Pre-installed Transformer Substation description
AC metal closed type shift switch cabinet is a three-phase AC 50HZ indoor device metal-enclosed switchgear, used in power plants and substation systems with a rated voltage of 35kV, a rated maximum current of 2000A, and a single bus or section with a maximum voltage of not more than 40.5kV Busbar sets of power distribution equipment.
The switchgear meets the requirements of DL/t404-91, IEC298, GB3906 and other standards, and has the functions of preventing misoperation of the circuit breaker, pushing the trolley with load, grounding wire, power transmission with grounding wire and accidental charging. Interval (called "five preventive measures").
Box-type substations are suitable for residential areas, urban public transformers, prosperous urban areas, and building electricity. Users can choose box type changes according to the conditions of use and load level. Since the advent of the box-type substation, it has developed rapidly. In developed countries, 70% of distribution transformers have been developed, while the United States has accounted for 90%. The rapid development of China's urban modernization and the transformation of urban distribution networks will be widely used.
Box-type substations are used in high-rise residential buildings, luxury villas, square parks, residential areas, small and medium-sized factories, mines, oil fields and temporary buildings to receive and distribute electricity in the power distribution system.
