Description

Technical Field

[0001] This utility model relates to the field of power distribution network equipment, and in particular to a low-power power distribution terminal based on capacitor power supply. Background Technology

[0002] In power distribution networks, pole-mounted circuit breakers are common devices used to control and protect the safe operation of the grid. With technological advancements, integrated primary and secondary pole-mounted circuit breakers are becoming increasingly popular. These devices integrate more intelligent functions, enabling them to perform more complex monitoring and control tasks. To adapt to this trend, low-power distribution terminal technology based on capacitor power supply has emerged. It aims to solve the problems of high power consumption and limited power supply capacity in traditional distribution terminals, thus meeting the operational requirements of new pole-mounted circuit breakers.

[0003] Existing devices of this type have a wiring structure at the bottom of the terminal body for easy wiring connection. To prevent friction damage between the connecting wire and the opening of the terminal body, a flexible tube is installed at the opening. However, the flexible tube cannot be adjusted according to the actual wire insertion gap, resulting in a large gap between the connecting wire and the flexible tube, making the connecting wire easy to shake, which may cause the connection between the connecting wire and the terminal body to loosen. In view of this, this solution proposes a low-power distribution terminal based on capacitor power to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-power distribution terminal based on capacitor power supply to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-power distribution terminal based on capacitor power supply, comprising a feeder terminal body, wherein a cabinet door is hinged to the front of the feeder terminal body, and further comprising:

[0006] The installation mechanism, in which multiple sets of the installation mechanism are respectively set on the top and bottom of the feeder terminal body, is used for wall mounting of the feeder terminal body;

[0007] A wire threading mechanism is inserted and connected to the bottom of the feeder terminal body. The wire threading mechanism includes a threading tube and an adjusting tube. One end of the threading tube is inserted and connected to the bottom of the feeder terminal body, and the other end of the threading tube is connected to the adjusting tube. A wire clamping part is provided at the connection between the threading tube and the adjusting tube.

[0008] The clamping part includes multiple sets of extrusion balls and multiple sets of extrusion strips. One end of each set of extrusion strips is inserted around and connected to the inner wall of the insertion tube, and the wall thickness of the extrusion strips gradually increases along the direction from the adjustment tube to the insertion tube.

[0009] Preferably, one side of the cabinet door is hinged to the front of the feeder terminal body, and a lock is provided between the other side of the cabinet door and the front of the feeder terminal body.

[0010] Preferably, a control unit is provided at the top of the feeder terminal body and through the cabinet door. The control unit is used for monitoring, controlling and handling the operation of the power distribution line. A power module is provided at the bottom of the feeder terminal body and through the cabinet door. The power module is used for managing and distributing the input voltage and charging and monitoring the status of the battery.

[0011] Preferably, the installation mechanism includes an installation plate, and multiple sets of installation plates are fixedly connected to the top and bottom of the feeder terminal body, respectively. The installation plate has a mounting hole in the middle and fixing holes on both sides.

[0012] Preferably, the end of the insertion tube away from the regulating tube is fixedly connected to a connecting pipe, the connecting pipe is inserted into the bottom of the feeder terminal body, and the end of the connecting pipe away from the insertion tube is fixedly connected to an installation plate.

[0013] Preferably, the end of the insertion tube away from the connecting tube is fixedly connected to a threaded tube head, and one end of the adjusting tube is provided with a threaded groove, with the threaded tube head threadedly inserted into the threaded groove.

[0014] Preferably, the clamping portion includes:

[0015] Extrusion balls, multiple sets of which are circumferentially interlocked and connected to the middle of the inner wall of the interlocking tube;

[0016] The extrusion strip and multiple sets of extrusion balls are connected to the inner wall of the insertion tube in a circular and interlocking manner. The end of the multiple sets of extrusion strips away from the insertion tube is fixedly connected to the inner wall of the adjustment tube. The extrusion balls are used to cooperate with the movement of the multiple sets of extrusion strips to make them press and move closer together.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention features a threading mechanism that combines a threading tube and an adjusting tube, with a clamping part at their connection point. After the connecting wire passes through the threading tube, adjusting the distance between the threading tube and the adjusting tube causes the adjusting tube to move the clamping part within the inner wall of the threading tube, thereby squeezing and clamping the connecting wire inside the threading tube. This prevents the connecting wire from easily shaking and ensures the stability of the connection between the connecting wire and the terminal body. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: This utility model provides the following... Figure 1-3 The low-power distribution terminal based on capacitor power shown includes a feeder terminal body 1. A cabinet door 2 is hinged to the front of the feeder terminal body 1. One side of the cabinet door 2 is hinged to the front of the feeder terminal body 1, and a lock 3 is provided between the other side of the cabinet door 2 and the front of the feeder terminal body 1.

[0027] It should be noted that the electrical components inside the feeder terminal body 1 can be set and adjusted through the cabinet door 2. One end of the cabinet door 2 is hinged to the feeder terminal body 1 using a hinge structure, and the other end of the cabinet door 2 is locked using a lock 3.

[0028] Specifically, a control unit 4 is installed at the top of the feeder terminal body 1 and through the cabinet door 2. The control unit 4 is used for monitoring, controlling and handling the operation of the power distribution line. A power module 5 is installed at the bottom of the feeder terminal body 1 and through the cabinet door 2. The power module 5 is used for managing and distributing the input voltage and charging and monitoring the status of the battery.

[0029] It should be noted that the control unit 4 accounts for about 30% of the total power consumption of the machine. It consists of several circuits including main control, remote signaling, remote control and sampling. The main control MCU chip is selected as STM32F407ZGT6. It uses a low power operation mode and 5VDC power supply to eliminate the power loss in the 24VDC / 5VDC voltage conversion process, which can effectively reduce the power consumption of the core unit.

[0030] Power module 5 is responsible for managing and distributing various input voltages, supplying power to all modules of the system with output voltage, charging the battery, and monitoring its status. Two input voltage channels are designed: 24VAC from the capacitor, and different battery charging currents are designed to reduce battery charging power consumption. A boost converter is used to reduce the operating voltage of the supercapacitor, improving the utilization rate of the capacitor's energy storage and extending the standby time of the power supply in the event of power failure. Based on the relationship between the minimum operating voltage of the supercapacitor and its remaining energy, the minimum effective operating voltage of the supercapacitor is determined. Combined with the expected output power of the converter and the standby time in the event of power failure, the capacity of the supercapacitor is further determined.

[0031] Also includes:

[0032] Installation mechanism: Multiple installation mechanisms are respectively set at the top and bottom of the feeder terminal body 1. The installation mechanism is used for wall mounting of the feeder terminal body 1.

[0033] Specifically, the installation mechanism includes an installation plate 6. Multiple sets of installation plates 6 are fixedly connected to the top and bottom of the feeder terminal body 1, respectively. The installation plate 6 has a mounting hole 601 in the middle and fixing holes 602 on both sides.

[0034] It should be noted that, through the installation of the mounting plate 6, the feeder terminal body 1 can be wall-mounted using the mounting holes 601. Then, the mounting plate 6 can be fixed at the mounting position by inserting screws through the fixing holes 602, thereby completing the fixation of the feeder terminal body 1.

[0035] Example 2: This utility model provides the following... Figure 4 and Figure 5 The wiring mechanism shown is applied to the low-power distribution terminal based on capacitor power supply in Embodiment 1. The wiring mechanism is inserted and connected to the bottom of the feeder terminal body 1. The wiring mechanism includes a insertion tube 7 and an adjustment tube 8. One end of the insertion tube 7 is inserted and connected to the bottom of the feeder terminal body 1, and the other end of the insertion tube 7 is connected to the adjustment tube 8. A wire clamping part is provided at the connection between the insertion tube 7 and the adjustment tube 8.

[0036] Specifically, the end of the insertion tube 7 away from the regulating tube 8 is fixedly connected to the connecting tube 701, which is inserted into the bottom of the feeder terminal body 1, and the end of the connecting tube 701 away from the insertion tube 7 is fixedly connected to the mounting plate 702.

[0037] It should be noted that the connection of the insertion tube 7 to the bottom of the feeder terminal body 1 is achieved by the connecting pipe 701. Therefore, in the structural design of the feeder terminal body 1, a connection hole is opened at the bottom. After the connecting pipe 701 is inserted and connected, it can be fixed by the mounting plate 702, or it can be left unfixed so that the insertion tube 7 can rotate.

[0038] Furthermore, a threaded tube head 703 is fixedly connected to the end of the insertion tube 7 away from the connecting tube 701, and a threaded groove is opened at one end of the adjusting tube 8, with the threaded tube head 703 threadedly inserted into the threaded groove.

[0039] It should be noted that by threading the threaded tube head 703 into the threaded groove, the distance between the insertion tube 7 and the adjustment tube 8 can be adjusted by rotating the adjustment tube 8.

[0040] Specifically, the clamping part includes multiple sets of extrusion balls 704 and multiple sets of extrusion strips 801. One end of the multiple sets of extrusion strips 801 is wrapped around and inserted into the inner wall of the insertion tube 7, and the wall thickness of the extrusion strips 801 gradually increases along the direction from the adjusting tube 8 to the insertion tube 7.

[0041] Multiple sets of extrusion balls 704 are interlocked and connected around the middle of the inner wall of the insertion tube 7. Multiple sets of extrusion strips 801 are fixedly connected to the inner wall of the adjusting tube 8 at the end away from the insertion tube 7. The extrusion balls 704 are used to cooperate with the movement of the multiple sets of extrusion strips 801 to make them press and move closer together.

[0042] It should be noted that by utilizing the gradually changing wall thickness of the extrusion strip 801, when the connection distance between the adjusting tube 8 and the insertion tube 7 changes, the adjusting tube 8 will drive the extrusion strip 801 away from the insertion tube 7. At this time, after being squeezed by the extrusion ball 704, the extrusion strip 801 gradually approaches the middle of the insertion tube 7, thereby compressing the space in the middle of the insertion tube 7, so that the connecting line inserted in the middle of the insertion tube 7 can be squeezed.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
