63kv 66kv 69kv High Voltage Power Transformer Position in power system

In power systems, 66kV high voltage power transformers are commonly found in secondary substations, also known as intermediate substations. These transformers receive high-voltage electricity from primary substations and step it down to a lower voltage, making it suitable for the distribution network. This process ensures the efficient and reliable delivery of power to end users.

High Voltage Power Transformer Protection Devices: Ensuring Safety and Reliability

Pressure Relief Valve
The pressure relief valve is a critical safety device in high voltage power transformers, designed to release internal pressure when it becomes too high, preventing potential transformer explosion.

Principle: The valve operates as a safety mechanism. When the internal pressure exceeds the set limit, the valve automatically opens to discharge excess gas or oil vapor. This prevents further pressure buildup, ensuring both the safety of the transformer and the surrounding environment.

Usage: Typically installed on the top or side of the transformer tank, the pressure relief valve requires regular inspection and maintenance to ensure its responsiveness and reliability.
Gas Relay
The gas relay is designed to monitor gas levels within the transformer oil, quickly detecting internal faults that could compromise the transformer’s performance.

Principle: Installed on the pipeline between the transformer tank and the cooling system, the gas relay contains a float and electrical contacts. When a fault such as a short circuit or overload occurs, gas is generated and rises to the top of the tank, pushing the float down. This triggers the electrical contacts, sending an alarm or cutting off the power supply to prevent further damage.

Solicitud: Commonly used in oil-immersed high voltage power transformers, the gas relay ensures early detection of faults. Regular inspections and maintenance are necessary to maintain its accuracy and reliability.
Temperature Monitor
The temperature monitor is essential for real-time monitoring of the transformer’s temperature, helping to prevent overheating and ensure safe operation.

Principle: Consisting of a temperature sensor and display, this device is installed on the transformer windings and oil tank surface. It continuously measures the transformer’s temperature and transmits the data to a display or control system. If the temperature exceeds the preset safety threshold, the system will trigger an alarm or activate cooling measures, such as starting a cooling fan or oil pump, to prevent overheating.

Solicitud: Widely used in high voltage power transformers, the temperature monitor is essential for maintaining safe operating conditions. Regular calibration and maintenance ensure its accuracy and quick response to temperature changes.
