Resin Storage and Metering System for Transformer Impregnation

Product Specifications

Technical details and manufacturing context for Resin Storage and Metering System

Definition

The Resin Storage and Metering System is a component of the Modular Transformer Core Assembly and Impregnation System. It is responsible for the safe storage, conditioning, and accurate volumetric or gravimetric dispensing of impregnation resin onto transformer cores prior to curing. The system typically includes sealed storage tanks to prevent resin contamination or premature curing, pumps to transfer resin through heated lines to maintain viscosity, and a metering unit (e.g., positive displacement pump, flow meter, or weigh scale) that precisely controls the amount of resin dispensed based on pre-set parameters for the specific transformer core being processed. Key specifications include a rated capacity of 500–2000 liters, metering accuracy of ±0.5%, flow rate range of 5–50 L/min, operating pressure of 1.0–1.6 MPa, temperature range of 20–80 °C, power supply of 380 V AC ±10%, 50 Hz (per IEC 60038), control voltage of 24 V DC ±10% (per IEC 61131-2), ingress protection of IP54–IP65 (per IEC 60529), and wetted parts made of 304/316L stainless steel (per ASTM A240). The system weighs approximately 800–1500 kg and requires a footprint of 2.5–4.0 m². These values are reference ranges and must be verified for the actual model and application. The system is designed for integration into transformer manufacturing lines, with interfaces for PLC control and sensors. Selection inputs include resin type, batch size, and impregnation cycle requirements. Verification questions should address compatibility with specific resin formulations, environmental conditions, and installation constraints. Maintenance signals include deviations in metering accuracy, pressure drops, or temperature fluctuations. Failure boundaries include operating outside the specified pressure, temperature, or flow ranges, which may affect dispensing accuracy or system integrity. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The system stores resin in sealed tanks to prevent contamination or premature curing. Pumps transfer resin through heated lines to maintain optimal viscosity. A metering unit, such as a positive displacement pump, flow meter, or weigh scale, precisely controls the amount dispensed based on pre-set parameters for the specific transformer core. The system operates within specified pressure, temperature, and flow ranges to ensure consistent resin-to-hardener ratio and batch size.
