Electric construction is common problem
From;    Author:Stand originally
One, violate compulsive standard and normative aspect
1. power source enters a place to should be done always equipotential coupling. Disobey: " low-pressure distribution designs a standard " GB50054 - 95 the 4.4.4th. Processing: Fill a sketch map, increase always equipotential the practice of coupling explains.   
Box of 2. motivation distribution should iterative earth, increase put oneself in another's position of dozen of artificial ground connection, or use device of fundamental ground connection, its receive terrestrial electricity block to should achieve GB to ask. Disobey: " the ground connection of industry and civil power plant designs a standard " GBJ65 - 83 the 3.0.1st. Processing: Fill with Change Notice means the iterative earth that makes a total case.   
Lv of 3. building take an examination defends measure of thunder ground connection, if do not need fortify Lei Shi, should provide perfect design basis. Disobey: " the building prevents thunder to design a standard " GB50057 - 94  2000 the 2.0.4th the 4th. Processing: Provide complete enumerated data, keep original design, do not install the measure that prevent thunder. Analysis: If Xiamen is such-and-such,wide × of building long × is 6.9m of × of 32.4m × 12m high, light to be not taste storeroom. According to formula of design manual P677, building year  of N=KNgAe of frequency of predicting be struck by lightning second / A.  of classics computation N=0.042 second / Alt;0.06  second / A, reason does not belong to the 3rd kind of building that prevent thunder. GB50057 - the 2.0.4th 94 the 4th section provision " frequency of predicting be struck by lightning is more than or be equal to 0.06 times / the run-of-mill industry structure of A " should delimit prevent Lei Jianzhu thing for the 3rd kind.   
4. double power source was not adopted prevent to stand side by side the measure that run. Disobey  " design a standard for distribution system " GB50052 - 95 the 3.0.2nd. Processing: 1 design of  chooses a ground GB atlas " circuit of switch of low-pressure double power source pursues " the case of switch of standard double power source that 99D373 makes, already took closedown device to move with preventing double power source to stand side by side oneself.  2 closedown mark is added on systematic graph or explain. 5. The structure with 2 kinds of more than 45 meters high demands that prevent thunder is due defend by-blow thunder measure. Disobey  " the building prevents thunder to design a standard " GB50057 - 94  2000 the 3.3.10th. Processing: The 3.3.10 clause of detailed of practice specification  that defend by-blow thunder raise on the graph that prevent thunder.   
Power source of 5 220/380V exterior line should make clear 6. which a few cannot from change electric place is same and low-pressure mother line segment is derivative, in order to make sure two each other cast the dependability of power source. Disobey: " design a standard for distribution system " GB50052 - 95 the 2.0.2nd. Processing: Introduce power source line number, add a specification to ask which a few cannot be brought from line segment of same and low-pressure mother.
