MVnex Smart (Smart)

MVnex Smart MV switchgear is a smart solution specially designed

for users who need highly reliable continuous power supply, while

maintaining the design concept of Schneider Electric's MVnex metal-

clad enclosed switchgear. It is suitable for users of smart grid (switching

stations, power distribution rooms, etc.), data centers, hospitals, airports,

military sites and other industry users.

MVnex Smart can be customized based on customers' on-site

environment so as to provide solutions with smart design meeting the

system requirements, which can be equipped with more optimal online

monitoring, protection, control and digital system. It also has highly

reliable arc protection device and sequential control function, thus

meeting the demands of digital operation and maintenance through the

automation and software functions from Schneider Electric.

Civil Construction Configuration and Installation

Basic Layout Plan of Power Distribution Room According to the technical characteristics of MVnex switchgear, it is suggested that the appropriate space should be set between the

rear cover as well as both sides of the switchgear and the wall as the maintenance channel.

Figure 1 shows the reference scheme of the power distribution room layout, which can be referred to for those adopting the cable trench incoming manner, the lower cable outgoing manner, or the upper cable outgoing manner. The figure only shows the single-row switchgear layout. If the switchgears are in double-row face-to-face arrangement, the distance between two rows shall not below 2500mm.

Foundation Frame of Switchgear

The installation of the switchgear foundation frame shall comply with the provisions of technical specification about construction and acceptance of electric power facilities. No matter which incoming/outgoing manner is adopted, pre-processed channel steel is recommended as switchgear foundation frame.

The height of the foundation frame channel steel shall be reserved with margin left when the base elevation of the switchgear is designed (see Figure 2), and anchoring steel plate shall be laid every 1 to 1.5 meters along the longitudinal direction of the framework on the switchgear base.

The foundation frame is welded with channel steel. The basic requirements on dimensions of the frame and the layout of the frame are shown in Figure 3, with no strict requirement on the height of channel steel. The extension distance of the channel steel of the foundation frame should be the same with the size of the switchgear framework. The total length of the framework depends on the layout and number of the switchgears in each row.

Level calibration shall be conducted for the foundation frame during embedding, with the error of levelness and straightness shall not exceed 1 mm per meter, while the total error 2mm. The top surface of the basic framework is required to be about 3-5mm higher than the final terrace of the power distribution room.
