(1) a distribution device, referred to as the power distribution center. They focused on companies installed in the distribution of electric energy substation to lower distribution equipment in different locations. This level of equipment close to the step-down transformer, so the higher the electrical parameters required, the output circuit capacity as well. (2) secondary distribution equipment, power distribution cabinet is collectively and motor control centers. Power distribution cabinet use in load scattered, small loop occasions; motor control center for centralized load loop more occasions. They allocated on a circuit-level power distribution equipment to the nearest load. This level of equipment to deal with load protection, monitoring and control. (3) The final distribution equipment referred to lighting power distribution box. They are far from the power centers are scattered small-capacity power distribution equipment. By structural features and usage: (1) fixed panel switchgear, often called the switch board or power distribution panel. It is a kind of masking panel open switchgear positive protective effect, back and side still touching the live, low degree of protection can only be used for low power continuity and reliability requirements of the mining industry for substation rooms with centralized power supply. (2) Protection of formula (ie, enclosed) switchgear, refer to the mounting surface in addition, all other sides are closed up in a low-voltage switchgear. Such a switch cabinet, protection and monitoring control and other electrical components are installed in a steel or enclosure made of insulating material, it can be installed against a wall or away from the wall. You can not add each loop between the cabinet and isolation measures can also be used a grounded metal plate or insulating plate isolation. Usually the main door switch operation with a mechanical interlock. There are also shielded station switchgear (ie the console), the panel is equipped with control, measurement, signal and other electrical appliances. Protective switchgear is mainly used for craft-site power distribution equipment. (3) switch cabinet drawer. Such switchgear enclosure made of steel plate, electrical components are installed into the outlet circuit functional units constituting the extractable drawer to complete a certain type of power supply task. Between functional units and bus or a cable, use a grounded metal plate or plastic buses, functional units and three regional cable formed apart. There isolation between each functional unit. Switch cabinet drawer with high reliability and interchangeability security, it is more advanced switchgear, switchgear current production, the majority of switch cabinet drawer
