The invention discloses a distribution state detection apparatus, including a first distribution equipment onside monitoring unit, a second distribution equipment onside monitoring unit, a third distribution equipment onside monitoring unit, a data acquisition device and a monitoring data center. Each of the first distribution equipment onside monitoring unit, the second distribution equipment onside monitoring unit and the third distribution equipment onside monitoring unit transmits data with the data acquisition device through a wired RS485 mode. The data acquisition device and the monitoring data center utilize a wireless network for transmitting information. The distribution state detection apparatus achieves information acquisition of distribution and utilization user ends, and can detect contact temperature rise, working voltage, current, active power, reactive power, power factor, harmonic content, electric quantity, noise, and insulator leakage current of distribution and utilization equipment.
