Power distribution cabinet is a general term for motor control center. The power distribution cabinet is used in situations where the load is relatively scattered and there are few circuits; the motor control center is used in the situations where the load is concentrated and there are many circuits. Power distribution cabinets are further divided into low-voltage power distribution cabinets and high-voltage power distribution cabinets, while high-voltage power distribution cabinets refer to the functions of on-off, control or protection in power generation, transmission, distribution, power conversion and consumption of power systems, mainly including High-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices and high-voltage switch cabinets, etc. The current and devices cause the temperature inside the power distribution cabinet to be very high, which can easily cause circuit short circuits and fires. When people install the power distribution cabinet, they often place cooling fans to dissipate heat in time. In other words, its fan frame determines whether the cooling fan can work for a long time.
