Description

Technical Field

[0001] The invention belongs to the technical field of protector testing, and in particular relates to a large current injection source device. Background Art

[0002] A current generator, also known as a current booster or high current test equipment, is a device that can output high-intensity current. It can generate currents ranging from tens of amperes to hundreds of thousands of amperes, and this type of equipment plays an important role in many fields, including power system maintenance, material research, and electronic equipment testing. In power system protector testing, a high current injection source is used to simulate fault currents under actual operating conditions to verify the performance and reliability of the protector.

[0003] High current injection sources for power system protector testing are specially designed devices that can generate high-intensity currents to meet specific testing needs. Such devices are essential to ensure the safe operation of power systems because they can simulate currents under extreme conditions to verify the performance of protectors in real-world applications.

[0004] Although current generators are widely used in many fields, existing technologies have some limitations. First, the current generator is usually divided into two parts: one part is used for current generation, and the other part is used for presenting the circuit. This design requires the two parts to be handled separately when carrying and transporting, which is inconvenient to use. Secondly, the current output circuit and the current port of the existing current generator are usually connected with bolts and nuts, which makes the installation and disassembly of the current output circuit more troublesome. In addition, once the connected circuit is tripped, the force at the connection between the current output circuit and the current port is easily concentrated, which may cause breakage and pose certain safety hazards.

[0066] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] An embodiment of the present invention provides a large current injection source device, comprising: an equipment main body, a control console is arranged on the upper layer of the equipment main body, and a storage box is arranged on the lower layer; the storage box is used to store the current output line; the control console is provided with a current port, a first transmission component, a second transmission component, an extrusion component and a fixing component; the current port is used to output current through the current output line; the extrusion component has an extrusion surface, and the extrusion component is used to extrude and fix the current output line on the table top of the control console through the extrusion surface; the fixing component has a fixing hole, and the fixing component is used to fix the extruded and fixed current output line through the fixing hole for secondary fixation, and then lead it out from one side of the control console to the outside of the equipment main body; the first transmission component and the second transmission component are transmission coupled and connected; the first transmission component is used to transmit the extrusion component so that the extrusion surface extrude and fix the current output line; the second transmission component is used to transmit the fixing component while the first transmission component is transmitting, so that the current output line passes through the fixing hole, thereby realizing secondary fixation.

[0068] In this embodiment, by providing a storage box, the user can conveniently organize and store the current output line, making the entire device more portable. In addition, through the cooperation of the first transmission assembly and the extrusion assembly, the extrusion surface of the extrusion assembly contacts the current output line and presses it against the table top of the console, thereby realizing the first fixation of the current output line. Then, while the extrusion assembly is in motion, the second transmission assembly is also started. The second transmission assembly drives the fixing assembly to move so that the current output line passes through the fixing hole. The design of the fixing hole enables the current output line to be fixed again after being squeezed and fixed, thereby increasing the stability of the connection. After completing the secondary fixation, the current output line is led out from one side of the console to the outside of the device body, so that the user can safely connect other devices and start using the current output line to transmit current.

[0069] This embodiment provides a large current injection source device, which achieves stable fixation and convenient storage of the current output line through the design of an integrated control console, a storage box, an extrusion component and a fixing component, thereby improving the portability and ease of use of the large current injection source device.

[0070] In one embodiment, the extrusion assembly includes: a pressing plate, two limiting plates and two extrusion plates; the pressing plate is arranged above the current port, and one side of the pressing plate is an extrusion surface; the two limiting plates are symmetrically arranged on both sides of the current port; a guide groove is arranged in the limiting plate; the two extrusion plates are respectively arranged on the sides of the two extrusion plates, and the extrusion plates are connected to the first transmission assembly; an extrusion groove is arranged in the extrusion plate; the two ends of the pressing plate are respectively slidably connected to the guide grooves and the extrusion grooves on both sides; the extrusion plate is used to make the end of the pressing plate move in the extrusion groove and the guide groove by rotating; the limiting plate is used to guide the extrusion surface of the pressing plate to move in the direction close to or away from the console table through the guide groove, thereby squeezing, fixing or releasing the current output line.

[0071] In this embodiment, an extrusion groove is provided in the extrusion plate, and its main function is to form a sliding connection with the end of the pressing plate. When the extrusion plate is driven by the first transmission assembly to rotate, the sliding connection in the extrusion groove guides the end of the pressing plate to move in the extrusion groove. The guide groove is provided in the limit plate, and its main function is to provide a track for the end of the pressing plate to slide. The guide groove and the extrusion groove work together to ensure that the pressing plate slides along the contour track of the guide groove. The guide groove guides the extrusion surface of the pressing plate to maintain an accurate position and direction in the process of approaching or moving away from the console table, ensuring that the pressing plate can smoothly compress or release the current output line.

[0072] In this embodiment, the pressing plate, the limiting plate and the extrusion plate are linked to each other, and the first transmission assembly is used to drive the extrusion plate to rotate, so that the pressing plate slides in the guide groove and the extrusion groove, thereby realizing the movement of the pressing surface of the pressing plate approaching or moving away from the console table, thereby completing the fixing or releasing of the current output line. This design ensures the stability and reliability of the current output line during use.

[0073] In one embodiment, a limiting groove is provided in the guide groove, and the pressing plate is slidably connected in the limiting groove via a limiting block.

[0074] In this embodiment, the limiting groove is used to provide more precise position control based on the guide groove to prevent the pressing plate from deflecting or shaking during movement.

[0075] In one embodiment, the pressure plate is provided with a mounting hole, the position and shape of the mounting hole are adapted to the position and shape of the current port, and the contour shape of the guide groove close to the current port is a vertical rectangular groove, which is used to guide the pressure plate to move toward or away from the current port.

[0076] In this embodiment, when the current output line needs to be fixed, the pressing plate moves along the vertical rectangular groove in the guide groove toward the current port under the drive of the transmission assembly. The pressing plate is connected to the current port through the mounting hole, and the pressing plate continues to descend until the extrusion surface of the pressing plate presses the current output line and fixes it on the console table. When the current output line needs to be released, the pressing plate moves upward along the vertical rectangular groove under the drive of the transmission assembly. After the pressing plate is lifted, the current output line is released.

[0077] In this embodiment, a mounting hole compatible with the current port is set on the pressure plate, and the guide groove is designed to be a vertical rectangular groove close to the current port, ensuring that the pressure plate can move accurately in the vertical direction to achieve the matching connection between the mounting hole and the current port, thereby effectively fixing and releasing the current output line and improving the reliability and stability of the device.

[0078] In one embodiment, the first transmission assembly includes: a transmission shaft; the transmission shaft is fixedly connected to the extrusion plate; the transmission shaft is transmission coupled to the second transmission assembly via a meshing connector, and the transmission shaft is used to convert the transmission motion of the meshing connector into the rotational motion of the extrusion plate.

[0079] In this embodiment, when the transmission shaft rotates, the extrusion plate will also rotate. The transmission shaft is transmission-coupled with the second transmission assembly via a meshing connection member. The meshing connection member can be a gear, a rack or other mechanical parts capable of achieving power transmission.

[0080] In one embodiment, the fixing assembly includes: an upper clamping plate and a lower clamping plate; the upper clamping plate and the lower clamping plate are both arranged on one side of the console where the current output line is led out, and semicircular grooves are arranged at corresponding positions of the upper clamping plate and the lower clamping plate; the position of the semicircular groove of the lower clamping plate corresponds to the position of the current port; the upper clamping plate is connected to the second transmission assembly; the upper clamping plate is used to overlap with the lower clamping plate by rotation, so that the semicircular grooves of the two clamping plates form a fixing hole.

[0081] In this embodiment, when the current output line needs to be fixed, the second transmission component is started to drive the upper clamping plate to rotate. After the upper clamping plate rotates to a certain angle, its semicircular groove is aligned with and overlaps with the semicircular groove of the lower clamping plate. When the upper clamping plate is completely overlapped on the lower clamping plate, the two semicircular grooves form a complete circular fixing hole, and the current output line is clamped between the upper and lower clamping plates, and secondary fixation is achieved through the fixing hole. When the current output line needs to be released, the second transmission component drives the upper clamping plate to rotate in the reverse direction, and the upper clamping plate leaves the lower clamping plate, the fixing hole between the two disappears, and the current output line is released.

[0082] This embodiment realizes secondary fixation of the current output line through the design of the upper clamping plate and the lower clamping plate, and their linkage with the second transmission assembly. When the upper clamping plate overlaps with the lower clamping plate by rotation, the combination of the semicircular grooves of the two forms a complete fixing hole, thereby ensuring that the current output line will not loosen during use, and improving the stability of the connection.

[0083] In one embodiment, the second transmission assembly includes: a round rod and a second gear; the round rod is fixedly connected to the upper clamp; one end of the round rod is fixedly connected to the second gear; the second gear is transmission coupled to the first transmission assembly via a meshing connection; the round rod is used to convert the transmission motion of the meshing connection into the rotational motion of the upper clamp.

[0084] In this embodiment, when the current output line needs to be fixed, the second gear is driven to rotate through the meshing connector, and the rotation of the second gear is transmitted to the upper clamping plate through the round rod. The round rod drives the upper clamping plate to rotate so that the upper clamping plate covers the lower clamping plate, and the semicircular groove of the upper clamping plate is aligned and overlapped with the semicircular groove of the lower clamping plate to form a complete fixing hole. The current output line is clamped between the upper and lower clamping plates, and secondary fixation is achieved through the fixing hole. When the current output line needs to be released, the second gear is driven to rotate in the opposite direction through the meshing connector, and the reverse rotation of the second gear is transmitted to the upper clamping plate through the round rod. The upper clamping plate rotates in the opposite direction and detaches from the lower clamping plate, and the fixing hole between the upper clamping plate and the lower clamping plate disappears, and the current output line is released.

[0085] In one embodiment, the meshing connection member includes: a first meshing connection portion, a second meshing connection portion, a connecting rod and an adjusting button; the first meshing connection portion and the second meshing connection portion are both arranged on the connecting rod, and are respectively used to mesh with the first transmission assembly and the second transmission assembly; the adjusting button is connected to the end of the connecting rod away from the console, and the adjusting button is used to drive the connecting rod to rotate by rotation, and the rotational movement of the connecting rod is the transmission movement of the meshing connection member.

[0086] In this embodiment, when the second transmission assembly needs to be driven, the operator rotates the adjustment knob. The rotation of the adjustment knob drives the connecting rod to rotate, and the rotation of the connecting rod causes the first meshing connection part and the second meshing connection part to rotate synchronously, and transmit power to the first transmission assembly and the second transmission assembly respectively, thereby driving the extrusion plate and the upper clamping plate to rotate respectively.

[0087] In one embodiment, it also includes: a storage and fixing component; a placement groove that is adapted to the shape of the side of the storage box is opened on the side of the device body; the storage and fixing component includes a baffle, a pad, a transmission rod and a reset spring component; the baffle is arranged at the edge between the placement groove and the storage box; the pad is arranged at the bottom of the device body; the transmission rod is slidably connected to the side of the device body, and the two ends of the transmission rod are respectively fixedly connected to the baffle and the pad; the reset spring assembly is fixedly connected to the baffle; the reset spring assembly is used to keep the baffle in position at the edge; the pad is used to push the baffle away from the edge through the transmission rod.

[0088] In this embodiment, the baffle is maintained at the edge position under the action of the reset spring assembly, and the storage box is fixed in the placement slot. The foot is located at the bottom of the device body and does not apply thrust. When the storage box needs to be released, the foot is affected by the gravity of the device body, provides a reverse thrust to the transmission rod, and pushes the baffle through the transmission rod to make the baffle lift off the edge position. After the baffle leaves the edge position, the storage box can be taken out. When storage is needed, push the storage box into the placement slot, and then lift the device body. The gravity on the foot is released, the transmission rod no longer provides a reverse thrust, and the baffle is affected by the reset spring assembly. After returning to the initial position, the storage box is fixed again.

[0089] In one embodiment, an anti-skid layer is disposed on both the extrusion surface and the fixing hole. The anti-skid layer can further improve the fixing reliability of the current output circuit.

[0091] Among them, the upper clamping plate 29 and the lower clamping plate 25 are both designed in an arch bridge structure. The upper clamping plate 29 and the lower clamping plate 25 are fixedly connected to a symmetrically arranged rubber layer 31 on one side opposite to the lower clamping plate 25. The rubber layer 31 is provided with an anti-skid groove 32 on one side, so that the upper clamping plate 29 and the lower clamping plate 25 can clamp and fix the current output line through the rubber layer 31.

The extrusion groove 22 provided in the extrusion plate 21 is designed in a rectangular structure. The arc trajectory of the extrusion plate 21 moving with the transmission shaft 20 as the axis is larger than the L-shaped trajectory of the extrusion shaft 17 moving along the guide groove 14, so that the extrusion plate 21 can extrusion drive the extrusion shaft 17 through the extrusion groove 22, so as to avoid jamming due to insufficient transmission distance.
