Description
Technical field
The utility model belongs to a kind of compact preassembled transformer station of 6～35kV level.
Background technology
Preassembled transformer station comprises box-type substation (European case change) and combined transformer (American case change).Box-type substation is made up of high voltage switchgear, transformer and low voltage switchgear.In the present box-type substation of China, the high voltage switchgear of employing has usually: produce (pressure) gas formula loading switch cabinet, vacuum loading switch cabinet, SF6 loading switch cabinet and SF6 ring net load switch cabinet (RM6 cabinet).Low voltage switchgear and transformer also all are to be mounted to separate unit respectively, again high voltage load switch cabinet B, transformer E, low-tension switch cabinet F are contained in the shell A, high voltage load switch cabinet B is connected with transformer E with bushing D by bonding conductor C, low-tension switch cabinet F also is connected as shown in Figure 1 by electric conducting material with transformer E.The weak point at box-type transformation station is: 1, volume is bigger, because high voltage load switch cabinet, transformer, low-tension switch cabinet in the box-type substation all are to manufacture and design respectively, each piece volumes is bigger, and all leaves bigger gap between each parts, therefore makes its overall volume bigger; 2, manufacturing cost is higher, because volume is big, connection lead and element between each parts are more, make the cost of box-type substation higher.Combined transformer is made up of high voltage load switch, transformer and low voltage switchgear.With the difference of box-type substation be: transformer d is contained in and forms " product " font layout on the hyperbaric chamber a that is arranged side by side and the low-pressure chamber f sidewall, high voltage load switch c is installed in the transformer d fuel tank, also having a kind of is that transformer d fuel tank is separated into two parts, part dress transformer d body, another part is adorned high voltage load switch c and is met the casing seat b that high-tension cable is used, the low pressure extraction tube e of transformer d stretches in the low-pressure chamber f, and the fin g of transformer d exposes, as shown in Figure 2.Combined transformer is littler than the volume of box-type substation, but in use also has the following disadvantages: 1, cable and less elements are only arranged in the hyperbaric chamber, and the space utilization in the hyperbaric chamber is insufficient; 2, because low-pressure chamber is heavier, and the hyperbaric chamber is lighter, and four hooks are arranged on the oil tank of transformer top, can produce inclination during lifting, and lifting is inconvenient; 3, the fin of transformer exposes, and during the transformer operation, temperature is higher, and combined transformer is installed in the urban road next door, and the fin of higher temperature may damage the pedestrian; 4, the low pressure of combined transformer is drawn conducting rod and is stretched in the low-pressure chamber, has taken the space of low-pressure chamber, makes the area of low-pressure chamber increase; 5, shared fuel tank of transformer body and high voltage load switch or the shared case lid of branch mailbox, the used dielectric of high-voltage switch gear just can only adopt the insulation wet goods liquid medium identical with transformer.
Summary of the invention
The purpose of this utility model provides that a kind of volume is less, cost is lower, lifting is convenient, the compact preassembled transformer station of safety relatively again.
The purpose of utility model is to realize like this, it is made up of cased high voltage load switch case, transformer and low-tension switch cabinet, one side wall surface of described high voltage load switch case is installed near a side wall surface of the oil box of transformer, and the electric conductor of transmission of electric energy is installed on the close mutually sidewall of the oil box of high voltage load switch case and transformer; Dielectric in one end of the electric conductor of transmission of electric energy and the high voltage load switch case contact, and the interior dielectric of the other end of the electric conductor of transmission of electric energy and the fuel tank of transformer contacts; The casing seat of adorning on the high voltage load switch case that connects cable is the inside that is positioned at the projection of high voltage load switch box body horizontal cross-section on the shell bottom surface that the high voltage load switch place is installed in the projection on the housing bottom surface; The casing seat that connects cable is installed on the casing of box top bottom of high voltage load switch case.
The utility model reduces machine volume because the topology layout compact and reasonable had both been saved the space, reduces cost, and can make the distribution of weight equilibrium of complete machine again, bring convenience to slinging work, and good looking appearance, compare safety again.
