Learn and master the general process of selecting low-cost distribution box to help readers successfully complete the task of power engineering design.

Correct selection of power station is an important condition for safe and economic operation of main electrical wiring and distribution board. The selection of equipment is usually carried out after the operation of determining the main wiring or basic wiring mode is completed. Different system wiring modes have a great impact on the determination of equipment.

When selecting the equipment, it is necessary to adopt new technology actively and reliably, pay attention to saving investment and select the right power station on the premise of safety and reliability according to the actual situation of the project.

Correct selection of equipment is an important condition for safe and economic operation of main electrical wiring and distribution equipment. The functions and working conditions of various power stations in power system are different, and the specific selection methods are also different, but the basic requirements are the same.

In order to make the power plant work reliably, we need to go through strict selection processing: (1) make the initial selection under normal working conditions（ 2) Correction in normal use environment (about initial selection)（ 3) Check based on extreme abnormality (short circuit state) (thermal stability and dynamic stability).
