Direct current blocking device and digital intelligent on-line monitoring direct current blocking fault analyzer

The utility model relates to the technical field of power distribution network lines, and discloses a direct current blocking device and a digital intelligent on-line monitoring direct current blocking fault analyzer which comprise a shell, a capacitor bank and a current collection connector assembly. The two ends of the capacitor bank are respectively provided with a current collection connector assembly, and the current collection connector assemblies are electrically connected with the two ends of the capacitor bank respectively. According to the blocking device, blocking is carried out in a multi-capacitor mode, when the condition that the capacitors are damaged exists, the blocking function can still be achieved as long as one of the capacitors is good, the error-tolerant rate of equipment is increased, and the service life of the whole blocking device is prolonged; according to the scheme, monitoring equipment for independently monitoring multiple capacitors is additionally arranged, sensor modules are
