A brush discharge is an electrical disruptive discharge similar to a corona discharge that takes place at an electrode with a high voltage applied to it, embedded in a nonconducting fluid, usually air.

2018年11月8日 · According to NFPA 77-2019, it can be in the form of a “spark, corona discharge, brush discharge, bulking brush discharge, or propagating brush discharge.” More often than not, efforts to mitigate static electric discharges are intended to protect computer components and other materials sensitive to static electricity.

Brush discharges happen when an isolated material is getting charged, for example a flexible drop tube. The movement of the powder is charging the material but as it is not conductive, they cannot be released and keep building up.

The meaning of BRUSH DISCHARGE is a faintly luminous relatively slow electrical discharge having no spark.

2024年6月20日 · The type of electrostatic discharge that occurs from insulating materials with a single layer of charge is called a brush discharge because of its brush-like appearance (Figure 4). When a brush discharge occurs, a limited area of charge is discharged from the surface of the insulating material.

Propagating Brush Discharge Propagating brush discharges are very important; they are believed to be the major contributor of static electricity ignitions. They occur between a conductor and a nonconductive lining on another conductive surface.

2014年4月1日 · A brush discharge occurs from an electrostatically charged insulator to a grounded conductor. Typical possible sources of static electrical discharges include the following: • Spark discharges from any conductive, but not earthed (grounded), bag, bin, drum, container and so on, from which a powder is transferred into a reactor

2017年8月1日 · Two types of discharge, brush and propagating brush discharges, can occur on a charged insulating coat or liner in contact with a grounded conductor when a grounded object approaches it.
