Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a mounting structure for a current transformer of a ring network cabinet. Background Art

[0002] A ring main unit is a group of electrical equipment installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises, and current transformers are indispensable internal components in ring main units.

[0003] A current transformer is an instrument that converts a large primary current into a small secondary current for measurement based on the principle of electromagnetic induction. 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.

[0004] In the prior art, when installing a current transformer inside a ring main unit, it is mostly fixed inside the ring main unit by bolts, so that the direction of the current transformer after installation is fixed. When adjusting the installation direction of the current transformer, the installer needs to remove the bolts, which is cumbersome and affects the assembler of the ring main unit.
