适用范围：This part of IEC 60076 applies to high-voltage/low-voltage self-protected liquid-filled andnaturally cooled transformers for rated power 50 kVA to 1 000 kVA for indoor or outdoor usehaving a– primary winding (high-voltage) with highest voltage for equipment up to 24 kV;– secondary winding (low-voltage) with highest voltage for equipment of 1,1 kV.These transformers are equipped with a self-protection and disconnection device to protectthe environment, property and people and prevent any disturbance of the high-voltagenetwork from the consequences of an internal transformer fault.Transformers covered by this standard comply with the relevant requirements prescribed inthe IEC 60076 series.The self-protected transformer may be used in conjunction with other devices to providesystem coordination and sensitive system protection. The protection system is not designedto be functional when the power supply is from the low-voltage side. The self-protectedtransformer is not intended to function in parallel with another transformer.NOTE This standard may be applied to transformers with a higher voltage than 24 kV or other rated power byagreement between the manufacturer and the purchaser. Validation tests should be carried out at the appropriatelevel.
