Products Description
Our transformer cooling control system provides manual, automatic, and remote control of cooler groups. Temperature, load, motor status, and fault signals determine operating and standby-cooler actions.
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 control system coordinates several fan and pump groups from one protected outdoor cabinet. Manual, automatic, and remote modes support testing, normal service, and dispatch control. A failed motor can be isolated while other cooling motors remain in operation. Automatic temperature and humidity control protects the internal electrical components.
Operating Conditions
The product shall be installed and operated within the ratings stated in the technical parameters. Key site requirements include: Altitude; Protection grade. Keep the installation area clean, adequately ventilated, free from corrosive gas and severe vibration, and provide the specified grounding, clearance, and power quality.
