Description
Technical field
The utility model relates to transformer station's technical field, is specially a kind of water-impervious box-type substation being applied to cable shaft.
Background technology
Box-type substation is widely used in urban construction, it comprises casing, transformer room door, transformer, the high voltage switch circuit being located at transformer front and back ends and low voltage switching circuit, in order to the power delivery that power plant is sent is to place far away, voltage must be raised, become high-tension electricity, on demand voltage is reduced again near user, the work of this buck/boost has come by transformer station, the capital equipment of transformer station is switch and transformer, different according to scale, become transformer station, electric substation, switchgear house etc.
Box-type substation is by high powered, transformer pressure-reducing, the functions such as low-voltage distribution organically combine, be arranged on a protection against the tide, antirust, dust-proof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, in moveable steel construction casing, but in some humid region, be arranged in outdoor cabinet type transformer station frost and dew of easily condensing, reduce security performance and the useful life of transformer station, particularly be applied to the box-type substation of outdoor cable well or underground cable well, when do bad of the water-impervious process of cable shaft itself or run into other reasons cause infiltration time, easily slow erosion is formed to the body structure of transformer station, transformer station is installed and occurs loosening, unstable, even occur concentrating and then penetrate into the situation that fault is caused in transformer station inside because of moisture, be therefore the specific demand of appropriate cable well, need badly and box-type substation of the prior art is improved.
Utility model content
The purpose of this utility model is to provide a kind of water-impervious box-type substation being applied to cable shaft, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
Be applied to a water-impervious box-type substation for cable shaft, comprise casing, be positioned at the base below casing and be positioned at the mushroom-shaped top cover above casing, mushroom-shaped top cover has the outstanding outer of annular; An annular slab coordinated with base lower surface is fixedly connected with in the lower surface of base, the lower surface of annular slab is fixedly connected with cast iron bearing plate, annular slab matches with base and bearing plate formation cavity, is provided with some projections spaced apart in the bottom of bearing plate; The side that base, annular slab and bearing plate are corresponding is set with a sheath; Described base hollow and surrounding offers the first ventilation hole with described cavity connects, casing is provided with the second ventilation hole, the 3rd ventilation hole is provided with at casing top, described first ventilation hole and described cavity form the first gas channel, second ventilation hole and described 3rd ventilation hole form the second gas channel, and the inner side of described first ventilation hole and the 3rd ventilation hole is provided with flow-guiding structure.
As the utility model further technical scheme, the lateral wall of sheath is the circular arc of outwardly convex.
As the utility model further technical scheme, the outside of described first ventilation hole is provided with netted lattice gear structure.
As the utility model further technical scheme, described second ventilation hole is the ventilation hole of shutter.
As the utility model further technical scheme, described flow-guiding structure is ventilating fan or air guide channel.
Compared with prior art, the utility model by arranging two gas channels one on the other in box-type substation, effectively prevent condensation, and pass through flow-guiding structure, improve ventilation effect, improve the security performance of transformer station, the multiple seepage-proof structure arranged in base lower end can pre-water-impervious well, improves the useful life of transformer station.
Accompanying drawing explanation
