I am confused about these names. Please give the experts an explanation. Thank you!
Industrial low-voltage power supply process: 10KV- high voltage power distribution measuring cabinet - transformer - low voltage power distribution cabinet - workshop power switch cabinet - workshop, electrical control cabinet, the tasks are not the same as each.
Power Distribution Box：The switchgear, measuring instruments, protective appliances and auxiliary equipment are assembled in a closed or semi enclosed metal cabinet or screen according to the electrical wiring requirements to form a low-voltage distribution device. During normal operation, the circuit can be switched on or off by manual or automatic switch. In case of malfunction or abnormal operation, cut off electric circuit or alarm with protective appliance. By using the measuring instrument, various parameters in the operation can be displayed, and some electrical parameters can be adjusted to indicate or send signals to deviate from the normal working state. Commonly used in hair, distribution and substation.
Power box:As I understand it, the upper control box of the load!
Switch cabinet：Switch cabinet is a kind of electric equipment. The outside line is advanced into the main control switch inside the cabinet, and then enters the control switch, each branch is set according to its need. Such as the instrument, automatic control, motor magnetic switch, various AC contactor, have also set up a high pressure chamber and a low pressure chamber is provided with a high voltage switchgear, busbar, such as power plants, some also equipped with low zhoubao main equipment load reduction
Electric control cabinet：As the name suggests, it is the power control cabinet!Switch box:It should be relative to the switch cabinet. It's a low voltage device!
