Abstract: At the conclusion of design experience， combined in civil construction in the electrical design issues frequently encountered by the paper on the main hospital building in the electrical design of the following questions: 1， through different forms of wiring fault occurred when the current flowing through the human body， discussed the use of the operating room for patients isolated power system provides a reliable security The isolation and detailed description of the composition of power supply system 2， a more detailed exposition of the various functional integrated ward floor area electrical design 3， by the nature of lightning current， lightning current distribution， in line with the state of existing norms mine classification of the building from the proposed mine measures four aspects are the main anti-lightning directly stroke， mine electric sensors， mine waves penetrated and anti-magnetic pulse 4， in order to effectively reduce human exposure voltage， and can effectively eliminate foreign economic relations since the building of electrical lines and metal pipes into buildings dangerous fault voltage hazards， such as potential connection to further protect the buildings used electrical
The graduation to the design plan， based on the principle of national economic development， policies， technical requirements criteria， combined with the actual construction to ensure reliable power supply， scheduling flexibility to meet the technical In the analysis of raw data based on the 110KV substation electrical design engineering on several comparative analysis of the connection modes of operation， first elected to meet the 110KV substation safe， reliable quality， following the security requirements of economic operation and the best connection mode as normal 110KV substation run main electrical On the development of the main electrical connection， to short-circuit current calculation， to choose a reasonable electrical Finally， a part of the wiring and the configuration of relay protection requirements to ensure safe and economic operation of the substation to prevent the occurrence or expansion， to the purpose of safe and economic Substation automation is the secondary substation equipment (including measuring instruments， signal systems， relay protection， automatic devices and remote devices， ) through a combination of functions and optimize the design， use of advanced computer technology， modern electronic technology， communication technology and signal processing technology， on all major substation equipment and transmission and distribution lines of automatic monitoring， measurement， automatic control and computer protection， and integrated communications and scheduling automation
