In large power plants, petrochemical systems and other places with high degree of automation and computer interface requirements, it is a complete set of low-voltage power distribution device used for power distribution, motor centralized control and reactive power compensation in power generation and power supply system with three-phase AC frequency of 50 (60) Hz, rated working voltage of 400V and 660V and rated current of 5000A and below.
The design of the device meets the following standards: iec439-1 low voltage switchgear and control equipment, GB7251 low voltage switchgear.
Model meaning
Normal service conditions
⦿ the ambient air temperature shall not be higher than + 40 ℃, not lower than - 5 ℃, and the average temperature within 24 hours shall not be higher than + 35 ℃. In case of over capacity, the capacity shall be reduced according to the actual situation;
⦿ for indoor use, the altitude of the place of use shall not exceed 2000m;
⦿ the relative humidity of the surrounding air shall not exceed 50% when the upper limit temperature is + 40 ℃. A larger relative humidity is allowed when the temperature is lower, such as 90% when the temperature is + 20 ℃. The influence of occasional condensation due to temperature change shall be considered;
⦿ when the device is installed, the inclination to the vertical plane shall not exceed 5 ° and the whole cabinet row shall be relatively flat (in accordance with gbj232-82 standard);
⦿ the device shall be installed in the place without severe vibration and impact and not enough to make the electrical components suffer from corrosion;
⦿ if users have special requirements, they can negotiate with the manufacturer.
