DC traction networks require safe powerdistribution and reliable control systems. The MB panel contains proventechnology components and is based on the Secheron traction DC protectionexperience. The DC switchgear serves as control and protection equipment forthe power distribution, and consists of incoming cubicle (also called positivecubicle), feeder cubicle and negative cubicle etc.
Features
1. High protection level and perfectsolution.
2. Lightweight and smooth push type trolleywith HSCB, breaker command and LTD is easy for maintenance.
3. Disconnecting or reversing switches withsafety interlock are accessible easily and convenient for operation andmaintenance from the cubicle front or rear side.
4. The integration of protection andcontrol system allows both remote control and monitoring from the tractionnetwork control center.
5. New high-speed connection techniquemakes the connection between cubicles more convenient.
