Electric cabinet is made of quality steel processing components to protect the normal work of the cabinet, electrical cabinets materials generally divided into hot rolled steel and cold rolled steel sheet, cold rolled steel sheet is relatively hot rolled steel plate material more soft, more suitable for the production of electric cabinet, electric cabinet widely used mainly used in chemical industry, environmental protection industry, electric power system, metallurgy system, industry, nuclear industry, fire safety monitoring, transportation industry, etc., primary distribution equipment, collectively known as power distribution center, concentrate installed in the substation of the enterprise, the power allocated to different locations of the lower power distribution equipment, the level of equipment only on step-down transformer, so the electrical parameters of the demand is higher, the output circuit capacity is bigger also, secondary distribution equipment, power distribution cabinets and motor control center of a general designation, power distribution cabinets used in load more dispersed, loop fewer occasions, motor control center is used to load concentration, loop more occasions, they turn at the next higher level distribution equipment power allocated to the nearest load of a circuit, the level of equipment to load to provide protection, monitoring and control, final distribution equipment all referred to as the lighting power distribution box, they are far away from the power center, is dispersed small capacity distribution equipment.
Based on the technical conditions of the existing electrical cabinets, electrical cabinets in communication range of use and convenience are still many deficiencies, most of the communication, MCC still exists the situation of the high temperature, often due to high temperature equipment malfunction, affect the normal use of equipment, but each electric cabinet cooling device can lead to high cost of installation, simple and traditional electric cabinet structure, use and install all has certain limitation, very inconvenient.
