Description

[0002] A resistor cabinet is a device used to control and adjust resistance. It is mainly used for resistance adjustment in power systems. It usually consists of one or more resistors that can be used to change the resistance value of the circuit, thereby adjusting the current and power of the circuit. The resistor cabinet can be used in various applications, such as resistance starting motors, current limiting and voltage regulation. In some special applications, the resistor cabinet can also be used to simulate resistive loads or test the stability of the circuit.

[0003] The resistor cabinet will generate a lot of heat inside during use, which will cause some electrical components inside the resistor cabinet to age faster and also cause certain damage after long-term use. Moreover, while the resistor cabinet is ventilated and dissipated, dust from the outside air will easily enter the device, causing a large amount of dust to accumulate inside the device over time. Some devices are equipped with filters on the surface, but long-term use will cause a large amount of dust on the filter surface, which will affect ventilation and reduce the heat dissipation effect.
