A current transformer consists of a closed iron core and a winding. Its primary winding has very few turns and is connected in series in the circuit of the current that needs to be measured.

[0003] The existing combined current transformer is generally fixed by screws during installation. If the staff frequently replaces and repairs the combined current transformer, it is easy to cause the problem of thread slippage at the installation position, while reducing the fixity of the combined current transformer installation. In addition, during the process of disassembling and assembling the combined current transformer, the staff also needs to use other tools, resulting in the combined current transformer disassembly and assembly process not being fast enough.

The positioning component includes a fixed plate, a spring, a sliding plate, a limit plate and a trigger plate. The rear end of the trigger plate passes through the rear side wall of the support box from the inside of the support box. The rear side wall of the support box is provided with a long hole corresponding to the trigger plate. The right end of the sliding plate is fixedly connected to two positioning shafts. The current transformer body is provided with multiple positioning holes corresponding to the positioning shafts are provided at the left end of each current transformer body.
