Release: Weikewei Technology

Generally speaking, the mainstream nowadaysOpen type Hall current sensorThe use of can expand the range of communication instruments,Open type Hall current sensors are made according to the principle of transformers, and they have a certain current ratio. As electricity users, 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. The current sensing technology based on current transformers is mainly used in power grids due to its high current measurement capability. Few clamp meters also use current transformers to measure alternating current.

Secondly, we know開口型霍爾電流傳感器It can isolate high currents and improve user safety,We use an open-ended Hall current sensor 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.

The use of open-ended Hall current sensors 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.
