Structure

 

High temperature resistant coil
The component has a well - designed structure. Its advanced materials enable it to resist temperatures up to 150 °C. The high - quality insulation not only offers good electrical insulation but also makes it less likely to age. This, along with its structure, greatly improves the machine's life and ensures reliable operation in tough conditions.

Core
The core conducts magnetic flux for energy transfer between windings. An AC in the primary creates a magnetic field guided by the core to the secondary, inducing an EMF. It offers benefits: high - permeability materials reduce excitation current and size; low - loss design cuts energy use; good mechanical strength ensures reliable operation; low noise suits quiet areas; excellent thermal stability allows wide - temperature operation.

Resin artcract
Resin in cast resin dry - type transformers serves multiple functions. It provides insulation, mechanically fixes components, keeps out moisture, and aids in heat dissipation. Its advantages include good electrical performance, excellent mechanical properties, chemical corrosion resistance, good processability, and environmental friendliness, all of which contribute to the reliable operation and long - term performance of the transformer.

Cross flow cooling fan
The cross - flow cooling fan is installed adjacent to the windings. Its blades are designed to direct air across a wide heat - dissipation area. As the fan operates, it accelerates air movement, quickly removing heat. This reduces heat increase, preventing component overheating and enhancing the transformer's reliability for stable long - term operation.

The control cabinet
Function:Monitors the dry - type transformer's operation, like temperature and voltage. Can issue alarms and control cooling systems when needed, ensuring safe and stable operation.
Structure:Enclosed in a white cabinet. Inside, there are various control and protection devices, with a small window for partial status observation.
Inside the control cabinet:
1.Relays are used to control and isolate circuits, protecting the transformer from overloads and short - circuits.
2.Meters like voltmeters and ammeters display real - time voltage and current values, helping operators monitor the transformer's operation.
3.Temperature controllers monitor the transformer's temperature and can activate cooling fans when it exceeds a set limit.
4.Circuit breakers can cut off the power supply in case of emergencies to ensure safety.
5.PLC (Programmable Logic Controller) or other control units manage and coordinate the overall operation based on input signals.

Performance Parameters
(The value can be customized according to customer's local demand!)
Note: The voltage can be designed up to 4000KVA,voltage up to 36KV,with different technical request.
