Proposed switchgears 6 (10) kV modernization solutions include:
Modernization of medium voltage cubicles 6 (10) kV involves replacement of outdated oil circuit breakers by means of universal module installation with modern vacuum circuit breaker Evolis type.
Structurally universal module is installed on supporting frame. Module delivery set includes transitional busbars and other structural elements, which provide module adaptation to the place of its installation.
Special service trolley is used for convenient circuit breaker Evolis withdrawal from the module.
Circuit breakers Evolis are applied as switching device for distribution and industrial circuits protection and control.
Special configuration of operating contacts in circuit breaker vacuum chambers and axial magnetic field during arc breaking provide arc breaking softness which is maximum possible in this circuit breaker type even at high current values. External coil around contact area generates electromagnetic field.
In addition, circuit breaker Evolis meets the highest requirements to mechanical wear resistance (IEC 62271-100: class М2).
PLUTON offers several versions of the most efficient relay protection replacement tools:
Earthing disconnector is applied for cable inputs earthing before performing works in cable compartment.
Earthing disconnector completely meets IEC 62271-102 and consists of:
