Abstract
With the new round of sustained and rapid economic growth, electricity load demand is also growing rapidly, in order to improve power terminal energy''s convenience, flexibility and reliability, particular attention to the selection of low voltage distribution switchgear. Low-voltage apparatus is an important basic components of the modern industrial process automation, can be seen everywhere in the industrial control, and with our daily lives. It is the foundation and an important guarantee for Low-voltage power system reliable and safe electricity, and has an irreplaceable position and role in the national economy. Low-voltage apparatus is widely used, large, wide variety in the national economic sectors and people''s lives. Low-voltage apparatus play a role in controlling, adjusting, detecting, protecting, exchanging electricity’s production, transmission, distribution and application. Based on the Sino-Germany Hangzhou SIMAX Electric CO., LTD Xiangyushangcheng electrical Distribution System Engineering''s design, by selecting of common low-voltage apparatus in electrical equipment, for example isolation switch, low-voltage circuit breakers, contactors, thermal relays, fuse and so on, accomplish the design of the fan control box.
Key words: low-voltage power distribution; low-voltage apparatus; complete sets of equipment; fan control
