The quality of the distribution box is closely related to the transformer of the distribution box, but most people do not understand the transformer of the distribution box, nor do they know what the role of this part is, in fact, the role of the transformer of the distribution box is very large, and relay protection is one of the well-known roles. Through the relay protection can ensure the stability of the current, to ensure that the enterprise does not have any problems in the production process. It can be said that the higher the production demand of the enterprise, the higher the requirements for the transformer of the distribution box will be.As we all know, the current flow of the equipment needs to be controlled within a certain standard, if it exceeds the standard, it will cause damage to the equipment. The transformer of the distribution box can reduce the current through the equipment, ensure that the current is suitable for the equipment, avoid equipment damage due to high current, and fundamentally ensure the smooth production of the enterprise.
