Transformer oil serves as the primary insulation and cooling medium for oil-immersed transformers. The quality of its electrical strength and chemical composition directly impacts the performance of the transformer. If the oil contains trace amounts of moisture and impurities, it can reduce ins...

Dry type transformers are easy to operate and maintain due to their flame retardant and self extinguishing properties, high mechanical strength, and large short-circuit capacity they can withstand. However, in the case of poor ventilation, the heat dissipation performance of dry-type transforme...

Beneath transformers, especially large oil-immersed ones, we often observe a layer of pebbles (or gravel layer) laid down. This is not for aesthetic purposes but a carefully designed safety measure, primarily aimed at: Fire Prevention: The pebbles help contain and extinguish fires by preve...

New energy inverters are key devices that convert direct current energy into alternating current energy, widely used in fields such as solar photovoltaic and wind power generation. As an important component of inverters, electronic transformers play a crucial role. This article will explore the...

The difference between high-voltage circuit breakers and isolating switches High voltage circuit breakers (or high-voltage switches) are the main power control equipment in substations, with arc extinguishing characteristics. When the system is operating normally, they can cut off and connec...

Box type substations, also known as box type transformers, prefabricated substations, etc., are divided into American type box transformers and European type box transformers. The electrical equipment components in the box type substation are all selected from standardized products, and the te...
