Epoxy Resin Dry Type Transformer
Epoxy resin dry type transformer is a high safety power equipment that uses epoxy resin as the insulation medium and vacuum casting technology to encapsulate the coil as a whole. Epoxy resin is flame-retardant and does not produce toxic gases even when burned. Additionally, it has strong environmental adaptability and can operate stably in a 100% humidity environment. It is designed for high-rise buildings, data centers, hospitals, subways, airports, commercial centers, chemical plants and other places with high fire safety requirements and limited installation space, meeting the high reliability power supply needs in complex environments.

XIV. FAQ
Q1. What could be causing an abnormally high winding temperature? How should it be handled?
Causes: Usually caused by cooling system malfunction (e.g., fan failure), prolonged overload operation, severe dust accumulation on the winding surface, or internal faults (e.g., inter-turn short circuits).
Handling: First, clean the winding and inspect/replace the faulty fan; if the temperature remains high after reducing the load, the machine must be stopped and the insulation and DC resistance tested to rule out internal faults.
Q2. What factors cause a decrease in insulation resistance? How should it be resolved?
Causes: The main causes are winding dampness, surface dirt and dust accumulation, aging insulation materials, or excessive humidity in the operating environment.
Handling: The winding should be cleaned and dried (e.g., hot air drying), and measures should be taken to reduce ambient humidity (recommended ≤85%) to fundamentally prevent moisture absorption.
Q3. What faults might be indicated by abnormal sounds heard during operation?
Causes and Handling:
"Crackling" discharge sound: This may indicate insulation breakdown; the machine must be stopped immediately for inspection and replacement of damaged insulation.
A sharp "buzzing" sound: This is often caused by overload or overvoltage, requiring load reduction or checking the mains voltage.
A continuous friction sound: This may originate from loose core clamps or worn fan bearings, requiring tightening or replacement as needed.
