Causes of fan power distribution box malfunctions
During the use of fan distribution box, because the capacity selection of AC contactor is not very appropriate, AC contactors with the same capacity are installed for different outgoing circuits, and the imbalance of three-phase load is not considered, the current level of some. Each piece of electrical equipment on a distribution system has a probability of failing. When first installed, a piece of equipment can fail due to poor manufacturing, damage during shipping, or improper installation. Troubleshooting is the effort to identify and resolve differences between design intent and actual performance. However, in actual applications, distribution boxes often encounter a series of problems, which not only affect the normal operation of the power system, but also may bring safety hazards. When they start tripping, overheating, or making strange noises, it's more than just an inconvenience - it's your home's cry for help. There may be several factors that could make the fan to stop responding to speed adjustment, but technically in the engineering point of view, this could be caused by the defect in the speed regulator of the fan.
