Completely Self Protected Transformers Class II Pollution CSP Technology

5 0 Reviews
SCP series fully automatic protection pole mounted transformer, the transformer refers to polemounted transformer high side and low-sideconfiguration with some protection components, so asto protect the transformer and network security. Fullyautomatic single-phase transformer on lightningprotection, short-circuit and overload protection canplay its own role, to protect the transmission anddistribution lines not because of their own transformerfailure caused by power outages.

CSP Technology

We equipped several components, in order to create the CSP transformer.

These components when applied to the transformer during its manufacturing process, provide multiple layers of protection.

Outline drawing High Voltage Fuse

Acts as over current protection by isolating the faulty transformer from the network. It is mounted inside of the transformer and it is connected between the incoming high voltage lead from the bushing and the high voltage line lead from the transformer primary winding.

Overload Indicator

Provides visual indication of abnormal loading conditions. The signal light is mounted on the exterior wall of the transformer tank near the operating handle of the circuit breaker. The signal light is electrically connected to the signal light sensing circuit within the transformer.

Low Voltage (Secondary) Circuit Breaker

Provides secondary fault and overload protection. The circuit breaker is mounted

inside of the transformer and it is connected between the secondary winding and secondary bushing, such that the current flows through the circuit breaker
