Temperature Control System for Transformers

Shandong Zhifeng Transformer Co., Ltd. offers a cutting-edge temperature control system for transformers. The system comprises a temperature controller and a PTC temperature measuring element strategically placed at the top end of the low-voltage winding, the hottest spot in the product. This setup enables precise temperature measurement and control of the transformer.

In case of overheating due to overload or faults, the temperature controller promptly sends an alarm signal, automatically tripping the temperature when it exceeds the safe threshold. For transformers utilizing forced air cooling, the temperature controller regulates the cooling fan based on the winding temperature.

The temperature display system provides real-time monitoring of the winding's hot spot temperature during transformer operation and seamlessly integrates with the temperature control system.

Both the temperature control and display systems can be conveniently installed at a distance from the transformer's main body. The lead wire length for the temperature measuring element is as follows:

• Temperature control: <20m
• Temperature display: <10m (two-wire system) or <100m (two-wire system with compensating wire)

Trust Shandong Zhifeng Transformer Co., Ltd. for reliable and efficient temperature control solutions for your transformers.

Transformer Core
1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.
2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
3. Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.

Product Description:

Shandong Zhifeng Transformer Co., Ltd. offers transformers with shells made of stainless steel or aluminum alloy. The protection grade can reach IP20 and IP23. IP20 housing prevents solid foreign objects with a diameter of more than 12mm from entering, ensuring transformer safety. IP23 housing is suitable for outdoor operations, preventing vertical drops of less than 60° of flow. Additionally, IP23 housing helps in cooling the transformer, with a decrease in small capacity by about 5% and high capacity by about 10%.
