Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a distribution radio frame. Background Technology

[0002] With the development of power equipment technology, distribution radio technology has emerged. Distribution radios can be used to install power equipment such as transformers. Through transformers and other power equipment, electrical energy transmitted from high-voltage transmission circuits can be drawn out for distribution to users.

[0003] In related technologies, fuses are usually installed on distribution transformer racks to protect the electrical equipment on the racks. The fuses and various electrical equipment, such as transformers, are connected by cables to form a current path. As electrical protection devices, fuses need to be inspected and replaced relatively frequently. When it is necessary to inspect and replace a fuse, a circuit breaker or switch is used to create an open circuit between the electrical equipment on the distribution transformer rack and the high-voltage transmission line. Grounding is installed at the open circuit location to prevent reverse power supply from the user side to the high-voltage transmission line, thus ensuring the safety of maintenance personnel during maintenance operations.

[0004] However, after the electrical equipment on the distribution substation is disconnected from the high-voltage transmission line through the above-mentioned operation method, although the residual charge in the electrical equipment can be released through grounding, the charge stored in the transformer's ground capacitance cannot be released. That is, a certain amount of charge is still stored in the transformer through the above method. Since the fuse and the transformer are interconnected through the cable and form a circuit, there is still a certain risk when maintenance personnel operate the fuse. In addition, the cable is usually only connected to the corresponding electrical equipment at both ends, that is, the cable is not completely fixed on the distribution substation and is suspended. Since there is a certain charge in the connection between the cable and the transformer, the swaying of the cable during operation will generate an induced electromotive force. The induced electromotive force and the residual charge are superimposed, thereby increasing the operational risk of the electrical equipment on the distribution substation. Summary of the Invention

[0005] Therefore, it is necessary to provide a distribution transformer rack to address the inherent risks of maintaining power equipment on the aforementioned distribution transformer rack, thereby eliminating the impact of residual charge and induced electromotive force on maintenance and improving maintenance safety.

[0006] A distribution frame, comprising:

[0007] Mounting rod;

[0008] The disconnect switch is connected to the mounting rod;

[0009] A fuse is connected to the mounting rod, and the fuse is electrically connected to the disconnecting switch via a connecting wire;

[0010] A first grounding terminal is disposed between the disconnecting switch and the fuse and is electrically connected to the connecting line. The first grounding terminal is used to ground the connecting line.

[0011] A transformer is connected to the mounting rod, and the transformer is electrically connected to the fuse;

[0012] The second grounding terminal is electrically connected to the fuse, and the second grounding terminal is used to ground the fuse.

[0013] In some embodiments, the second grounding terminal is integrally formed with one sidewall of the fuse; the distribution frame also includes an insulating cap that is detachably disposed on the periphery of the second grounding terminal.

[0014] In some embodiments, the aforementioned distribution frame further includes a plurality of connection components, at least one of the connection components being connected to the disconnecting switch, at least one of the connection components being connected to the fuse, each of the connection components being connected to either the disconnecting switch or the fuse, and both the disconnecting switch and the fuse being electrically connected to the connection line via the connection component.

[0015] In some embodiments, the connecting wire includes a conductor body, a connector, and a nut. The connector is located at the end of the conductor body, and the nut is fitted around the outer periphery of the conductor body and slidably connected to it. The connecting assembly includes a threaded seat and a conductive seat. The conductive seat is located in the middle of the threaded seat and has a insertion groove. The connector is inserted into the insertion groove, and the nut is threadedly connected to the threaded seat. When the nut is threadedly connected to the threaded seat, the nut and the threaded seat form a sealed cavity, and both the connector and the conductive seat are located within the sealed cavity.

[0016] In some embodiments, the disconnecting switch includes a fixed base and a rotating component. The fixed base is connected to the mounting rod, and one end of the rotating component is rotatably connected to the fixed base. The other end of the rotating component is provided with a conductive pin. The fixed base has a slot corresponding to the conductive pin. The rotating component rotates so that the conductive pin can be inserted into the slot. When the conductive pin is inserted into the slot, the side wall of the rotating component is in contact with the surface of the fixed base where the slot is located.

[0017] In some embodiments, the distribution frame further includes multiple insulating housings, which are respectively fitted around the periphery of the disconnecting switch and the fuse. Some of the insulating housings are integrated with their corresponding disconnecting switches, and other insulating housings are integrated with their corresponding fuses.

[0018] In some embodiments, the insulating shell is made of epoxy resin.

[0019] In some embodiments, the power distribution frame further includes an anti-reverse power supply device, which is connected to the mounting rod and disposed between the disconnecting switch and the fuse, wherein the disconnecting switch, the anti-reverse power supply device, and the fuse are electrically connected in sequence.

[0020] In some embodiments, the distribution frame further includes a lightning protection mechanism connected to the mounting rod and disposed between the fuse and the transformer, wherein the fuse, the lightning protection mechanism, and the transformer are electrically connected in sequence.

[0021] In some embodiments, the distribution frame also includes a support frame, through which the disconnecting switch, the fuse, and the transformer are all connected to the mounting rod.

[0022] The aforementioned distribution frame is equipped with mounting poles to facilitate the installation of various electrical equipment and to provide support for the high-voltage transmission lines. The high-voltage transmission lines, disconnecting switches, fuses, and transformers are electrically connected in sequence, creating a current flow from the high-voltage transmission lines to the transformer. Operating the disconnecting switch controls the connection between the relevant equipment on the distribution frame and the high-voltage transmission lines. The fuses blow when the current is too high, protecting the electrical equipment on the distribution frame from damage due to excessive current. The transformer is used to adjust the output voltage for power distribution. A first grounding terminal is located between the disconnecting switch and the fuse. In the event of reverse power supply, the reverse current can be conducted to the ground through the first grounding terminal, preventing reverse power supply from the user side to the high-voltage transmission lines. It also prevents the disconnecting switch from malfunctioning or experiencing high-voltage breakdown, thus preventing current from the high-voltage transmission lines from supplying current to the fuses during maintenance and improving the safety of maintenance operations. The second grounding terminal is connected to the fuse, which grounds the fuse and eliminates the influence of residual charge and induced potential on the fuse. That is, the current formed by residual charge and induced potential cannot flow through the fuse, thus improving the safety of maintenance operations. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] See Figure 1 and Figure 4 , Figure 1 A schematic diagram of the distribution radio rack in one embodiment of this application is shown. Figure 3A schematic diagram of the structure of a fuse in a distribution frame according to an embodiment of this application is shown. An embodiment of this application provides a distribution frame including a mounting rod 100, a disconnecting switch 200, a fuse 300, a first grounding terminal (not shown), a transformer 400, and a second grounding terminal 301. The disconnecting switch 200 is connected to the mounting rod 100, and the fuse 300 is also connected to the mounting rod 100. The fuse 300 and the disconnecting switch 200 are electrically connected via a connecting line 500. The first grounding terminal is located between the disconnecting switch 200 and the fuse 300 and is electrically connected to the connecting line 500. The first grounding terminal is used to ground the connecting line 500. The transformer 400 is connected to the mounting rod 100 and is electrically connected to the fuse 300. The second grounding terminal 301 is electrically connected to the fuse 300 and is used to ground the fuse 300.

[0036] The disconnector switch 200, fuse 300, and transformer 400 are all mounted on the mounting rod 100. The high-voltage transmission line can be installed on the mounting rod 100. The high-voltage transmission line, disconnector switch 200, fuse 300, and transformer 400 are electrically connected in sequence, so the current flows from the high-voltage transmission line to the transformer. For ease of understanding, the end into which the current flows into the power equipment is referred to as the input end, and the end into which the current outputs is referred to as the output end. The current output by the transformer 400 is used by the user; therefore, the output end of the transformer 400 is referred to as the user side. By adjusting the closing and opening of the disconnector switch 200, a disconnection point can be formed between the high-voltage transmission line and the transformer 400, isolating the fuse 300, which needs maintenance, from the high-voltage transmission line, thus improving the safety of fuse 300 maintenance. The fuse 300 can melt under high current, creating an open circuit between the high-voltage transmission line and the transformer 400, protecting the relevant power equipment from burning out under high current conditions. The first grounding terminal is located between the disconnector switch 200 and the fuse 300, grounding the input terminal of the fuse 300. When a back-supply occurs due to high voltage on the user side, the back-supply current can be conducted to the ground, preventing it from entering the high-voltage transmission line through the disconnector switch and causing damage to equipment or grid impact. It also prevents the high-voltage transmission line from forming a circuit with the fuse 300. The second grounding terminal 301 is connected to the fuse 300. In the event of a blown fuse 300, it can conduct residual charge and induced current in the circuit formed by the transformer 400 and the fuse 300 to the ground, improving the safety of maintenance personnel during maintenance operations.

[0037] It should be noted that since the function of the disconnector 200 is to create a break in the circuit, it does not have the function of cutting off current or extinguishing arc. Therefore, when a high voltage is generated on the user side, the reverse power supply current can enter the high voltage transmission line through the disconnector 200. Setting up the disconnector 200 is the preferred solution in the prior art based on safety, system protection and economic considerations.

[0038] In some preferred embodiments, the mounting rod 100 is vertically fixed to a supporting surface such as the ground. High-voltage transmission lines (high-voltage cables, wires, etc.) are connected to the top of the mounting rod 100. The disconnecting switch 200, fuse 300, and transformer 400 are sequentially connected to the mounting rod 100 from top to bottom, with the disconnecting switch 200, fuse 300, and transformer 400 spaced apart, thus facilitating maintenance by repair personnel. The first grounding terminal is located at the output end of the disconnecting switch 200 or the input end of the fuse 300, ensuring that the first grounding terminal is fixed and does not sway with the connecting wire 500, preventing it from easily falling off.

[0039] With the above settings, the second grounding terminal 301 can eliminate the residual charge that may exist between the transformer 400 and the fuse 300, as well as the induced electromotive force generated by the cable. The first grounding terminal can prevent reverse power supply from affecting the normal transmission of the high-voltage transmission line, thereby eliminating the risk of electric shock that may exist when repairing the fuse 300 or the transformer 400, and improving the safety of the repair operation.

[0040] like Figure 1 and Figure 4 As shown, in some embodiments, the second grounding terminal 301 is integrally formed with one side wall of the fuse 300; the distribution frame also includes an insulating cap 310, which is detachably installed on the outer periphery of the second grounding terminal 301. Thus, when grounding is not required, the insulating cap 310 can be installed on the outer periphery of the second grounding terminal 301 to prevent rainwater contact and rust, and to prevent birds and other animals from contacting the second grounding terminal 301 and causing leakage; when grounding is required, the insulating cap 310 can be removed to connect the second grounding terminal 301 to the grounding wire, thereby achieving grounding. Through the above design, the second grounding terminal 301 is protected from rust and damage when not in use, and the installation and removal operations are simple and quick, facilitating on-site operation.

[0041] In some embodiments, the aforementioned distribution frame further includes a plurality of connection components 600, at least one connection component 600 being connected to a disconnecting switch 200, at least one connection component 600 being connected to a fuse 300, each connection component 600 being connected to either the disconnecting switch 200 or the fuse 300, both of which are electrically connected to a connection line 500 via the connection component 600.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in some preferred embodiments, one connecting component 600 is located at the output end of the disconnecting switch 200, and the other connecting component 600 is located at the input end of the fuse 300. One end of the connecting line 500 is connected to the connecting component 600 on the disconnecting switch 200, and the other end of the connecting line 500 is connected to the connecting component 600 on the fuse 300, so that the disconnecting switch 200 and the fuse 300 are connected. By setting the connecting component 600, a corresponding connection point can be provided for the connecting line 500, which facilitates the installation of the connecting line 500.

[0043] like Figure 1 and Figure 5 As shown, in some embodiments, the connecting wire 500 includes a conductor body 510, a connector 520, and a nut 530. The connector 520 is located at the end of the conductor body 510, and the nut 530 is sleeved on the outer periphery of the conductor body 510 and slidably connected to it. The connecting assembly 600 includes a threaded seat 610 and a conductive seat 620. The conductive seat 620 is located in the middle of the threaded seat 610 and has a insertion groove 621. The connector 520 is inserted into the insertion groove 621. The nut 530 is threadedly connected to the threaded seat 610. When the nut 530 is threadedly connected to the threaded seat 610, the nut 530 and the threaded seat 610 form a sealed cavity (not shown in the figure), and both the connector 520 and the conductive seat 620 are located within the sealed cavity.

[0044] Both ends of the conductor body 510 are provided with connectors 520. A nut 530 is fitted around the outer circumference of the conductor body 510 and can slide along the length of the conductor body 510, allowing the nut 530 to slide to the connector 520 so that the connector 520 is located within the cavity in the middle of the nut 530. A threaded seat 610 is annularly disposed around the outer circumference of the conductive seat 620, meaning the conductive seat 620 is located within the cavity in the middle of the threaded seat 610. When the connector 520 is inserted into the insertion slot 621 in the middle of the conductive seat 620, the nut 530 can move to the corresponding position on the threaded seat 610. At this time, rotating the nut 530 allows for a threaded connection between the nut 530 and the threaded seat 610. Figure 5 As shown, after the nut 530 is threadedly connected to the threaded seat 610, the nut 530 and the threaded seat 610 can form a sealed cavity, allowing the connector 520 and the conductive base 620 to be located within the sealed cavity. With this configuration, under normal operating conditions, i.e., when the disconnector 200 and the fuse 300 are connected via the connecting wire 500, the exposed conductive base 620 and connector 520 are both located within the sealed cavity. This prevents the conductive base 620 and connector 520 from being exposed to air and corroded by air and rainwater, thus improving their service life and preventing leakage. Furthermore, the threaded engagement of the nut 530 and the threaded seat 610 ensures a stable connection between the connecting wire 500 and the connecting assembly 600.

[0045] In addition, the transformer 400 and other electrical equipment (surge arresters, distribution boxes, etc.) installed on the mounting pole 100 can also be equipped with connection components 600. The electrical equipment installed on the mounting pole 100 can be connected to each other through the connection components 600 and the connection lines 500, thereby improving the connection stability of each electrical device. This will not be described in detail here.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the disconnect switch 200 includes a fixed base 210 and a rotating member 220. The fixed base 210 is connected to the mounting rod 100, and one end of the rotating member 220 is rotatably connected to the fixed base 210. The other end of the rotating member 220 is provided with a conductive pin 221. The fixed base 210 has a slot 211 corresponding to the conductive pin 221. The rotating member 220 rotates so that the conductive pin 221 can be inserted into the inside of the slot 211. When the conductive pin 221 is inserted into the inside of the slot 211, the side wall of the rotating member 220 is in contact with the surface of the fixed base 210 where the slot 211 is provided.

[0047] The fixed base 210 is fixedly connected to the mounting rod 100. One end of the rotating member 220 is rotatably connected to the fixed base 210. The rotating member 220 rotates relative to the fixed base 210, allowing the other end of the rotating member 220 to move the conductive pin 221 closer to or away from the slot 211. When the conductive pin 221 is inserted into the slot 211, the disconnecting switch 200 is in the closed state; when the conductive pin 221 is disengaged from the slot 211, the disconnecting switch 200 is in the open state. Figure 3 As shown, the conductive pin 221 protrudes from the surface of the rotating member 220 corresponding to the fixed seat 210, and the slot 211 is formed on the surface of the fixed seat 210. Therefore, when the conductive pin 221 is inserted into the slot 211, the surface of the rotating member 220 with the conductive pin 221 abuts against the surface of the fixed seat 210 with the slot 211, preventing rainwater and other impurities from directly contacting the conductive pin 221 through the gap between the rotating member 220 and the fixed seat 210. This design improves the sealing effect at the connection of the disconnector switch 200, preventing leakage or damage caused by water ingress and effectively extending the service life of the disconnector switch 200.

[0048] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the distribution frame also includes multiple insulating housings 700, which are correspondingly fitted around the outer periphery of the disconnector switch 200 and the fuse 300. Some insulating housings 700 are integrated with their corresponding disconnector switches 200, while others are integrated with their corresponding fuses 300. Since both the disconnector switch 200 and the fuse 300 are integrated with the insulating housings 700, maintenance personnel can directly replace the fuse 300 and the disconnector switch 200 as a whole during installation and removal without additional installation and removal of the insulating housings 700, effectively simplifying the operation.

[0049] In some preferred embodiments, an insulating housing 700 is fitted around the periphery of the disconnector switch 200, with the inner wall of the insulating housing 700 fitting against the outer wall of the disconnector switch 200. Similarly, another insulating housing 700 is fitted around the periphery of the fuse 300, with the inner wall of the insulating housing 700 fitting against the outer wall of the fuse 300. This can prevent maintenance personnel or animals such as birds from directly contacting the conductive parts of the disconnector switch 200 and the fuse 300, thereby improving safety in use.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the insulating shell 700 is made of epoxy resin.

[0051] Because epoxy resin material has good insulation and corrosion resistance, the above-mentioned settings can ensure the insulation and service life of the insulating shell 700.

[0052] Furthermore, in addition to the disconnector switch 200 and the fuse 300, the external of other electrical equipment (such as the transformer 400) in the distribution frame can be equipped with an insulating shell 700 to improve the safety of each electrical device and prevent corrosion.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the power distribution frame also includes a backflow prevention device 800, which is connected to the mounting rod 100 and located between the disconnecting switch 200 and the fuse 300. The disconnecting switch 200, the backflow prevention device 800, and the fuse 300 are electrically connected in sequence.

[0054] In some preferred embodiments, the anti-reverse power supply device 800 is located at the output terminal of the disconnector switch 200. The anti-reverse power supply device 800 can detect the direction of the current flowing through it to determine whether a reverse power supply situation has occurred. If a reverse power supply situation occurs, the anti-reverse power supply device 800 can cut off the path between it and the high-voltage transmission line, preventing reverse power supply to the high-voltage transmission line. It should be noted that the first grounding terminal is located between the anti-reverse power supply device 800 and the fuse 300. When the first grounding terminal is reliably grounded, the reverse power supply current will be conducted to the ground through the first grounding terminal. At this time, the anti-reverse power supply device 800 will not detect the reverse power supply current. When the first grounding terminal is unreliable, the anti-reverse power supply device 800 can detect the reverse power supply current and disconnect from the high-voltage transmission line. Through the above settings, reverse power supply to the high-voltage transmission line can be prevented in the event of grounding failure, thus improving safety.

[0055] like Figure 1 As shown, in some embodiments, the distribution frame also includes a lightning protection mechanism 900, which is connected to the mounting rod 100 and positioned between the fuse 300 and the transformer 400. The fuse 300, the lightning protection mechanism 900, and the transformer 400 are electrically connected in sequence. Through this arrangement, the lightning protection mechanism 900 is used to discharge the current from lightning strikes, ensuring the normal operation of other electrical equipment.

[0056] like Figure 1 As shown, in some embodiments, the distribution frame also includes a support frame 110, and the disconnecting switch 200, fuse 300 and transformer 400 are all connected to the mounting rod 100 through the support frame 110.

[0057] The support frame 110 can be plate-shaped or rod-shaped. The support frame 110 is fixed to the mounting rod 100 by bolts. The disconnecting switch 200, fuse 300, and transformer 400 are all fixed to the support frame 110 by bolts. With the above arrangement, the disconnecting switch 200, fuse 300, and transformer 400 can be securely connected to the mounting frame 110.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
