Description
Technical field
This utility model relates to underground substation technical field, the building structure of a kind of underground substation.
Background technology
For combining non-residential estate face, underground substation building, due to above ground structure transformer station located underground just
Top, the pipeline such as running water pipe in above ground structure, fire extinguisher canvas hose usually links together, and cannot accomplish real
Isolation, even if pipeline is cut off by insulant, the water in pipeline the most at all cannot accomplish insulation cut off.Meanwhile,
The ground connection of building connects using stake as earthing pole generally by the bar-mat reinforcement in floor, in shear wall and the bar-mat reinforcement in stake
Carry out ground connection, the most all outer layer stake meeting band steels or reinforcing bar and reinforcing bar in post be attached as grounded screen around a circle,
Have electrical equipment in skyscraper and building also can beat some artificial earthing poles, and the bare metal in building is carried out
Equipotential bonding.
But the short circuit current being positioned at lower transformer station is the biggest, more than tens of kilo-amperes, instantaneous touch voltage can be quite big,
If if now in building personnel contact simultaneously metal object that running water pipe is connected equal to underground substation grounded screen and with ground
The metal object that face building grounded screen connects is it is possible to there is Danger Electric shock risk, and human life can be on the hazard safely.It is therefore desirable to
The when of considering, in underground substation, electric short circuit occurs, on the impact of personal security in above ground structure.
Utility model content
The purpose of this utility model is to provide the building structure of a kind of underground substation, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, this utility model following technical scheme of offer: the building structure of a kind of underground substation, bag
Include: bar-mat reinforcement in surface structures pile foundation, the big top board in underground substation, underground substation main grounding grid, surface structures grounded screen,
Building artificial earthing pole, face and copper stranded conductor, reinforcing bar and bar-mat reinforcement weldering in the big top board in underground substation in described surface structures pile foundation
Connecing, in the described big top board of underground substation main grounding grid transformer station located underground above bar-mat reinforcement, described surface structures connects
Above earth mat transformer station located underground main grounding grid, and surface structures grounded screen passes through copper stranded conductor with underground substation main grounding grid
Connecting, the earth is inserted in described surface structures artificial earthing pole, and copper stranded conductor is passed through respectively at ground in surface structures artificial earthing pole
Bar connecting in lower transformer station main grounding grid, surface structures pile foundation.
Further, draw no less than 2 main reinforcements in above ground structure pile foundation.
Further, described copper stranded conductor specification is 120mm2。
Further, the junction point of described above ground structure artificial earthing pole and underground substation main grounding grid is in underground
It is uniformly distributed on transformer station's main grounding grid, and two ground Buildings of Artificial earthing pole maximum spacings are less than 12m.
The beneficial effects of the utility model:
Reinforcing bar riveting in the stake of above ground structure is entered the bar-mat reinforcement in the big top board in underground substation by this utility model, simultaneously
Face building grounded screen and underground substation grounded screen are reliably connected, above ground structure artificial earth electrode and substation grounding
Net is reliably connected, and requires that the building main reinforcement net of transformer station to be connected with System in Substation, and whole above and below ground is built
Constitute a faraday cup.Thus the when of eliminating underground substation generation electric short circuit, to personal security in above ground structure
Impact.
This utility model has the advantages such as simple in construction, reasonable in design, safe and effective and use easy to spread.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is made furtherly
Bright, to be fully understood from the purpose of this utility model, feature and effect.
