— 产品中心 —300kV electrostatic test system
When aircraft, rockets, missiles or weapon system in high speed, and the dust in the air, rain, snow, such as a charged particle collision, in the surface of the system can produce hundreds of kV static accumulation, when accumulated to a certain degree of the charge, the non-uniform electric field on the surface of the system would have a high frequency of dust surrounding the corona discharge, and during loading or transportation process can produce high voltage electrostatic discharge, the discharge of high frequency pulse may cause interference on the system itself or other equipment, resulting in system dysfunction and failure phenomenon, If the static electricity is released onto the exposed lead of the fuse's electric explosive device or onto the electric circuit (HESD) connecting the manipulator or related equipment and ammunition, serious consequences such as accidental detonation of the electric explosive device may occur.
The electrostatic discharge generator is to simulate aircraft flying high in the sky after wearing very high electrostatic can be safe and reliable in normal work or damage to the special generator, such as the maximum voltage of 360 kv, which can realize deposition, lifting electrostatic charge, as well as high pressure electrostatic discharge test, fully comply with MIL - STD - 464 - c, MIL - STD - 331 - c, AECTP - 250, GJB1389A, GJB573A, GJB8848 standard, etc.

Note 2: since the resistance cannot be designed to be absolutely non-inductive, the distributed inductance is less than 10 minus H
Note 3: when using the built-in coaxial current probe, the connection point of the whole system shall be the position of the lower end of the calibrated resistance closest to the measuring end to ensure that the measuring signal will not be affected by ground potential. This output signal is used as the reference current display. For more accurate current display, please select the mutual inductance current coil probe for measurement.
