Background
Currently, power distribution units (power distribution units) are widely used in various computer rooms (e.g., data centers) to distribute power required by various devices. However, as the equipment in the machine room becomes more complicated, a plurality of power distributors may be used in one machine room, and the same power distributor is often electrically coupled to different equipment, so that the circuit configuration of the whole machine room is more complicated and complicated, and thus, the personnel in the machine room often need a lot of time to perform troubleshooting; while arcing is a gas discharge phenomenon, a transient spark generated by the passage of current through some medium. An arc is a self-sustaining gaseous conductor whose majority of carriers are electrons generated by primary electron emission. The surface of the contact metal is subjected to electron escape due to primary electron emission, and gas atoms or molecules in the gap are ionized to generate electrons and ions. In addition, secondary electron emission can be caused by electron or ion bombardment on the emission surface, and when the ion concentration in the gap is large enough, the gap is broken down electrically to generate electric arcs; in the working process of various types of electrical equipment, due to the fact that wiring is not standard or careless and careless leakage occurs in the operation process, an electric arc phenomenon can occur, normal use of the electrical equipment is affected, and certain dangerousness exists, so that the requirement on the performance of a power supply source is high, and particularly in a high-voltage direct-current distribution unit, the problem that electric arcs are generated when output jacks are plugged and unplugged is urgently needed to be solved so as to ensure the safety performance, the service performance and the service life of the equipment.
