Analysis and improvement of split core current transformer

  Split core current transformer, as its name implies, is a current transformer that can be opened and closed on the primary circuit (the side of the measured current circuit, usually a cable or parent card), and is a secondary device by sensing the current on the primary circuit Take measurements or protect relays.

    In recent years, although the development of China’s distribution network has improved significantly, the development of urban and rural areas is uneven, and the quality of electricity needs to be improved. At the same time, the country has continuously put forward requirements for energy management. In such a general environment, we urgently need In the second transformation, the current transformer is needed to measure or protect the line in the transformation project, but the ordinary current transformer is a completely enclosed structure  because this current transformer is a closed loop The structure, so the line must be disassembled once in use, and the line must be disassembled again, and the power must be cut off.

   If the power is cut off for a few days or even half a month for the purpose of transformation, it will be difficult for some shopping malls, supermarkets, The loss of the enterprise is very large. So clamp on current transformer came into being. The feature of split core sensor current transformer is: the primary side of the current transformer is an clamp on or split on structure. Material and financial resources, and greatly improved efficiency.
