Box-type substation (usually referred to as "step-up substation ") the traditional transformer is centrally designed in the box-type shell, with small size, light weight, low noise, low loss, high reliability, widely used in residential areas, commercial centers, light stations, airports, factories and mines, enterprises, hospitals, schools and other places.
As a complete set of distribution equipment, the box transformer is an organic combination of transformer, high-voltage voltage control equipment and low-voltage voltage control equipment. The basic principle is that through the pressure starting system, armored line, substation automatic system, DC point and corresponding technical equipment, reasonable assembly is carried out in the prescribed order, and all components are installed into a specific waterproof, dustproof and rat-proof and other completely sealed toughened box structure, thus forming a specific transformer. At present, box-type transformers have been widely used in power engineering construction.
The important and indispensable power equipment in power engineering construction. The advantages are as follows:
First, because the internal structure of the step-up substation is more reasonable, it occupies less space. Compared with the traditional transformer, the box-type transformer through scientific and reasonable means to install the high-voltage distribution equipment into a sealed steel structure box, its internal structure is very compact, the gap between the various components is also quite small, so the space occupied by the box-type transformer is also relatively small.
Second, the operation method of the box-type transformer is very simple and convenient, and it is convenient for rapid assembly. Through the understanding of the construction requirements of the power project, the special designer makes a simple and convenient operation of the separate main wiring and supporting equipment outside the box according to different requirements, which is convenient for rapid assembly.
Third, the application of box transformers is high. From the point of view of the creation cost, it can be clearly seen that the creation cost of a box-type transformer is often between 300,000 and 500,000. From the point of view of operating costs, it can be seen that even in the full load operating state, the box transformer consumes about 1 million degrees less electricity than the ordinary transformer every year, and the maintenance cost is less even if there is a problem. Therefore, the box-type transformer has a high application income.
Four, the box-type transformer combination is flexible. Because the box-type transformer has the characteristics of compact and simple structure, each single unit is an independent system, which causes the box-type transformer to have quite strong flexibility in the combination of methods.
Five, box-type transformer operation safety, stability is high. Because the shell of the box-type transformer uses a metal conductor with strong anti-corrosion ability, the interface between the internal equipment and the equipment is also made of insulating materials, and the air conditioning and dehumidification equipment are provided in the box, which greatly improves the resistance of the box-type transformer to the external environment and improves the safety and reliability of its operation.
Six, new energy substations ,.Intelligient control, integrated with enclosure, compact structure and high environmental adaptability for outdoor applications.
Seven, Varelen adopts the oxygen-free copper for winding coil, and only
high quality materials are used for winding and coil insulation as well as isolation. All these make the heat-resistant is up to 220 ℃ for dry type, with excellent overload capacity and low loss, but high effciency.
Why Varelen:
