Price Luanchuan Luanchuan box-type transformer transformer manufacturers

Products plenum Luanchuan box-type substation is generally by the high voltage load switch, high voltage fuses and surge arresters and other components may be made to stop transmission operation and has overload and short circuit protection. Low-pressure chamber by a low-pressure air switch, current transformer, ammeter, voltmeter and other components. Transformers generally use S9 or dry and so on. Box-type variable in electrical equipment components are made of styling products, technical performance components meet the appropriate standards. In order to reliably achieve the five anti-requirements, the electrical components of the mechanical interlock between the use of various electrical components are mounted on the adequate structural strength and rigidity to the wire connection. Operation using electric mode, without reprovision power leads to the TV. In addition also has a box-type variable power detection, display, measurement functions, and to achieve the appropriate protection, it is also a dedicated ground guide, and a clear sign grounding. In addition, to adapt to the outdoor environment, shell top box becomes generally used barrier structure, built with an insulating material, have cooled between the bottom of the box and out of each chamber outlet, with natural air cooling and automatic control of forced air cold and other forms, in order to ensure proper cooling of electrical equipment, with rain, dust, and other measures to prevent small animals from entering. At present, the domestic production of box-type variable voltage levels: high voltage side of 3 ~ 35kV, the low pressure side is 0.4 ~ 10kV. Transformer capacity: When the rated voltage ratio of 35/10, 6, 0.4 kV from several hundred kVA - when the KVA, when the rated voltage ratio of 10, 6 / 0.4 kV from several tens of kilovolts Ann ~ thousand kVA. 1 box-type substation overview and application sets box-type substation, also known as outdoor substation, also known as modular substation, because it has a combination of flexible, easy to transport, migration, ease of installation, short construction period, low operating costs, a small footprint, pollution-free, maintenance-free advantages, widespread attention. Rural power grid construction (reconstruction), and is widely used in urban, rural 10 ~ 110kV sized lesions (distributed) power the factories, mines and mobile operations with the substation construction and transformation, because of its easy depth load center, reducing the power supply radius improve the quality of the terminal voltage, especially for rural power grids, known as the 21st century substation construction target mode.
