The invention relates to a distribution transformer load side current acquisition fault alarm device comprising a processor which is connected with a plurality of current sensors. The plurality of current sensors are respectively installed at the front end of a three-phase inlet wire of the low-voltage side air switch, and the processor collects current data of the current sensors in real time and stores the current data in the memory. According to the method, the fault handling efficiency can be effectively improved, the load rate of the distribution transformer and the matching rate of the low-voltage side air switch can be checked, and the problem of frequent tripping of the air switch is visually solved. And the power supply reliability and customer satisfaction are improved. 本发明涉及一种配电变压器负荷侧电流采集故障报警装置，包括处理器，处理器与若干电流传感器连接；若干电流传感器分别安装在低压侧空气开关三相进线前端，处理器实时采集，电流传感器的电流数据，并把其电流数据保存在储存器内。本发明可以有效提升故障处置效率并可以对配变的负载率和低压侧空气开关的匹配率进行核对，直观的解决空气开关的频繁跳闸问题。提高供电可靠性和客户满意度。
