卖来芯-Hall sensor for welding machine-公司-[韦克威]

发布人：韦克威科技

Hall Current Sensor , also commonly known as current transformer or current transformer, is a device that measures the current flowing through a wire by using a magnetic field to detect the current and generate a proportional output. Hall sensor for welding machineWhat is it? They are used together with AC and DC currents. Hall sensor for welding machine使我们能够被动地测量电流，而不会以任何方式中断电路。它们被放置在我们要测量的导体周围。

Current transformer在许多应用中是必不可少的。例如，它们通常用于分计量，以确定独立租户的能源使用情况。它们还可以通过提供有关能源使用量和时间的信息来帮助设施监管，以降低成本和提率。

电焊机霍尔sensor如何工作？

当电流流过导体时，它在导体周围产生一个成比例的磁场。Current transformerUse this magnetic field to measure current. If CT is designed to measure AC current, induction technology is usually used. Alternating current changes the potential, causing the magnetic field to continuously collapse and expand. In an AC current sensor, the wire is wound around the core. The magnetic field generated by the current through the conductor induces a proportional current or voltage in the wire inside the current sensor. Then the sensor outputs a certain voltage or current, which can be read and converted into the amount of current flowing through the conductor by the instrument connected to the sensor. For example, when the current through the conductor is 400A, there can be a current transformer that outputs 333mV (333mV is the common output of CT). Once you configure the instrument to read 400A when receiving a 333mV input, it will be able to calculate the amperage flowing through the conductor based on the received input. The working principle of DC current sensors is similar, but the products that rely on Hall effect technology to work are电焊机霍尔传感器。

电流互感器可以升压、降压或保持电流不变。升压或降压电流的传感器通常称为变压器。传感器通常由两个线圈组成。电流流过的线圈称为初级绕组，感应电压的线圈称为次级绕组。对于我们在vicorv.com销售的许多电流互感器，安装CT的导体用作一次绕组，二次绕组位于互感器内。二次绕组缠绕的磁芯取决于传感器的设计处理方式。变压器的匝数比是二次绕组的匝数除以一次绕组的匝数。这个比率决定了变压器是升高电压还是降低电压。二次电压与一次电压之比等于匝数比，如等式所示。因此，当二次绕组上的匝数大于一次绕组上的匝数时，二次绕组上的电压较高，是升压变压器。电流则相反，次级电流与初级电流之比等于匝数比的倒数。
