Description

Small combined transformer station

The utility model relates to a kind of transformer station, particularly a kind of small combined transformer station, and it belongs to complete power distribution equipment, is applicable to that mainly floor space is less than six square metres occasion.

The prefabricated substation that present China develops voluntarily mainly contains two kinds of structures, a kind of is the monolithic devices combining structure, another kind is the separation type combining structure, the transformer station of these two kinds of structures all is made up of low-voltage distribution chamber, transformer room and high voltage power distribution chamber, just three Room of separation type can separate, transport more convenient and not seal its transformer thermal diffusivity better in the transformer room, but there is following shortcoming jointly in the transformer station of these two kinds of structures: 1, floor space is bigger, all more than six square metres, maximum reaches 12 square metres; 2, copper (aluminium) busbar in the low-voltage distribution chamber does not insulate, and easily jeopardizes operating personnel's personal safety and causes electric accident.In recent years China has introduced a kind of box-type substation from the U.S., its structure such as Fig. 1, shown in Figure 2, it mainly by transformer 1 ' and power distribution station cell I ' form, transformer 1 ' fixing with power distribution station cell I ', comprise among the power distribution station cell I ' high-tension fuse 2 ', high pressure end of incoming cables 3 ', pasta table 4 ', pressure relief valve 5 ', Pressure gauge 6 and low pressure leading-out terminal 10 ', also need install during use copper (aluminium) busbar 7 ', 8 ' and air circuit 9 ', although transformer station's volume of this structure is less, but still have the following disadvantages in using: 1. the power distribution station cell combines high pressure inlet wire and low pressure outlet, though reduced whole floor space, but owing to there is not metering device, indicating device and Electric capacity compensation device, and there is not an installation site, match so also need add a case in addition when using, give and install, use, maintenance has brought many inconvenience; 2. the low pressure leading-out terminal is not made insulation processing with being connected of copper (aluminium) busbar, and this jeopardizes operating personnel's personal safety, and causes electric accident easily.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, the little and installation of floor space, small combined transformer station easy to use.

The purpose that the utility model proposed can be achieved through the following technical solutions: this small combined transformer station comprises transformer and low-voltage distribution chamber, transformer and low-voltage distribution chamber integrator, at indoor pasta table, pressure relief valve, Pressure gauge, copper (aluminium) busbar, air circuit and the low pressure leading-out terminal of being equipped with of low-voltage distribution, its design feature is at indoor metering device, indicating device and the Electric capacity compensation device of also being equipped with of low-voltage distribution, and being provided with the high voltage power distribution chamber, this high voltage power distribution chamber links to each other with transformer.

Copper of the present utility model (aluminium) busbar is coated with isolating shrinkable tube, and the junction is covered with the isolating shrinkable joint, has prevented contingent casualty accident of operating personnel and electric accident thus.

The utility model compared with prior art has the following advantages and effect: 1. reasonable in design, do not establish the transformer room, and with transformer and low-voltage distribution chamber integrator, reduced volume, whole floor space is less than six square metres; 2. metering, indicating device and Electric capacity compensation device are arranged, be fit to China's national situation, be convenient to install and use; 3. copper (aluminium) busbar is coated with isolating shrinkable tube, has both guaranteed power supply safety and personal safety, has dwindled the distance between the energized conductor again.

Description of drawings is as follows;

Fig. 7 for this product with novel electrical block and syndeton schematic diagram (when master switch is housed).

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 3, the utility model is made up of transformer 1, low-voltage distribution chamber II and high voltage power distribution chamber III, transformer 1 and low-voltage distribution chamber II integrator, and the formation transformation is low joins the chamber, and high voltage power distribution chamber III then links to each other with transformer 1.

Referring to Fig. 4, Fig. 5, Fig. 6, low-voltage distribution of the present utility model chamber II is two-door box switchgear house, pasta table 4, pressure relief valve 5, Pressure gauge 6, copper (aluminium) busbar 7,8 air circuits 9, low pressure leading-out terminal 10, master switch 11, metering device 12, indicating device 13 and Electric capacity compensation device 14 are installed in the II of low-voltage distribution chamber, copper (aluminium) busbar 7,8 is coated with isolating shrinkable tube 15, the insulation that is connected between copper (aluminium) busbar 7,8 and other parts is connected, simultaneously, the connecting bolt 16 outer pyrocondensation insulating joints 17 that are surrounded by; When master switch 11 is loaded onto, when user side occurs with electric fault or has an accident, can operate master switch 11 cutoff low power supplys; It is also passable not adorn master switch 11, will stop the high-pressure side power supply when just breaking down.

Referring to Fig. 7, when dress master switch 11, high voltage power distribution chamber III links to each other with transformer 1 by insulated cable, transformer 1 is formed the low chamber of joining of transformation with low-voltage distribution chamber II integrator, draw low pressure leading-out terminal 10 by the inside of transformer 1, master switch 11 links to each other with low pressure leading-out terminal 10 and air circuit 9 by copper (aluminium) busbar 7,8, and is connected with indicating device 13, metering device 12 and Electric capacity compensation device 14 by insulated electric conductor
