CN201008079Y - Underground and overground combination ten kilovolt box type transformer station - Google Patents

Abstract

The utility model relates to an over ground and under ground combine ten thousand volt box type substation, which belongs to substation technical territory for electric supply to cities and suburbs and comprises an over ground part and an under ground part which are separated or combined with each other. The utility model is characterized in that the upper ground part is provided with two rooms in the shell which are a high voltage cabinet and a low voltage cabinet, the under ground part comprises cables and a transformer room, which means that the well know box type transformer is taken of out the transformer room and embedded in the underground cable room. Original transformer room is eliminated and original cable room is turned into cable and transformer room. Original three independent rooms (low voltage cabinet, high voltage cabinet and transformer room) in the box type shell turn into two independent rooms (high voltage cabinet and low voltage cabinet), which decreases volume of the box.

Description

Underground adding, made up ten kilovolts of box-type substations on the ground

Affiliated technical field

The utility model relates to a kind of ten kilovolts of box-type substations (becoming hereinafter to be referred as case), belongs to town and country power supply, distribution box-type substation technical field.

Background technology

Present known case becomes to be made up of this three big main body of ten kilovolts of high-tension switch cabinets, distribution transformer and low-tension switch cabinets, and they are installed in the big casing.Again because high-tension switch cabinet, distribution transformer and low-tension switch cabinet must isolate mutually, so this big casing again within it portion cut off into three independently chambers with steel plate, be hyperbaric chamber, transformer room and low-pressure chamber respectively.High-voltage board, transformer and low-voltage cabinet with copper bar, aluminium row or cable can not short circuit be connected successively after, just constitute a case and become.The case change is placed on ground level top, the underground brick mix structure basis that needs to build energy bearing box variable-weight under case becomes.In order to place the cable to the case variable power transmission, a basement shape will be made in its basis.Be also referred to as the cable vault.The wall of cable vault is the basis that case becomes just.So the planar dimension of cable vault planar dimension inevitable and that case becomes is close.And the cross section maximum that case becomes with ten kilovolts of high-tension cables is 95MM ², low-voltage cable is 240MM just ²To 25MM ²Between, not accounting for much volumes after more than the 20 cable proper alignment yet, large space still can utilize so the cable vault that present known case becomes has very.

Summary of the invention

In order further to utilize the space, cable vault, reduce case variable volume and floor space, the utility model provides a kind of small size case to become, and promptly underground adding, made up ten kilovolts of box-type substations on the ground.

The technical scheme that its technical problem that solves the utility model adopts is: this case becomes by partly buried to be formed with ground two parts, these two parts are separable capable of being combined, it is characterized in that: the enclosure interior of aerial part has two chambers, a high-voltage board chamber, a low-voltage cabinet chamber, the space of half buried part is cable, transformer room.Just the transformer that known case is become takes out from the transformer room, moves into the cable basement, original transformer room is taken down, and original cable vault has become cable, transformer room.Originally case becomes interior three separate chambers (high-voltage board chamber, transformer room, low-voltage cabinet chamber) of shell and becomes two separate chambers (high-voltage board chamber, low-voltage cabinet chamber), and equates with former chamber volume separately, has so just dwindled the volume that case becomes.

The beneficial effects of the utility model are: dwindled the volume that case becomes, reduced case and become floor space, reduced and made the material usage that case becomes, reduced manufacturing cost, improved the running environment that case becomes.

Description of drawings

Below in conjunction with accompanying drawing the utility model is illustrated

Fig. 1 is that the utility model case becomes profile

Fig. 2 is that known case becomes profile

Number in the figure: 1, transformer room, 2, the low-voltage cabinet chamber, 3, low-voltage cabinet, 4, cat ladder, 5, cable protection pipe, 6, cobble, 7, transformer, 8, the high-voltage board chamber, 9, high-voltage board, 10, the steel shutter, 11, the cable vault, 12, shell, 13, cable, transformer room.

Embodiment

The utility model can realize that the inherent condition that dwindles known case variable volume is: the cable vault that former known case becomes, also have living space and can utilize.The requirement of gene basis load-bearing object, basic plane size originally must conform to the wall size that case becomes, thereby cable vault's size and case turn indoor clean planar dimension and are more or less the same, only need very little a part of space and place cable, the transformer of putting into the cable vault just in time takies space very spacious originally but that waste, after the case variable volume dwindled, the basis diminished, and the cable vault is also corresponding to diminish.Add the planar dimension of low-voltage cabinet chamber planar dimension sum because of former case becomes the high-voltage board chamber greater than the transformer room, thus the cable vault after dwindling place transformer add cable still spaciousness have a surplus.

Embodiment is exactly: as shown in Figure 1, case becomes on the ground establishes two chambers (high-voltage board chamber 8, low-voltage cabinet chamber 2) in the shell 12, and had both placed cable and places transformer the cable vault.Be that cable vault 11 shown in Figure 2 has become cable shown in Figure 1, transformer room 13.The remainder that known case becomes does not change.Become the same with former known case, four sides, basis outer wall will be used the antiseepage cement plaster, to prevent infiltration.For preventing water logging cable, transformer room, foot wall will exceed 600 millimeters to 1000 millimeters of ground levels.And the case change is not installed in low-lying ponding zone.Above ground level 300 millimeters with top, each one side of ventilation shutter of 300 millimeters high 1000 mm wides is installed on the foot wall of four sides, give cable, ventilation of transformer room heat radiation.Become in the shell because of main thermal source transformer shifts out case, thereby the temperature rise that case becomes in the shell reduces, ventilation and heat requires to reduce, and can reduce the ventilation hole that case becomes shell, has also just reduced entering of dust, and high and low voltage switch is to be afraid of very much dust.The shared shell in high-voltage board chamber, the low-voltage cabinet chamber that the utility model case becomes and cable, transformer room are combinations independently separately, can separate very easily when needing and make up.Its combination becomes identical with the combination and the separate mode of cable vault with separate mode and former known case.The utility model is the type that ten kilovolts of casees become, and just a kind of space layout that former known case is become is improved, thereby technology is changed seldom.

Claims (1)
