In fact, it is very trance to read article 4.1.4 directly..
IX.
Looking at item 3.1.2 above, are you a little confused? It clearly states the requirements for level-1 load, and also specifically states that level-1 load should have special load.
The following mandatory provisions related to engineering construction standards shall be abolished at the same time: I.
Gov.cn) and published by China Construction publishing media Co., Ltd.

IV.
Articles 6.1.7, 7.2.1 and 9.1.4 of code for electrical design of sports buildings (jgj354-2014).
The following article is the repealed civil standard article: the red box article above is consistent with article 6.2.7 of the code for fire protection design of buildings gb50016-2014 (2018 Edition).
This specification is published on the portal website of the Ministry of housing and urban rural development (www.mohurd.
The interpretation of the new specifications of the Ministry of housing and urban rural development on March 10, 2022 is shown in the red box above, which clearly indicates that attention should be paid to avoiding deformation joints when selecting the location of strong and weak motor rooms; The concept of “special load” in article 3.1.1 of the above figure is proposed for the first time, and the following article 3.1.3 specifies that “special load” is powered by three power sources, consisting of two power sources + one emergency power source meeting the first level load; For buildings with a height of more than 150 meters and above, the emergency power supply can only be provided by self-contained diesel generator sets.

article 4.1.1, 8.2.5 (10), 9.2.1 (3) and 9.3.1 (2) of code for construction of Intelligent Building Engineering (gb50606-2010).
This one makes me feel like a trance.
In the above 4.1.1 and 4.1.4, the standby power supply is relative to the common power supply.
Source: Lao Wang and you talk about the general specification for building electrical and intelligent gb55024-2022, which will be implemented from October 1, 2022.
If such special load exists, the highest load level of a project should be special load.
Article 12.0.2 and 22.0.4 of code for acceptance of quality of Intelligent Building Engineering (gb50339-2013).
articles 3.2.1, 3.2.8, 3.3.4, 4.3.5, 4.7.3, 4.10.1, 7.2.4, 7.4.6, 7.5.2, 7.6.3, 8.1.6, 9.4.5, 11.2.3, 11.2.4, 11.8.8, 12.4.10, 12.4.14, 12.5.8, 13.4.6, 14.4.3 and 14.9.4 of the standard for electrical design of civil buildings (gb51348-2019).
Articles 4.1.6, 4.5.2 (3), 5.1.4 and 5.3.2 (3) of technical code for lightning protection engineering of ancient buildings (gb51017-2014).
Article 3.2.2 above refers to substations in civil buildings, and article 3.2.3 above refers to substations not set in civil buildings.
Emergency power supply refers to fire protection in most specifications.
article 3.1.7, 4.1.7, 4.1.9, 4.1.10 and 4.10.1 of technical specification for laying mineral insulated cables jgj232-2011.
The common power supply is the mains power, and the standby power supply can be an independent power supply, generator and battery.
VII.
After “one-year preparation, three-year research and compilation, and two-year formulation”, comparison and research with domestic regulations and domestic and foreign standards, several changes of drafts, and many special demonstration meetings, the general specification for building electrification and intelligence was approved as a national standard.
III.
Articles 4.6.6 and 4.7.6 of the standard for design of intelligent buildings (gb50314-2015).
II.
Vi.
In combination with Article 4.1.4 sharing firewood and hair at the same time, I think we can understand that it is a four-stage power distribution system.
This specification is a mandatory engineering construction specification, and all provisions must be strictly implemented.
X.
In case of any inconsistency between the relevant provisions of the current engineering construction standards and this specification, the provisions of this specification shall prevail.
articles 3.1.5, 3.1.7, 6.1.1, 10.1.1, 11.1.1, 12.1.2, 13.1.1, 13.1.5, 14.1.1, 15.1.1, 18.1.1, 18.1.5, 19.1.1, 19.1.6, 20.1.3, 23.1.1 and 24.1.3 of code for acceptance of construction quality of electrical engineering of buildings gb50303-2015.
