The load value is obtained by statistically calculating the load. The load value of the components used in the power supply system is called the load according to the heating conditions. <br>(1) The calculated load is also called the required load or the maximum load. The calculated load is a hypothetical continuous The maximum thermal effect of the load, whose thermal effect is the same as the actual situation of the enterprise, is the same as the maximum thermal effect produced by the changing load per unit time. In the design of the distribution system, the maximum average working load of 30 minutes can usually be used as the heating condition to select the distribution transformer and The basis of electrical conductors, and used to analyze different voltage loss and power loss. It is convenient for engineering calculations, and can also be used as the basis for calculation of power consumption and reactive power compensation. <br>(2) The peak current is a single or multiple electrical safety devices lasting about 1 s The starting current component of the current cycle of the maximum working load is usually used for the calculation of the voltage loss of voltage fluctuations and voltage drops, and the selection of electrical appliances and components.
