Importance in High Voltage Transmission and Distribution

Why this 110kV to 550kV Oil Immersed High Voltage Power Transformer is important is to mention the efficiency in terms of power transmission.When the voltage rises to 110kV, the loss is minimized when the power is transmitted over a long distance, the current in the conductor is reduced, the resistance loss is reduced, and the efficiency of the whole transmission process is very high.And it can also maintain the voltage in a stable range, if you are worried about voltage fluctuations damage to equipment, can choose our this product to provide protection.

The standard for most of the world's national grids is 110kV, and our transformers meet this standard, are more adaptable, and can be customized to specific voltage requirements and expanded to meet growing demand.Compliant with international standards such as IEC 60076, ANSI/IEEE C57, EN 60076, it is capable of handling high power.

Protection Systems

The protection system of 110kV to 550kV Oil Immersed High Voltage Power Transformer is not a single one, but covers many aspects, from oil temperature monitoring, oil level monitoring, pressure protection, gas monitoring and overcurrent protection.

The oil temperature of transformer oil needs to be monitored. The change of high temperature is a prompt for abnormality and failure. When the system alarm is triggered, it prompts you to take corresponding measures.In addition, regarding the transformer mailbox, the oil level also needs to be noted, low or high is not a good phenomenon, you can use the oil level monitoring system to judge the problem and deal with it.

This aspect of pressure protection is also the monitoring of oil pressure, oil pressure too high will cause equipment leakage or damage.The gas monitoring system is responsible for detecting the content of combustible gases inside.Finally, in order to protect the transformer from overload or short circuit, the overcurrent protection system is designed to trigger the protection action when the current exceeds the set threshold.
