Abstract

The utility model relates to an outdoor combination-type transformer substation, which comprises a box body and a transformer room, a high-voltage room, a low-voltage room and an electric control component, which are assembled inside the box body, and is characterized in that the transformer room is integrated with the high- and the low-voltage rooms through a separation plate, and the divided oilbox wall of the transformer room is the wall of the box body, heat radiation sheets are arranged outside the oil box wall, and a high-voltage load switch, a high-voltage fuse plug, a load-free voltage-regulation tapping switch and a high-voltage and a low-voltage feeder line terminators are immersed in the oil inside the transformer oil box, and all adjusting ends are respectively encapsulated ona control panel of the high- and the low-voltage rooms. The transformer room is integrated with the high-voltage room and the low-voltage room through the separation plates inside the closed box body, and the wall of the box body is used as the wall of an oil box of the transformer room, so that the high-voltage load switch, the high-voltage fuse plug, the load-free voltage-regulation tapping switch and the high-voltage and the low-voltage feeder line terminators are encapsulated inside the oil box of the transformer room, and all adjusting ends are respectively encapsulated on the control panels of the high-voltage and the low-voltage rooms.

Description

A kind of outdoor prefabricated substation

Technical field:

The utility model relates to and a kind of high-voltage electrical equipment, transformer, low voltage equipment etc. is combined into the complete power distribution equipment of compact, particularly relates to a kind of outdoor prefabricated substation.

Background technology:

Along with development of electric power industry, become the assembled electric equipment prefabricated substation in distribution field, also claim box-type substation, be called for short case and become, become in net construction of current city and the urban network restructuring planning, the preferential change distribution design of selecting, but, existing case change generally is simply and will concentrates in the metal box of a sealing after the conventional electrical appliance assembling, promptly comprises three parts that are provided with respectively separately in the case, i.e. transformer room, hyperbaric chamber, low-pressure chamber.After each parts apportion independently is provided with, piece together in a metal enclosed case, wherein high, low voltage component is dielectric with the air, safety and reliability are poor, easy condensation in the case, dust stratification dirt, cause case accident barrier easily, influence its serviceability and useful life, increase maintenance workload, in addition above-mentioned three separate chambers are loaded on respectively in the metal cabinet, overall volume is big, both be not easy to safeguard, again taking up space also is unfavorable for transportation and on-the-spot the setting more, and transformer is not easy heat radiation in fully sheathed case simultaneously, influence the voltage output quality, cause operation troubles easily, therefore, existing case becomes can not satisfy the net construction of current city, become the demand of distribution design in the transformation.

Summary of the invention:

The purpose of this utility model provides a kind of outdoor prefabricated substation, its compact conformation, and volume is little, help transportation and on-the-spot the setting, its radiating condition is good, and is easy to maintenance, replace air to make dielectric with transformer oil, improve the voltage output quality, strengthen property safe and reliable to operation.

Order of the present utility model is realized by following technical proposals:

A kind of outdoor prefabricated substation; comprise the closed box that has hanger and fuel outlet valve; the transformer that utilizes dividing plate that casing is separated into; low-pressure chamber; the hyperbaric chamber; be assembled in the transformer device in the casing; high; the low-voltage electrical control assembly; it is characterized in that: wherein casing is by the protection door leaf of hinge mounting strap jug and lockset; the casing rear portion is divided into the fuel tank of transformer room; its oil tank wall is box body wall; for further improving the heat dispersion that this case becomes; many group fin are set outside oil tank wall; the casing front portion is divided into hyperbaric chamber and low-pressure chamber; the adjustment end joystick or the knob of electric controling assembly; be encapsulated in respectively on the control panel separately; high voltage load switch in each assembly; high-tension fuse; the No-load changer shunting switch; the high pressure feed line terminals; all oil immersion is in the transformer room; utilize transformer oil to make dielectric; this both can save height greatly; the space of low-pressure chamber; can improve the reliability that each assembly uses again; the terminals of low pressure feed line terminals have fixed support; oil level indicator in addition; pressure gauge; pressure relief valve; oil thermometer is concentrated and is assembled in the low-pressure chamber; also saved the space of low-pressure chamber, the backup protection fuse is loaded in the fuel tank of transformer room.

The usefulness of a kind of outdoor prefabricated substation of the utility model is:

This device and similar case in a disguised form than, greatly saved the space of high and low pressure chamber, structure is compact more, obvious reduced volume, help transportation and field apparatus, simultaneously, because of the major control assembly all is immersed in the transformer oil, with box body wall as the oil tank wall of transformer room and outside it, set up fin, so significantly improve the serviceability of radiating condition and electric component, replace air to make dielectric with transformer oil, also improve the voltage output quality and strengthened property safe and reliable to operation, therefore, the utility model is easy to apply.

Embodiment:

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

At Fig. 1; Fig. 2; among Fig. 3; a kind of outdoor prefabricated substation; comprise the closed box 1 that has hanger 11 and fuel outlet valve 2; the transformer 15 that utilizes dividing plate that casing 1 is separated into; low-pressure chamber 18; hyperbaric chamber 21; be assembled in the transformer device 17 in the casing 1; it is characterized in that: wherein casing 1 is by the protection door leaf 22 of hinge mounting strap jug 19 and lockset 20; casing 1 rear portion is divided into the fuel tank of transformer room 15; its oil tank wall is box body wall; for further improving the heat dispersion that this case becomes; many group fin 14 are set outside oil tank wall; casing 1 front portion is divided into hyperbaric chamber 21 and low-pressure chamber 18; the adjustment end of each electric controling assembly; as joystick or knob etc.; be encapsulated in respectively on the control panel separately; high voltage load switch 4 in each assembly; high-tension fuse 5; No-load changer shunting switch 6; high pressure feed line terminals 3; low pressure feed line terminals 12; all oil immersion is in transformer room 15; utilize transformer oil to make dielectric; this both can save height greatly; the space of low-pressure chamber; can improve the reliability that each assembly uses again; the terminals of low pressure feed line terminals 12 have fixed support 13; oil level indicator 7 in addition; pressure gauge 8; pressure relief valve 9; concentrated being assembled in the low-pressure chamber such as oil thermometer 10 grades; also saved the space of low-pressure chamber, backup protection fuse 16 is loaded in the fuel tank of transformer room 15.

Owing to this device is littler than the volume that similar case becomes, institute in the operation and maintenance operation, opens the protection door leaf 22 of casing 1 so that transportation and placement can be played the effect of beautifying the environment, and can operate, and is very convenient.
