Description

Technical Field

[0001] The utility model relates to the technical field of current transformers, in particular to a current transformer with a wiring cable. Background Art

[0002] A current transformer is composed of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current to be measured passes through. Therefore, it often has the full current of the circuit flowing through it. The secondary winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series-connected coil in the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit.

[0003] However, in the prior art, when the existing current transformer detects the current circuit, it cannot fix it, nor can it be adjusted according to the thickness of the circuit, which is not conducive to actual application and operation. In view of the above problems, we have developed a current transformer with a wiring cable. Summary of the Utility Model

[0013] By setting, by using a tool to rotate the nuts, the nuts can drive the screws to rotate.

[0014] In a preferred embodiment, a turntable is rotatably connected to the outer side of the fixed ring. The turntable is fixedly connected to one of the rotating shafts. Through grooves are formed on the outer side of the fixed ring and on the outer side of the sliding rod.

[0015] By setting, by rotating the turntable, one of the rotating shafts can be driven to rotate, so that the second gear drives the rotating ring to rotate.

[0016] In a preferred embodiment, rubber blocks are fixedly connected to the inner wall of the clamping block at equal intervals. A base is fixedly connected to the bottom of the current transformer. Slide holes are formed at the four corners of the top of the base. Fixing holes are formed at the four corners of the bottom of the base and below the slide holes.

[0017] By setting, by putting bolts into the slide holes and fixing them through the fixing holes.
