[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] Please see attached Figure 1-2 The present application provides an online monitoring device for transformer core clamps, which includes a monitoring device body 1 and multiple through-type current transformers 2. The through-type current transformers 2 are electrically connected to the monitoring device body 1. The through-type current transformers 2 include a transformer body 3 and a mounting seat 4. The mounting seat has a plurality of first mounting holes 5 and a plurality of connecting plates 6 extending forward. A connecting hole for plugging with the connecting plate is provided on the base 31 of the transformer body 3. The transformer body can slide back and forth along the connecting plate in cooperation with the connecting hole and the connecting plate. A fastener 7 for fixing the transformer body 3 at any position of the connecting plate 6 is provided on the base 31. After the transformer body slides to a suitable position, it is fastened by the fastener to fix the transformer body at the current position of the connecting plate.

[0015] The fastener 7 is a fastening screw, and a screw hole for the fastening screw is opened on the base 31. The stud of the fastening screw faces the connecting plate 6. When it is necessary to slide the transformer body, the fastening screw is loosened, and after sliding to a suitable position, the fastening screw is tightened. The operation is very convenient.

[0016] The connection holes on the base 31 are arranged at the corners of the transformer body 3. When viewed from above, the connection plate 6 and the sensing hole 32 on the transformer body do not interfere with each other. This structure can avoid interference between the connection plate and the sensing hole and does not affect the sliding of the transformer body.

[0017] The cross section of the connecting plate 6 is rectangular, and arc-shaped transition structures 61 are provided at the ends and edges of the connecting plate, so that the connecting plate can easily pass through the connecting hole and the transformer body can slide smoothly on the connecting plate.

[0018] The upper end face and / or lower end face of the mounting seat 4 is provided with a top plate 8, which is perpendicular to the mounting seat, and has a second mounting hole 9. The left end face and / or right end face of the mounting seat 4 is provided with a side plate 10, which is perpendicular to the mounting seat, and has a third mounting hole 11. During installation, the mounting seat can be more adaptable to installation, and can be installed and fixed in different orientation angles, thereby improving the versatility and applicability of the product.
