Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of protective device testing, and particularly relates to a large-current injection source device. BACKGROUND

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

[0003] A large-current injection source for power system protector testing is a specially designed device that can generate high-intensity current to meet specific testing needs. This device is crucial for ensuring the safe operation of power systems, as it can simulate current under extreme conditions to verify the performance of the protector in actual applications.

[0004] Although current generators have a wide range of applications in multiple fields, existing technologies have some limitations. First, current generators are usually divided into two parts: one for current generation and the other for presenting the line. This design results in the need to handle the two parts separately when carrying and transporting, making it less convenient to use. Second, the current output line and current port of existing current generators are usually connected by bolts and nuts, which makes the installation and removal of the current output line more cumbersome. In addition, once the connected line is bumped, the connection between the current output line and the current port may be concentrated under stress, which may cause breakage and pose a certain safety hazard.

[0067] ​The embodiment of the application provides a large-current injection source device, which comprises a device main body, a control console arranged on the upper layer of the device main body, and a storage box arranged on the lower layer of the device main body; the storage box is used for storing a current output line; the control console is provided with a current port, a first transmission assembly, a second transmission assembly, a pressing assembly and a fixing assembly; the current port is used for outputting current through the current output line; the pressing assembly has a pressing surface, and the pressing assembly is used for pressing and fixing the current output line on the tabletop of the control console through the pressing surface; the fixing assembly has a fixing hole, and the fixing assembly is used for secondarily fixing the current output line after the pressing and fixing, and leading the current output line out of the device main body from one side of the control console; the first transmission assembly and the second transmission assembly are transmissionally and coupledly connected; the first transmission assembly is used for transmitting to the pressing assembly, so that the pressing surface presses and fixes the current output line; and the second transmission assembly is used for transmitting to the fixing assembly at the same time as the first transmission assembly transmits, so that the current output line passes through the fixing hole, thereby realizing secondary fixing.

[0068] In the embodiment, the storage box is arranged, so that a user can conveniently arrange and store the current output line, and the whole device is more portable. In addition, the first transmission assembly and the pressing assembly are matched, so that the pressing surface of the pressing assembly contacts the current output line and presses the current output line on the tabletop of the control console, thereby realizing first fixing of the current output line. Then, the second transmission assembly is started at the same time as the pressing assembly acts. 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 pressed and fixed, and the stability of connection is increased. After the secondary fixing is completed, the current output line is led out of the device main body from one side of the control console, so that the user can safely connect other devices and start to use the current output line to transmit current.

[0069] The embodiment provides a large-current injection source device, which realizes stable fixing and convenient storage of the current output line through the design of the integrated control console, the storage box, the pressing assembly and the fixing assembly, and improves the portability and use convenience of the large-current injection source device.

[0070] In one embodiment, the pressing assembly comprises a pressing plate, two limiting plates and two pressing plates; the pressing plate is arranged above the current port, and one side of the pressing plate is a pressing surface; the two limiting plates are symmetrically arranged on the two sides of the current port; the limiting plate is provided with a guide groove; the two pressing plates are respectively arranged on the side surfaces of the two pressing plates, and the pressing plates are connected with the first transmission assembly; the pressing plate is provided with a pressing groove; the two ends of the pressing plate are respectively slidably connected in the guide grooves and the pressing grooves on the two sides; the pressing plate is used for moving the end of the pressing plate in the pressing groove and the guide groove in a rotating manner; and the limiting plate is used for guiding the pressing surface of the pressing plate to move in the direction of approaching or moving away from the tabletop of the control console through the guide groove, so as to press and fix or release 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. A 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 when approaching or moving away from the console table, ensuring that the pressing plate can smoothly compress or release the current output line.

[0072] This embodiment utilizes a linkage mechanism among the pressure plate, the limit plate, and the extrusion plate. The first transmission assembly drives the extrusion plate to rotate, causing it to slide within the guide and extrusion grooves. This allows the extrusion surface of the pressure plate to move closer to or further from the console surface, thereby securing or releasing the current output cable. This design ensures the stability and reliability of the current output cable during use.

[0073] In one embodiment, a limiting groove is provided in the guide groove, and the pressing plate is slidably connected to 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, so as to prevent the pressure 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, to secure the current output cable, the pressure plate, driven by the transmission assembly, moves along the vertical rectangular slot in the guide toward the current port. The pressure plate engages the current port through the mounting hole. The pressure plate continues to descend until its pressing surface compresses the current output cable, securing it to the console surface. To release the current output cable, the pressure plate, driven by the transmission assembly, moves upward along the vertical rectangular slot. When the pressure plate is lifted, the current output cable is released.

[0077] In this embodiment, a mounting hole that is compatible with the current port is provided on the pressure plate, and the guide groove is designed as 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 comprises a transmission shaft, the transmission shaft is fixedly connected with the extrusion plate, and the transmission shaft is transmissionally and couplingly connected with the second transmission assembly through the meshing connecting piece, and the transmission shaft is used for converting the transmission movement of the meshing connecting piece into the rotating movement of the extrusion plate.

[0079] In this embodiment, when the transmission shaft rotates, the extrusion plate also rotates. The transmission shaft is transmissionally and couplingly connected with the second transmission assembly through the meshing connecting piece. The meshing connecting piece can be a gear, a rack or other mechanical parts capable of realizing power transmission.

[0080] In one embodiment, the fixing assembly comprises an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are arranged on one side of the control console outgoing current output line, and the corresponding positions of the upper clamping plate and the lower clamping plate are provided with semicircular grooves, 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 with the second transmission assembly, and the upper clamping plate is used for being overlapped on the lower clamping plate in a rotating manner 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 assembly is started to drive the upper clamping plate to rotate, the semicircular groove of the upper clamping plate is aligned and overlapped with the semicircular groove of the lower clamping plate after the upper clamping plate rotates to a certain angle, when the upper clamping plate is completely overlapped on the lower clamping plate, the two semicircular grooves form a complete circular fixing hole, the current output line is clamped between the upper and lower clamping plates, and secondary fixing is realized through the fixing hole. When the current output line needs to be released, the second transmission assembly reversely drives the upper clamping plate to rotate, the upper clamping plate is separated from the lower clamping plate, the fixing hole between the two is disappeared, and the current output line is released.

[0082] In this embodiment, the secondary fixing of the current output line is realized through the design of the upper clamping plate and the lower clamping plate and the linkage of the two with the second transmission assembly. When the upper clamping plate is overlapped with the lower clamping plate in a rotating manner, the combination of the semicircular grooves of the two forms a complete fixing hole, so that the current output line is ensured not to be loose during use, and the stability of the connection is improved.

[0083] In one embodiment, the second transmission assembly comprises a round rod and a second gear, the round rod is fixedly connected with the upper clamping plate, one end of the round rod is fixedly connected with the second gear, the second gear is transmissionally and couplingly connected with the first transmission assembly through the meshing connecting piece, and the round rod is used for converting the transmission movement of the meshing connecting piece into the rotating movement of the upper clamping plate.

[0084] In the embodiment, when the current output line needs to be fixed, the second gear is driven to rotate by the engagement connecting piece, the rotation of the second gear is transmitted to the upper clamping plate through the round rod, the upper clamping plate is driven to rotate by the round rod, the upper clamping plate covers the lower clamping plate, the semicircular groove of the upper clamping plate is aligned with and overlaps the semicircular groove of the lower clamping plate, a complete fixing hole is formed, the current output line is clamped between the upper and lower clamping plates, and the current output line is fixed again through the fixing hole.

The first and second engagement connecting parts are arranged on the connecting rod and are used for engaging with the first and second transmission assemblies respectively. The adjusting knob is connected to the end of the connecting rod away from the console and is used for driving the connecting rod to rotate in a rotating manner. The rotating movement of the connecting rod is the transmission movement of the engagement connecting piece.

[0086] In the embodiment, when the second transmission assembly needs to be driven, the operator rotates the adjusting knob. The rotation of the adjusting knob drives the connecting rod to rotate, and the rotation of the connecting rod synchronously drives the first and second engagement connecting parts to rotate and respectively transmit power to the first and second transmission assemblies, so as to respectively drive the pressing plate and the upper clamping plate to rotate.

[0087] In one embodiment, the device further comprises a receiving and fixing assembly. A placing groove is formed in the side of the device main body and is matched with the shape of the side of the receiving box.

The reset spring assembly is fixedly connected to the baffle. The reset spring assembly is used for keeping the baffle at the edge position. The pad foot is used for pushing the baffle away from the edge position through the transmission rod.

[0088] In the embodiment, the baffle is kept at the edge position under the action of the reset spring assembly, and at this time, the receiving box is fixed in the placing groove. The pad foot is located at the bottom of the device main body and does not exert a pushing force. When the receiving box needs to be released, the pad foot is subjected to the gravity of the device main body, provides a reverse pushing force to the transmission rod, and pushes the baffle away from the edge position through the transmission rod. After the baffle leaves the edge position, the receiving box can be taken out. When the receiving box needs to be received, the receiving box is pushed into the placing groove, and then the device main body is lifted. The gravity of the pad foot is released, the transmission rod no longer provides the reverse pushing force, and the baffle is kept at the initial position under the action of the reset spring assembly.
