In oil-immersed transformer production, processes such as core heating, electromagnetic coil pre-drying, coil drip-drying, and epoxy resin curing are critical, directly impacting transformer quality. Consequently, stringent requirements exist for temperature uniformity and the reliability of automatic control systems in transformer curing ovens. Transformer curing ovens feature excellent temperature uniformity, diverse and flexible air delivery methods, comprehensive and reliable automatic control systems, and an aesthetically pleasing surface. They have gained widespread adoption among domestic oil-immersed transformer manufacturers.
Key Performance Features of Transformer Curing Ovens:
Intelligent programmable temperature controllers are employed, featuring self-tuning PID parameters, intermediate relay power adjustment, and contactless switch continuous regulation. The entire drying process operates automatically, meeting all curing curve requirements with simple operation and reliable performance. The control system for global electrical equipment has been optimized, enhancing the stability of the oven's motor control components.
Intermittent automatic venting functionality is available within the processing temperature range (optional based on customer requirements). Selectable monitoring options include paper-feed recorders, print recorders, or paperless recorders for full-process surveillance and analysis of drying/curing outcomes.
Scientific hot-air circulation methods tailored to different item layouts (e.g., top heating with vertical exhaust, bottom heating with horizontal exhaust, side heating with vertical exhaust) ensure uniform chamber temperatures and superior drying/curing results.
A dedicated overheat alarm device is provided. Upon detecting abnormal temperatures, it shuts off the heating power supply and triggers audible and visual alarms. A low-voltage lighting system can be installed, with a viewing window on the door for real-time observation of workpiece curing progress. Sealed heating tubes are used for heating, offering advantages of oxidation resistance, stable performance, and extended service life.
Basic Features of Transformer Curing Ovens:
1. Hot air circulation system ensures uniform temperature distribution within the chamber.
2. The front-mounted ventilation system with high airflow ensures combustible gas concentrations within the chamber remain within safe limits.
3. Surface-sealed heating tubes with low operating temperatures offer extended service life.
4. Equipped with track-mounted manual carts for loading workpieces or test specimens, enhancing operational efficiency.
5. Thickened aluminosilicate insulation wool provides excellent thermal retention, minimizing energy loss.
6. Pressure relief door design reduces potential accident damage.
7. Independent control console allows for local operation or centralized management from a control room.
8. Intelligent digital programmable temperature controller with PID self-tuning automatically adjusts parameters based on process requirements.
9. Over-temperature protection triggers audible and visual alarms while cutting off heating power to safeguard equipment and workpieces.
10. Manufacturer specializing in custom-built transformer and motor curing ovens.
