Introduction

The Middle East is known for its extremely hot climate. The perennial high temperatures, intense sunlight, and dusty environment pose significant challenges to the stable operation of power transformers. As the core equipment of the power system, frequent failures of power transformers can not only affect the local power supply but also have a serious negative impact on industrial production and residents’ lives. Therefore, it is urgent to find effective solutions to address the failure problems of power transformers in the hot regions of the Middle East.

Problems Faced by Power Transformers in the Hot Regions of the Middle East

Accelerated Insulation Aging Caused by High Temperatures

In the hot regions of the Middle East, summer temperatures often exceed 40°C, and in some extreme cases, they can reach over 50°C. High temperatures can degrade the performance of the transformer’s insulation materials and accelerate the aging process. Insulation aging leads to a decrease in insulation resistance, increasing the possibility of partial discharge and potentially causing serious faults such as insulation breakdown.

Impact on Equipment Performance due to Dust Invasion

The dusty environment in this region allows a large number of dust particles to easily enter the transformer. Dust can accumulate on the radiator fins, windings, and other parts of the transformer, affecting the heat dissipation effect and causing the transformer temperature to rise further. Additionally, conductive substances in the dust can damage the insulation structure and trigger electrical faults.

Increased Equipment Burden due to Large Load Fluctuations

The electricity demand in the industrial and commercial activities in the Middle East varies significantly at different times, resulting in obvious load fluctuations of power transformers. Frequent load changes subject the transformer windings to greater mechanical and thermal stresses, accelerating the wear and aging of the equipment and increasing the probability of failures.

Effective Solutions

Strengthen Heat Dissipation Management

• Use High – efficiency Heat Dissipation Equipment: Install high – efficiency radiators and cooling fans to improve the heat dissipation efficiency of the transformer. For example, adopting forced air – cooling or water – cooling systems can promptly dissipate the heat generated by the transformer and reduce the equipment temperature.
• Optimize the Heat Dissipation Structure Design: Optimize the design of the transformer’s radiator fins to increase the heat dissipation area and enhance the heat dissipation effect. At the same time, reasonably plan the installation location of the transformer to ensure smooth air circulation around it.

Implement Dust – proof Protection

• Install Dust – proof Filters: Install high – efficiency dust – proof filters at the air inlets and outlets of the transformer to prevent dust particles from entering the equipment. Regularly clean and replace the filters to ensure their filtering effect.
• Adopt a Sealed Structure: Design the transformer with a sealed structure to reduce the possibility of dust invasion. Additionally, strengthen the detection of the transformer’s sealing performance and promptly find and repair any sealing leaks.

Intelligent Monitoring and Maintenance

• Install an Intelligent Monitoring System: Utilize advanced sensors and monitoring technologies to continuously monitor the operating status of the transformer, such as temperature, humidity, current, and voltage. Once an abnormal situation is detected, an alarm is immediately issued to enable maintenance personnel to take action.
• Develop a Scientific Maintenance Plan: Based on the operating conditions and monitoring data of the transformer, formulate a scientific and reasonable maintenance plan. Regularly inspect, clean, maintain, and test the transformer to promptly identify and address potential fault hazards.

Case Study

Take a large industrial park in Saudi Arabia as an example. In the past, due to the hot and dusty environment, the power transformers in the park frequently malfunctioned, affecting the normal production of enterprises in the park. Later, the park management department adopted the above solutions, strengthened the heat dissipation management and dust – proof protection of the transformers, and installed an intelligent monitoring system. After a period of operation, the failure rate of the transformers decreased significantly, and the stability of the power supply was effectively improved.

Conclusion

In the hot regions of the Middle East, the frequent failures of power transformers are an urgent problem to be solved. By strengthening heat dissipation management, implementing dust – proof protection, and carrying out intelligent monitoring and maintenance, the failure rate of transformers can be effectively reduced, and the reliability and stability of the power supply can be improved. For local power enterprises and relevant departments, attaching importance to the implementation of these solutions will contribute to ensuring the safe operation of the power system and promoting sustainable economic development.
