When the fault Arc inside the medium-voltage (MV) metal enclosed switchgear happens, the arc heats the filling gas in the switchgear, resulting in pressure rise, which may seriously damage the electrical equipment and building and may even endanger personnel. In order to put forward an appropriate calculation method to calculate the pressure effect caused by the internal arc in the MV switchgear with...
For handheld products, package size is required as small as possible, new packaging technology such as wafer level chip scale packaging (WLCSP), stacking die, 3D packaging is developed quickly. So far, wafer level packaging is realized in mass production and accepted by most of semiconductor enterprises. However, mechanical reliability is the great concern for WLCSP products usage. The primary driving...
A triggered vacuum switch (TVS) is an important component in pulsed power systems due to its quick switch, rapid dielectric recovery, small volume, convenient trigger system, simple structure, etc. A sample of field-breakdown TVS is fabricated, and its turning-on process is described in this paper. The initial plasmas play an important role in the process of TVS operation; its development includes...
