6. What Are the Common Hotspot Faults in Transformers?

6.1 Winding Hotspot Overheating

Winding hotspot overheating is the most common thermal fault in dry type transformers. Causes include excessive load current, poor cooling system performance, تهویه مسدود شده, or localized short circuits between turns. Without timely detection and intervention through سیستم های نظارت بر دما, sustained overheating causes rapid insulation degradation, potentially leading to catastrophic failure. سنسورهای دما PT100 positioned at winding hotspots provide early warning before critical damage occurs.

6.2 Unbalanced Phase Loading

Three-phase transformers often experience unbalanced loading where one phase carries significantly higher current than others. This creates a thermal imbalance where one winding operates at higher temperature while others remain cooler. Single-point temperature measurement can miss this condition. The IB-S201 series monitors all three windings simultaneously, displaying the highest temperature to ensure comprehensive protection regardless of load distribution.

6.3 خرابی سیستم خنک کننده

Cooling fan failures represent serious risks for transformers relying on forced air cooling. Fan motor burnout, bearing seizure, or control circuit faults can cause rapid temperature escalation. این transformer temperature controller’s fan exercise function prevents mechanical failures through periodic operation. علاوه بر این, the system monitors temperature trends, triggering alarms if temperatures rise abnormally despite fan operation, indicating potential cooling system malfunctions.

6.4 اثرات دمای محیط

Extreme ambient temperatures significantly impact transformer thermal performance. High ambient temperatures reduce cooling efficiency and narrow the margin between operating temperature and maximum rated temperature. The IB-S201G model’s ambient temperature monitoring enables calculation of actual temperature rise independent of environmental conditions, providing more accurate assessment of transformer thermal stress. This is particularly valuable in regions experiencing extreme seasonal temperature variations.

6.5 Core Hotspots and Magnetic Circuit Issues

Although less common than winding faults, core overheating can occur due to excessive magnetic flux density, core lamination short circuits, یا عیوب ساخت. Core hotspots are difficult to detect without dedicated sensors. The IB-S201I model’s core temperature monitoring capability enables early detection of magnetic circuit problems before they cause extensive damage. This is especially important for custom-designed transformers or units operating near saturation limits.
