Description

Technical Field

[0001] The present invention relates to the technical field of electric variable detection, and in particular to a current transformer detection device and a detection method. Background Art

[0002] A current transformer is an instrument used to measure AC current in power systems. Its working principle is similar to that of a transformer, but it is mainly used to measure the current and convert it into a relatively small current signal that is easy to measure.

[0003] In the production process, in order to ensure the quality qualification rate of current transformer production, it is usually necessary to conduct current signal detection test on the current transformer to ensure that the produced current transformer can meet the standard. At present, for the current signal detection of the current transformer, it is usually necessary to wind the matching number of turns of wire according to the information marked on the current transformer for detection, but this method is relatively cumbersome and the detection efficiency is low, so a new current transformer detection device has emerged.

[0004] According to the Chinese invention patent number: CN117741545A, a production and testing device for a current transformer of a power grid accessory is provided, comprising two support platforms for support, an operating panel is fixed to the upper ends of the two support platforms, a driving component is provided on the right side of the upper end of the operating panel, a motor is fixed to the front side of the driving component, a matching component is fixed to the middle of the front side of the upper end of the operating panel, and a clamping component is provided on the rear side of the matching component. The production and testing device for a current transformer of a power grid accessory described in the present invention, through the mutual linkage and cooperation between the driving component, the matching component, the clamping component and the test component, only needs to place the current transformer body on the upper end of the installation plate, and the current transformer body can be tested through the linkage and cooperation between the clamping component, the test component and the matching component, which can save the time of clamping the current clamp or winding the wire, thereby improving the working efficiency of the device.

[0005] In the above patent document, a male socket is passed through the power-on hole of the current transformer and connected with a female socket to realize the circulation and detection of current. However, this method can only simulate the detection of one turn of the wire winding. When it is necessary to simulate the detection of multiple turns of winding, it is necessary to add multiple wires and pass through the power-on hole of the current transformer at the same time. At this time, since the output current is not output from the same wire, it will cause the problem of inaccurate detection data. In addition, since the position where the female socket and the male socket are connected is close to one end of the wire, there will be sufficient current at the detected position of the wire. For actual wire winding detection, the number of turns of the winding is different, the detection position is also different, and the current of the wire will become smaller. Therefore, the accuracy of the current detected by the above technology is low. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the shortcomings of the prior art, the present invention provides a current transformer detection device and detection method, which have the advantages of being able to conveniently detect current transformers without limiting the number of winding turns and being able to improve the accuracy of detection data, thereby solving the problem of low detection data accuracy in the above-mentioned technology.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the present invention provides the following technical solutions: A current transformer detection device, comprising a supporting plate, a placement assembly, a detection assembly, a regulating assembly, a support assembly, a support rod assembly, a cable assembly and a retaining assembly.

[0010] A placement component is installed on the support plate, and the placement component includes a placement table fixed on the support plate. The placement table is located in the middle of the support plate. The placement table is used to provide a placement space for the current transformer so that the current transformer is in a stable state waiting for subsequent detection operations.

[0011] The placement component also includes two second connection grooves opened on the support plate, and the second connection grooves are away from the side of the placement platform. A detection component for current detection is installed in the second connection groove. The detection component is connected to the positive and negative screws on the current transformer. At the same time, the detection component is connected to the current detection instrument. When the current transformer is powered on, the received current is fed back to the connected current detection instrument through the detection component, so that the current situation can be checked through the current detection instrument.

[0012] Two sets of regulating components are also installed on the support plate, which include a bottom plate slidably connected to the support plate, a base fixed on the bottom plate, a support plate fixed on the base, and a support component movably connected to the support plate. The two sets of regulating components operate synchronously and can approach or move away from the placement platform at the same time. When approaching, the cable assemblies can be docked and separated.

[0013] The support assembly includes a movable plate movably connected to the support plate, a support frame is fixed on the movable plate, a stabilizing sleeve is fixed on the support frame, a support rod assembly is movably connected in the stabilizing sleeve, and the movable plate drives the support frame to move left and right on the support plate to achieve fine-tuning of the position of the cable assembly, so that when the regulating components are close to each other, the cable assemblies can be accurately docked.

[0014] The support rod assembly includes a telescopic rod movably sleeved in the support frame, a connecting rod is fixed at one end of the telescopic rod, a cable assembly is fixed on the connecting rod, the cable assemblies on the two sets of regulating assemblies are connected to each other, and the telescopic rod moves forward and backward to adjust the front and rear positions of the cable assemblies, so that when the regulating assemblies are close to the limit, the cable assemblies can be fully connected.

[0015] The cable assembly includes an arc tube fixed on the side of the connecting rod, a number of wires are sleeved in the arc tube, and sleeve rings are fixed at both ends of the wires. At the same time, clay is filled between the inside of the arc tube and the side of the wires. The arc tube is in a "J" shape. When the two cable assemblies are close to each other, the arc tubes are butt-jointed to form an "O" shape and can be flexibly sleeved on the middle through hole and the outside of the current transformer.

[0016] Two sets of retaining components are also installed on the side of the supporting plate, and the retaining components are used to press the grounding plate at the bottom of the current transformer.

[0017] As a further improvement of the above solution, a slide rail is provided on the support plate along its length direction, a mover is fixed on the bottom plate, the mover passes through the bottom of the bottom plate and is slidably connected to the side of the slide rail.

[0018] Through the above technical solution, two slide rails are arranged in parallel on the support plate, and two movers are also arranged on the bottom plate. The movers are slidably connected to the corresponding slide rails, and the movers in the two groups of regulating components operate synchronously, so that the two groups of regulating components can approach the opposite side or move away from the opposite side at the same time, and the stability of the regulating components is improved, so that the cable assemblies can be fully and accurately docked.

[0019] As a further improvement of the above scheme, two first connecting grooves are opened on the placement table, and the first connecting grooves are equipped with convex strips. The detection component includes a connecting plate, and the connecting plate is movably sleeved in the second connecting groove. At the same time, a linkage plate is fixed at the bottom of the connecting plate, and the bottom of the convex strip is fixed on the linkage plate. A plurality of tension springs are fixed at the bottom of the linkage plate, and the tension springs are fixed in the first connecting groove and the second connecting groove.

[0020] Through the above technical solution, multiple tension springs are evenly distributed at the bottom of the linkage plate to ensure the stability of the linkage plate in rising and falling. Under the push of the tension springs, the convex strip and the connecting plate are driven to move upward at the same time through the linkage plate, so that the convex strip is higher than the upper surface of the placement table.

[0021] As a further improvement of the above solution, two connecting grooves are provided on the connecting plate, and copper sheets are fixed to the inner walls of the connecting grooves.

[0022] Through the above technical solution, the inner side of the connecting groove is covered with a copper sheet, and the connecting plate does not have a conductive function. The copper sheet is connected to the current detector. When the current transformer is placed on the raised convex strip, the positive and negative screws on the side of the current transformer are in the corresponding connecting grooves. The connecting plate is lowered to connect the screws to the copper sheet, so that the current size and whether it is powered on are detected by the connected current detector.

[0023] As a further improvement of the above-mentioned scheme, two stable slide rails are arranged in parallel on the support plate along its length direction, and the bottom of the movable plate is slidably connected to the stable slide rails. At the same time, a limiting slide groove is provided on the support plate between the two stable slide rails, and a connecting piece is fixed on the bottom of the movable plate, and the connecting piece is slidably connected in the limiting slide groove.

[0024] Through the above technical solution, two grooves that match the sides of the stable slide rails are opened at the bottom of the movable plate along its length direction, and the grooves are slidably sleeved on the corresponding stable slide rails to improve the stability of the movement of the support assembly.

[0025] As a further improvement of the above scheme, a mounting panel is vertically fixed to one end of the support plate, a driving motor is fixed on the mounting panel, the output end of the driving motor passes through the mounting panel, a spiral rod is fixed on the output end, one end of the spiral rod is rotatably connected to the corresponding surface of the base, and the connecting piece is threadedly connected to the side of the spiral rod.

[0026] Through the above technical solution, the output end of the driving motor has the function of bidirectional rotation. When the driving motor is operating, the output end drives the spiral rod to rotate. Under the force of the connection between the spiral rod and the internal thread of the connecting part, the support assembly moves left and right to adjust the position of the cable assembly.

[0027] The two sets of regulating components cannot be aligned, and need to be set up one on the left and one on the right so that the cable assemblies on the regulating components can be aligned.

[0028] As a further improvement of the above solution, a rotating gear is rotatably connected in the support frame, a transmission gear is fixed to one end of the rotating gear, and a tooth profile is provided on the side of the telescopic rod, and the transmission gear meshes with the tooth profile.

[0029] Through the above technical solution, the rotating gear drives the transmission gear to rotate, and the telescopic rod moves forward and backward under the force of the engagement between the transmission gear and the tooth profile, and the front and rear positions of the front arc tube are adjusted, so that when a wider current transformer is detected, the arc tubes in the two groups of cable assemblies can be fully connected.

[0030] As a further improvement of the above solution, a transmission motor is fixed to the side of the support frame, the output end of the transmission motor passes through the support frame, and a driving gear is fixed to the output end, and a transmission toothed belt is meshed between the driving gear and the side of the rotating gear.

[0031] Through the above technical solution, the output end of the transmission motor has the function of bidirectional rotation. When the transmission motor is in operation, the output end drives the driving gear to rotate, and through the transmission of the transmission belt, the rotating gear rotates, ultimately achieving the effect of moving the telescopic rod forward and backward to adjust the distance.

[0032] As a further improvement of the above scheme, the retaining assembly includes an auxiliary pressure plate fixed on the side of the base plate, the auxiliary pressure plate is provided with a mounting hole, a spring button is threadedly connected to the mounting hole, and the lower surface of the auxiliary pressure plate is higher than the upper surface of the placement table.

[0033] Through the above technical solution, the output end of the spring button presents a gradually thickening slope from the front end to the end. When the bottom plate approaches the placement table, the output end of the spring button contacts the grounding plate at the bottom of the current transformer lifted by the convex strip. The output end of the spring button is retracted inward, and the pressure generated by the slope causes the current transformer to descend (the convex strip is retracted into the first connecting groove) until the output end of the spring button is completely retracted inside, and the grounding plate is clamped and fixed by the auxiliary pressure plate to prevent the current transformer from loosening during detection.

[0034] A detection method for a current transformer detection device includes the following steps:

[0035] S1: Place the current transformer on the placement table so that the grounding plate at the bottom of the current transformer fits on the two raised ridges and waits for testing. At the same time, the positive and negative screws on the side of the current transformer are in the connecting grooves.

[0036] S2: By controlling the movement of the mover, the two groups of control components are moved closer to the placement table. The connecting rod on one of the control components drives one end of the arc tube to pass through the middle hole of the current transformer, and the connecting rod on the other control component drives the arc tube to move closer to the outside of the current transformer until the two connecting rods are completely parallel. The arc tubes are butted, that is, the internal wires are connected one by one.

[0037] S3: When the regulating component is about to fit the side of the placement table, the retaining component on the side of the bottom plate presses down the grounding plate at the bottom of the current transformer so that the grounding plate is completely fitted on the placement table.

[0038] S4: When the grounding plate is pressed, the convex strip is received in the first connecting groove, and the connecting plate is driven downward by the linkage plate, so that the copper sheet in the connecting groove fits tightly with the screw of the corresponding pole, and the power is turned on through the wire. At the same time, the current detector connected to the detection component detects the current.

[0039] Compared with the prior art, the present invention provides a current transformer detection device and detection method, which have the following beneficial effects:

[0040] 1. The current transformer detection device and detection method are characterized in that an electric wire is installed in an arc tube, the electric wire is wound into multiple turns in a winding shape and then cut into two parts, which are respectively installed in the arc tubes in two groups of cable assemblies, and copper sleeve rings are installed at both ends of the cut wire. When the two groups of control components approach the current transformer in the middle, the cut wires are spliced ​​and connected into a complete multi-turn winding wire, so that the current transformer can be quickly detected and multi-turn winding detection is realized, further improving the accuracy of detection.

[0041] 2. The current transformer detection device and detection method can drive the retaining components to press and fix the placed current transformer by moving two sets of regulating components closer to the middle to achieve the connection of multiple turns of wire windings to form a complete wire. When the fixing operation is completed, the connecting plate is pulled to connect the copper parts with the positive and negative screws of the current transformer to perform current detection and provide a secondary fixing effect.

[0094] S1: Place the current transformer on the placement table 201 so that the grounding plate at the bottom of the current transformer fits on the two raised ridges 204 and waits for detection. Meanwhile, the positive and negative screws on the side of the current transformer are in the connecting grooves 302.

[0095] S2: By controlling the movement device 402 to operate, the two groups of regulating components 4 are moved closer to the placement platform, and the connecting rod 603 on one of the regulating components 4 drives one end of the arc tube 701 to pass through the middle through hole of the current transformer, and the connecting rod 603 on the other regulating component 4 drives the arc tube 701 to move closer to the outside of the current transformer, until the two connecting rods 603 are completely parallel, the arc tubes 701 are butted, that is, the internal wires 702 are butted one by one to form a complete wire 702.

[0096] S3: When the regulating component 4 is about to fit the side of the placement platform 201 , the retaining component 8 on the side of the bottom plate 401 presses the grounding plate at the bottom of the current transformer downward, so that the grounding plate is completely fitted on the placement platform 201 .

[0097] S4: When the grounding plate is pressed, the protrusion 204 is received in the first connecting groove 203, and the connecting plate 301 is driven downward by the linkage plate 304, so that the copper sheet in the connecting groove 302 fits tightly with the screw of the corresponding pole, and electricity is supplied through the wire 702. At the same time, the current detector connected to the detection component 3 detects the current.
