Description

TECHNICAL FIELD

[0001] The utility model belongs to the substation technical field, specifically, relate to a prefabricated cabin. BACKGROUND

[0002] Traditional substations are generally civil engineering mode, need to build on site, there are long construction period, great influence on the surrounding environment, large land occupation and other drawbacks. With the increasing tension of urban land, the continuous improvement of residential density, there are problems such as affecting the normal life of residents and the living environment of the surrounding area in the new construction of substations in the city center. In addition to this, the construction of substations in high altitude and other harsh environments also has the problems of long construction period, poor environment, difficult construction, high labor intensity of personnel and so on. In order to solve the above problems, prefabricated cabin type substations with prefabricated cabin structure are widely used, which integrates high-voltage equipment, low-voltage equipment, secondary equipment, bus bridge and other electrical equipment, and also integrates air duct, stairs, air conditioner and other auxiliary equipment. The internal structure of the prefabricated cabin is compact, which can effectively reduce the land occupation. Due to the limitation of transportation size, the prefabricated cabin will be divided into small modules and spliced on site. At present, referring to the drawings shown in Figure 1 、 Figure 2 , the prefabricated cabin type substation is divided in the shape of a Chinese character, which is divided into four subareas, i.e. the first subarea 410, the second subarea 420, the third subarea 430 and the fourth subarea 440. The Chinese character shaped division makes the three rows of screen cabinets in each module arranged in front and back, which makes the wiring path complex when the secondary control factory is wired, resulting in that the secondary connection between the secondary screens can only be completed after the on-site cabin splicing, which has large on-site workload, low equipment integration and difficult quality control.

[0003] In the substation project, cable laying is a key link. In traditional cable laying, the cable is laid after the on-site equipment is positioned, the starting point of the cable list is planned, the length is measured on site, and the cable is cut and laid. It mainly relies on temporary on-site operation. The length data of the cable purchased in advance is calculated by the designer on the two-dimensional drawing according to the path, considering the equipment height, turning radius, margin and other factors, and the human factor dominates, which may cause the same station designed by different people to have different cable length statistics.

[0004] Therefore, a prefabricated cabin is developed, which is divided into functional modules in the secondary equipment cabin, ensures that the secondary equipment is arranged in the same transportation unit, realizes prefabrication and wiring in the factory, effectively guarantees the product quality by using the perfect production and quality inspection mechanism in the factory, and forms a core module mainly composed of electrical equipment, which solves the technical problems.
