Tips: The effect of high altitude on solar water pumping systemWhen the altitude exceeds 2000m, the use of universal low-voltage electrical appliances will be subject to certain restrictions. In the range of 5000m above sea level, the air pressure is reduced by about 1.07kPa for every 100m elevation. At an altitude of 1000m or above, the temperature drops by an average of 0.6 degrees for every 100m. There are two main effects on the electrical products after the pressure is reduced:
In view of the above two points, high-altitude areas require correction of the dielectric strength related indicators of general-purpose low-voltage electrical products, such as power frequency withstand voltage and impact withstand voltage, electric clearance and creepage distance, etc. The rated capacity of electrical products is also required to be modified.The solar water pumping system is applied in high-altitude areas. For power distribution equipment such as inverter, combiner boxes and control cabinets in solar water pumping systems, the switching elements (DC circuit breakers) used in them are greatly affected by altitude. It is necessary to correct the dielectric strength related indicators. For example, reduce the capacity of input power supply voltage and rated capacity to suit high altitudes.
