The utility model comprises a box body, a transformer chamber, a high pressure chamber, a lower pressure chamber and an electric control component which are arranged in the box body, wherein, the transformer chamber, the high pressure chamber and the lower pressure chamber are integrated into integration by a baffle plate, a divided oil tank wall of the transformer chamber is the wall of the box body, and the external of the oil tank wall is provided with radiating fins; the main parts of the electric control component is soaked in the oil tank of the transformer chamber, and each adjusting end of the electric control component is respectively encapsulated in control panels of the high pressure chamber and the lower pressure chamber. The utility model has the advantages of compact structure, small size, convenient transportation and field arrangement, good heat dissipation condition and convenient maintenance, the utility model utilizes transformer oil to replace air to be used as an insulation medium so as to enhance the voltage output quality and enhance the running safety.
Description
The utility model relates to a kind of assembled electric equipment that is used to become the distribution field, the prefabricated substation of particularly a kind of simple installation, security of operation.
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 the high and low pressure electric elements are dielectric with the air, and safety and reliability are poor, and easy condensation, dust stratification dirt in the case 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 has been not easy to safeguard, again taking up space also is unfavorable for transportation and on-the-spot the setting more.Transformer is not easy heat radiation in fully sheathed case simultaneously, influences the voltage output quality, causes operation troubles easily.Therefore, have case now and become the demand that can not satisfy change distribution design in the net construction of current city, the transformation.
The purpose of this utility model provides a kind of 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.
The purpose of this utility model is to realize like this; This device comprises casing and assembles its interior transformer room, high and low pressure chamber and electric controling assembly, wherein transformer room and high and low pressure chamber utilize dividing plate integrated, the oil tank wall of the transformer room that is separated into is box body wall, and fin is set outside oil tank wall, high voltage load switch in the electric controling assembly, high-tension fuse, No-load changer shunting switch, the oil immersion of high and low pressure feed line terminals and are adjusted end with its each and are encapsulated in respectively on the control panel of high and low pressure chamber in oil tank of transformer.
Because the utility model adopts oil to add air gap constant volume principle and designs, cancel traditional conservator, in closed box, utilize dividing plate with transformer room and height, low-pressure chamber is integrated, with the oil tank wall of box body wall as the transformer room, make the negative switch of high pressure in the electric controling assembly, high-tension fuse, the No-load changer shunting switch, high, low pressure feed line terminals etc. is packaged in the fuel tank of transformer room, each is adjusted end and is encapsulated in height respectively with it, on the control panel of low-pressure chamber, so this device and similar case in a disguised form than, greatly saved height, the space of low-pressure chamber, structure is compact more, obviously reduced volume helps 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 improved the voltage output quality and strengthened property safe and reliable to operation.Therefore, the utility model is easy to apply.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model removal protection door leaf.
Fig. 2 is the vertical view of Fig. 1 removal casing top cover.
Fig. 3 is the end view of Fig. 1.
Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device comprises the closed box 1 that has hanger 11 and fuel outlet valve 2, utilize transformer room 15, low-pressure chamber 18, hyperbaric chamber 21 that dividing plate is separated into casing 1, be assembled in transformer device 17 in the casing 1, high and low pressure electric controling assembly etc.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, and 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 utilizes transformer oil to make dielectric in transformer room 15, this both can save the space of high and low pressure chamber greatly, can improve the reliability that each assembly uses again.The terminals of low pressure feed line terminals 12 have fixed support 13; concentrated being assembled in the low-pressure chamber such as oil level indicator 7, pressure gauge 8, pressure relief valve 9, oil thermometer 10 in addition; 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 is so that transportation and placement can be played the effect of beautifying the environment.In the operation and maintenance operation, open the protection door leaf 22 of casing 1, can operate, very convenient.
