The safety of the outdoor prefabricated substation provided by the utility model is high, operators cannot easily get electric shocks during tour inspection and observation, potential safety hazards are reduced, and the outdoor prefabricated substation is convenient and safe to operate.
Description
Technical field
The utility model relates to a kind of transformer station, is specifically related to a kind of outdoor preassembled transformer station of convenient and safe operation.
Background technology
Along with Chinese economic development and quickening of urbanization process, load density is increasingly high, urban land is more and more nervous, progressively by the appearance of overhead wire to new situations such as cable transition, bigger variation has also taken place the urban electricity supply general layout urban power distribution network.The sort of concentrated step-down of past, long mode apart from distribution are because radius of electricity supply is big; Line loss increases with the increase of power load greatly, and the circuit corridor is more and more nervous, and power supply quality also reduces greatly simultaneously; Restrict the power supply in city thus, and reduced the benefit of electric company.As to reduce line loss, and guarantee power supply quality, must improve supply power voltage, high pressure directly gets into the urban district, gos deep into load center, forms the power supply general layout of " high powered--transformer step-down---low-voltage distribution ".Simultaneously in order to adapt to the development of urban power distribution network, satisfy the requirement that urban planning occupies environment and soil, the effect of preassembled transformer station in the net of city is more and more important, uses also more and more widely.
So-called preassembled transformer station; Be meant and a kind of high voltage switchgear, distribution transformer, low-voltage distribution equipment and other servicing units formed the complete power distribution equipment of prefabricate close-coupled of one by certain connection plan, be about to the power distribution equipment that functions such as high powered, transformer step-down, low-voltage distribution organically combine.Because its complete property is strong, volume is little, occupation of land is few, thus can go deep into load center, thus improved power supply quality effectively, reduce the wastage; Have again simultaneously addressing flexibly, to advantages such as environment damage property are little, easy for installation, safe and reliable to operation.
Present preassembled transformer station is widely used in the resident and builds in dwelling house and the industrial and mining enterprises; In traditional preassembled transformer station structure, comprise high pressure incoming line cabinet, tranformer protection cabinet and high-voltage terminal cabinet, owing to influenced by overall space; High-pressure installation in high pressure incoming line cabinet, tranformer protection cabinet and the high-voltage terminal cabinet can change accordingly; Especially people need open the cabinet door constantly and patrol, and charged parts are directly exposed in face of the operating personnel when opening the cabinet door, and are within reach; Be very easy to cause danger inconvenient user's safety operation.
The utility model content
The technical problem that the utility model solved is to provide a kind of outdoor preassembled transformer station of convenient and safe operation, and it has reduced potential safety hazard, has improved fail safe, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of outdoor preassembled transformer station of convenient and safe operation; Comprise the preassembled transformer station body; Said preassembled transformer station body comprises inner high pressure incoming line cabinet, tranformer protection cabinet and the high-voltage terminal cabinet of installing side by side in regular turn; Be with the remarkable difference of traditional structure preassembled transformer station, on the cabinet of said high pressure incoming line cabinet and high-voltage terminal cabinet poly (methyl methacrylate) plate be installed, said tranformer protection cabinet inside is equipped with the insulation board that is used for the high-voltage switch gear upper isolation of inside.
As a kind of improvement, on the said high pressure incoming line cabinet electrification display is installed.Electrification display is a kind of indicative safety device whether electric equipment has working voltage that intuitively demonstrates, and when equipment had working voltage, this display display window flashed, and caution people high-tension apparatus is charged, does not then have indication when not having electricity.
In order further to improve the fail safe of operation, the cabinet door of said tranformer protection cabinet is provided with the mechanical latching of realizing interlocking with the internal high pressure switch, and has the lock release device on the cabinet door of tranformer protection cabinet.When high-voltage switch gear closed a floodgate, this mechanical latching was not opened, and in emergency circumstances can utilize the lock release device with cabinet door enforced opening.
The outdoor preassembled transformer station that the utility model provides; On the cabinet of high pressure incoming line cabinet and high-voltage terminal cabinet, poly (methyl methacrylate) plate is installed; When the cabinet door is opened; Operating personnel can observe, make an inspection tour inner parts, but charged parts are not directly exposed in face of the operating personnel, can not touch these live parts under operating personnel's normal condition; And insulation board is installed in tranformer protection cabinet inside, and this insulation board makes inner high-voltage switch gear upper isolation, the bottom becomes separate space, has so just increased operating personnel's safe space.
In addition, on the high pressure incoming line cabinet electrification display is installed, can intuitively demonstrates preassembled transformer station and whether have working voltage, further improved fail safe.
Owing to adopted above structure, the utlity model has following beneficial effect:
The outdoor preassembled transformer station that the utility model provides, safe, operating personnel are making an inspection tour, are being not easy to take place Danger Electric shock risk when observing, and have reduced the potential safety hazard that exists, convenient and safe operation.
