Abstract
The utility model discloses a box-type substation, which has good radiating conditions and low load loss, and can be used with no derating. In the technical scheme, a transformer is arranged between a low-voltage chamber and a high-voltage chamber, a high- and low-voltage incoming/outgoing wire enclosing cover is arranged on the transformer and is connected with the low-voltage chamber and the high-voltage chamber, and a radiator of the transformer is exposed to the atmosphere, thereby realizing good radiating conditions and ensuring that the transformer can bear high loading rates. The utility model can be applied in the outdoor box-type substation with the oil-immersed transformer in the power transmission and distribution system, and can also be used in other electrical boxes with the high radiating performance.
Description
Technical field
The utility model relates to the technical field of box-type substation.
Background technology
The box-type substation that moves at present in China's electrical network has two classes: American box-type substation and European box-type substation.American box-type substation is combined in high pressure components and parts such as high voltage load switch, plug-in fuse, reserve current-limiting fuse, transformer itself, off circuit tap changer in the fuel tank of sealing, by transformer oil or high burning-point dielectric as dielectric, therefore simple in structure, size can greatly reduce, but, can't set up the power distribution automation device because of no motor drive mechanism; The capacitorless device, unfavorable to reducing line loss; Because all in fuel tank, maintenance is inconvenient for components and parts.European box-type substation has following shortcoming: oil-filled transformer is positioned in the casing, has worsened the radiating condition of transformer, causes the transformer operating temperature to raise, and causes transformer load loss to be risen significantly, and reduce useful life significantly, and load factor also reduces.
Summary of the invention
The purpose of this utility model provides the efficient box-type substation that a kind of radiating condition is good, load loss is little, load factor is high.
The technical solution of the utility model: a kind of efficient box-type substation, comprise hyperbaric chamber, low-pressure chamber, transformer, high-low pressure turnover line enclosed hood, it is characterized in that: transformer is positioned between hyperbaric chamber and the low-pressure chamber, transformer is connected with equipment in hyperbaric chamber, the low-pressure chamber by high-low pressure turnover line enclosed hood, and the radiator of transformer is connected with ambient atmosphere.
In described hyperbaric chamber and the end face between the low-pressure chamber sunshading board is installed.
Guard rail or protection network are installed in side between described hyperbaric chamber, low-pressure chamber.
Compared with prior art, the utility model box-type substation, the conventional oil-filled transformer of transformer adopting, transformer is connected with equipment in hyperbaric chamber, the low-pressure chamber by the busbar in the high-low pressure turnover line enclosed hood or cable.High-low pressure turnover line enclosed hood can be made integral body or split, the radiator of transformer is connected with ambient atmosphere, the radiator that is about to transformer places ambient atmosphere, heat and ambient atmosphere that transformer produces directly exchange, improved the efficient of heat radiation, load loss is little, and load factor also is improved simultaneously.End face between hyperbaric chamber, the low-pressure chamber is preferably installed sunshading board, avoids the sun transformer that is exposed to the sun, and guard rail or protection network are preferably installed in the side between hyperbaric chamber, the low-pressure chamber, prevents that animal or child from damaging.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Wherein: 1, hyperbaric chamber, 2, low-pressure chamber, 3, transformer, 4, radiator, 5, high-low pressure turnover line enclosed hood, 6, high pressure inlet wire cable, 7, low pressure outlet copper bar, 8, guard rail or protection network.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to utility model:
As shown in Figure 1, the utility model comprises hyperbaric chamber 1, low-pressure chamber 2, transformer 3, high-low pressure turnover line enclosed hood 5, transformer 3 is positioned between hyperbaric chamber 1, the low-pressure chamber 2, transformer is connected by high-low pressure turnover line enclosed hood 5 and hyperbaric chamber 1, low-pressure chamber 2 interior equipment, and the radiator 4 of transformer 3 is directly exposed in the atmosphere.
The conventional oil-filled transformer of transformer adopting, transformer is connected with equipment in hyperbaric chamber, the low-pressure chamber by the busbar in the high-low pressure turnover line enclosed hood or cable.High-low pressure turnover line enclosed hood can be made integral body or split, end face between hyperbaric chamber, the low-pressure chamber is preferably installed sunshading board, avoid the sun transformer that is exposed to the sun, guard rail or protection network are preferably installed in the side between hyperbaric chamber, the low-pressure chamber, prevent that animal or child from damaging.
