[0002] A medium-voltage switchgear is a type of electrical equipment specifically designed for medium-voltage power distribution. It is mainly used to control, protect, and monitor medium-voltage circuits in power systems, playing a crucial role in the power system. It can protect against overload, short circuit, and grounding faults in the power system, thereby ensuring the safe and stable operation of the power system. It can realize functions such as incoming and outgoing lines, busbar connections, and reactive power compensation in the power system. Its main application areas include distribution substations, industrial and mining enterprises, and high-rise buildings.

[0003] The main step-down medium-voltage switchgear consists of circuit breakers, disconnecting switches, grounding switches, fuses, etc. Circuit breakers and disconnecting switches will cut off the circuit when a circuit fault occurs. Grounding switches are used to connect equipment or cables to the ground and introduce fault current into the ground. They are used to cut off the circuit when the current in the circuit exceeds the specified value. However, since a large number of components are installed inside the main step-down medium-voltage switchgear, and multiple busbars are connected to the outside of each component, the wiring harness inside the cabinet will be messy, making it inconvenient to find, replace and repair the wiring harness later. Utility Model Content

[0004] The purpose of this utility model is to provide a main step-down medium-voltage switchgear with a busbar cable management structure to solve the problem mentioned in the background art where a large number of components are installed inside the main step-down medium-voltage switchgear, and multiple busbars are connected to the outside of each component, resulting in messy wiring harnesses inside the switchgear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main step-down switchgear with a busbar cable management structure, comprising a cabinet, a guide adjustment rail and a cable management frame, wherein the cabinet has a heat dissipation groove inside, and a protective door is connected to one side of the cabinet, and a handle is connected to one side of the protective door;

[0006] The cabinet is equipped with a guide adjustment rail, and an adjustment block is inserted into the guide adjustment rail. Both the guide adjustment rail and the adjustment block have threaded grooves. Both the adjustment block and the guide adjustment rail are equipped with connecting bolts. The adjustment block is connected to one end of the connecting arm through a pin. The other end of the connecting arm has symmetrically opened mounting grooves. Both mounting grooves are connected to connecting springs, and positioning blocks are connected to the sides of the two connecting springs that are far apart. A cable management frame is provided on the outside of the connecting arm. The cable management frame has positioning holes inside, and the positioning blocks are inserted into the positioning holes on the adjacent side.

[0007] Preferably, the cable management frame has a connecting groove inside, and the side of the connecting arm away from the guide adjustment track is rotatably connected to the connecting groove through a positioning block.

[0008] Preferably, the threaded grooves are equidistantly spaced inside the guide adjustment track, and the positioning holes are symmetrically spaced inside the wire frame.

[0009] Preferably, the cable management frame is rotatably connected to the cable management blocks through a slot, and the cable management blocks are equidistantly arranged inside the cable management frame.

[0010] Preferably, the top of the cable management block is connected to an adjusting gear, and the outer side of the adjusting gear meshes with an adjusting rack.

[0011] Preferably, one end of the adjusting rack is connected to one end of the electric push rod, and the other end of the electric push rod is connected to the cable management frame.

[0012] Preferably, a support frame is connected to the upper side of the cable management frame, and the outer side of the support frame is inserted into the hole inside the adjusting rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the main step-down medium-voltage switchgear with busbar cable management structure can flexibly adjust the position of the cable management frame according to the limiting requirements before limiting the busbars, which is convenient to use. Moreover, it can limit multiple busbars separately at one time, and the limiting effect is better. It solves the problem of messy wire harnesses inside the switchgear when a large number of components are installed inside and multiple busbars are connected to the outside of each component.

[0014] 1. This main substation switchgear with busbar cable management structure allows for easy cable management. Before using the cable management frame to organize the busbars, the adjusting block is moved to a suitable position along the guide adjustment track. Then, the guide adjustment track and the adjusting block are connected by connecting bolts through threaded grooves to limit the height of the cable management frame. Finally, the positioning block is pressed to adjust the horizontal distance between the cable management frame and the protective door, and to limit the horizontal position of the cable management frame. This main substation switchgear with busbar cable management structure allows for flexible adjustment of the position of the cable management frame according to the limiting requirements before limiting the busbars, making it convenient to use.

[0015] 2. When limiting the busbar position, the main substation switchgear with busbar cable management structure first connects the busbar to the cable management block to initially limit the position of the busbar. Then, the electric push rod connected to the top of the cable management frame is activated, which moves the adjusting rack connected to it and meshes with the adjusting gear on one side. This causes the adjusting gear to rotate, which in turn causes the cable management block connected to the adjusting gear to rotate, thus limiting and clamping the busbar. This main substation switchgear with busbar cable management structure can limit the position of multiple busbars at a time, resulting in a better limiting effect. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a main step-down switchgear with a busbar cable management structure, including a cabinet body 1, a guide adjustment rail 2 and a cable management frame 3. The cabinet body 1 has a heat dissipation groove 101 inside, and a protective door 102 is connected to one side of the cabinet body 1. A handle 103 is connected to one side of the protective door 102.

[0023] The cabinet 1 is equipped with a guide adjustment rail 2, and an adjustment block 203 is inserted into the guide adjustment rail 2. Both the guide adjustment rail 2 and the adjustment block 203 have threaded grooves 201 inside. Both the adjustment block 203 and the guide adjustment rail 2 are provided with connecting bolts 202. The adjustment block 203 is connected to one end of a connecting arm 204 through a pin. The other end of the connecting arm 204 has symmetrical mounting grooves 208 inside. Both mounting grooves 208 are connected to connecting springs 207. Positioning blocks 206 are connected to the opposite sides of the connecting arm 204. A cable management frame 3 is provided on the outside of the connecting arm 204. A positioning hole 205 is provided inside the cable management frame 3. The outer side of the positioning block 206 is inserted into the positioning hole 205 on the adjacent side. A connecting groove 301 is provided inside the cable management frame 3. The side of the connecting arm 204 away from the guide adjustment rail 2 is rotatably connected to the connecting groove 301 through the positioning block 206. The threaded grooves 201 are equidistantly opened inside the guide adjustment rail 2. The positioning holes 205 are symmetrically opened inside the cable management frame 3.

[0024] In practice, to facilitate cable management, before using the cable management frame 3 to organize the busbars, the adjusting block 203 is moved to a suitable position along the guide adjustment track 2. Then, the guide adjustment track 2 and the adjusting block 203 are connected by the connecting bolt 202 through the threaded groove 201 to limit the height of the cable management frame 3. Then, the positioning block 206 is pressed to disengage from the positioning hole 205, and the horizontal distance between the cable management frame 3 and the protective door 102 is adjusted. After the horizontal adjustment of the cable management frame 3 is completed, the positioning block 206 at the mounting groove 208 is pressed again to insert one end of the connecting arm 204 into the connecting groove 301 inside the cable management frame 3. At this time, the positioning block 206 will pop out under the action of the connecting spring 207 and insert into the corresponding positioning hole 205 to limit the horizontal position of the cable management frame 3. This main substation with busbar cable management structure allows for flexible adjustment of the position of the cable management frame 3 according to the limiting requirements before limiting the busbars, making it convenient to use.

[0025] See Figure 3 and Figure 4 It can be seen that the inside of the cable management frame 3 is rotatably connected to the cable management block 302 through a slot, and the cable management block 302 is equidistantly arranged inside the cable management frame 3. The top of the cable management block 302 is connected to an adjusting gear 303, and the outer side of the adjusting gear 303 meshes with the adjusting rack 304. One end of the adjusting rack 304 is connected to one end of the electric push rod 305, and the other end of the electric push rod 305 is connected to the cable management frame 3. A support frame 306 is connected to the upper side of the cable management frame 3, and the outer side of the support frame 306 is inserted into the hole inside the adjusting rack 304.

[0026] In practice, when limiting the busbar, the busbar is first connected to the cable management block 302 to initially limit the position of the busbar. Then, the electric push rod 305 connected to the top of the cable management frame 3 is activated. The electric push rod 305 retracts, driving the adjusting rack 304 connected to it to move. Under the guidance of the internal support frame 306, the adjusting rack 304 meshes with the adjusting gear 303 on one side, driving the adjusting gear 303 to rotate, which in turn drives the cable management block 302 connected to the adjusting gear 303 to rotate, thus limiting and clamping the busbar. This main substation with busbar cable management structure can limit and separate multiple busbars at a time, resulting in a better limiting effect.

[0027] In summary, when using this main substation switchgear with busbar cable management structure, first move the adjusting block 203 along the guide adjusting track 2 to a suitable position, then use the connecting bolt 202 to limit it, press the positioning block 206 to adjust the horizontal distance between the cable management frame 3 and the protective door 102, and limit the horizontal position of the cable management frame 3. Finally, connect the busbar to the cable management block 302, start the electric push rod 305, and through the meshing of the adjusting rack 304 and the adjusting gear 303, drive the cable management block 302 to limit and clamp the busbar.
