Voltage Transformer Assembly Line

1. Classification and main structure of voltage transformers

Voltage transformers are mainly divided into two categories according to the principle, and their structure and production process are slightly different:

1.Electromagnetic Voltage Transformer, EVT

Based on the principle of electromagnetic induction, it mainly consists of iron core, primary/secondary windings, insulating parts (such as oil-impregnated paper, epoxy resin), shell (porcelain sleeve or composite material), etc., and is suitable for medium and high voltage (10kV~1000kV) systems.

2.Capacitive Voltage Transformer, CVT

It consists of a capacitive voltage divider (multi-stage series capacitor) and an electromagnetic unit (intermediate transformer, compensation reactor). It is suitable for higher voltage (110kV~1000kV) systems and has both voltage dividing and isolation functions.

2. The core process of the voltage transformer production line

The assembly line design needs to focus on "component processing → assembly → testing → packaging", and each link needs to be highly coordinated to ensure product quality and production efficiency.

3. Automation and intelligence of the assembly line

Traditional assembly lines rely on manual operations, which is inefficient and has poor consistency. Our voltage transformer production line enhances competitiveness through the following technologies:

  Robot application: winding, assembly, handling links into industrial robots (such as six-axis robot arm), accuracy up to ±0.1mm, reduce human error.

  On-line detection integration: laser rangefinder (core stack thickness), infrared camera (local overheating), X-ray flaw detection (internal defects) embedded in the assembly process, real-time rejection of unqualified products.

Winding machine: automatic winding, improve production efficiency and quality.

Test system: Automatically performs performance testing to ensure product quality.

Structural design adaptation: Porcelain sleeves (high aluminum porcelain/composite sleeve), electromagnetic units (independent/integrated), connection terminals (European standard/American standard) and other components support rapid replacement, and production line adjustment will be completed within 48 hours.
