The installation of dry-type transformers is an important task that requires adherence to a series of requirements and standards to ensure a smooth installation process and the normal operation of the transformer. Below is a detailed list of the installation requirements for dry-type transformers:

1. Installation Environment

1. Dry-type transformers should be installed in indoor locations with good air circulation, free from corrosive gases and minimal dust, avoiding proximity to flammable materials and harmful gases.
2. The room should be clean, without other non-structural penetrating facilities, and the roof should be waterproof.
3. The transformer foundation must meet load, anti-vibration, and bottom ventilation requirements.

2. Installation Location

1. Transformers should be installed indoors, and the installation ground must be flat, stable, and meet the load-bearing requirements for the transformer.
2. There should be sufficient clearance between the transformer and the wall to facilitate maintenance and heat dissipation.

3. Installation Steps

1. Construction Preparation:

• Unboxing Inspection: Personnel from the power plant, manufacturer, material company, and electrical professionals should participate.
• Foundation Channel Steel Installation: Ensure it is secure, leaving cable entry holes that meet design requirements.

2. Transformer Installation:

• Transformer Transportation: With the assistance of riggers, transport the transformer to the distribution room. The transportation process should be slow to prevent excessive impact, and brown ropes should securely seal the vehicle; it is strictly prohibited for people and goods to share the same vehicle.
• Transformer Positioning: Use rollers and pry bars to move the transformer to the correct installation position. Sufficient manpower should be used during movement, with unified command and consistent force.
• Weld and fix the transformer base to the foundation channel steel.
• Transformer Enclosure Installation: Collaborate with the manufacturer to assemble the transformer enclosure properly, welding and fixing it at all four corners to the foundation channel steel.

4. Safety Precautions

1. Before using electric tools, always check their insulation performance to ensure there is no leakage, and ensure that the casing is reliably grounded.
2. Wearing gloves while using a drill is strictly prohibited.
3. Construction personnel at the dry-type transformer site must wear qualified protective clothing and safety helmets.
4. Do not damage the lead wire bushings or other accessories of the dry-type transformer.
5. Before conducting live trial operation of the dry-type transformer, always check the secondary circuit to ensure its correctness.

In addition, pay attention to the following points:

1. The temperature controller for the dry-type transformer should be installed in a prominent position for easy observation and operation.
2. Doors should be made of non-combustible materials and should open outward. The door should have equipment names and safety warning signs, while safety facilities such as protective mesh doors and railings should be complete.
3. During installation and maintenance work, strict adherence to operating procedures is required, protective gear must be worn, and contact with exposed wires and high-voltage components should be avoided.

In summary, installing a dry-type transformer requires comprehensive consideration of multiple aspects including environment, location, steps, and safety. During installation, it is essential to follow relevant standards and specifications to ensure installation quality for safe operation and use of the transformer.
