Core Advantages of Non-excited Voltage Regulating Distribution Transformer
1.Accurate Voltage Regulation & High Efficiency Stability
Designed as a Double-winding Non-excited Voltage Regulating Distribution Transformer, it supports rapid voltage regulation without excitation, achieving voltage regulation accuracy of ±2.5%, adapting to complex grid environments.
Oil-immersed insulation technology enhances heat dissipation efficiency; full-load temperature rise is below national standard requirements, ensuring reliability under high load conditions.
2.Robust Structure & Environmental Adaptability
This voltage regulating transformer uses an integral sealed box body to prevent dust and moisture, with built-in pressure relief valves and multi-layer insulation protection, suitable for highly corrosive or high-altitude environments.
The adjustable installation base is compatible with transformers of different specifications, supporting quick positioning and shock absorption, reducing transportation and installation complexity.
3.Intelligent Features & Low Maintenance Costs
Integrated intelligent temperature control system monitors winding temperature and oil level in real time, warning of abnormal conditions.
Equipped with cleaning and bird-proof devices to reduce external interference and lower maintenance frequency.
Application Scenarios
Industrial Manufacturing: Provides stable power for factory production lines and metallurgical equipment.
Public Grids: Substation upgrades or expansions optimize regional distribution efficiency.
Data Centers: Supports high-reliability power supply, ensuring server cluster operations.
Infrastructure Projects: Configured
Installation Instructions
1.Installation Type
This Oil-immersed Distribution Transformer supports multiple installation methods for different scenarios:
Pole-mounted / Outdoor Installation: The equipment must be securely anchored to a reinforced concrete foundation to ensure structural stability.
Indoor Installation: It is recommended to align the front of the cabinet with the distribution panel, maintaining close contact and reserving adequate ventilation space for the Voltage Regulating Distribution Transformer.
2.Installation Steps
Positioning and Fixation:
Use designated force points for precise positioning and adopt anti-slip measures to ensure device stability.
During transportation and installation, strictly control the tilt angle: longitudinal ≤15°, lateral ≤10°, to avoid structural deformation.
Component Adjustment:
Inspect component clearances to avoid over-tightening or looseness that could cause transformer operational abnormalities.
When installing terminals, choose the appropriate type of insulating pad based on actual needs to ensure correct wiring and reliable insulation.
Final Commissioning:
After completing the basic installation, inject transformer oil that complies with IEC standards and let it sit for 24 hours.
Conduct insulation resistance tests and power frequency withstand voltage tests to confirm the normal operating parameters of the Voltage Regulating Distribution Transformer.
3.Attachment Installation Specifications
All attachments (such as gas relays, pressure relief valves, desiccants, bushings, etc.) must strictly follow the following requirements:
Standardized Operations: Follow relevant national standards and the manufacturer's technical manual.
Sealing and Protection: Ensure that attachment interfaces are tightly sealed to prevent leaks or foreign object intrusion.
Function Verification: After installation, check each attachment function one by one (e.g., sensitivity of the pressure release device) to avoid safety hazards.
