MVnex500

Summary

The MVnex500 switchgear adopts a metal armored design, and each functional compartment is relatively independent. The main circuit of the switchgear is fixedly connected and equipped with high-performance HVX sealed vacuum circuit breakers Reliable three position switch. The three position switch has working, isolating, and grounding positions, and the switch status can be directly seen through the observation window in front of the cabinet.

A complete mechanical locking mechanism is installed between the circuit breaker and the three-position switch, completely avoiding accidental operation caused by carelessness or lack of understanding of the equipment by operators. At the same time, full consideration was given toAccording to the power distribution scheme requirements, the MVnex500 switchgear can be equipped with flexible electrical interlocking schemes to achieve interlocking between cabinets, upstream and downstream, ensuring the safety of operators, distribution equipment, and distribution systems.
