The instrument transformer assembly line is a special manufacturing system designed for the efficient and large-scale production of instrument transformer (current transformers CT, voltage transformers PT, etc.), covering full-process automated or semi-automated operations from raw material processing to finished product testing.
I. Key technologies and equipment of instrument transformer assembly line
Automated winding equipment: Supports multi-axis linkage and tension closed-loop control, and can adapt to rapid switching of coils of different specifications.
Epoxy resin pouring system: Including vacuum degassing device and mold temperature control system to ensure uniform pouring without bubbles.
Intelligent test platform: Integrate multi-functional test modules such as transformation ratio, polarity, and insulation, and realize automatic data collection and analysis through PLC or industrial computer control.
Vision inspection system: Used for inspection of appearance defects (such as coil damage, insulation cracks) to improve quality inspection efficiency.
II. Characteristics and trends of instrument transformer production lines
High precision and consistency: Reduce human intervention through automated equipment and ensure that the electrical parameters (such as error levels 0.2S and 0.5S) and mechanical size of each transformer meet standards.
Flexible production: Support multi-variety and small-batch production models, and adapt to the needs of different models (such as low-voltage current transformers and high-voltage voltage transformers) through rapid mold changes (such as replacing winding molds and pouring molds).
Reduction in labor costs: The clear division of labor and automated equipment in the assembly line allow staff to complete work tasks more efficiently and reduce reliance on skilled workers.
