| description | The invention discloses an intelligent station bus secondary voltage monitoring method and device. The method comprises the steps of: obtaining a first digital bus secondary voltage in real time by abus merging unit, and accordingly determining whether the bus voltage value is abnormal; if so, converting an analog secondary voltage in a bus bar control cabinet by a second AD conversion module andoutputting a digital second digital bus secondary voltage; comparing the first digital bus secondary voltage with the second digital bus secondary voltage; if the first digital bus secondary voltageis inconsistent with the second digital bus secondary voltage and the second digital bus secondary voltage is normal, determining that the fault is a bus merging unit fault; and if the first digital bus secondary voltage is consistent with the second digital bus secondary voltage, determining that the fault is a non- bus merging unit fault. The monitoring device is applicable to the intelligent station bus secondary voltage |
