As power systems continue to develop toward intelligence and digital operation, intelligent transformers have become essential equipment in modern power grids, renewable energy projects, and smart substations. Compared with conventional transformers, intelligent transformers require higher manufacturing accuracy, stronger quality consistency, and complete data traceability.

To meet these requirements, manufacturers are increasingly adopting intelligent transformer production lines equipped with automated testing and real-time monitoring functions. These production lines not only improve manufacturing efficiency, but also ensure stable product quality throughout the entire production process.

Core Equipment in an Intelligent Transformer Production Line

Automatic Winding and Insulation Equipment

Automatic winding equipment is the foundation of intelligent transformer manufacturing. CNC winding machines and foil winding machines are used to ensure accurate conductor placement and consistent coil dimensions. An automatic tension control system continuously adjusts winding tension, reducing mechanical stress and preventing insulation damage.

Automatic insulation paper and insulation board wrapping devices ensure precise positioning and uniform insulation thickness, which directly improves dielectric reliability and long-term operational stability.

Core Processing and Stacking System

Core processing systems combine automatic shearing and stacking equipment to achieve standardized core assembly. Laser measurement systems inspect core dimensions in real time, while automatic positioning mechanisms ensure accurate alignment during stacking. This reduces no-load losses, vibration, and operational noise.

Vacuum Drying and Oil Injection System

Vacuum drying systems remove moisture from windings and insulation structures under controlled temperature and vacuum conditions. This process is critical for improving insulation strength and extending transformer service life.

Online oil monitoring and filtration systems continuously control oil quality during production. Automatic oil injection devices precisely manage oil filling speed and volume, ensuring complete impregnation and preventing air pockets.

Automated Testing System

Automated testing equipment is integrated directly into the production line. Key electrical tests such as turns ratio, polarity, phase verification, DC resistance measurement, partial discharge testing, power frequency withstand voltage testing, and temperature rise testing are completed efficiently and accurately.

All test results are automatically recorded and stored as digital reports, forming a reliable basis for quality evaluation and product traceability.

Intelligent Monitoring and Data Management System

An MES-based monitoring system connects equipment, production processes, and testing data into a unified digital platform. Real-time monitoring allows operators to track key process parameters and respond quickly to abnormal conditions.

Alarm functions and remote traceability tools help manufacturers identify problems early and implement corrective actions without interrupting production.

Intelligent Transformer Manufacturing Process

The intelligent production line connects all manufacturing stages through digital management. Production begins with raw material warehousing and identification using barcodes or RFID technology, ensuring accurate material tracking.

Core cutting, stacking, and winding are performed automatically with online inspection. After winding, coils undergo vacuum drying and insulation treatment. Final assembly and lead connection are followed by vacuum oil filling and tank sealing inspection.

Before shipment, automated performance testing is carried out and all production data is stored in the system, enabling complete digital quality traceability.

Automated Testing and Quality Control Technology

Testing functions are embedded throughout the manufacturing process. Electrical parameters are monitored during winding, mechanical assembly accuracy is verified during installation, and insulation performance trends are tracked during drying and impregnation stages.

The testing system applies an adaptive testing strategy. When abnormal data is detected, additional tests are automatically performed. For stable products, testing procedures are optimized to improve production efficiency without compromising quality.

Non-contact testing technologies such as machine vision, ultrasonic inspection, and laser measurement are widely used. These methods improve inspection speed and accuracy while avoiding damage caused by physical contact.

Intelligent Monitoring and Lifecycle Management

The intelligent monitoring system provides real-time quality warnings when key parameters exceed predefined limits. Alerts are delivered immediately, allowing rapid response and corrective action.

By analyzing historical production data, the system continuously optimizes process parameters and adapts to changes in materials and operating conditions. Equipment health management functions predict potential failures and support preventive maintenance planning.

Each transformer is assigned a unique digital identity that links all production data, test results, and process parameters. This enables full lifecycle traceability from raw material procurement to operation and maintenance.

An intelligent transformer production line with automated testing and monitoring functions provides a reliable foundation for modern transformer manufacturing. By combining automation, digital control, and data-driven quality management, manufacturers can achieve higher efficiency, stable product quality, and long-term operational reliability.
