Description

A kind of compact open air preassembled transformer station

Technical field

This utility model relates to a kind of preassembled transformer station, is specifically related to a kind of compact outdoor pre- Zhuan Shi transformer station, belongs to Substation Design technical field.

Background technology

Box-type substation is a kind of by high-tension switch gear, power transformer, low voltage switch equipment, The complete power distribution equipment that power factor compensation device, electric power meter are combined into one.Due to Box type transformation is prefabricated by the seller in standing in factory, is therefore greatly saved building time and money Gold, decreases maintenance cost, has saved floor space.Along with urban construction modernization Accelerate, 10kV aerial line is gone underground, it has also become a heat of distribution network transform in recent years Point, and a large amount of 10kV aerial line changes the cable of underground laying into, certainly will eliminate over and commonly use Pole type transformer, box-type substation obtains the most in this context and develops on an unprecedented scale.

Become the practical situation in China's application for American Unit Substation and European-type box, occurred in that in recent years The Novel box of a kind of two kinds of box-type substation advantages of summary becomes compact box-type substation.

Compact box-type substation refers to that those eliminate the high voltage device of American Unit Substation and transformation Device box structure altogether, uses European-type box to become the high-tension switch cabinet having to realize high-pressure side element and change Being separated of depressor, the advantages such as the volume again simultaneously with American Unit Substation is little, cost is low novel Box-type substation.The present situation become with the two kinds of main flow casees that presently, there are is corresponding, and compact is box Transformer station can be divided into based on European-type box change and American Unit Substation two kinds of improved procedures, thus compacts Case becomes two kinds of visibly different structural shapes of existence.

The change of the compactest molding box achieves densification for becoming only with respect to European-type box, because of The compact molding box that these many companies release becomes improvement on the basis of European-type box becomes and realizes, this Improve and focus on following several respects:

(1) solve heat dissipation problem and strengthen Design of ventilation.Low capacity case becomes (below 500kVA) General employing natural cooling ventilates, and becomes forced ventilation to be used for Large Copacity case.

(2) use nonmetal or new material enclosure designs at utmost to stop solar irradiation On case become impact, Ye You company propose case become Landscape Design, in the hope of with natural ring The coordination in border.

(3) technological progress product ripe on domestic market is used, as SF6 looped network is opened Pass, dry-type transformer and Novel low-pressure switch element are in the hope of reducing the volume that case becomes further.

From the point of view of these backgrounds, market is focused on performance study always, ignores people and contact change The defencive function in power station, along with people contact these transformators chance get more and more, some dive In hazardous exposure out, in casing, space efficiency utilization is the lowest, to this end, it is proposed that a kind of tight Gather type open air preassembled transformer station.

Utility model content

The technical problems to be solved in the utility model overcomes existing defect, it is provided that a kind of compact Outdoor preassembled transformer station, due to the setting of infra-red alarm, when people is close or has people During pilferage, alarm sound can be sent in time, remind surrounding population, due to Smoke Sensor and Arranging of suspension type dry powder self-extinguishing device can be taked to answer while realizing terminal induction Anxious measure, it is ensured that safety, can be when light be bad by arranging of warning sign noctilucent coating Wait and also can well alert, remind surrounding population, and these devices are nearly all at box house, It is effectively utilized space, can effectively solve the problem in background technology.
