Pressure Relief Valve

The pressure relief valve of an oil-immersed transformer has various characteristics that ensure its effectiveness and reliability in protecting the safe operation of the transformer. Here are the main features:

Main Features

1. Automatic Pressure Relief:

Automatic Opening: When the internal pressure of the transformer exceeds the preset safety value, the valve automatically opens to release the excess pressure, preventing the transformer casing from cracking or exploding.

Automatic Closing: Once the pressure drops to a safe range, the valve automatically closes, restoring the internal seal of the transformer.

2. High Sensitivity and Reliability:

Accurate Response: It can quickly respond when the pressure reaches the set value, ensuring timely pressure release.

Stable Performance: The design and manufacturing process ensure stable performance under various conditions, with minimal interference from external factors.

3. Durability:

High-Quality Materials: Made of corrosion-resistant and high-temperature-resistant materials, ensuring long-term use in harsh environments.

Wear Resistance: Key components have good wear resistance, extending the valve’s service life.

4. Simple Structure, Easy Maintenance:

Simple Design: The simple structure makes it easy to install, inspect, and maintain.

Easy to Clean: Designed to prevent dust and contamination, making it easy to clean.

5. Safety:

Explosion-Proof Design: Equipped with explosion-proof features to ensure reliable operation under extreme conditions, preventing transformer hazards due to excessive internal pressure.

High-Reliability Sealing: Ensures sealing performance when the valve is closed, preventing oil and gas leaks.

6.Customizable Options:

Various Specifications: Offers multiple specifications and models based on different transformer capacities and operating environments.

Adjustable Set Value: Some valves allow adjustment of the opening pressure value to suit different working conditions.

Application Examples

Power Transformers: Used in large and medium-sized oil-immersed power transformers in power systems to ensure safety under various operating conditions.

Industrial Transformers: Suitable for transformers used in industrial fields to prevent overpressure problems caused by complex working conditions.

Transformers in Special Environments: Such as offshore platforms, mines, etc., ensuring reliable operation in special environments.

Maintenance and Management

Regular Inspection: Regularly inspect the valve's status and performance to ensure its sensitivity and reliability.

Cleaning and Lubrication: Periodically clean and lubricate the valve as needed based on the operating environment to prevent sticking.

Testing and Calibration: Conduct regular testing and calibration to ensure the valve opens and closes properly at the set pressure, maintaining its protective function.

Summary

The pressure relief valve of an oil-immersed transformer is an essential protective device for the safe operation of the transformer, featuring automatic pressure relief, high sensitivity, durability, and safety. Through proper selection, installation, and maintenance, it can effectively prevent safety incidents caused by excessive internal pressure, ensuring long-term stable operation of the transformer.
