1. Selection Precautions
Packaging Integrity & Safe Transport: Ensure packaging remains intact, with legible and appealing print, and complete labeling (including factory name, trademarks). During transportation, take precautions to mitigate collisions and vibrations, preserving the product's condition.
Safety Compliance Verification: Validate that the transformer meets both national and industrial safety benchmarks, complemented by robust safety measures.
Environmental Focus: Prioritize transformers with superior environmental performance, selecting low-noise, low-emission options that align with environmental requirements.
2. Transformer Applications in Renewable Energy
Hydroelectric power plants: Utilizing the kinetic energy of flowing water, hydroelectric power plants drive turbine generators to produce electricity, which is converted to the necessary voltage by transformers. Transformers in these plants step up low voltage power for efficient long-distance transmission over transmission lines. In the substation room of a hydroelectric power plant, a step-up transformer increases the low-voltage power (e.g., 400 V) generated by the turbines to a higher voltage (e.g., 35 kV, 110 kV, or more) suitable for long-distance transmission. This high-voltage approach effectively minimizes power loss during transmission and ensures that electricity is delivered safely and reliably to users.
