Designed to control transformer air-cooling fan motors.
Schematic diagram of the automatic control cabinet blowing CB-2 provides:
- local blast management with cabinet panels;
- remote control of blast with control panel;
- automatic control by transformer load current;
- automatic control by temperature of the upper layers of oil;
- The automatic control cabinet blast CB-2 is a welded box with lockable door.
Inside the CB-2 cabinet, an automation panel with located on her control devices. The automation panel is mounted inside the cabinet to back wall. On the panels placed equipment and output clamps.
With increasing temperature of the upper layers of oil above +55ºС the transformer cooling system turns on. With a subsequent decrease in temperature below+50ºС the cooling system is shutting down.
The cooling system also turns on at a load current above 1.05 from rated.
