Pad-Mount Transformer Components System

​

  Key Components & Features

1.Pressure Vacuum Gauge​

Monitors internal pressure and vacuum status in real-time, preventing abnormal pressure changes and ensuring equipment safety.

2. Pressure Relief Valve​

Automatically releases over-pressure, responds rapidly to internal faults, prevents tank rupture, and enhances operational reliability.

3. Oil Level Indicator

Visually displays insulating oil level for easy daily inspection and maintenance, preventing equipment faults due to abnormal oil levels.

4. Thermometer

Continuously monitors transformer operating temperature, provides early warning against overheating risks, and extends equipment service life.

5. Oil-Immersed LBS​

Provides reliable load breaking and closing functions, integrated in an oil environment to enhance arc extinguishing capability and operational safety.

6.Rotatable Feedthru Insert

Supports flexible wiring and direction adjustment, simplifies installation, and adapts to complex on-site wiring requirements.

7. Bushing Well​

Protects high-voltage bushing connection points, prevents environmental corrosion and physical damage, and ensures electrical insulation performance.

8. Bay-O-Net Fuse

Provides overload and short-circuit protection, rapidly cuts off fault current, and maintains grid stability.

9. Low Voltage Connector​

Enables reliable electrical connection on the low-voltage side, with modular design for quick installation and replacement.

10.Tap Changer​

Allows adjustment of output voltage to adapt to grid voltage fluctuations and optimize power quality.

System Advantages​

High Integration: All components are optimally arranged around the transformer enclosure, compact structure saves installation space.

Intelligent Monitoring: Key parameters (pressure, oil level, temperature) are visible, supporting preventive maintenance.

Safe & Reliable: Multiple protection designs (relief valve, fuse) effectively respond to sudden failures.

Easy Maintenance: Modular components allow quick replacement, reducing downtime and maintenance costs.

| Application​
