The invention discloses a low-voltage distribution line shunt monitoring device and a monitoring method thereof. The monitoring device comprises an upper cover and a lower cover. The upper cover is connected to the lower cover through a rotation shaft. The upper cover can be opened and closed along the rotation shaft. An electricity taking coil and a current measuring coil are installed in position grooves of the upper cover and the lower cover. The electricity taking coil and the current measuring coil are provided with elastic copper sheets used for voltage detection, and a main control circuit board is arranged in the lower cover. The main control circuit board includes a main control MCU, an electricity taking management circuit and a voltage detection circuit, wherein the electricity taking management circuit and the voltage detection circuit are electrically connected to the main control MCU. The main control MCU is electrically connected to the electricity taking coil and the current measuring coil through an AD port. The structure of the device is simple, a non-contact type monitoring device integrating induction electricity taking, a current, a voltage and temperature detection into one body is adopted, a line or external power supply does not need to be connected into from a distribution line, safety of monitoring personnel is protected, and simultaneously, installation is quick, operation is simple, and cost is low. .
Description
technical field [0001] The invention relates to the technical field of electric power Internet of Things application, in particular to a low-voltage distribution line branch monitoring device and a monitoring method thereof. Background technique [0002] The intelligent low-voltage shunt monitoring device is mainly installed on the low-voltage distribution cables of the switching station, ring main unit, and distribution transformer low-voltage chamber. It is suitable for power monitoring and fault detection of 400V lines, and can collect operating current, voltage, Information such as the temperature of the cable skin can be used to calculate the active and reactive power of the line. When the line fails, it can detect the line fault current and give an alarm to realize the information management and active repair service of the low-voltage power grid. [0003] At present, the low-voltage shunt monitoring device converts the 380V or 220V of the power distribution line into ...
