Substations transform the power system voltage, the acceptance and distribution of electricity, control the power flow and adjust the voltage of the power facilities, it will at all levels through its transformer linked voltage grid, is part of the power system. Substation is composed of a series of equipment, power conversion, in which contact, transformer, distribution.Substation, including all types of equipment: transformers, circuit breakers, load switches, busbars, current transformers, voltage transformers and so on.
This article is a 35 kV electrical substation parts of a design. The design is based on the actual load for substation based on the best run, in accordance with the relevant regulations and norms, the area was completed to meet the power requirements of the preliminary design of the 35kV substation.This article is divided into eight parts, which mainly include the design of the main terminal, the load, the transformer option, the choice of high-voltage electrical appliances, lighting transformer substation layout of mine and so on.
The substation has 2 main transformers, two power supply into line, 35 kV and 10 kV high-voltage side are high-pressure side of a single sub-bus architecture. The design of the main electrical wiring diagram for a type of demonstration, and a short-circuit current calculation.At the same time also the main electrical equipment (including circuit breakers, load switch, isolation switch, current transformer, voltage transformer) to the selection and validation. Also lighting and lightning protection grounding configuration of the protection of a design and calculation. Substation with a floor plan, high-low-voltage configuration diagram, floor plan and lighting transformer substation then mine map.
