Description

Technical Field

[0001] This utility model relates to the field of microcomputer excitation device technology, and in particular to a microcomputer excitation device with current regulation function. Background Technology

[0002] A microcomputer excitation device is a device that uses microcomputer control technology to control the excitation of generators in a power system. It calculates and adjusts the excitation current by measuring parameters such as current and voltage of the power system in real time, so as to achieve stable control of generator power output, current, voltage and frequency.

[0003] When using a microcomputer excitation device, the power system lines need to be connected to the terminals of the terminal block before the microcomputer excitation device can adjust the current and output power of the power system. However, the lines are mainly fixed to the terminals with bolts. If the lines are pulled by external forces, they may detach from the terminals, which will affect the normal operation of the microcomputer excitation device. Utility Model Content

[0004] This utility model addresses the problem that the circuit is mainly fixed to the terminal with bolts, and if the circuit is pulled by external force, it may detach from the terminal, thus affecting the normal operation of the microcomputer excitation device. The proposed microcomputer excitation device has a current regulation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a microcomputer excitation device with current regulation function, including an excitation controller body. Heat dissipation holes are evenly opened on both sides of the outer surface of the excitation controller body. A terminal block is fixedly installed on one side of the excitation controller body by screws. A plurality of terminals are evenly arranged on one side of the terminal block. Fixing devices are provided on the sides of two terminal blocks that are far apart. The fixing devices use pressure plates and bottoms to squeeze and fix the lines connected to the terminals.

[0006] The effect achieved by the above components is as follows: by setting pressure plates and base plates to squeeze and fix the circuit, when the circuit is subjected to external force, the connection between the circuit and the pressure plates and base plates is stretched first, and then the connection between the circuit and the terminal is stretched. This can reduce the pressure on the circuit when it is stretched, which helps to prevent the circuit from detaching from the terminal under the action of external force and can protect the connection between the circuit and the terminal.

[0007] Preferably, the fixing device includes a base plate, which is disposed on one side of the terminal block and fixedly installed on one side of the excitation controller body. One side of the base plate is flush with one side of the terminal block. A pressure plate is provided on one side of the base plate. A rectangular plate is symmetrically fixedly installed on one side of the outer surface of the pressure plate. A rectangular cylinder is slidably installed on the outer surface of the rectangular plate, and a bolt is threaded into the outer surface of the rectangular cylinder.

[0008] The effect achieved by the above components is as follows: the wire connected to the terminal passes through the base plate and the pressure plate, the pressure plate is pushed so that it is close to the base plate, the pressure plate will drive the rectangular plate to slide on the inner wall of the rectangular tube until the pressure plate and the base plate completely clamp the wire, and then the bolt is rotated so that one end of the bolt abuts against one side of the rectangular plate, which can fix the pressure plate. In this way, the pressure plate and the base plate can provide auxiliary fixation for the wire, which helps to prevent the wire from coming off the terminal under the action of external force.

[0009] Preferably, mounting blocks are provided at both ends of the pressure plate, and a disassembly assembly is provided between the mounting block and the pressure plate. The same spring is fixedly installed on one side of the mounting block and one side of the excitation controller body.

[0010] The effect achieved by the above components is as follows: by setting a spring, when the pressure plate is pushed towards the base plate, the mounting block will squeeze the spring, causing the spring to deform. When the bolt rectangular plate abuts, it can fix the deformed spring. At the same time, rotating the bolt will move the bolt away from the rectangular plate, and the spring will reset and automatically move the pressure plate away from the base plate, thus facilitating the maintenance of the circuit and other operations.

[0011] Preferably, the spring has a round rod inside, one end of which is fixedly installed on one side of the excitation controller body, and the other end of which is fixedly installed with a stop block.

[0012] The effect achieved by the above components is as follows: by setting the round rod, the round rod can limit and guide the spring, and at the same time, the stop block can block one end of the round rod, which helps to prevent the round rod from detaching from the inner wall of the mounting block.

[0013] Preferably, a rubber plate is fixedly installed on the side of the pressure plate near the base plate. The rubber plate has a number of protrusions evenly arranged on its surface, and the top of the base plate has a number of grooves evenly arranged on its surface. The size and shape of the protrusions and grooves are matched, and the grooves correspond one-to-one with the wiring terminals.

[0014] The effect achieved by the above components is as follows: by opening a groove on the top of the base plate, it is easy to place the wire in the groove. At the same time, when the rubber plate abuts against the base plate, the protrusion also enters the inner wall of the groove, thereby increasing the friction between the pressure plate and the base plate and the wire, making the wire more securely fixed.

[0015] Preferably, the disassembly and assembly assembly includes two locking blocks, which are disposed between the mounting block and the pressure plate. A circular hole block is symmetrically fixedly installed on the top of the locking block. A threaded pin is inserted into the inner wall of the circular hole block. One end of the two threaded pins is respectively installed on one side of the mounting block and the pressure plate. A nut is threadedly connected to the outer surface of the threaded pin.

[0016] The effect achieved by the above components is as follows: when the locking block is inserted between the mounting block and the pressure plate, and the threaded pin is inserted into the inner wall of the round hole block, the nut is rotated so that the nut presses against the round hole block until one side of each of the two round hole blocks abuts against one side of the round hole block and the pressure plate respectively, the pressure plate and the two mounting blocks can be fixed, and the pressure plate can be disassembled, which facilitates the individual disassembly and maintenance of the pressure plate. At the same time, one side of the mounting block can be disassembled individually, which facilitates the placement or removal of wires between the pressure plate and the base plate through the space between the mounting block and the pressure plate.

[0017] Preferably, a soft rubber pad is installed on one side of the nut, and the outer surface of the threaded pin is slidably inserted into the inner wall of the rubber pad.

[0018] The effect achieved by the above components is that by setting up soft rubber pads, the friction between the nut and the round hole block can be increased, which helps to prevent the nut from loosening.

[0019] Preferably, a U-shaped block is fixedly installed on one side of both the mounting block and the pressure plate, and the round hole block is inserted into the inner wall of the U-shaped block.

[0020] The effect achieved by the above components is that by setting the U-shaped block, it is easy to quickly position the round hole block, and at the same time, it can make the fixation between the two round hole blocks, the pressure plate and the mounting block more stable.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the circuit is pressed and fixed by setting a pressure plate and a base plate. When the circuit is subjected to external force, the connection between the circuit and the pressure plate and the base plate is subjected to tension first, and then the connection between the circuit and the terminal is subjected to tension. This reduces the fixing pressure of the screw on the circuit, helps prevent the circuit from detaching from the terminal under the action of external force, and protects the connection between the circuit and the terminal, which facilitates the normal operation of the microcomputer excitation device.

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses a microcomputer excitation device with current regulation function, including an excitation controller body 1. Heat dissipation holes 2 are evenly distributed on both sides of the outer surface of the excitation controller body 1. A terminal block 3 is fixedly installed on one side of the excitation controller body 1 by screws. Several terminals 4 are evenly distributed on one side of the terminal block 3. Fixing devices 5 are provided on the sides of two terminal blocks 3 that are far apart. The fixing devices 5 use pressure plates 52 and a bottom plate 51 to press and fix the lines connected to the terminals 4. By pressing and fixing the lines with pressure plates 52 and a bottom plate 51, when the lines are subjected to external force, the connection between the lines and pressure plates 52 and bottom plates 51 is pulled first, and only then is the connection between the lines and terminals 4 subjected to tension. This reduces the pressure on the lines when pulled, which helps prevent the lines from detaching from the terminals 4 under external force and protects the connection between the lines and terminals 4.

[0029] Reference Figure 3 and Figure 4As shown, the fixing device 5 includes a base plate 51, which is disposed on one side of the terminal block 3. The base plate 51 is fixedly installed on one side of the excitation controller body 1, and one side of the base plate 51 is flush with one side of the terminal block 3. A pressure plate 52 is provided on one side of the base plate 51. A rectangular plate 54 is symmetrically fixedly installed on one side of the outer surface of the pressure plate 52. A rectangular cylinder 55 is slidably installed on the outer surface of the rectangular plate 54. A bolt 56 is threaded into the outer surface of the rectangular cylinder 55. The line connected to the terminal block 4 passes through the base plate 51 and the pressure plate 52. Pushing the pressure plate 52 brings it closer to the base plate 51. The pressure plate 52 causes the rectangular plate 54 to slide on the inner wall of the rectangular cylinder 55 until the pressure plate 52 and the base plate 51 completely clamp the line. Then, the bolt 56 is rotated so that one end of the bolt 56 abuts against one side of the rectangular plate 54, thus clamping the pressure plate. 52 is fixed, and the pressure plate 52 and the base plate 51 can assist in fixing the line, which helps to prevent the line from detaching from the terminal 4 under the action of external force. Both ends of the pressure plate 52 are provided with mounting blocks 53, and a disassembly and assembly component 6 is provided between the mounting blocks 53 and the pressure plate 52. One side of the mounting block 53 and one side of the excitation controller body 1 are fixedly installed with the same spring 57. By setting the spring 57, when the pressure plate 52 is pushed towards the base plate 51, it will drive the mounting block 53 to squeeze the spring 57, causing the spring 57 to deform. When the bolt 56 and the rectangular plate 54 abut, the deformed spring 57 can be fixed. At the same time, rotating the bolt 56 will move the bolt 56 away from the rectangular plate 54, and the spring 57 will reset and automatically drive the pressure plate 52 away from the base plate 51, which facilitates the maintenance of the line and other operations.

[0030] Reference Figure 3 and Figure 4 As shown, a round rod 58 is provided inside the spring 57. One end of the round rod 58 is fixedly installed on one side of the excitation controller body 1, and a stop block 59 is fixedly installed on the other end of the round rod 58. By setting the round rod 58, the round rod 58 can limit and guide the spring 57. At the same time, the stop block 59 can block one end of the round rod 58, which helps to prevent the round rod 58 from detaching from the inner wall of the mounting block 53. A rubber plate 510 is fixedly installed on the side of the pressure plate 52 near the bottom plate 51. Several protrusions are evenly provided on the rubber plate 510, and several grooves are evenly provided on the top of the bottom plate 51. The size and shape of the protrusions and grooves are matched, and the grooves correspond one-to-one with the terminal 4. By opening grooves on the top of the bottom plate 51, it is easy to place the wire in the groove. At the same time, when the rubber plate 510 abuts against the bottom plate 51, the protrusions also just enter the inner wall of the groove, which can increase the friction between the pressure plate 52 and the bottom plate 51 and the wire, making the fixation of the wire more stable.

[0031] Reference Figure 3 and Figure 4As shown, the disassembly and assembly component 6 includes two locking blocks 61, which are positioned between the mounting block 53 and the pressure plate 52. A circular hole block 62 is symmetrically fixed to the top of the locking block 61. Threaded pins 63 are inserted into the inner wall of the circular hole block 62. One end of each threaded pin 63 is respectively installed on one side of the mounting block 53 and the pressure plate 52. Nuts 64 are threaded onto the outer surface of the threaded pins 63. The locking blocks 61 are inserted between the mounting block 53 and the pressure plate 52, causing the threaded pins 63 to insert into the inner wall of the circular hole block 62. The nuts 64 are then rotated. 4. This causes the nut 64 to press against the round hole block 62 until one side of each of the two round hole blocks 62 abuts against one side of the round hole block 62 and the pressure plate 52, respectively. This fixes the pressure plate 52 and the two mounting blocks 53, and also makes the pressure plate 52 removable. This facilitates the individual disassembly and maintenance of the pressure plate 52. At the same time, one side of the mounting block 53 can be disassembled individually, making it easier to place or remove the wiring between the pressure plate 52 and the base plate 51 through the space between the mounting block 53 and the pressure plate 52.

[0032] Reference Figure 3 and Figure 4 As shown, a soft rubber pad 65 is installed on one side of the nut 64, and the outer surface of the threaded pin 63 is slidably inserted into the inner wall of the rubber pad. By setting the soft rubber pad 65, the friction between the nut 64 and the round hole block 62 can be increased, which helps to prevent the nut 64 from loosening. A U-shaped block 66 is fixedly installed on one side of the mounting block 53 and the pressure plate 52. The round hole block 62 is inserted into the inner wall of the U-shaped block 66. By setting the U-shaped block 66, it is easy to quickly position the round hole block 62, and at the same time, it can make the fixation between the two round hole blocks 62, the pressure plate 52 and the mounting block 53 more stable.

[0033] Working principle: Place the wire connected to terminal 4 in the groove, push the pressure plate 52 so that it approaches the base plate 51. The pressure plate 52 will cause the rectangular plate 54 to slide on the inner wall of the rectangular tube 55, and at the same time, it will cause the mounting block 53 to compress the spring 57, causing the spring 57 to deform until the rubber plate 510 on one side of the pressure plate 52 and the base plate 51 abut against each other. At this time, the protrusion enters the groove, which can completely clamp the wire. Then rotate the bolt 56 so that one end of the bolt 56 abuts against one side of the rectangular plate 54, which can fix the pressure plate 52. In this way, the pressure plate 52 and the base plate 51 can provide auxiliary fixation for the wire. When the wire is subjected to external force, the connection part between the wire and the pressure plate 52 and the base plate 51 will be pulled first, and then the connection between the wire and terminal 4 will be pulled. This can reduce the pressure on the wire when it is pulled and help prevent the wire from coming off under the action of external force. Terminal 4; Rotate bolt 56 so that bolt 56 moves away from rectangular plate 54, then spring 57 will reset and automatically drive pressure plate 52 away from base plate 51, thus facilitating maintenance and other operations on the circuit; Insert the locking block 61 between mounting block 53 and pressure plate 52, and insert threaded pin 63 into the inner wall of round hole block 62, and round hole block 62 into the inner wall of U-shaped block 66; Rotate nut 64 so that the rubber pad on one side of nut 64 presses round hole block 62 until one side of the two round hole blocks 62 abuts against one side of round hole block 62 and pressure plate 52 respectively, thus fixing pressure plate 52 and two mounting blocks 53, and making pressure plate 52 removable, thus facilitating individual disassembly and maintenance of pressure plate 52; At the same time, one side of mounting block 53 can be disassembled individually, thus facilitating the placement or removal of the circuit between pressure plate 52 and base plate 51 through the space between mounting block 53 and pressure plate 52.
