Description

Technical Field

[0001] The utility model relates to the relevant field of Hall voltage sensors, in particular to a Hall voltage sensor. Background Art

[0002] The Hall voltage sensor is an electronic sensor that uses the Hall effect to pass the primary voltage through an external or built-in resistor to limit the current to 10mA. After this current passes through multiple turns of windings, it passes through the magnetic concentrating material to generate a magnetic field that is detected by the Hall element in the air gap and induces a corresponding electromotive force. This electromotive force is adjusted by the circuit and fed back to the compensation coil for compensation. The magnetic flux generated by the compensation coil is equal to the magnetic flux generated by the primary current in magnitude and opposite in direction, thereby keeping the magnetic flux in the magnetic core at zero. In fact, the Hall voltage sensor uses the same technology as the magnetic balance closed-loop Hall current sensor, that is, the zero flux Hall current sensor.

[0003] There are still certain deficiencies in the use of Hall voltage sensors in the prior art. The wiring position of traditional Hall voltage sensors generally does not have a cable fixing mechanism, and the cables are usually hung outside. After long-term use, the wiring position will become loose, resulting in poor contact. In addition, the shell of the Hall voltage sensor is usually an integrated structure, and the internal heat is not easy to dissipate to the outside, causing the shell to overheat and affecting the service life.
