Specific requirements for installation height of dry-type transformer
Ground installation: The height of the transformer pier installed on the ground is generally 0.5 meters. Guardrails of no less than 1.7 meters should be installed around it, and warning signs should be hung in obvious positions.
Pole installation: For dry-type transformers of 315kVA and below, pole installation can be adopted. The bottom should not be less than 2.5 meters from the ground, and the energized part should not be less than 3.5 meters from the ground.
Distance from walls and other obstacles: In general, dry-type transformers should be 800mm away from walls and other obstacles, and there should be a distance of 300mm between adjacent transformers.
Factors affecting the installation height of dry-type transformers
The installation height of dry-type transformers is affected by many factors, mainly including the following aspects:
Transformer type and capacity:
Dry-type transformers of different types and capacities differ in structure, heat dissipation method, etc., so their installation heights will also be different. Generally speaking, large-capacity transformers require better heat dissipation conditions, so higher installation heights or more spacious installation spaces may be required.
Installation environment:
The humidity, temperature, dust and pollution prevention of the installation environment will also affect the installation height of the transformer. For example, in a humid environment, in order to improve the moisture-proof performance of the transformer, it may be necessary to increase the height of the shielding or take other moisture-proof measures.
Operation and maintenance requirements:
The operation and maintenance of transformers include daily inspections, troubleshooting, regular maintenance, etc. These operations require certain space and height conditions. Therefore, when installing the transformer, the operation requirements and safety factors of the operation and maintenance personnel need to be fully considered.
Safety specifications and standards:
The country or industry has clear specifications and standard requirements for the installation height of dry-type transformers. These specifications and standards are intended to ensure the safe operation of the transformer and the safety of life and property of personnel.
Why should dry-type transformers be installed off the ground?
The main reasons for installing dry-type transformers off the ground include moisture-proofing, reducing dust accumulation and facilitating maintenance. Placing the outer cover of the dry-type transformer off the ground can effectively avoid the impact of humid environments on the equipment, prevent the equipment from getting damp, and thus extend the service life of the equipment. In addition, off-the-ground installation can reduce dust accumulation. Especially in outdoor or dusty environments, off-the-ground installation can reduce the impact of dust on equipment performance and ensure stable operation of the equipment. Finally, off-the-ground installation makes daily maintenance and overhaul more convenient, helps to find and solve problems in a timely manner, and ensures the safety and service life of the equipment.
The installation height of dry-type transformers is a complex issue involving many aspects. During the installation process, it is necessary to fully consider factors such as the type, capacity, installation environment, and operation and maintenance requirements of the transformer, and follow relevant safety regulations and standards. Through scientific and reasonable installation design and construction operations, the safe operation of dry-type transformers and the safety of life and property of personnel can be ensured.
