Description

Technical Field

[0001] This utility model relates to the field of microcomputer excitation device technology, and in particular to a microcomputer excitation device for low-voltage units. Background Technology

[0002] A microprocessor-based excitation device is an intelligent device based on microprocessor technology. It is mainly used to regulate and control the excitation current of low-voltage generator sets, thereby ensuring the stable operation of the power system and power quality. The microprocessor-based excitation device is generally a microprocessor-based excitation controller, which consists of the microprocessor-based excitation controller body and terminals. When using the microprocessor-based excitation device, the terminals are fixed to the low-voltage generator set with wires. Then, the microprocessor-based excitation controller body is started. Through voltage transformers and current transformers, parameters such as the generator's terminal voltage and stator current are collected in real time. The analog signals are converted into digital signals and input to the microprocessor for calculation. Then, the PID control algorithm is used to dynamically calculate the required excitation current adjustment. By adjusting the phase angle of the trigger pulse of the thyristor rectifier bridge, the output current of the excitation power unit is changed, thereby stabilizing the generator voltage or grid voltage.

[0003] In their daily work, the inventors discovered that when using the microcomputer excitation device, the connection between the microcomputer excitation device and the low-voltage generator set is fixed through the wires connected to the low-voltage generator set and the terminal. Since there are many wires connected to the terminal, and the microcomputer excitation device does not have a mechanism to organize the wires, the wires are very messy, which may make it difficult to maintain the microcomputer excitation device. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the microcomputer excitation device is connected to the low-voltage generator set through the wires connected to the low-voltage generator set and fixed to the terminal. Since there are many wires connected to the terminal, and the microcomputer excitation device does not have a mechanism to organize the wires, the wires are very messy, which makes it difficult to maintain the microcomputer excitation device. Therefore, the proposed microcomputer excitation device for low-voltage generator sets is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-voltage generator microcomputer excitation device, comprising a microcomputer excitation controller body, wherein a terminal block and a cable management assembly are fixedly connected to the back of the microcomputer excitation controller body, and an auxiliary installation assembly is provided on one side of the microcomputer excitation controller body. The cable management assembly includes a mounting plate fixedly connected to the back of the microcomputer excitation controller body, a first organizing block is fixedly connected to the front of the mounting plate, a fixing post is fixedly connected to the front of the first organizing block, the arc surface of the fixing post is provided with a protrusion, a second organizing block is provided on the front of the first organizing block, and the fixing post is inserted into the second organizing block.

[0006] The effect achieved by the above components is as follows: by setting up the cable management component, when it is necessary to fix the wire to the terminal, the wire is dragged so that it is placed in the semi-circular groove on the first management block on the mounting plate, and then the second management block is dragged so that it is locked onto the fixing post, thereby fixing the wire and thus achieving the goal of organizing the wire as much as possible.

[0007] Preferably, the inner walls of the first and second sorting blocks are provided with clamping blocks, and the arc surface of the clamping blocks is fixedly connected with a first spring. The first spring is fixed to the first sorting block, and the first spring on the other side is fixed to the second sorting block.

[0008] The effect achieved by the above components is as follows: by setting up clamping blocks and a first spring, the wire is placed into the two clamping blocks, so that the first spring is squeezed, causing its reverse force to push the clamping blocks, thereby further fixing the wire.

[0009] Preferably, a sphere is slidably inserted into the arc surface of the fixing column, a second spring is fixedly connected between the sphere and the fixing column, and an auxiliary surface is provided on the inner wall of the second sorting block.

[0010] The effect achieved by the above components is as follows: dragging the second sorting block causes the ball to contact the auxiliary surface, causing the ball to retract into the fixed column, the second spring is compressed, and dragging the second sorting block continues. After the first sorting block and the second sorting block contact, the first spring returns to its original position, causing the ball to be inserted into the second sorting block, thereby further fixing the fixed column and the second sorting block.

[0011] Preferably, a pull rope is fixedly connected to the arc surface of the sphere, and the pull rope passes through the fixed column.

[0012] The effect achieved by the above components is as follows: pulling the rope causes the ball to retract to the fixed post, and then the second sorting block is dragged to disassemble it.

[0013] Preferably, a rubber pad is fixedly connected to the inner arc surface of the clamping block, and the surface of the rubber pad is provided with anti-slip stripes.

[0014] The effect achieved by the above components is to increase the friction between the wire and the clamping block by setting the rubber pad.

[0015] Preferably, the auxiliary installation component includes an auxiliary ring fixedly connected to one side of the microcomputer excitation controller body, and the arc surface of the auxiliary ring is provided with protrusions.

[0016] The effect achieved by the above components is as follows: when it is necessary to install the microcomputer excitation controller body onto the cabinet, drag the microcomputer excitation controller body so that the auxiliary ring is inserted into the cabinet, so that the mounting holes on the microcomputer excitation controller body are aligned with the mounting holes on the cabinet, and then tighten the screws to fix it.

[0017] Preferably, a trapezoidal block is slidably inserted into the arc surface of the auxiliary ring, and a third spring is fixedly connected between the trapezoidal block and the auxiliary ring.

[0018] The effect achieved by the above components is as follows: by setting the trapezoidal block, the microcomputer excitation controller body is dragged so that the auxiliary ring is inserted into the cabinet. The trapezoidal block contacts the cabinet and is retracted into the auxiliary ring, so that the third spring is compressed. After the auxiliary ring is fully inserted into the cabinet, the third spring is reset, so that the trapezoidal block is inserted into the cabinet.

[0019] Preferably, one end of the trapezoidal block is fixedly connected to a pull wire, which passes through the microcomputer excitation controller body.

[0020] The effect achieved by the above components is as follows: pulling the pull wire causes the trapezoidal block to retract into the auxiliary ring, and then the microcomputer excitation controller body is dragged for disassembly.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a wire management component, when it is necessary to manage the wires that need to be fixed to the terminal, the wire is dragged and placed into the semi-circular groove on the first management block on the mounting plate. Then, the second management block is dragged and locked onto the fixing post, thereby fixing the wire. This achieves the goal of organizing the wires as much as possible, solving the problem that since the microcomputer excitation device is connected to the low-voltage generator set, the wires connected to the low-voltage generator set are fixed to the terminal. Because there are many wires connected to the terminal, and the microcomputer excitation device does not have a mechanism for organizing the wires, the wires are very messy, which may make it difficult to maintain the microcomputer excitation device.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: the microcomputer excitation device for low-voltage units includes a microcomputer excitation controller body 1, a wiring terminal 4 and a cable management component 2 are fixedly connected to the back of the microcomputer excitation controller body 1, and an auxiliary installation component 3 is provided on one side of the microcomputer excitation controller body 1.

[0029] The following section will explain the specific settings and functions of cable management component 2 and auxiliary installation component 3.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the cable management assembly 2 includes a mounting plate 21 fixedly connected to the back of the microcomputer excitation controller body 1. A first organizing block 22 is fixedly connected to the front of the mounting plate 21, and a fixing post 24 is fixedly connected to the front of the first organizing block 22. The arc surface of the fixing post 24 is provided with a protrusion. A second organizing block 23 is provided on the front of the first organizing block 22. The fixing post 24 is inserted into the second organizing block 23. By setting the cable management assembly 2, when it is necessary to fix the wire to the terminal 4, the wire is dragged so that it is placed on the mounting plate 21. The wire is placed into the semi-circular groove on the first organizing block 22, and then the second organizing block 23 is dragged to lock onto the fixing post 24, thereby fixing the wire and arranging it as much as possible. The inner walls of the first organizing block 22 and the second organizing block 23 are provided with clamping blocks 28. The arc surface of the clamping block 28 is fixedly connected to the first spring 29. The first spring 29 is fixed to the first organizing block 22, and the other side of the first spring 29 is fixed to the second organizing block 23. By setting the clamping blocks 28 and the first spring 29, the wire is placed into the two clamping blocks 28. Inside, the first spring 29 is compressed, causing it to push the clamping block 28 with a reverse force, thereby further fixing the wire. A ball 25 is slidably inserted into the arc surface of the fixing post 24. A second spring 26 is fixedly connected between the ball 25 and the fixing post 24. An auxiliary surface 210 is opened on the inner wall of the second sorting block 23. Dragging the second sorting block 23 causes the ball 25 to contact the auxiliary surface 210, causing the ball 25 to retract into the fixing post 24. The second spring 26 is compressed. Continuing to drag the second sorting block 23, the first sorting block 22 and the second sorting block 23... After the second sorting block 23 contacts, the first spring 29 returns to its original position, causing the ball 25 to be inserted into the second sorting block 23, thereby further fixing the fixing post 24 and the second sorting block 23. The arc surface of the ball 25 is fixedly connected to a pull rope 27, which passes through the fixing post 24. Pulling the pull rope 27 causes the ball 25 to retract to the fixing post 24. Then, the second sorting block 23 is dragged for disassembly. The inner arc surface of the clamping block 28 is fixedly connected to a rubber pad, and the surface of the rubber pad is provided with anti-slip stripes. By setting the rubber pad, the friction between the wire and the clamping block 28 is increased.

[0031] Reference Figure 4As shown in this embodiment: the auxiliary installation component 3 includes an auxiliary ring 31 fixedly connected to one side of the microcomputer excitation controller body 1. The arc surface of the auxiliary ring 31 is provided with a protrusion. When it is necessary to install the microcomputer excitation controller body 1 onto the cabinet, the microcomputer excitation controller body 1 is dragged so that the auxiliary ring 31 is inserted into the cabinet, so that the mounting hole on the microcomputer excitation controller body 1 is aligned with the mounting hole on the cabinet. Then, the screws are tightened to fix it. A trapezoidal block 32 is slidably inserted into the arc surface of the auxiliary ring 31. A third spring 3 is fixedly connected between the trapezoidal block 32 and the auxiliary ring 31. 3. By setting the trapezoidal block 32, drag the microcomputer excitation controller body 1 so that the auxiliary ring 31 is inserted into the cabinet. The trapezoidal block 32 contacts the cabinet and is retracted into the auxiliary ring 31, which compresses the third spring 33. After the auxiliary ring 31 is fully inserted into the cabinet, the third spring 33 resets, so that the trapezoidal block 32 is inserted into the cabinet. One end of the trapezoidal block 32 is fixedly connected to a pull wire 34, which passes through the microcomputer excitation controller body 1. Pulling the pull wire 34 causes the trapezoidal block 32 to retract into the auxiliary ring 31. Then, drag the microcomputer excitation controller body 1 to disassemble it.

[0032] Working principle:

[0033] When using the microprocessor-based excitation device, connect terminal 4 to the low-voltage generator set with a wire. Then, start the microprocessor-based excitation controller body 1 (the selected microprocessor-based excitation controller model is Guoli Xuzhen GDF-2). The device collects parameters such as the generator's terminal voltage and stator current in real time through voltage and current transformers, converts the analog signals into digital signals, and inputs them into the microprocessor for calculation. Then, a PID control algorithm is used to dynamically calculate the required excitation current adjustment. By adjusting the trigger pulse phase angle of the thyristor rectifier bridge, the output current of the excitation power unit is changed, thereby stabilizing the generator voltage or the grid voltage. When it is necessary to fix the wire to terminal 4, drag the wire so that it is placed in the semi-circular groove on the first organizing block 22 on the mounting plate 21. Then drag the second organizing block 23 so that it is locked onto the fixing post 24, thereby fixing the wire and thus organizing the wire as much as possible. By setting the clamping block 28 and the first spring 29, the wire is placed in the two clamping blocks 28, so that the first spring 29 is squeezed, and its reverse force pushes the clamping block 28, thereby further fixing the wire. Dragging the second organizing block 23 makes the ball 25 contact the auxiliary surface 210, so that the ball 25 retracts. Back inside the fixed column 24, the second spring 26 is compressed, and the second sorting block 23 continues to be dragged. After the first sorting block 22 and the second sorting block 23 come into contact, the first spring 29 returns to its original position, causing the ball 25 to engage with the second sorting block 23, thereby further securing the fixed column 24 and the second sorting block 23. Pulling the pull rope 27 causes the ball 25 to retract into the fixed column 24, and then the second sorting block 23 is dragged for disassembly. By setting a rubber pad, the friction between the wire and the clamping block 28 is increased. When it is necessary to install the microcomputer excitation controller body 1 onto the cabinet, dragging the microcomputer excitation controller body 1 causes the auxiliary ring 31 to engage. Insert the microprocessor excitation controller body 1 into the cabinet, aligning the mounting holes on the microprocessor excitation controller body 1 with the mounting holes on the cabinet. Then, tighten the screws to secure it. By setting the trapezoidal block 32, drag the microprocessor excitation controller body 1 so that the auxiliary ring 31 is inserted into the cabinet. The trapezoidal block 32 contacts the cabinet and is retracted into the auxiliary ring 31, compressing the third spring 33. After the auxiliary ring 31 is fully inserted into the cabinet, the third spring 33 resets, allowing the trapezoidal block 32 to be inserted into the cabinet. Pull the pull cable 34 to retract the trapezoidal block 32 into the auxiliary ring 31. Then, drag the microprocessor excitation controller body 1 to disassemble it.
