Description

Technical field [0001] The present invention relates to a connecting device, and more specifically to a power adapter. Background technique [0002] Current transformers are widely used in various power equipment, and are mainly used for current conversion to achieve the purpose of detecting large currents. [0003] The current transformer structure is basically the structure of iron core and winding, so in the process of energization induction, the magnetic field is induced through the primary winding and then transferred to the secondary winding through the magnetic field of the iron core, and then through the secondary winding. The secondary winding induces the converted current output. Therefore, during the working process of the current transformer, it must be operated in a short-circuit state, otherwise high voltage will be generated on the terminals of the current transformer, which will easily cause safety accidents. The connection between the current transformer and the d...

Problems solved by technology

[0003] The structure of the existing current transformer is basically the structure of iron core and winding. Therefore, in the process of electrification induction, the magnetic field is induced through the primary winding and then passed to the secondary winding through the magnetic field of the iron core, and then passed through the secondary winding. The secondary winding induces the converted current output, so in the working process of the current transformer, it must be operated in a short-circuit state, otherwise a high voltage will be generated on the terminals of the current transformer, which will easily cause a safety accident, while the existing The connection between the current transformer and the detection equipment is realized by the cooperation between the cable and the adapter. If the current transformer is powered on during the wiring process, the current transformer needs to be connected every time it is disassembled. It is very troublesome if the transformer is short-circuited and then not short-circuited, and it is easy to cause safety accidents caused by forgetting to short-circuit the current transformer
