Product Introduction Non-Excited Pressure Regulating Power Transformer
The 50kVA 10kV Non-Excited Pressure Regulating Oil Immersed Power Transformer is a 3 Phase Oil-immersed Power Transformer designed for medium- and low-voltage distribution systems, ideal for industrial, commercial, and data center applications. Featuring a fully sealed oil-immersed structure, it minimizes leakage risks and enhances operational safety. Its core advantage lies in the integrated Non-Excited Pressure Regulating Power Transformer technology, which stabilizes voltage output during load fluctuations through non-excited pressure adjustment, ensuring consistent power quality.
The Power Transformer's windings utilize high-permeability silicon steel and high-temperature-resistant insulation materials, achieving low no-load losses and high load capacity while complying with international energy efficiency standards. Its compact design reduces footprint requirements, and its IP23 protection rating enables reliable outdoor operation in variable environments. This transformer is a robust choice for upgrading small-to-medium-scale power systems.
Voltage Regulation Mechanism and Features
Working Principle:
The Non-Excited Pressure Regulating Power Transformer employs a non-excitation tap-changer and a pressure-sensing system for voltage regulation. When grid voltage fluctuates, the pressure sensor detects oil pressure changes and triggers the controller to switch the tap-changer to a preset position, adjusting the winding turns ratio to stabilize output voltage within ±5%. This process is performed in a de-energized state (non-excited), ensuring safe and reliable operation.
Key Features:
Precision Voltage Regulation: Rapid pressure adjustment responds to sudden industrial load changes or grid fluctuations, maintaining stable output in the 3 Phase Oil-immersed Power Transformer.
Low Maintenance: The fully sealed structure and pressure compensation system minimize oil exposure to air, reducing oxidation and moisture ingress, extending the Power Transformer's lifespan to over 25 years.
Energy Efficiency: Optimized winding alignment and high-quality insulating oil reduce no-load losses below IEC 60076 standards, significantly cutting operational costs.
Environmental Resilience: Tested for operation in temperatures ranging from -30°C to +50°C, the Non-Excited Pressure Regulating Power Transformer's tap-changer also features dustproof and waterproof capabilities.

Complete Installation Guide Non-Excited Pressure Regulating Power Transformer
1. Preparations
Ensure the installation site is level and vibration-resistant, with adequate space for the Power Transformer (dimensions: 120cm × 80cm × 150cm).
Verify grounding system compliance and prevent metallic dust exposure to the Non-Excited Pressure Regulating Power Transformer's housing.
2. Lifting and Positioning
Use a forklift or crane to hoist the 3 Phase Oil-immersed Power Transformer onto the foundation.
Calibrate alignment with a leveling instrument (leveling error ≤2°) to prevent oil leakage due to uneven oil levels.
3. Wiring and Sealing Inspection
Connect busbars according to the wiring diagram for the high-voltage side (10kV) and low-voltage side (0.4kV).
Tighten bolts to specified torque values using a torque wrench.
Inspect all sealing gaskets and observation windows to ensure no leaks in the oil-immersed environment.
4. Oil Level and Pressure Adjustment
Refill insulating oil through the filling port until the oil gauge reaches the midpoint.
Test system sealing by activating the pressure relief valve.
Recheck oil levels after 24 hours and adjust to the standard range if necessary.
5. System Testing
Insulation resistance test (≥1000MΩ).
Withstand voltage test (1.5x rated voltage without breakdown).
Tap-changer verification (voltage regulation accuracy of ±1%).
Load test (temperature rise/noise levels comply with standards).
