SYB-12/0.4 prefabricated substation

الوصف

SYB**2/0.4 pre-assembled substation is a high-efficiency power distribution unit consisting of a high-voltage room, a transformer room and a low-voltage room. It is suitable for power systems with a rated voltage of *2KV. With the characteristics of complete sets, small footprint, movable, reasonable structure, beautiful appearance, easy installation and maintenance and low investment, it is suitable for residential communities, large construction sites, industrial and mining enterprises and institutions, high-rise buildings, urban street light distribution, oil fields, mines, narrow streets, temporary power supply and other places. The switchgear can meet the requirements of technical standards such as GB*********1 and has the functions of "five preventions" to prevent misoperation of the circuit breaker; to prevent pulling the switch with load; to prevent closing the earth switch with electricity; to prevent sending electricity when the earth switch is in the earth position and to prevent entering the electrically charged interval by mistake. 4.1 The series of products are of frame structure, made of The steel sections are welded by special anti-corrosion treatment. The shell can be made of cold-rolled steel with plastic spraying on the surface. The top of the box is a double structure with heat insulation and exhaust cooling.
4.2 All operations are carried out in the closed state of the cabinet door. With perfect and effective "five prevention" function, to prevent misoperation.
4.3 Inlet and outlet modes: high-voltage cable in, low-voltage cable out; high-voltage cable in, low-voltage overhead out; high-voltage overhead in, low-voltage
cable out; high-voltage overhead in, low-voltage overhead out.
4.4 The primary power supply system on the high-voltage side can be arranged in a variety of power supply modes such as ring-net power supply, terminal power supply and dual power supply, etc. High-voltage metering components can also be installed to meet the requirements of high-voltage metering.
4.5 The transformer room can be selected from S*1 and other low-loss oil-immersed transformers and dry-type transformers; the transformer is equipped with an automatic forced-air cooling system and lighting system. Natural ventilation and forced ventilation are used for cooling, with good ventilation and cooling performance. The transformer room has a temperature control instrument, which can automatically control the temperature of the transformer room to ensure that the transformer runs at full load.
4.6 The low-voltage room can adopt fixed or drawer structure according to users' requirements, with various functions such as power distribution, lighting distribution, reactive power compensation and power metering to meet users' different requirements and facilitate users' power supply management and improve power supply quality.
4.7 Low-voltage and high-voltage rooms can be equipped with heaters respectively to prevent condensation.
