Yueyang South Lake Hotel Lightning Protection And Grounding Transformation Project Case
Building lightning protection is the field of lightning protection in the closest to life,lightning rods everywhere on the roof,crenelated parapet wall of the lightning belt,household circuit in the lead wire,all belong to this scope.
In many buildings,hotels because of its dense,complex functions,advanced equipment and other characteristics,the implementation of lightning protection measures can best reflect the comprehensive,but also best reflect the level of lightning protection design and construction.Lightning protection for hotels is not only about the safety of the building itself,but also involves the life safety of guests and employees,as well as the continuity of hotel operations.Therefore,a comprehensive lightning protection system design for the hotel is crucial.
Reasonable hotel lightning protection measures,not only to consider the hotel's geographic environment,climatic conditions,structural characteristics and the distribution of internal electrical and electronic systems,but also according to the‘Lightning Protection Design Code for Buildings’(GB50057-2010),combined with the classification of the building's lightning protection,the organic combination of external lightning protection and internal lightning protection.External lightning protection devices include flashover,lead wires and grounding devices,while internal lightning protection devices involve equipotential connections,electromagnetic shielding,surge protection and so on.
The following is a typical case of OUMAAN-HENGDIAN lightning protection in the hotel rectification.
South Lake Hotel is located in the beautiful scenery of the South Lake shore,the International Dragon Boat Race West Grandstand.This is an ecological garden building located in the forest on the lake:three sides of the water,island style,surrounded by green trees,a quiet environment.
Four seasons of flowers and grasses fragrant,rare birds gather,known as‘Yueyang State Guesthouse’beauty of the name.It is a four-star hotel managed by the reception office of the Party committee and the municipal government of Yueyang City,and is the window and reception centre of Yueyang City opening to the outside world.Because of the reception of foreign guests,the security has high requirements.The hotel is surrounded by wide waters,which are easy to be the target of lightning strikes during thunderstorms.
Internal rectification measures:
In order to improve the lightning protection ability of the hotel building,to ensure the safety of building facilities and personnel,Oumaan Technology Group-Heilongjiang Hengdian Lightning Protection Engineering Co.,Ltd.implemented lightning protection and grounding renovation project for South Lake Hotel.
The transformation at the same time to take a number of lightning protection measures.Firstly,the original lightning protection system in the hotel was comprehensively checked and upgraded.Installation of equipotential connection device in the machine room ensures the potential balance between the various parts of the building and avoids the discharge caused by potential difference.
Secondly,surge protection devices were also added to the power side of the lines.It realises graded protection,rapidly absorbs the overvoltage and overcurrent generated by lightning and introduces them into the ground,thus protecting the hotel's power supply system,communication equipment and other key facilities from lightning.
Grounding rectification measures:
Finally,we adopted flexible grounding technology for the grounding device to increase the contact area between the metal grounding electrode and the earth,which not only reduces the grounding resistance,but also effectively enhances the ability of the grounding network to withstand the impact of high-frequency lightning current,and guarantees the normal operation of equipment such as the flashover and surge protection devices.
Oumaan Technology Group-Heilongjiang Hengdian Lightning Protection Engineering Co.,Ltd.has been committed to the research of lightning protection and grounding technology for many years,and has carried out a large number of lightning protection and grounding renovation projects in electric power systems and new energy generation stations all over the country,and has achieved fruitful results.
We have our own team of experts,construction teams and production bases,specialising in solving all kinds of lightning protection related problems,including but not limited to:high grounding resistance,transmission line lightning tripping,sustained lightning strikes burned equipment,poor corrosion of the environment is serious,wet and dirty insulation flashover,the cause of the accident is difficult to investigate......
As long as the lightning protection related services,Oumaan Technology Group can provide.Want to get more related content,welcome to call the hotline to learn more!
