MNS low-voltage drawer type switchgear (hereinafter referred to as switchgear) is developed by our company after referring to Swiss ABB's MNS series low-voltage switchgear and making
comprehensive improvement.The products are composed of standardized, serial modules, and the drawer has a reliable mechanical interlock device, which makes the user safer and more reliable when
using.
The switch cabinet is suitable for use in ac 50 Hz (60), rated voltage 400 v, 660 v, rated current under 5000 a and three-phase five wire of electric power supply system, can be used in power
plants, substations, industrial and mining enterprises, hotel, airport, dock and radio and television communications center, for power generation, transmission and distribution, power conversion
and power consumption equipment control, and through the ark to its main bus-bar capacitance compensation for reactive power compensation.
Conditions of use
1. For indoor use, the elevation of the service point shall not exceed 2000m.
2, the ambient air temperature is not higher than +40 degrees, not lower than negative 5 degrees.The average temperature should not be higher than +35 degrees within 24 hours.When exceeding,
the capacity should be reduced according to the actual situation.
3. The relative high temperature of the surrounding air is +40 ° c and does not exceed 50%, and a large relative temperature is allowed at a lower temperature;If +20 degrees is 90%,
consideration should be given to the effect of occasional condensation caused by temperature changes.
4. When the device is installed, the tilt with the vertical plane shall not exceed 5°, and the whole set of cabinets shall be relatively flat in line with the standard of gbj232-2.
5. The device shall be installed in a place where there is no severe vibration and impact and no corrosion of electrical components is sufficient to use
