Core advantages (Why choose oil immersed transformer with OLTC?)

1. Significant energy-saving effect: In response to the current situation where a large number of distribution transformers are operating at low or no-load levels (especially in rural power grids and residential areas), by automatically adjusting to a smaller capacity operation, it can significantly reduce no-load losses, and the comprehensive energy-saving rate can reach 20% - 50%.

2. Does not affect power supply continuity: Due to the on-load switching, users will not experience power outages during the capacity adjustment process, thereby improving power supply reliability.

3. Strong adaptability: It can automatically or manually track load changes to achieve "peak shaving and valley filling" economic operation, solving the inherent problem of low efficiency of fixed-capacity transformers when operating at low loads.

4. Extends equipment lifespan: Operating at a smaller capacity in a low-load state reduces the operating temperature and working intensity of the transformer.

Main working mode and characteristics

1. Large-capacity mode:

● Applicable scenarios: During peak electricity usage periods, such as in the evening during summer, during winter heating periods, or when industrial and commercial activities are concentrated.

● Characteristics: The transformer outputs a rated large capacity, meeting high-load demands, but at this time, the no-load loss is relatively higher.

2. Small-capacity mode:

● Applicable scenarios: During off-peak electricity usage periods, such as late at night, during the Spring Festival holiday, or when the load is very light.

● Characteristics: By using on-load switching to reduce the capacity, the no-load loss (iron loss) can be reduced by 60%-70% or more, which is the key to energy conservation. The load loss (copper loss) will also change with the actual load current.

Main application scenarios

● Rural power grid: There is a significant difference in electricity load between agricultural irrigation seasons and daily usage.

● Residential areas: There are obvious differences in load between day and night, and between working days and holidays.

● Tourist attractions: The load varies greatly between peak tourist seasons and off-peak seasons.

● Commercial districts/schools: The load fluctuates significantly between day and night, and between the academic term and holidays.

● Other occasions with distinct periodic and seasonal load variations.
