Description

Technical field: [0001] The invention relates to the field of cleaning devices for electrical equipment, in particular to a device for cleaning and treating dust inside high-voltage electrical equipment. Background technique: [0002] Dust has a great impact on high-voltage electrical equipment, especially some precision electrical equipment and connectors. If dust is deposited on integrated blocks and other electronic components, it will reduce their heat dissipation performance and cause integrated blocks and other electronic components. Components can not work properly, or even damaged. Some conductive dust falls into the electrical equipment, which will reduce the insulation of the relevant materials and cause a short circuit. On the contrary, insulating dust may cause poor contact of the connector contacts. Power equipment has been exposed to the air environment with severe pollution for a long time. Salt (such as sulfide, phosphide, ammonium salt, sodium chloride, etc...

Problems solved by technology

What's more serious is that the electrochemical action produced by the water film containing salty electrolyte formed by condensation and dissolution due to air humidity causes electrochemical corrosion. Once this pollution corrosion occurs, it is irreversible.

The harm caused by pollution to the operation of power equipment: the fine dust in the environment deposits on the outer insulating surface to form a layer of dirt, which contains metal particles, oil, dust, and moisture-soluble salts, acids, and alkalis. When exposed to humid conditions such as fog, dew, and drizzle, the conductance increases, the insulation performance decreases, and phenomena such as leakage, pollution flashover, and flashover are prone to occur; the metal surface is subjected to the action of oxygen in the air, and a layer of oxide will be formed, which will As a result, the resistance of the contact increases, which in turn causes the temperature of the contact to rise, which is prone to flashover; due to the electrostatic effect near the equipment, the dust is polarized or even ionized, adsorbed on the surface of the charged body, and the polarized dust extends to a certain extent. It is easy to cause discharge; if the contacts are polluted by dust or other substances, the resistance will increase, the Joule heat will increase, and in serious cases, it will cause a fire. Therefore, how to effectively clean the electrical equipment and keep the surface and interior of the equipment clean is especially important for the normal operation of the equipment. important

At present, in the process of cleaning the surface of electrical components and various components in the switch cabinet, ordinary high-pressure air blowing equipment is usually used to clean them. During the cleaning process, the dust on the equipment can only be removed by airflow Cleaning, but in the process of cleaning, some dust attached to the surface of the device cannot be effectively cleaned, and in addition, it cannot be cleaned more effectively in some small spaces; in summary, it is obvious that the existing dust cleaning Devices do not serve people's needs more effectively
