The clamp-type measuring head adopts a clamp-type design, can be conveniently clamped on a communication power cable, and does not need to disconnect a power supply. The clamp-type head is internally provided with an induction coil which can induce a current magnetic field in the cable and transmit an induction signal to the measuring transducer. The measuring converter part converts the signal sensed by the clamp type measuring head into a measurable electric signal, and the measuring converter part performs data processing and conversion through the built-in signal processing unit and transmits the measuring result to the display unit.

In an embodiment, the inner surface of the clamp-type measuring head 1 is further provided with an optical sensor, and the principle of the optical sensor for monitoring the current intensity of the cable in real time is mainly based on faraday magneto-optical effect. The faraday magneto-optical effect is that when linearly polarized light passes through a magneto-optical medium placed in a magnetic field, the polarization direction is rotated by an angle proportional to the strength of the magnetic field. Thus, by measuring the rotation angle of polarized light after passing through the magnetic field, the magnetic field strength, i.e. the current strength in the cable, can be measured indirectly. The specific implementation steps are as follows:
first, linearly polarized light is introduced into the cable through the optical system of the optical sensor.
In a cable, a magnetic field is generated by a current passing through a wire, which magnetic field rotates the polarization direction of linearly polarized light.
The rotated linearly polarized light is guided out through an optical system of the optical sensor and transmitted to the detector.
The detector detects the outgoing light and calculates the angle of rotation of the polarization direction by the signal processing unit of the optical sensor.
According to the principle of Faraday magneto-optical effect, the angle of rotation of the polarization direction is proportional to the magnetic field strength, so that the magnetic field strength, i.e. the current strength in the cable, can be measured indirectly.
And finally, transmitting the measured current intensity data to a display unit for display, and simultaneously storing and exporting the data.
Through the steps, the optical sensor can monitor the current intensity of the cable in real time, and provides important reference information for maintenance and management of a communication power supply.
