Description
technical field [0001] The invention relates to a high-voltage test protection device, in particular to a bipolar pneumatic high-voltage and high-power isolation and discharge protection device. Background technique [0002] In the prior art, during the operation of pulsed power devices and other high-voltage tests, a large number of capacitors are charged to a high voltage level. Therefore, it is necessary to conduct high-voltage isolation on the capacitor bank during the experiment, and then perform energy discharge and grounding protection after the experiment. . [0003] Existing isolation and discharge protection devices usually use electric unipolar devices, which are large in size, large in mass, and have poor ability to withstand shock and discharge instantaneously. In the electromagnetic environment, the electric control circuit also has a breakdown conduction with the main circuit or Risk of electromagnetic interference, which can damage the control system.
