I, Overview
A box-type transformer, also known as an American transformer, is a transformer that compactly combines the transformer and its accessory equipment in a metal enclosed box. Because of its advantages of compact structure, easy installation, safe and reliable operation, box-type transformers have been widely used in power system, industry and commercial fields. This construction scheme aims to guide the installation and construction process of box-type transformer to ensure the quality and safety of the project.
Second, construction preparation
- Design review: Ensure that the box-type transformer installation design meets the relevant standards and specifications, including electrical safety, fire prevention, moisture and other requirements.
- Site investigation: understand the site environment, determine the basic position of the transformer, cable access holes, etc.
- Equipment acceptance: Check whether the specifications and models of the box-type transformer and its accessories meet the design requirements, and whether there are damages or defects.
- Tools: Prepare tools and devices required for installation, such as lifting equipment and electrical test meters.
Third, construction steps
- Basic production: Make transformer foundation according to the design drawings to ensure the stability and level of the foundation.
- Equipment lifting: Use lifting equipment to lift the box-type transformer to the center of the foundation and fix it.
- Cable connection: According to the design requirements, connect the high voltage cable, low voltage cable and control cable of the transformer. Cables should be securely connected and well insulated.
- Transformer commissioning: Electrical testing of the transformer, including insulation resistance test, voltage test, etc., to ensure the normal operation of the transformer.
- Installation of protective facilities: install moisture-proof, dust-proof, rat-proof facilities as required.
- Acceptance and handover: Acceptance shall be carried out after the completion of construction to ensure compliance with design requirements and relevant standards. After passing the formalities, the transformer will be delivered to the user.
Four, Precautions
- The construction process shall follow the relevant safety operation procedures to ensure the safety of personnel.
- For dangerous areas and live equipment, appropriate safety measures should be taken, such as setting fences and hanging warning signs.
