SCB12-2500KVA dry-type transformer is mainly composed of iron core composed of ferrite core and epoxy resin glue poured inductance coil, high-voltage and low-voltage electromagnetic coil in the middle of the insulating tube to enhance electrical insulation, and then supported by the backing plate tube bundle electromagnetic coil, the standard parts connected by its parts have fastening characteristics. SCB12-2500KVA dry-type transformer has the characteristics of strong short-circuit resistance, small maintenance labor, high efficiency, small size, low noise, etc., and is mainly used in sites with high requirements for fire safety and explosion-proof characteristics.

SCB12-2500KVA dry-type transformer structural characteristics:

(1) Solid insulating wrapping winding

(2) Do not wrap around the resistance

Winding: Among the two types of winding, the relatively high working voltage is the high-voltage winding, and the relatively low is the low-voltage winding.

From the perspective of the position relationship between the high and low voltage windings, the high pressure can be divided into the same boat type and the overlapping type.

The Tongzhou type winding resistance is simple, the production and manufacturing are convenient, and all of them adopt this kind of structural form.

Overlapping type, mainly used in special transformers.

SCB12-2500KVA dry-type transformer characteristic structure

1. Temperature controller

The safe operation and service life of dry-type transformers mainly depend on the safety and stability of the transformer winding insulation.

2. Heat dissipation mode

The heat dissipation mode of SCB12-2500KVA dry-type transformer is divided into evaporative cooling (AN) and forced evaporative cooling (AF). Of course, when air-cooled, the transformer can operate continuously for a long time from the short-circuit capacity. When forced to be air-cooled, the output volume of the transformer can be increased by 50%. Applicable intermittent overload operation, or emergency safety accident overload operation; Because the load loss and impedance voltage increase are relatively large when overloaded, and they are in non-operating mode, they cannot be kept in long-term continuous overload operation.
