Description

Human body electrostatic detector

Technical Field

The utility model belongs to the technical field of electrostatic detection, and particularly relates to a human body electrostatic detector.

Background

Static electricity is common in life and work. The friction can generate static electricity, and when people wear clean work clothes, shoes, walk or work, the static electricity is generated by friction with equipment of different materials, and the people, the clothes and the shoes can be electrified. Static electricity can create a number of hazards. When the ESD current of the human ESD or the ESD of the human ESD exceeds the limit current of the electric shock of the human body by more than 5mA, the human has various nociception, so that the emotion of the staff is uneasy and the operation is wrong. If a human body carries 10KV electrostatic charge, ESD occurs when the foot of the device is touched, and a pulse discharge current peak value can reach 20A when the foot of the device is instantaneously formed to the ground. Spark discharge is commonly encountered in life. In dry winter, after wearing sweater and chemical fiber clothes and walking for a long time, static charges can accumulate on the body due to friction. If the finger is close to the metal object, the hand is felt to have a needled pain, which is caused by spark discharge, and the spark discharge can cause a great danger in certain occasions.
