Where to buy Weikewei 380 Hall current sensor for welding machine

Release: Weikewei Technology

Generally speaking, the mainstream nowadaysWelding machine 380 Hall current sensorThe use of can expand the range of communication instruments,The 380 Hall current sensor of the welding machine is made according to the principle of a transformer, and it has a certain current ratio. As an electricity user, we need to choose according to the amount of electricity used. If it is a major electricity consumer, such as factories, mines, and enterprises, it is necessary100AThe current we currently use, both single-phase and three-phase meters, cannot accommodate such a large current. Therefore, we need to choose a current transformer to proportionally convert the large current into a small current, and then measure it with a low range instrument. This is equivalent to expanding the range of the AC meter. Flux gate sensors are used in solar inverters to induce current. In addition, closed-loop AC and DC current measurement can be easily accomplished using flux gate sensors. The flux gate current sensing method can also be used for leakage current measurement, overcurrent detection, etc.

Secondly, we know电焊机380 霍尔电流传感器It can isolate high currents and improve user safety,We use a 380 Hall current sensor with an electric welding machine to convert high current into low current. From the structure of the current transformer, we can see that there is no direct electrical connection between its primary and secondary sides. They are only coupled by a magnetic circuit. When measuring high current, the primary side of the current transformer is directly connected to the measuring circuit, while the secondary side is connected to the AC instrument, which has no direct electrical relationship with the measured circuit. In this way, the measured AC instrument and operator are separated from the high-voltage electricity, thus protecting personal safety and instrument safety.

Using a welding machine with a 380 Hall current sensor can reduce production costs and standardize the production of instrumentsThe third function of current transformers is to promote standardization in instrument production. We know that the current on the secondary side of current transformers is uniformly made into a standard5ATherefore, as long as the production range is5AJust use an AC ammeter, and then equip different current transformers according to different current levels. This not only reduces production costs but also standardizes instruments, killing two birds with one stone, which is very good.
