How to guarantee the airport transformer

As an important hub of modern transportation, the airport undertakes the tasks of a large number of passenger transportation, cargo transfer and flight take-off and landing. Its normal operation depends on stable and efficient power supply, and transformer, as the core equipment in the power system, plays a vital role in the airport power supply system. This paper will discuss how to ensure the safety and stable operation of the airport transformer from the aspects of transformer function, configuration requirements and safeguard measures.

First of all, the main function of the airport transformer is to convert the high-voltage electricity in the power transmission system into low-voltage electricity suitable for the internal equipment of the airport, and provide stable power support for the terminal lighting, security inspection system, runway lighting, tower communication, monitoring system and ground equipment. The airport requires high continuity and stability of power supply. Any interruption or fluctuation of power supply may lead to flight delay, equipment failure and even endanger flight safety.

In order to meet the airport's demand for high reliability, airport transformers are usually designed and installed with redundant configuration and multiple safeguard measures. For example, airports are usually equipped with main transformers and standby transformers, and seamless switching is realized through automatic switching devices to ensure that when one transformer fails or is overhauled, the other transformer can be put into use immediately. In addition, some large airports will also set up emergency diesel generator systems as the third guarantee to ensure that key equipment can still operate normally under extreme conditions.

In terms of daily operation and maintenance, the airport power department will conduct regular inspections, preventive tests and condition monitoring of transformers, and find potential faults in time by means of infrared thermal imaging and oil chromatography analysis. At the same time, establish a perfect power monitoring system to realize real-time monitoring and remote control of transformer operation state and improve emergency response capability.

In addition, the site selection and construction of airport substation should also consider safety factors such as lightning protection, waterproof and fire prevention to ensure that the transformer is in a safe and stable operating environment. For example, in rainy areas in the south, transformer rooms need to have good drainage facilities; In areas with frequent lightning, it is necessary to install lightning arrester and other protective equipment.

To sum up, the airport transformer not only undertakes the core task of power conversion, but also is the key facility to ensure the all-weather operation of the airport. Through scientific design, strict operation and maintenance management and multiple guarantee mechanisms, the airport transformer effectively supports the normal development of various airport businesses and provides a solid guarantee for the safe take-off and landing of flights and the smooth travel of passengers. In the future, with the development of smart grid and digital operation and maintenance technology, the operation efficiency and reliability of airport transformers will be further improved, providing stronger support for the construction of smart airports.
