Installation Instructions:
1. Installation form:
The versatile installation forms for 20kV oil-immersed transformers include strategic pole-mounted setups, resilient outdoor installations, and seamless indoor transformer arrangements. Each option is designed to optimize operational efficiency and adaptability to varying environmental conditions.
When installing outdoors, secure the transformer on a reinforced concrete foundation to ensure stability and safety. For indoor installations, align the transformer body precisely with the cabinet front, ensuring a seamless fit with the distribution panel, eliminating any gaps for optimal performance.
2. Installation steps:
During the precise placement of the transformer, make use of specially designed force points. Implement robust anti-slip measures to maintain stability and prevent any movement during installation, ensuring the transformer remains secure and functional.
Control the inclination of the transformer body within strict parameters during transportation and installation, maintaining an angle of no more than 15° in the long axis direction and no more than 10° in the short axis. This ensures structural integrity and optimal performance.
During installation, vigilantly monitor the spacing between components, avoiding excessive tightness or looseness. This careful adjustment ensures efficient operation and prolongs the lifespan of the transformer.
When installing terminals, choose insulation disks with precision to suit the specific conditions, ensuring correct wiring connections for safe and efficient electrical operation.
3. Attachment installation:
Installation of crucial accessories, including gas relays, pressure relief devices, moisture absorbers, and sleeves, must adhere strictly to industry standards and manufacturer guidelines. This guarantees safety, reliability, and optimal function of the transformer system.
