Start-stop Sensor
Shanghai Metal Corporation is a leading automatic water supply Start-stop sensor manufacturer and supplier.
The sensor uses the method of measuring the magnetic field to indirectly measure the working state of the equipment. A magnetic field must be generated around the energized conductor, and whether there is a magnetic field around the cable is detected, that is, whether there is current passing through the cable, and the on/off status of the equipment can be identified. The underground electromechanical equipment is three-phase power supply. The three-phase core wire in the cable is divided into symmetrical and asymmetrical. On the cable sheath, there is always a point that is not equidistant from the three-phase core wire. The magnetic field formed by this point is close to The core wire plays a leading role. Using the detection coil in the sensor head, close to the one-phase core wire in the cable, the weak magnetic induction signal can be measured. The greater the power supply current, the stronger the induction signal. The sensed signal is amplified, detected, and converted, and then output, and the equipment start/stop information is transmitted to the information substation, and then transmitted to the ground from the substation.
