Description

Technical Field

[0001] This invention relates to the field of intelligent reactor manufacturing technology, specifically to a voltage monitoring device for smart grids. Background Technology

[0002] In the development of the smart grid industry, intelligent reactors are core equipment, and their manufacturing precision and stability directly affect the power supply quality of the grid. As the industry's demand for "miniaturization and high power density" of reactors upgrades, the core welding process faces significant electrostatic problems, and traditional control methods have obvious limitations.

[0003] For example, the patent document with publication number CN214350438U describes an automated equipment for welding EI-type reactors. When this equipment is used to weld reactors, static electricity can easily accumulate in the coils, iron cores and other components used to manufacture reactors during the cutting and handling processes. Static electricity can attract dust and welding slag, leading to poor welding and slag inclusions at the welding points, reducing conductivity and insulation performance, and even causing electrostatic discharge, interfering with the welding current and creating safety hazards.

[0004] To address this, we designed a smart grid voltage monitoring device that can monitor and eliminate static electricity in real time and in a targeted manner, and integrate welding processes. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The electrostatic voltage monitoring component, by fixing the metal contact piece to the surface of the positioning clamp, can directly contact the surface of the reactor to be welded. Combined with the positive and negative detection lines of the electrostatic voltage detector, it can capture the changes in surface electrostatic voltage during reactor welding in real time. Compared to the problem of traditional external detection being easily affected by environmental interference, the detection end of this device is in direct contact with the reactor, avoiding the influence of airflow, dust, and other factors on the detection signal, ensuring improved accuracy of electrostatic voltage data, and providing accurate judgment for subsequent electrostatic elimination. In the high-temperature, high-frequency working environment of reactor welding, the electrostatic voltage may fluctuate with the welding position and current changes. By continuously monitoring the electrostatic voltage value, the device can provide real-time warnings of the risk of exceeding the electrostatic limit. When the voltage exceeds the safety threshold, the operator can promptly suspend the welding operation to avoid electrostatic discharge breaking down the reactor insulation layer and interfering with the stability of the welding current, thereby eliminating quality problems such as incomplete welding and missed welding, and ensuring the welding reliability of the reactor coil and shell.

[0019] (2) The neutralization component, based on the structural design of the annular limiting frame, fixes two electron jet tubes to the side of the reactor to be welded area. The internal discharge cone, driven by the discharge controller and the battery, can directionally spray electrons onto the reactor surface. This targeted electron neutralization method can accurately offset the excess charge accumulated on the reactor surface due to material processing and handling before welding, ensuring that the electrostatic elimination rate in the welding area reaches a certain level, thus cutting off the safety risks such as sparks and equipment short circuits caused by electrostatic discharge from the source. After the reactor is fixed by the positioning clamp, the neutralization component can start the electron jet operation simultaneously without adding extra steps or stopping the machine. Compared with traditional reactor welding equipment, this device realizes parallel processing of monitoring-neutralization-welding, reducing the time cost of welding a single reactor.

[0020] (3) The gas circulation component absorbs the airflow in the welding area through the strip-shaped suction hood. In conjunction with the inclined impurity removal filter in the gas treatment box, it can simultaneously filter metal dust and welding slag particles adsorbed by electrostatics in the airflow. On the one hand, it avoids impurities adhering to the welding interface of the reactor and affecting its conductivity; on the other hand, it reduces the probability of impurities being re-adsorbed onto the reactor surface due to electrostatics, ensuring that the coil insulation layer is not easily broken down by impurities when the reactor is running in the smart grid after leaving the factory, thus extending the service life of the equipment. The flow fan in the guide tube blows air upward under the drive of the motor, forming a downward-blowing and upward-suctioning airflow circulation with the suction of the strip-shaped suction hood. This can break the unstable distribution of the local electrostatic field in the welding area, so that the electrons released by the electron jet tube can more evenly neutralize the charge on the reactor surface, further improving the uniformity and thoroughness of static elimination.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-8 The present invention provides a technical solution: a voltage monitoring device for smart grids, wherein the surface of the operating console 1 is provided with a reactor limiting component 2, a static voltage monitoring component 3, a neutralization component 4, a gas circulation component 5 and a welding component 6.

[0037] The reactor limiting assembly 2 is the core structure that ensures the stability of the reactor welding position. Two limiting plates 201 are fixedly installed on the surface of the operating table 1. The two limiting plates 201 are symmetrically distributed, and their center of symmetry coincides with the center of the annular limiting frame 401, i.e., they are located on the left and right sides of the annular limiting frame 401, respectively. On the side of the two limiting plates 201 that are far apart from each other, a limiting shell 202 is fixedly connected. The inner wall of the limiting shell 202 is fitted with a bidirectional screw 203 by a rotatable connection. The surface of the bidirectional screw 203 is machined with a matching thread, which forms a threaded connection with the threaded hole in the inner wall of the adjusting block 204. The end of the adjusting block 204 extends out of the limiting shell 202 and is fixedly connected with a positioning clamp 205. The positioning clamp 205 can clamp or loosen the reactor as the adjusting block 204 moves.

[0038] This structure ensures that the reactor does not shift during welding through mechanical clamping, preventing misalignment of the welding points due to positional wobbling and significantly improving welding accuracy. The top of the bidirectional screw 203 extends upward to the outside of the limiting shell 202, and an adjustment knob is fixedly mounted on the top for easy manual adjustment by the operator. At the same time, the surface of the limiting plate 201 has a rectangular limiting hole that matches the shape of the adjusting block 204. The side of the adjusting block 204 is slidably connected to the inner wall of the rectangular limiting hole, which restricts the adjustment block 204 from rotating with the bidirectional screw 203, ensuring that the adjusting block 204 moves stably only in the horizontal direction, further enhancing the clamping stability of the positioning clamp 205.

[0039] The electrostatic voltage monitoring component 3 is used to capture the electrostatic state of the reactor surface in real time. Its assembly is deeply linked with the operating platform 1 and the reactor limiting component 2: A mounting plate is fixedly installed on the surface of the operating platform 1, and an electrostatic voltage detector 301 is fixedly installed on the side of the mounting plate. As the core device for electrostatic monitoring, it can display and record voltage data in real time. The detection ends of the electrostatic voltage detector 301 are respectively connected to the positive detection line 302 and the negative detection line 303. The ends of the two detection lines away from the electrostatic voltage detector 301 are fixedly connected to metal contact pieces 304, and the two metal contact pieces 304 are respectively fixed to the inner surface of the two positioning clamps 205.

[0040] When the positioning clamp 205 clamps the reactor, the metal contact piece 304 can directly adhere to the surface of the reactor, avoiding interference from airflow and dust on the signal in traditional external testing, ensuring accurate electrostatic voltage data, providing a reliable basis for subsequent neutralization operations, and preventing untimely or excessive electrostatic elimination due to testing errors.

[0041] Neutralization component 4 is the core structure for eliminating static electricity on the reactor surface. Its assembly is arranged around the surface of the operating platform 1. An annular limiting frame 401 and a battery 402 are fixedly mounted on the surface of the operating platform 1. The annular limiting frame 401 assists in limiting the reactor and provides a directional reference for electron injection. The battery 402 provides stable power for the neutralization operation. Two electron injection tubes 403 are fixedly embedded in the left side wall of the annular limiting frame 401, with the injection direction facing the reactor inside the annular limiting frame 401, ensuring that electrons can be directed to the static accumulation area. A discharge cone 404 is fixedly installed inside the electron injection tube 403, serving as a key component for electron release. A discharge controller 405 is fixedly mounted on the upper surface of the battery 402, and the discharge controller 405 is electrically connected to the battery 402 and the discharge cone 404 via conductive cables.

[0042] The discharge controller 405 can adjust the discharge intensity of the discharge cone 404 based on the feedback data from the electrostatic voltage monitoring component 3, so that the electron jet tube 403 can directionally spray electrons to precisely neutralize the excess charge on the surface of the reactor, cut off the risk of sparks and short circuits caused by electrostatic discharge from the source, and ensure the safety of welding operations.

[0043] The gas circulation component 5 is used to purify the airflow in the welding area and assist in static electricity elimination. A guide cylinder 501 is fixedly connected to the lower surface of the operating table 1. The position of the guide cylinder 501 corresponds directly to the annular limiting frame 401 (i.e., it is located directly below the annular limiting frame 401), ensuring that the airflow acts vertically on the welding area. The top of the guide cylinder 501 extends upward to the top of the operating table 1, and a conical mesh cover 502 is fixedly installed on the top. The conical mesh cover 502 can prevent welding slag and impurities from falling into the guide cylinder 501, avoiding blockage and affecting airflow circulation. A shaft hole is opened in the inner bottom wall of the guide cylinder 501. A rotating shaft 503 is rotatably connected to the inner wall of the shaft hole through a bearing. A flow-guiding fan 504 is fixedly installed on the top of the rotating shaft 503. The air outlet of the flow-guiding fan 504 faces upward to the operating table 1, which can deliver airflow upward to form a circulation base.

[0044] The bottom end of the rotating shaft 503 extends to the outside of the guide tube 501, and a first transmission synchronous pulley 505 and a second transmission synchronous pulley 506 (distributed along the axial direction) are fixedly connected to its surface. Two support plates 7 are symmetrically arranged on the lower surface of the operating table 1. A drive motor 507 is fixedly mounted on the surface of the right support plate 7. The rotating shaft of the drive motor 507 is fixedly connected to a drive synchronous pulley 508. The drive synchronous pulley 508 and the first transmission synchronous pulley 505 are connected by a first transmission belt 509. The drive motor 507 can drive the rotating shaft 503 and the guide fan 504 to rotate through the transmission structure, eliminating the need for multiple power sources and reducing energy consumption.

[0045] A gas treatment box 510 is fixedly mounted on the lower surface of the operating table 1. A diversion tube 511 is fixedly embedded in the lower surface of the diversion tube 511. A diversion conduit 512 is rotatably connected to the bottom wall of the diversion tube 511. Diversion fan blades 513 are evenly distributed at the bottom of the diversion conduit 512 (the air inlet faces the gas treatment box 510), which can draw in airflow from the box. A third transmission synchronous pulley 514 is fixedly connected to the bottom end of the diversion conduit 512. It is driven by the second transmission synchronous pulley 506 through the second transmission belt 515. When the rotating shaft 503 rotates, it can drive the diversion fan blades 513 to rotate, realizing directional airflow delivery.

[0046] An air inlet pipe 516 is fixedly embedded at the bottom of the guide tube 501. The bottom end of the air inlet pipe 516 is connected to the air guide pipe 517, and the other end of the air guide pipe 517 is rotatably connected to the bottom end of the drainage conduit 512, so as to realize the airflow communication between the drainage tube 511 and the guide tube 501. An inclined impurity removal filter screen 518 is fixed on the inner wall of the gas treatment box 510. The inclined design increases the filtration area and can effectively filter metal dust and welding slag, avoiding impurities from affecting the conductivity and service life of the reactor. An air intake pipe 519 is fixedly embedded on the back of the gas treatment box 510 for drawing in external airflow.

[0047] A support frame 520 is fixed to the surface of the operating table 1. A strip-shaped suction hood 521 is fixed to the top of the support frame 520, corresponding to the position of the annular limiting frame 401 (covering the welding area). The other end of the suction pipe 519 extends into the interior of the strip-shaped suction hood 521. The strip-shaped suction hood 521 can directionally absorb the airflow in the welding area, ensuring that impurities enter the circulation system in a timely manner. A guide shell 522 is fixedly connected to the top of the strip-shaped suction hood 521, which can guide the airflow direction and avoid turbulence affecting welding and electrostatic field stability.

[0048] Welding assembly 6 enables automated welding of reactors and is adjustable in multiple directions. A fixed base 601 is fixed to the surface of the operating table 1. A support arm 602 is rotatably connected to the upper surface of the fixed base 601. An extension arm 603 is rotatably mounted at the top of the support arm 602, and a horizontal adjustment housing 604 is fixedly connected to the end of the extension arm 603. A horizontal screw 605 is rotatably connected to the inner wall of the horizontal adjustment housing 604, and a movable frame 607 is threaded onto its surface. The bottom end of the movable frame 607 extends to the outside and is rotatably connected to a movable block 608. A welding torch head 606 is fixedly mounted at the front end of the movable block 608. The movable block 608 can finely adjust the angle of the welding torch head 606 to ensure precise welding.

[0049] To achieve automated adjustment, a first adjustment motor 611 is fixed to the back of the fixed base 601. Its rotating shaft extends internally and fixes a drive bevel gear 612. A driven bevel gear 613 (meshing with the drive bevel gear 612) is rotatably connected to the inner bottom wall of the fixed base 601. The bottom end of the support arm 602 is fixed to the top of the driven bevel gear 613. The first adjustment motor 611 can drive the support arm 602 to rotate, adjusting the welding angle. A second adjustment motor 609 is fixed to the top side of the support arm 602. Its rotating shaft is fixed to the surface of the extension arm 603, driving the extension arm 603 to rotate, expanding the welding range. A third adjustment motor 610 is fixed to the end of the horizontal adjustment housing 604. Its rotating shaft is fixed to one end of the horizontal screw 605, driving the horizontal screw 605 to rotate, causing the moving frame 607 to drive the welding torch head 606 to adjust horizontally, improving welding flexibility.

[0050] Working Principle: The reactor is placed in the annular limiting frame 401, and the bidirectional screw 203 is rotated to adjust the positioning clamp 205 to clamp the reactor. The metal contact piece 304 is attached to the surface of the reactor. The electrostatic voltage detector 301 is activated to monitor the electrostatic voltage in real time. The drive motor 507 is started, which drives the diversion fan 504 and diversion fan blades 513 to rotate through the transmission structure. The diversion fan 504 blows air upward, and the diversion fan blades 513 draw in the airflow from the gas treatment box 510. The airflow enters the guide tube 501 through the air guide pipe 517 and the air inlet pipe 516. At the same time, the strip-shaped suction hood 521 draws in the airflow from the welding area. The airflow enters the gas treatment box 510 through the suction pipe 519, is filtered by the impurity removal filter 518, and then circulated, forming a purified airflow that is delivered from below and drawn in from above, stabilizing the electrostatic field. If the electrostatic voltage detector 301 detects that the voltage exceeds the standard, the discharge controller 405 controls the discharge cone 404 to release electrons. The electron jet tube 403 sprays electrons in a directional manner to neutralize the excess charge until the voltage drops to a safe range. According to the welding requirements, the first adjusting motor 611 and the third adjusting motor 610 are started respectively, thereby adjusting the position and angle of the support arm 602, the extension arm 603 and the welding gun head 606. After aligning with the welding point, the welding gun head 606 is started to weld. During welding, the electrostatic monitoring and neutralization component 4 is on standby, and the gas circulation component 5 continuously purifies the airflow.
