Grade distribution cabinet distribution cabinet in the power supply system for large-scale, low-voltage power distribution equipment manufacturer, will be divided into different levels in order to better control the distribution. Generally speaking, in the power supply system will be the primary, secondary and lower, this three distribution equipment. Level distribution cabinet power distribution center is powered system, which will be installed in the substation, low-voltage distribution cabinet, responsible for the distribution of electricity to the secondary power distribution cabinet. A distribution cabinet functions required to have a higher electrical parameters, a distribution cabinet structure is more complex, the output of the circuit capacity is also large. Undertake a secondary distribution cabinet distribution cabinet distribution of electric energy, and assigns it to the nearest load. Distribution cabinet is divided into two power distribution cabinet and motor control centers, both opposite the site of application, power distribution cabinets used in small loops, load distribution site, and motor control centers applied to the loop more load concentration area . Below based on practical experience, the following points: 1. The import distribution cabinet is developed abroad, usually for the global supply and distribution market. Due to the requirements of each country for the distribution system and habits are not the same, so the import and distribution cabinets do not necessarily apply in the domestic market. 2. The main electrical components used in distribution cabinet imports are imported brand products, some cabinet or some cabinet accessories must be imported, low-voltage distribution cabinet offer, resulting in the import and distribution cabinet so than the general domestic prices much higher distribution cabinet. 3. imported distribution cabinet technical parameters, although high, but in most cases only a part of the application, or even simply can not use. For example Loop import distribution cabinet can be installed in a cabinet than the domestic distribution cabinet are more, but that is the premise of reducing the capacity of the circuit to achieve low-voltage distribution cabinet company, in most cases failed to meet user needs. Technical parameters 4. Domestic distribution cabinet distribution cabinet although lower than imports, but most of the domestic power supply system has been able to meet user needs. 5. On the quality of power distribution equipment, as long as 3C manufacturers in strict accordance with the requirements of production, examine the quality of domestic distribution cabinet is not necessarily worse than the quality of imported distribution cabinet.
