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使我們能夠被動地測量電流，而不會以任何方式中斷電路。它們被放置在我們要測量的導體周圍。

Current transformer在許多應用中是必不可少的。例如，它們通常用于分計量，以確定獨立租戶的能源使用情況。它們還可以通過提供有關能源使用量和時間的信息來幫助設施監管，以降低成本和提率。

電焊機霍爾sensor如何工作？

當電流流過導體時，它在導體周圍產生一個成比例的磁場。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電焊機霍爾傳感器。

電流互感器可以升壓、降壓或保持電流不變。升壓或降壓電流的傳感器通常稱為變壓器。傳感器通常由兩個線圈組成。電流流過的線圈稱為初級繞組，感應電壓的線圈稱為次級繞組。對于我們在vicorv.com銷售的許多電流互感器，安裝CT的導體用作一次繞組，二次繞組位于互感器內。二次繞組纏繞的磁芯取決于傳感器的設計處理方式。變壓器的匝數比是二次繞組的匝數除以一次繞組的匝數。這個比率決定了變壓器是升高電壓還是降低電壓。二次電壓與一次電壓之比等于匝數比，如等式所示。因此，當二次繞組上的匝數大于一次繞組上的匝數時，二次繞組上的電壓較高，是升壓變壓器。電流則相反，次級電流與初級電流之比等于匝數比的倒數。
