Low voltage power distribution ark market demand

Date:2017/2/7 16:06:16      Viewed:

Domestic recent development is rapid, high and low voltage power distribution ark after half a century of development and research, has now formed a relatively complete system, the performance of the low voltage power distribution ark has been from the earliest now play standard, large volume, low, small capacity and single function, specification variety, less development for high performance, small volume, electronic, intelligent, modular and multi-functional characteristics of the product.

1. In the 1950 s to introduce domestic distribution cabinets, introduced from abroad the characteristics of the power distribution cabinet:
1.1 the equipment in the design of the cabinet put oneself in another's position, the equipment fault arc protection ability, processing technology, power distribution cabinet has poured the first intelligent level, there is a big breakthrough in technology and foreign companies set up to realize centralized monitoring in low voltage power supply system, on the basis of actively carry out intelligent low voltage switch and the study of the intelligent power distribution cabinet.
2.2 in terms of design, each big manufacturer has taken a CAD software for 3 d design, calculation and analysis, database design, and at the same time processing such as organically, to a great extent improve the design speed and can book, and reduces the labor intensity of the relevant technical staff.In terms of equipment fault ability, complete sets of switch equipment failure is the bottleneck of technology, foreign big companies always committed to the technology research and development.In general, the dry arc fault current value is less than the main switch moment of a fixed value, in this situation, the protection of the conventional hard to quickly disconnect the arc current.
