Spare electric system for precise manufacturing industry and power supply method thereof

Abstract

The invention discloses a spare electric system for a precise manufacturing industry and a power supply method thereof. The spare electric system comprises diesel generating sets, a commercial power inlet wire device, a dual power supply control cabinet, a low-voltage distribution center, an emergent distribution cabinet, a continuous power supply device, a DC / AC (direct current / alternating current) distribution box, an important IT (information technology) apparatus, a precise machine tool apparatus, a fire fighting system, an illumination system and a lift system which are matched with each other in order to ensure that the important IT apparatus and the precise machine tool apparatus in the precise manufacturing industry out of influence due to the failure or cut-off of commercial power; the power supply mode realizes a continuously power supplying mode; and the electricity safety of the important IT apparatus and the precise machine tool apparatus are ensured. When the commercial power occurs failure or cut-off, the dual power supply control cabinet controls and starts the diesel generating set I; if the diesel generating set fails, the dual power supply control cabinet rapidly starts the dual power supply control cabinet II for power supply, so that the power supply safety and reliability of the whole spare electric system are guaranteed.

Description

technical field [0001] The invention relates to the technology in the field of power systems, in particular to a precision manufacturing backup power system and a power supply method applicable to most precision manufacturing industries. Background technique [0002] At present, the precision manufacturing industry mainly includes precision and ultra-precision processing technology and manufacturing automation. The former pursues the precision of processing and the limit of surface quality, and the latter includes the automation of product design, manufacturing and management. It is not only a rapid response to the market. It is an important means to increase demand, increase productivity, and improve working conditions, and it is an effective measure to ensure product quality. The two are closely related. Many precision and ultra-precision processing rely on automation technology to achieve expected indicators, while many manufacturing automation depends on precision. Proce...

Problems solved by technology

[0003] And safe and stable power is particularly important for the precision manufacturing industry. The instability of power or sudden power outages directly affect the processing quality of precision machine tool equipment, which will cause greater losses in terms of products, and sometimes even damage Precision machine tool equipment causes certain damage; the existing precision manufacturing industry has a wide range of types, its load types are complex, and the requirements for power quality are also different. There is no power supply scheme that can be widely promoted in the market to be suitable for most precision manufacturing industries. Moreover, the existing various power supply schemes cannot meet the actual needs of the existing precision manufacturing industry because it is difficult to accurately and timely realize uninterrupted power supply when the mains power failure or sudden power failure occurs.
