Why should the power distribution cabinet be dusted?

Excessive dust will adhere to the electrode, resulting in poor contact, which will make the electrode burn when heated, and lead to discharge when the dust becomes wet.

Electrostatic dust collection: Electrostatic dust collection uses electrostatic field to ionize gas and make dust particles charged and adsorbed on electrodes. In the strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of running to the positive electrode, so that the dust particles are adsorbed by the negative electrode to the positive electrode and collected. Of course, in recent years, through technological innovation, negative plate dust collection has also been adopted. In the past, it was often used in coal-fired factories and power stations to collect coal ash and dust in flue gas.
