Faults caused by product quality In the transformation of the rural power grid, due to the large number of distribution boxes required and the short construction period, the distribution box factory needs the supply time and quantity of low-voltage electrical appliances, which resulted in the phenomenon that the requirements for product quality are not strict, resulting in the failure of some products shortly after they were put into operation. For example, some types of AC contactors cannot operate shortly after the distribution box is put into operation because the contactor closing coil is burned out.

Faults caused by improper selection of electrical appliances in the distribution box Due to the improper selection of AC contactor capacity during manufacturing, AC contactors with the same capacity were installed for different outlet circuits, and the imbalance of three-phase load was not taken into account, and the current level of some outlet contactors could not be increased by a current level selection based on the normal selection model. improvement
