1.
Cabinet fault characteristics caused by electrostatic ;
a.
Season of static electricity failure occurs, mainly dry winter and spring, that is static change with humidity.
;
b。
Static electricity caused as a result of the accidental, repeatability is not strong, is generally random failure, therefore, difficult to find out the reason of its cause.
;
c。
The floor of electrostatic and computer use.
Use of furniture and the staff work clothes on.
;
d。
Electrostatic send electronic cabinets appear error action, often is when the human body or other insulators and cabinet equipment occur when in contact.
;
2。
Electrostatic discharge cause of cabinet failure ;
a.
Since the instantaneous current flows through the casing, and signal lines and power cord induced noise.
;
b。
Due to the high voltage electrostatic generation, on the ground, the safety of potential changes, leading to logically the potential changes.
;
c。
Due to the contact part of the application of electrostatic discharge electromagnetic waves for radiation noise of signals.
