NEX switchgear is designed with due regard to the long experience of similar devices operation and meets basic requirements: reliability required for trouble-free operation, easy operation and maintenance, as well as personnel safety.
NEX is manufactured in 44 factories of 17 countries all over the world. Your local partner PLUTON provides the advantages of local production and service for internationally known product. Quality of the product is guaranteed by Schneider Electric (France) due to training, technical support and regular audit of the certified partner PLUTON.
NEX integrates innovative solutions based on proven techniques and includes: high performance switchgear, digital protection, monitoring and control systems.
NEX cubicles are structurally protected against destructive influence of internal arc and provide safety of maintenance personnel. Immunity to internal arc is confirmed by localization property type tests. Internal arc detector — an electronic module with optical sensors can be optionally installed in NEX.
NEX cubicle integrates mechanical and electromagnet interlocks to prevent incorrect operation by personnel and ensure safety in case of:
Locks are additionally provided.
Cubicle is made up of 4 compartments separated internally with metallic partitions:
NEX meets IEC 62271:200 requirements. It provides LSC2B safety class and this allows operations in separate compartments without voltage removal.
NEX includes Evolis vacuum circuit breaker manufactured by Schneider Electric (France) as a switching device:
Special configuration of operating contacts in circuit-breaker vacuum chambers and axial magnetic field during arc breaking provide maximum possible in this type of circuit-breakers "softness" of arc breaking even at high current values.
Evolis corresponds the highest mechanical endurance requirements (IEC 62271-100: class M2).
Earthing switch is used to earth cable leads before starting works in cable compartment. Earthing switch earths the switchgear busbar in voltage transformer functional module.
Earthing switch corresponds IEC 62271-102 and consists of:
Protection, control and monitoring system ensures:
The system includes:
