Ring network cabinet application

The ring network cabinet has not been around for a long time, but it has been widely used. This is mainly due to the newly developed industrial enterprises and public institution buildings. From the perspective of power supply and distribution, small capacity is the majority Its distribution transformer generally does not exceed 1250KVA, long-term stable power supply, high-voltage switch is not operated frequently. For such users, the performance of the ring network cabinet is not perfect, but it is enough to be competent. With the large-scale urban construction, a large number of large high-rise buildings are pulled up from the ground, and the substation is often located downstairs. According to the fire protection requirements, the substation equipment must be "oil-free" and based on the reasonable use of the construction area Therefore, substation equipment should be "miniaturized", so ring network cabinets or vacuum circuit breakers, dry-type transformers, and dry-type transformers entered the buildings.

The ring network cabinet has a simple structure, reliable and safe operation, small maintenance, and low operating cost. Compared with a switch cabinet equipped with a circuit breaker, the advantages are very prominent. Ring network cabinets require load switches with higher performance and smaller volume. New load switches have emerged, which in turn has led to the technological progress of ring network cabinets. Today's ring network cabinets not only have excellent performance but are serialized. , Which further expands the use of ring network cabinets.
