The MV-CS (Medium Voltage Control System) is a combination of technologies and voltage levels. The most prominent feature of this switch gear is the strict division into two components. The basic unit contains the system cabinet, the energy distribution components and the cable connection compartment. All components are passive units and therefore subject to a minimal risk of failure. The single sections are insulated from each other and the connection to the busbar possesses an integrated shutter mechanism. An intelligent decompression channel guarantees a safe release of gases in the case of an internal arc. The slide-in withdraw unit includes all electric relevant components for each possible option. Therefore 99.99% of all failures within the system are appearing in the slide-in.
The system is standardized and has two integrated busbar systems, thus system redundancy is possible without any additional components. Low voltage componentsare integrated in the withdraw unitand are automatically separated with it from the basic unit. All customer cables are fitted into the terminal block located in the basic unit framework. Every withdraw unit has a touch screen which offers operator convenience. Starting from parameter settings across the real value display all the way up to the supportive error analysis, the ease of use covers all requirements.
When the system is inserted, the locking bolts of the basic unit interlock with the door’s framework on all sides. After complete locking of the front door, the system complies with the IEC internal arc test requirements. Forall incurring works the withdraw unit can be completely removed making it accessible from all sides. Furthermore the withdraw unit can be rolled, allowing for maintenance to be done at a comfortable place, like the workshop. Single withdraw systems can be interchanged, while the other system components continue to work at their usual level. When highest system availability is required, the complete withdraw unit can be replaced within minutes.
