Current transformers (CT) are key equipment used in power systems to convert large current into small current (usually 5A or 1A) for use in measuring instruments, relay protection devices and automation systems. Current transformers can be divided into electromagnetic types (feedthrough type, pillar type, sleeve type), electronic types (such as Rogowski coil, low power core type) and other types according to their structures, among which electromagnetic types account for the highest proportion.
Current transformer assembly line process characteristics
1. Automation and standardization: Robots or CNC equipment are used in key links (such as winding, glue filling, and testing) to reduce manual errors; consistency of batch products is ensured by unifying tooling and parameters (such as winding tension, curing temperature).
2. Online quality traceability: Each product is bound with a unique QR code to record various process parameters (such as core annealing time and test data) to facilitate subsequent quality traceability.
3. Flexible adaptation: By adjusting equipment parameters (such as number of winding turns, mold size), the production of transformers of different specifications (capacity, accuracy level) can be quickly switched.
