[0023] The following further describes in detail the embodiments of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0024] Embodiment:

[0025] As Figures 1 to 5As shown in the figure, the present utility model provides a blade-type current transformer. The device includes a main body housing 11 and a cover plate 21. The cover plate 21 is connected to the main body housing 11 to form a relatively airtight and structurally compact installation cavity. Through grooves are provided on both the main body housing 11 and the cover plate 21, and a winding column 31 is passed through the through grooves. An induction coil 22 is installed in the installation cavity, and the induction coil 22 is sleeved on the winding column 31. This not only makes full use of the limited space but also optimizes the layout of the internal structure to the greatest extent. Multiple groups of reinforcing ribs 12 and reinforcing ribs 13 are provided inside the main body housing 11. The reinforcing ribs 12 and the reinforcing ribs 13 enhance the structural strength and stability of the entire main body housing 11, ensuring that the main body housing 11 is not easily deformed or damaged and providing protection for the key components inside. A wire groove 32 is provided on the winding column 31, and a fixing component is arranged in the wire groove 32. The wire is passed through the fixing component. The fixing component can effectively stabilize the wire, enabling it to maintain a stable position and state under various complex working conditions. Two groups of pins 14 are also provided on the main body housing 11. The induction coil 22 is respectively connected to these two groups of pins 14, ensuring that the electrical signals generated by the induction coil 22 can be accurately transmitted to the external circuit through the pins 14, providing a strong guarantee for the normal operation and measurement of the entire system.

[0026] The fixing component includes two groups of fixing plates 41. Multiple groups of connecting plates 33 are arranged inside the wire groove 32. The fixing plates 41 are located between two of the connecting plates 33. One end of the fixing plate 41 is provided with a slider 42, and the other end is detachably provided with a limiting bolt 43. A sliding groove 34 is also provided on the connecting plate 33. The slider 42 and the limiting bolt 43 are respectively clamped in the corresponding sliding grooves 34, enabling a sliding connection between the fixing plate 41 and the winding column 31.

[0027] Convex blocks 44 are provided on the corresponding surfaces of the fixing plate 41 and the winding column 31. Multiple groups of limiting holes 45 are provided on the convex blocks 44. Multiple groups of first springs are arranged between the fixing plate 41 and the winding column 31. The two ends of the first spring are respectively clamped in the corresponding limiting holes 45. The first spring endows the fixing plate 41 with a certain elastic telescopic ability, enabling the fixing plate 41 to adjust its position according to actual needs during the sliding process and maintaining a stable state after adjustment.

[0028] A rubber pad 46 is arranged on the inner side of the fixing plate 41. The wire is clamped between the two fixing plates 41, and the rubber pad 46 is in direct contact with the wire, which can effectively increase the friction with the wire, thereby further improving the fixing effect on the wire. At the same time, the rubber pad 46 can also play a role in buffering and protecting the wire, avoiding excessive extrusion and wear of the wire during the fixing process.

[0029] When the wire is placed between two sets of fixed plates 41, the elastic force of the first spring causes the fixed plates 41 to approach each other, thereby tightly clamping the wire. The rubber pad 46 not only increases the friction force but also can adapt to wires of different thicknesses, providing a more secure and stable fixation.

[0030] On one side of the main body housing 11, multiple sets of connecting studs 15 are provided. Corresponding to these connecting studs 15, the winding column 31 is provided with connecting holes. The connecting studs 15 pass through the connecting holes and are sleeved with nuts, realizing a detachable connection method between the winding column 31 and the main body housing 11. When maintenance, replacement, or adjustment of the winding column 31 is required, the nut can be easily unscrewed to disassemble the winding column 31 from the main body housing 11, with simple and quick operation. Multiple sets of card slots 35 are also provided on the winding column 31, and the clamping blocks 36 are clamped in the card slots 35. A second spring is provided in the card slots 35. The clamping blocks 36 are connected to the winding column 31 through the second spring. The mutual inductance coil 22 is located between the two clamping blocks 36 and the main body housing 11, and the clamping blocks 36 are clamped on the mutual inductance coil 22, effectively playing a role in limiting and fixing the mutual inductance coil 22. On one side of the cover plate 21, multiple sets of installation buckles 23 are provided, and the main body housing 11 is provided with installation card slots 16 corresponding to the installation buckles 23. The installation buckles 23 can be clamped in the installation card slots 16, thereby realizing a detachable connection between the cover plate 21 and the main body housing 11. This not only facilitates the assembly and disassembly of the device but also enables the cover plate 21 to be quickly opened during maintenance and repair, improving work efficiency.

[0031] In addition, insulating coatings are applied to both the main body housing 11 and the cover plate 21. The insulating coating is made of polyester resin. Polyester resin has excellent insulation performance, corrosion resistance, and wear resistance. The insulating coating applied to the surfaces of the main body housing 11 and the cover plate 21 can effectively prevent current leakage, ensuring the safety of the device and the operator. At the same time, this coating can also protect the main body housing 11 and the cover plate 21 from being eroded by the external environment, extending the service life of the device.

[0032] The specific usage method and function of this embodiment:

[0033] In use, correctly connect the pin 14 of the mutual inductor to the external circuit, paying attention to the accuracy and firmness of the connection to ensure the accurate transmission of electrical signals. Pass the wire to be measured through the fixing component in the wire slot 32 on the winding post 31, place the wire between the two sets of fixing plates 41, and the elastic force of the first spring will cause the fixing plates 41 to approach each other and tightly clamp the wire. The rubber pad 46 is in full contact with the wire to increase friction and provide buffer protection. When installing the mutual inductance coil 22, sleuth it on the winding post 31, located between the two sets of clamping blocks 36 and the main body housing 11. The clamping blocks 36 will limit and fix the mutual inductance coil 22 under the action of the second spring. If maintenance, replacement or adjustment of the winding post 31 is required, simply unscrew the nut on the connecting stud 15 to easily disassemble it. When it is necessary to open the device for internal inspection or maintenance, just disengage the installation buckle 23 on one side of the cover plate 21 from the installation slot 16 of the main body housing 11 to quickly open the cover plate 21. During the operation of the device, the polyester resin insulation coatings on the main body housing 11 and the cover plate 21 can effectively ensure the safety of the device and the operator and prevent the device from being eroded by the external environment.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
