The invention provides an electric network equipment data multidimensional association analysis system and a cleaning device thereof. The electric network equipment data multidimensional association analysis system and the cleaning device thereof aim to solve the problem of dust cleaning of a server of the electric network equipment data multidimensional association analysis system in an existing technical scheme. The electric network equipment data multidimensional association analysis system comprises a system server, and the system server comprises a shell body and the cleaning device arranged in the shell body; and the cleaning device comprises a dust blowing device and an exhaust vent formed in the shell body, and the cleaning device further comprises an electrostatic dust collector arranged at the exhaust vent and a dust collector cleaning device used for cleaning the electrostatic dust collector. The electric network equipment data multidimensional association analysis system and the cleaning device thereof have the beneficial technical effects that after the dust blowing device conducts dust blowing, gas flow flows toward the exhaust vent from the inner portion of the shell body, because the electrostatic dust collector is arranged at the exhaust vent, the electrostatic dust collector absorbs dust in air efficiently, accordingly, the amount of the dust settling at the bottom of the system server or on elements is reduced, and the better dust removal effect is achieved; and when the dust on the electrostatic dust collector reaches to a certain amount, the dust on the electrostatic dust collector can be removed through the dust collector cleaning device.
