Products Description
Our transformer cooling automation system collects transformer temperature, load, power, and motor status before applying programmable cooler logic. Dual bus sections, modular I/O, and communication interfaces support dependable operation.
Technical Principle
Temperature, load, oil-flow, fan, and pump feedback are collected by the controller. Programmed logic starts, stops, rotates, and transfers cooling groups according to configured thresholds while issuing fault alarms and recording operating status.
Product Features
The transformer cooling automation system uses programmable logic to balance working, auxiliary, and standby cooler groups. Staggered starts reduce simultaneous motor inrush and allow timed group sequencing. Independent bus sections preserve control capability if one section has a fault. Expandable I/O and networking support future signals and distributed supervision.
Operating Conditions
The product shall be installed and operated within the ratings stated in the technical parameters. Key site requirements include: altitude ≤2500 m. Keep the installation area clean, adequately ventilated, free from corrosive gas and severe vibration, and provide the specified grounding, clearance, and power quality.
