical component for safe operation of modern power systems. As the core equipment of power systems, abnormal temperature changes in transformer windings directly affect equipment safety and grid stability.
Paikot-ikot na sobrang init is the most common cause of transformer failures, accounting para sa higit 60% of total transformer faults. kailan paikot-ikot na temperatura exceeds rated values, it accelerates insulation material aging, reduces dielectric strength, and ultimately leads to insulation breakdown and equipment damage. Statistics show that for every 8°C increase in insulation temperature, its service life is halved.
Pagpapatupad paikot-ikot na pagsubaybay sa temperatura has the following important significance: preventing equipment overheating damage, pagpapahaba ng buhay ng serbisyo ng kagamitan, improving power supply reliability, pagbabawas ng mga gastos sa pagpapanatili, pagpapagana predictive maintenance, ensuring personnel safety, at pagbabawas ng mga pagkalugi sa ekonomiya. Through continuous monitoring of winding temperature changes, operation and maintenance personnel can detect abnormal conditions in time and take appropriate measures to prevent major accidents.
