محول الإشعال De Dietrich 7624619

The De Dietrich 7624619 ignition transformer, listed under catalogue article 336.823.006, is a component that belongs to the group of ignition transformers used in burners and industrial heating systems. Parts of this type step up the mains voltage to a level sufficient to generate a spark across the ignition electrode gap. The transformer is energised only during the ignition phase, under command from the burner control (control box or flame safeguard). It plays a critical role in the start-up sequence: after pre-purge and once the burner control signals ignition, the transformer produces the spark that ignites the fuel-air mixture admitted by the gas valve or oil pump. When selecting a replacement ignition transformer, the key parameters to match are the secondary voltage and current, primary voltage (usually 230 V, but 110 V and 24 V variants exist), and duty cycle. The mounting arrangement, terminal type, and connector pattern for the high-voltage ignition cable must also be compatible with the existing wiring and electrode assembly. The high-voltage cable on such transformers is typically silicone-insulated to withstand heat and electrical stress. A hardened, cracked, or oil-soaked cable can leak the spark to earth, causing a weak or missing spark that might be mistaken for a failed transformer. When replacing a transformer, inspect the cable and the electrode gap as well. No further specifications for this particular De Dietrich article are provided beyond its catalogue codes and brand.
