[0002] As industrial equipment becomes increasingly sophisticated, the requirements for the accuracy of current and voltage parameters in circuits are becoming more stringent, necessitating the deployment of more and more instrument transformers (ETVs) in circuits. Instrument transformers are commonly used devices in electrical systems, converting large current signals into smaller current signals or high voltage signals into low voltage signals for measurement or protection systems. However, existing instrument transformers cannot be resized to meet specific needs, making installation inconvenient and significantly impacting equipment size control. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a volume-adjustable combined current transformer with a simple structure and adjustable volume.

[0004] To achieve the above objectives, this utility model proposes a volume-adjustable combined current transformer, including a left component, a right component, and a first connector threadedly connecting the left and right components. The left component includes a left housing and a left iron core installed inside the left housing. The left iron core is U-shaped and has sliders extending out of the left housing at both ends. A left channel is provided between the sliders on the front and rear sides. The right component includes a right housing and a right iron core installed inside the right housing. The right iron core is U-shaped and has slides penetrating the right housing at both ends. A right channel is provided between the slides on the front and rear sides.

[0005] Preferably, the top side of the slider is provided with a flange to form a T-shape, and the cross-section of the slide is adapted to the slider.

[0006] Preferably, the left side of the top surface of the left housing is provided with a first protrusion and a first through hole, and the left side of the right housing is provided with a first threaded hole corresponding to the first through hole. The first connector includes a first bolt and a first nut. The first bolt passes through the first through hole and is screwed into the first threaded hole. The first nut is threadedly fixed on the first bolt and located between the first protrusion and the right housing.

[0007] Preferably, a second connector is also included. The right side of the bottom surface of the right housing is provided with a second protrusion and a second through hole. The right side of the left housing is provided with a second threaded hole corresponding to the second through hole. The second connector includes a second bolt and a second nut. The second bolt passes through the second through hole and is screwed into the second threaded hole. The second nut is threadedly fixed on the second bolt and located between the second protrusion and the left housing.

[0008] Preferably, the height of the first protrusion is the same as that of the right housing, and the height of the second protrusion is the same as that of the left housing.

[0009] The beneficial effects of this utility model are as follows: By setting sliders and slide rails on the left and right iron cores respectively, the sliders can slide within the slide rails and be connected by threads through connecting parts as needed, thereby adjusting the relative positions of the left and right components and changing the volume occupied by the current transformer; by setting a flange on the side of the top of the slider to form a T-shape, the slider is prevented from slipping off; by setting a first connecting part and a second connecting part, the left and right components are threadedly connected on the top and bottom surfaces respectively, resulting in a tight and firm connection.
