Description

Technical Field

[0001] The present invention relates to the technical field of static elimination, and particularly to a static elimination protection device for a power distribution cabinet. Background Art

[0002] A power distribution cabinet is a general term for a motor control center, which is used in multiple fields, such as mining, smelting, chemical industry, textile, medicine, food processing, and building materials industries. These industries have a common feature, that is, there is a large amount of dust in the working environment. During the floating and storage processes of these dusts, it is inevitable that frequent impacts, frictions, and separations occur between the powder particles and between the powder body and the container wall. As a result, contact, separation charging effects and frictional charging effects will be generated, causing the power distribution cabinet to be charged with static electricity.

[0003] When there is a large amount of powder static electricity on the power distribution cabinet, due to its relatively high resistivity, the accumulated static electricity is not easily leaked, thus forming a strong electrostatic field. This electrostatic energy can cause insulation breakdown, electric shock, and fire and explosion. Summary of the Invention
