6. What Are the Common Hotspot Faults in Transformers?

6.1 Przegrzanie hotspotu uzwojenia

Przegrzanie gorącego punktu uzwojenia jest najczęstszą usterką termiczną w transformatorach typu suchego. Przyczyny obejmują nadmierny prąd obciążenia, słaba wydajność układu chłodzenia, zablokowana wentylacja, lub zlokalizowane zwarcia pomiędzy zwojami. Bez szybkiego wykrywania i interwencji systemy monitorowania temperatury, długotrwałe przegrzanie powoduje szybką degradację izolacji, potencjalnie prowadząc do katastrofalnej awarii. Czujniki temperatury PT100 umieszczone w krętych, gorących punktach, zapewniają wczesne ostrzeganie przed wystąpieniem krytycznych uszkodzeń.

6.2 Niezrównoważone obciążenie fazowe

Transformatory trójfazowe często doświadczają niezrównoważonego obciążenia, w którym jedna faza przepływa znacznie większy prąd niż inne. 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 Awarie układu chłodzenia

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. Ten transformer temperature controller’s fan exercise function prevents mechanical failures through periodic operation. Dodatkowo, the system monitors temperature trends, triggering alarms if temperatures rise abnormally despite fan operation, indicating potential cooling system malfunctions.

6.4 Wpływ temperatury otoczenia

Extreme ambient temperatures significantly impact transformer thermal performance.
