Product Introduction
The SCB11 epoxy cast dry-type transformer redefines safety and reliability. This eco-friendly, flame-retardant transformer can be directly installed at the load center. Its maintenance-free, user-friendly design offers superior moisture resistance, allowing for immediate operation post-shutdown without pre-drying. Key Features: low loss, minimal local discharge, reduced noise levels, and the capability to operate at 120% rated load under forced air cooling. An advanced temperature protection control system ensures safe, reliable performance, adhering to domestic advanced standards of reliability.
The advanced temperature control system features a temperature controller and a PTC temperature measuring element located at the hottest point of the low-voltage winding. This system precisely monitors and regulates the transformer's temperature. In case of overheating due to overload or fault conditions, the controller triggers an alarm and automatically disconnects if the temperature exceeds safety thresholds. During forced air cooling, the temperature controller adjusts the cooling fan based on the winding temperature.
The temperature display system offers real-time visibility of the winding's hot spot temperature during transformer operation, seamlessly integrating with the temperature control system for enhanced monitoring.
The temperature control and display systems offer versatile installation options, including remote setup from the main transformer body. The length of the temperature measuring element's lead wire is:
Temperature Control:<20m
Temperature Display:<10 m (two-wire system)
<100m (two-wire system with compensating wire)
