<\/p>\nExcessive core loss of electrical steel is a common quality problem for transformer cores. Unqualified iron loss parameters will trigger a series of adverse effects on transformer operation and service life.<\/p>\n
First, excessive core loss increases transformer no-load power consumption. No-load loss exists continuously after equipment power-on. High iron loss causes long-term invalid energy consumption. It raises grid operation costs and fails energy-saving policy standards.<\/p>\n
Second, it leads to abnormal temperature rise of transformer cores. Magnetic loss converts into heat energy during operation. Excessive loss accumulates massive heat inside the core. Overheating affects surrounding insulating materials. It accelerates insulation aging and reduces equipment safety margin.<\/p>\n
Third, it increases transformer operating noise and vibration. High-loss electrical steel has unbalanced magnetic domain movement. It enhances magnetostriction vibration amplitude. The whole transformer produces larger noise during operation. It worsens on-site operation environment.<\/p>\n
<\/p>\n
Fourth, it causes unstable transformer output performance. Excessive iron loss leads to fluctuating core magnetic flux. It makes transformer voltage output unbalanced. This fluctuation affects power supply quality of terminal electrical equipment.<\/p>\n
Fifth, it shortens the overall service life of transformers. Long-term overheating and vibration accelerate aging of steel cores and insulation. Equipment failure risk rises significantly. The service cycle of transformers is shortened obviously.<\/p>\n
Sixth, it causes equipment acceptance failure and operational risks. Transformers with unqualified iron loss cannot pass factory detection. Put-into-operation equipment with excessive loss faces overload hidden dangers. It may trigger local overheating and even short-circuit faults.<\/p>\n
In conclusion, excessive electrical steel core loss harms transformer energy efficiency, safety and stability. Strict incoming inspection of steel iron loss is essential to guarantee qualified transformer operation.<\/p>","protected":false},"excerpt":{"rendered":"
