Embodiment Construction
[0064] Optical current transformer system embodiment
[0065] This embodiment provides an optical current transformer system, including two current detection devices, one is an optical current transformer. This embodiment takes a representative optical current transformer as an example. Of course, other types of optical current transformers can also be used. Current Transformer, figure 1 It is a schematic diagram of the detection principle of an optical fiber current transformer, such as figure 2 As shown, each fiber optic current transformer has multiple simulated optical breaks; the other is a current detection module. Of course, the two current detection devices detect the current signal of the same line, so that the following current signal replacement mechanism can be realized. Among them, the current detection module is a conventional current detection device, such as a conventional current transformer, which can be specifically an internal LPCT part (low power coil)....
