HIGH-SPEED INTRODUCTION DEVICE, POWER CONVERSION DEVICE AND SWITCHGEAR

A fault current is removed at a higher speed. A high-speed introduction device includes: a connection chamber provided in an insulative container; a first electrode and a second electrode disposed to be electrically separated from each other in the connection chamber at least before an introduction operation, each of the first electrode and the second electrode being composed of a conductive material; and an injector to inject at least one of a charged particle and a conductive particle, the injector communicating with the connection chamber, wherein when the introduction operation is started, the injector injects at least one of the charged particle and the conductive particle into the connection chamber.
