DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Please refer to Figures 1-4, the present utility model provides an electronic device based on induction current detection, including: a device panel 1, mounting posts 2, a pressing plate 3, and a display device 5. Two groups of mounting posts 2 are arranged at intervals on the device panel 1, a pressing plate 3 is arranged between each mounting post 2, and a detection device 4 is sleeved on the pressing plate 3;

[0035] One end of the pressing plate 3 is rotatably arranged on one of the mounting posts 2, the other end of the pressing plate 3 is clamped on the other mounting post 2, and two limiting holes 31 are arranged at intervals along the width direction at one end of the pressing plate 3 close to its rotation axis;

[0036] The detection device 4 includes an induction component 41 and a positioning component 42. The induction component 41 is used to inductively detect the instantaneous current generated when the pressing plate 3 is closed, and the positioning component 42 is used to lock the position of the detection device 4 on the pressing plate 3;

[0037] The display device 5 is arranged on the device panel 1 on the rotation side of the pressing plate 3. The display device 5 is connected to the induction component 41 through a wire 6, and the display device 5 is used to display the instantaneous current when the pressing plate 3 is closed.

[0038] It should be explained that the wire 6 is in a spiral structure and can be stretched to a certain extent, which is convenient for the rotation and opening / closing of the pressing plate 3. The display device 5 is externally powered.

[0039] The device panel 1 is an operation panel of a substation protection or control device. When in use, first install the display device 5 on the rotation side of the pressing plate 3 on the device panel 1, then sleeve the detection device 4 on the pressing plate 3 and lock it. Finally, the staff rotates the pressing plate 3 to engage with the mounting post 2 to conduct the circuit. The detection device 4 uses the electromagnetic induction principle to detect the instantaneous current generated at the moment when the pressing plate 3 is closed, and the display device 5 displays the value, which is convenient, intuitive, and fast to detect the instantaneous current when the pressing plate is closed, and improves the detection efficiency of the instantaneous current when the pressing plate 3 is closed.

[0040] In this embodiment, the induction component 41 includes:

[0041] An induction housing 411, the induction housing 411 is slidably sleeved on the pressing plate 3. An outer step 412 is provided on the outer peripheral side of one end of the induction housing 411 close to the rotation axis of the pressing plate 3, and a rectangular ring cavity 413 is provided on the inner peripheral side of the induction housing 411 at one end of the outer step 412;

[0042] An induction coil 414 is spirally adhered along the inner wall of the rectangular ring cavity 413;

[0043] An outlet is provided on one side of the outer step 412 close to the display device 5.

[0044] The induction coil 414 is connected to the display device 5 via a wire 6 .

[0045] In this embodiment, the positioning component 42 includes:

[0046] A positioning housing 421, wherein the positioning housing 421 is slidably sleeved on the pressing plate 3, and an inner step 422 is correspondingly provided on the inner circumference of one end of the positioning housing 421 close to the sensing housing 411, and the inner step 422 is inserted into the outer step 412;

[0047] The positioning housing 421 is located at the top of the rear end of the inner step 422 and is elevated, and a cylindrical cavity 424 is formed through the elevated portion along its length direction, and a second limiting hole is formed just above the cylindrical cavity 424 and vertically downwardly through the internal sliding cavity of the positioning housing 421. The second limiting hole is arranged corresponding to the first limiting hole 31, and a limiting countersunk hole is provided at the upper end of the second limiting hole;

[0048] A T-shaped limiting block 423 is slidably inserted into the second limiting hole, and the limiting counterbore is used to limit the lateral part of the T-shaped limiting block 423 .

[0049] The sensing housing 411 and the positioning housing 421 are both made of insulating materials.

[0050] It should be explained that when the detection device 4 is dragged and moved along the pressure plate 3 outside the limit hole 31, the T-shaped limit block 423 protrudes from the top of the positioning shell 421. When the detection device 4 is dragged and moved along the pressure plate 3 to the limit hole 31, the T-shaped limit block 423 enters the limit hole 31 to lock the detection device 4. At this time, the top of the T-shaped limit block 423 coincides with the top of the positioning shell 421, which can be used as a basis for judging whether the detection device 4 is locked, avoiding the movement of the detection device 4 during detection and affecting the accuracy of the detection data. In addition, by using the plug-in method to set the sensing component 41 and the locking component 42 in the detection device 4, the components are modularly arranged, which is convenient for rapid replacement of damaged modules at a later stage.

[0051] In this embodiment, threaded holes are formed at both ends of the cylindrical cavity 424, and the threaded holes at both ends are threadedly connected to limit sleeves 427;

[0052] Slide rods 425 are slidably disposed in the limit sleeves 427 at both ends, and one end of the slide rod 425 located in the cylindrical cavity 424 is a conical structure, and a retaining ring 426 is fixed at the transition between the conical part and the cylindrical part of the slide rod 425 at both ends, and the retaining ring 426 is slidably matched with the cylindrical cavity 424;

[0053] The retaining ring 426 is elastically connected to the inner end surface of the limiting sleeve 427 via a spring 428;

[0054] A vertical portion of the T-shaped limit block 423 is provided with an adjustment hole 4231 penetrating toward one side of the slide bar 425, and the adjustment hole 4231 has the same diameter as the slide bar 425.

[0055] Wherein, when the T-shaped limit block 423 is inserted into the first limit hole 31 to the limit position to lock the detection device 4, the tip of the conical structure is located at the upper limit position inside the adjustment hole 4231, and can limit the T-shaped limit block 423 from sliding out.

[0056] In the initial state, the spring 428 is in an unloaded state. At this time, if the detection device 4 is in an unlocked state, the slide bar 425 is coaxial with the adjustment hole. If the detection device 4 is in a locked state, the tip of the conical structure of the slide bar 425 is located at the upper limit position inside the adjustment hole 4231. When it is necessary to unlock the detection device 4, by pressing the two side pressing blocks 429 simultaneously to stretch the spring 428, the conical part of the slide bar 425 is moved inwards to push against the adjustment hole 4231, thereby driving the T-shaped limit block 423 to move upwards and releasing the limit on the detection device 4.

[0057] Specifically, the first limit hole 31 is a blind hole or a through hole.

[0058] In this embodiment, a pressing block 429 is detachably arranged at the outer end of the slide bar 425. On the one hand, it increases the pressing area to facilitate the pressing operation of the staff, and on the other hand, the detachable arrangement facilitates the assembly of the slide bar 425 and the limit sleeve 427.

[0059] In this embodiment, an avoidance opening 4210 is correspondingly provided at the inner step 422 and penetrates through the outlet.

[0060] In this embodiment, a first magnetic strip is adhered to the bottom of the limit counterbore, and a second magnetic strip is arranged at the bottom of the transverse portion of the T-shaped limit block 423, and the first magnetic strip and the second magnetic strip can generate an adsorption effect.

[0061] Wherein, when the T-shaped limit block 423 moves to the first limit hole 31, the first magnetic strip and the second magnetic strip adsorb each other, facilitating the automatic insertion of the T-shaped limit block 423 to lock the detection device 4.

[0062] In this embodiment, an insulating extension 43 is provided at the relative ends of the induction housing 411 and the positioning housing 421, and the extension 43 is sleeved on the pressing plate 3.

[0063] During specific implementation, first install the display device on the rotating side of the pressure plate on the equipment panel, then sleeved the detection device on the pressure plate and lock it. Finally, rotate the pressure plate by the staff to engage with the mounting post to conduct the circuit. The detection device uses the principle of electromagnetic induction to detect the instantaneous current generated at the moment when the pressure plate is closed, and the display device performs numerical display, which is convenient, intuitive and fast to detect the instantaneous current when the pressure plate is closed, and improves the detection efficiency of the instantaneous current when the pressure plate is closed.

[0064] The above are only the preferred specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
