[0034] Reference Figure 1 As shown, a device for continuously detecting high voltage on-line cores of transposed conductors in an embodiment of the present invention comprises:

[0035] Guide mechanism 1, used for guiding the movement of the transposed conductor core;

[0036] A first detection mechanism 2a includes first detection guide roller assemblies 21a disposed on opposite sides of the transposed conductor core along a first direction, wherein the transposed conductor core maintains contact with the first detection guide roller assemblies 21a during movement;

[0037] A second detection mechanism 2b is disposed on one side of the first detection mechanism 2a along the length direction of the transposed wire core, the second detection mechanism 2b including second detection guide roller assemblies 21b disposed on opposite sides of the transposed wire core along a second direction, the transposed wire core maintaining contact with the second detection guide roller assemblies 21b during movement; the first direction, the second direction, and the transposed wire core are perpendicular to each other;

[0038] The control device 3 is respectively connected to the first detection mechanism 2a and the second detection mechanism 2b, and the control device 3 is used to output a high-frequency voltage to the first detection guide roller assembly 21a and the second detection guide roller assembly 21b; wherein, when the insulating paint layer on the surface of the transposed conductor core is damaged, the current can flow into the transposed conductor core through the first detection guide roller assembly 21a and / or the second detection guide roller assembly 21b.

[0039] It should be noted that the first direction and the second direction may be the up, down, left, and right directions of the transposed wire core.

[0040] In one embodiment, a detection box body 4 is further included, wherein the first detection mechanism 2a and the second detection mechanism 2b are both arranged in the detection box body 4, and the detection box body 4 is provided with an opening for the transposed wire core to pass through.

[0041] In one embodiment, the guide mechanism 1 is connected to the production line of the transposed wire core. The guide mechanism 1 includes a detection platform 11 and at least one wire guide roller 12 disposed on the detection platform 11 and located on both sides of the detection box 4 for supporting the transposed wire core.

[0042] In one embodiment, the first detection guide roller assembly 21a and / or the second detection guide roller assembly 21b include a base 21 arranged on the side wall of the detection box body 4, a swing arm 22, a torsion spring arranged between the base 21 and the swing arm 22, and a detection roller 23 rotatably connected to the swing arm 22, the torsion spring is used to provide a force for the detection roller 23 to rotate toward the transposed wire core, the detection rollers 23 of the two first detection guide roller assemblies 21a are respectively arranged in parallel, and the detection rollers 23 of the two second detection guide roller assemblies 21b are respectively arranged in parallel.

[0043] Specifically, the base 21 , the swing arm 22 and the detection roller 23 are all made of conductors.

[0044] The detection roller 23 is made of metal, and its contact surface with the transposed conductor core is a smooth and flat surface. The swing arm 22 provides a constant pressure torque through the torsion spring, so that the detection roller 23 is tightly attached to the surface of the transposed conductor core, thereby realizing continuous contact detection on the four sides of the transposed conductor core, avoiding potential product hazards caused by problems such as foreign matter mixing into the equipment or scratches.

[0045] In one embodiment, the detection box body 4 includes a first connecting plate 41 and a second connecting plate 42 that are rotatably connected. The first connecting plate 41 and the second connecting plate 42 are both L-shaped. A first detection guide roller assembly 21a and a second detection guide roller assembly 21b are respectively disposed on two perpendicular side walls of the first connecting plate 41 and the second connecting plate 42. Four bases 21 can be fixed to the four inner side walls of the detection box body 4 using screws.

[0046] With the above arrangement, the first connecting plate 41 and the second connecting plate 42 can be opened and closed up and down. When the detection box body 4 is closed, the four detection guide rollers of the first detection mechanism 2a and the second detection mechanism 2b are closed together in pairs.

[0047] In one embodiment, the control device 3 is connected to the first connecting plate 41 and the second connecting plate 42 via a wire, and both the first connecting plate 41 and the second connecting plate 42 are made of metal. The detection voltage output by the detection device can be transmitted to the detection roller 23 via the wire, the detection box 4, the base 21, and the swing arm 22.

[0048] In one embodiment, to facilitate observation and threading, and improve operational efficiency, the first connecting plate 41 is placed on a horizontal surface (detection platform 11) and is made of a conductive material, and the second connecting plate 42 can be opened upward, and the two vertical side walls of the second connecting plate 42 are made of a transparent material.

[0049] Specifically, a metal damping hinge 43 is connected between the first connecting plate 41 and the second connecting plate 42, and the damping hinge 43 is in contact with the base 21 close to one side thereof and arranged on the second connecting plate 42, such as by a screw on the damping hinge 43 passing through the transparent second connecting plate 42 and connected to the base 21; a conductor bar is connected between the two vertical side walls of the second connecting plate 42, and the conductor bar is in contact with the two bases 21 on the second connecting plate 42.

[0050] The control device 3 is connected to the damping hinge 43 via a wire.

[0051] Therefore, the detection voltage output by the detection device can be transmitted to the detection roller 23 through the wire, the damping hinge 43 , the detection box body 4 , the base 21 , and the swing arm 22 .

[0052] In one embodiment, the control device 3 includes an alarm module 31, which is capable of generating an alarm when current flows through the first detection guide roller assembly 21a and / or the second detection guide roller assembly 21b to the transposed conductor core. The control device 3 outputs a detection voltage, which is transmitted via wires to the detection rollers 23. The transposed conductor core passes through the centers of the four detection rollers 23. When the surface paint film is damaged, the detection device issues an alarm, and an alarm light illuminates, thereby achieving continuous online detection of the surface paint film quality of the transposed conductor core.

[0053] Specifically, the detection device adopts an ST series high-frequency spark machine (with an integrated alarm light).

[0054] This utility model is based on the principle of high-voltage spark detection. Taking into account the characteristics of transposed conductor cores, such as multiple conductors and the presence of gaps and uneven surfaces, the detection roller 23 can be a smooth metal roller. The control device 3 adjusts the output of high-frequency high voltage and transmits it to the detection roller 23 via the high-voltage conductor. The detection roller 23 is tightly attached to the transposed conductor core and is separated from the transposed conductor core by an insulating lacquer layer, thus forming a capacitor. When the insulating lacquer layer is damaged, current flows from the detection roller to the transposed conductor core, causing instantaneous voltage changes and current fluctuations. The control device 3 detects this and issues an alarm (via the high-frequency spark generator's alarm light).

[0055] When using the transposed conductor core high-voltage continuous online testing device of the present invention, first open the testing box 4, then move the testing platform 11 to the production line of the transposed conductor core. Next, close the testing box and adjust the position of the testing platform 11 so that the transposed conductor core is located in the center of the four testing guides, ensuring that the testing guides and the transposed conductor core are tightly attached.

[0056] Turn on the power switch of the control device 3 and set and adjust the output voltage. At this time, the voltage is transmitted to the detection roller 23 through the wire, and the detection device begins to detect the insulating paint layer on the surface of the wire core.

[0057] During the inspection process, if the surface of the transposed conductor core is damaged and the damaged point contacts the inspection roller 23, current will flow from the inspection roller 23 to the transposed conductor core. The control device 3 can quickly detect this current change, record it, and simultaneously issue an alarm signal to trigger a shutdown operation.

[0058] At this point, production personnel can determine the location of the damage point based on the alarm signal, and inspect and handle it to ensure the continuation of production and the qualification of the product.

[0059] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
