Maximum load of 6 square copper wire:
If it is an open wire, the maximum current can be 50A
Converted to load, the electric heating class is 11KW, the electric class is 7.7KW?
If it is through the pipe or buried in the wall or the jacketed wire, the current is only 41A Converted to load, the electric heating class is and 9KW, the electric class is 6.3KW
Load calculation method has a need for coefficient method, the use of coefficient method, unit index method and so on several kinds.
Need coefficient method. With the power of the equipment multiplied by the coefficient of need and the simultaneous coefficient, the calculated load is directly derived. This method is relatively simple, widely used, especially for distribution, substation load calculation.
Utilization factor method. The use of the utilization factor to find the average load of the largest load class, and then consider the number of equipment and power differences, multiplied by the effective number of units related to the maximum coefficient to calculate the load. The theoretical basis of this method is probability theory and mathematical statistics, so the calculation results are closer to reality. Applicable to a variety of ranges of load calculation, but the calculation process is a little complicated.
Power per unit area method, unit indicator method, unit product power consumption method. The first two are mostly used in civil buildings, the latter for some industrial buildings. In the power of electric equipment and the number of units can not be determined, or pre-design, these methods are the main method of determining the equipment load.
In addition to the use of the above methods, there is the binomial method, as well as the emergence of the abc method in recent years, the variable value of the coefficient of need method. Some of these methods have been replaced by other methods, some are simplified using the coefficient method, and others have little practical data and failed to promote.
