Transformer Specialized Oven
Category：Tunnel Oven Production Line
Introduction
The Transformer Specialized Oven is an industrial-grade constant temperature heating equipment specially designed for insulation drying and curing treatment of power transformers, current transformers, reactors, and other electrical equipment during manufacturing and maintenance processes.
Applications
Insulation Drying:
Used to remove moisture from transformer coils and insulation materials.
Varnish Impregnation Curing:
Used for heating, drying, and curing transformer coils after insulation varnish impregnation.
Thermal Assembly Process:
Used for preheating iron cores or specific components during thermal assembly operations.
Technical Parameters
| Parameter | Specification |
|---|---|
| Overall Dimensions (W×D×H) | W1560 × D1580 × H2200 mm |
| Inner Chamber Dimensions (W×D×H) | W1300 × D1400 × H1800 mm |
| Temperature Range | Room temperature to 250℃ (Adjustable) |
| Power | 18 kW |
| Power Supply | 380V, Three-phase five-wire system |
| Temperature Uniformity | ±3℃ (No-load test) |
| Air Circulation Method | Two-side circulating high-volume forced horizontal air circulation |
| Heating Method | Imported U-shaped stainless steel heating tubes with heat dissipation fins |
| Explosion-proof Device | An explosion-proof pressure relief door is installed at the rear of the equipment. When the internal pressure reaches a certain level, the door automatically opens and the equipment power supply is cut off. |
| Thermal Insulation | 100 mm thick high-temperature resistant aluminum silicate fiber cotton insulation; high-temperature resistant silicone sealing strips are added around the door edges |
| External Material | The outer shell is made of 1.2 mm cold-rolled steel sheet with high-temperature powder coating treatment (not ordinary spray painting) |
| Inner Chamber Material | 1.5 mm thick galvanized steel sheet |
| Control Protection Functions | PID self-tuning, automatic constant temperature control, automatic timing, over-temperature power-off alarm after reaching the set temperature, over-temperature power cut-off, emergency stop switch, leakage protection circuit breaker, motor overload protection, and other safety functions |
| Temperature Control System | Four units share one electrical control cabinet. Two units connected in parallel are equipped with one paper chart recorder (two recorders in total). |
Features
Precise Temperature Control:
Adopts a microcomputer-based intelligent PID control algorithm to achieve accurate temperature regulation.
High Temperature Uniformity:
The unique air duct design ensures extremely small temperature differences throughout the chamber.
Safety and Explosion Protection:
Equipped with over-temperature alarm, moisture exhaust system, and explosion-proof pressure relief door.
Strong Load Capacity:
The bottom rail trolley design facilitates convenient loading and unloading of heavy transformers.
