Problems solved by technology
The power distribution devices are arranged on different floors of the comprehensive substation building, and cables are generally used to connect electrical equipment of various voltage levels. The number of cables is large, the investment is high and it is easy to cause crossover
The design of substation ventilation and air-conditioning system usually adopts the form of centralized ventilation and air-conditioning system, which leads to unnecessary consistency of ventilation volume and temperature level in each functional room, which wastes energy and does not meet environmental protection requirements

The invention relates to a compactly arranged 220kV all-indoor transformer substation. The transformer substation comprises a building, a plurality of main transformer units, 220V / 110kV gas-insulatedmetal-enclosed switchgear, a 10kV switch cabinet, a 10kV arc suppression coil grounding transformer sleeve device and secondary equipment. The interior of the building is divided into a first space, asecond space and a third space in the Y-axis direction of the rectangular coordinate system, the second space is further divided into a first subspace and a second subspace, and the third space is further divided into a third subspace and a fourth subspace. The main transformer units are arranged in the first space; the secondary equipment is arranged in the first subspace; the 10kV switch cabinet and the 10kV arc suppression coil grounding transformer sleeve device are arranged in the second subspace; the 220kV gas-insulated metal-enclosed switchgear is arranged in the third subspace; and the 110kV gas-insulated metal-enclosed switchgear is arranged in the fourth subspace. The total occupied area of the transformer substation can be reduced, and equipment arrangement is more compact andreasonable.
Description
technical field [0001] The invention relates to the technical field of power transmission and transformation engineering design, in particular to a compact layout scheme of a compactly arranged 220kV indoor substation. Background technique [0002] With the vigorous advancement of my country's urbanization level, residents' electricity load continues to increase, but urban land resources are scarce and land acquisition is difficult, so higher requirements are put forward for substation design. According to the nature of power load, capacity, environmental conditions, operation and maintenance requirements, it is necessary to reasonably select equipment and formulate layout plans, adhere to the principle of saving land, and meet the requirements of ventilation, heat dissipation and noise reduction. [0003] At present, the existing 220kV indoor substation generally adopts double-winding or three-winding transformer horizontal split layout, the amount of silicon steel sheets a...
