Transformer iron core and clamp member current standard exceeding alarm instrument

The invention discloses a transformer iron core and clamp member current standard exceeding alarm instrument comprising two sensors, a conductive wire, a conditioning circuit, a transmission wire, a control box, a display screen, an MCU, an alarm device, a converter, a power supply and a battery. The external side of one of the sensors is sleeved by the conductive wire, and the other sensor is arranged at one side of the conductive wire. The two sensors are connected on the conditioning circuit. The conditioning circuit is connected on the control box via the transmission wire with a shielding layer. The display screen, the MCU, the alarm device, the converter, the power supply and the battery are installed in the control box. The MCU is respectively connected with the display screen, the alarm device, the converter and the power supply. When milliampere-level micro alternating current is measured by the device under the environment of strong electromagnetic interference, the instrument does not need to be close to the measured conductive wire through manual operation, influence generated by electromagnetic interference in the environment is eliminated from the measurement result, current can be automatically and continuously measured in real time and displayed after installation, and the instrument has an automatic alarm function when current exceeds the set value.
