Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, and in particular relates to a combined high-voltage switch cabinet. Background Art

[0002] High-voltage switchgear refers to electrical products with voltage levels ranging from 3.6kV to 550kV, used for switching, controlling, or protecting power generation, transmission, distribution, conversion, and consumption in power systems. High-voltage switchgear is a crucial piece of equipment in power systems, primarily used to control and protect high-voltage circuits.

[0003] In the case where the power system requires a large number of electrical components, multiple high-voltage switchgear are usually required to be used in conjunction, and the electrical components between adjacent high-voltage switchgear are connected according to the actual situation. However, when the position of the high-voltage switchgear in the power system needs to be changed without replacing the electrical components in the high-voltage switchgear and the line connections between the high-voltage switchgear, since there are generally just multiple high-voltage switchgears side by side, there is no connection and fixation between the high-voltage switchgears, and only a single high-voltage switchgear can be moved independently. It is necessary to disassemble the line connection between the high-voltage switchgears, which is inconvenient and requires reconnecting the lines later, which is troublesome. In addition, the existing high-voltage switchgear is generally not equipped with moving wheels, which is inconvenient to move. Utility Model Content

[0004] In order to solve the technical problem that when multiple high-voltage switch cabinets are used together, they are not connected and fixed, which causes inconvenience when moving, the utility model provides a combined high-voltage switch cabinet.

[0005] The utility model is implemented as follows: a combined high-voltage switchgear cabinet comprises a high-voltage switchgear cabinet body, wherein two connecting mechanisms are provided on the top of the high-voltage switchgear cabinet body, for connecting the two high-voltage switchgear cabinet bodies together to form a whole during the use of the high-voltage switchgear cabinet body, and the two connecting mechanisms are symmetrically arranged, and the connecting mechanism comprises: a fixed block fixedly mounted on the top of the high-voltage switchgear cabinet body, and a first sliding hole is horizontally opened on the fixed block; an insertion rod slidably mounted in the first sliding hole of the fixed block, both ends of the insertion rod extend outside the sliding hole, and the insertion rod is adapted to the first sliding hole; a fixed seat fixedly mounted on the top of the high-voltage switchgear cabinet body, a slot is opened on one side of the fixed seat, and the slot is adapted to the insertion rod; wherein a limiting mechanism is also installed on the high-voltage switchgear cabinet body, and the limiting mechanism is used to cooperate with the two connecting mechanisms so that the two high-voltage switchgear cabinet bodies can be fixed together when combined.

[0006] Preferably, the same push rod is fixedly installed on the same end of the two insertion rods, which is used to push the two insertion rods at the same time so that they are inserted into the slots of the two fixed seats on the other high-voltage switch cabinet body when the two high-voltage switch cabinet bodies are combined. The sliding sleeves of the two insertion rods are provided with springs, which are used to prevent them from exceeding the width space range of the high-voltage switch cabinet body in the natural state when the high-voltage switch cabinet body is not combined.

[0007] and a lockhole that is formed on a pair of locking plates at the side of being raised by the lockhole, and a lockhole that is formed on the side of the holder card, so that the lockhole engages with the holder card in a predetermined manner and the lockhole engages with the first lockhole in a predetermined manner.

[0008] Preferably, a stopper for blocking the push rod is fixedly mounted on the top of the high-voltage switch cabinet body, so that the insertion rod will not fall off the fixed block.

[0009] Preferably, a plurality of wire threading holes are provided on both sides of the high-voltage switch cabinet body, which are used to connect the components in the two high-voltage switch cabinet bodies through wires after the two high-voltage switch cabinet bodies are combined. A dust cover is plugged in the wire threading hole, and the dust cover is provided with a M-shaped slit, which is used to not affect the passage of the connecting wire during threading and to prevent dust when not threading.

[0010] Preferably, universal wheels are installed at the four corners of the bottom of the high-voltage switch cabinet body for moving the high-voltage switch cabinet body.

[0011] Preferably, the four corners of the bottom of the high-voltage switch cabinet body are equipped with support mechanisms for stably supporting the high-voltage switch cabinet body on the ground, and the support mechanism includes: an inner sleeve fixedly installed at the bottom of the high-voltage switch cabinet body, and the universal wheel is located in the inner sleeve; an outer sleeve threadedly sleeved on the outer wall of the inner sleeve, and the outer sleeve and the inner sleeve are both made of stainless steel; a rubber gasket fixedly installed at the bottom of the outer sleeve, which is used to prevent the outer sleeve from slipping when it is supported on the ground.

[0012] Compared with the related art, the combined high-voltage switchgear provided by the present invention has the following beneficial effects:

[0013] The high-voltage switchgear body is equipped with a support mechanism and universal wheels, which not only significantly enhances its stability when stationary but also makes it easy to move.

[0014] In addition, the design of the wire holes facilitates the connection of components between high-voltage switchgears. Wire connection enables functional expansion and flexible configuration. The dust cover with a crisscross slit is easy to operate when wires need to be threaded, and effectively prevents the ingress of dust and debris when wires are not being threaded, thus ensuring the normal operation and life of the components inside the high-voltage switchgear.

[0015] At the same time, the coordinated use of the connecting mechanism and the limiting mechanism enables the two high-voltage switchgear bodies to be fixedly combined into a whole, which is convenient for overall movement. This design allows the switchgear to be easily moved without removing the connecting wires between the two adjacent switchgears, providing great convenience for users.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The present invention provides a combined high-voltage switchgear. Figure 1-15As shown, the combined high-voltage switchgear cabinet includes a high-voltage switchgear cabinet body 1, and two connecting mechanisms are provided on the top of the high-voltage switchgear cabinet body 1 for connecting the two high-voltage switchgear cabinet bodies 1 together to form a whole during the use of the high-voltage switchgear cabinet body 1. The two connecting mechanisms are symmetrically arranged, and the connecting mechanism includes: a fixed block 2 fixedly mounted on the top of the high-voltage switchgear cabinet body 1, and a first sliding hole is horizontally opened on the fixed block 2; a plug rod 3 slidably mounted in the first sliding hole of the fixed block 2, and both ends of the plug rod 3 extend outside the sliding hole, and the plug rod 3 is adapted to the first sliding hole; a fixing seat 5 fixedly mounted on the top of the high-voltage switchgear cabinet body 1, and a slot is opened on one side of the fixing seat 5, and the slot is adapted to the plug rod 3. When the two high-voltage switchgear cabinet bodies 1 are combined, the two plug rods 3 on one high-voltage switchgear cabinet body 1 can be inserted into the slots of the two fixing seats 5; wherein, a limiting mechanism is also installed on the high-voltage switchgear cabinet body 1, and the limiting mechanism is used to cooperate with the two connecting mechanisms so that the two high-voltage switchgear cabinet bodies 1 can be fixed together when combined.

[0035] In this embodiment, two connecting mechanisms are provided on the top of the high-voltage switchgear body 1 to connect the two high-voltage switchgear bodies 1 together to form a whole. At the same time, the high-voltage switchgear body 1 is also equipped with a limiting mechanism, which cooperates with the connecting mechanism to ensure that the two high-voltage switchgears can be fixed together when combined. In this way, when the position of the high-voltage switchgear needs to be moved or changed, the entire body can be moved more conveniently without moving each high-voltage switchgear separately, thereby greatly improving the convenience of operation.

[0036] Specifically, when two high-voltage switchgear bodies 1 are combined, the sides of the two high-voltage switchgear bodies 1 that are close to each other are aligned tightly, that is, the two plug rods 3 on the left high-voltage switchgear body 1 are aligned with the slots on the two fixing seats 5 on the other high-voltage switchgear body 1, and then the two plug rods 3 are moved to be inserted into the slots on the two fixing seats 5, and the two plug rods 3 are limited by the limiting mechanism, so that the two plug rods 3 of the high-voltage switchgear body 1 are fixed between the two fixing seats 5 on the other high-voltage switchgear body 1, so that the two high-voltage switchgear bodies 1 are combined and fixed to form a whole, which is convenient for moving the combined multiple high-voltage switchgear bodies 1 as a whole when needed, which is more convenient.

[0037] In a further preferred embodiment of the present invention, a same push rod 6 is fixedly installed on the same end of the two said insertion rods 3, which is used to push the two insertion rods 3 at the same time so that they are inserted into the slots of the two fixing seats 5 on the other high-voltage switch cabinet body 1 when the two high-voltage switch cabinet bodies 1 are combined. The two said insertion rods 3 are both provided with a spring 4 on the sliding sleeve, which is used to prevent them from exceeding the width space range of the high-voltage switch cabinet body 1 in the natural state when the high-voltage switch cabinet body 1 is not combined.

[0038] In this embodiment, the same push rod 6 is fixedly installed at the same end of the two plug rods 3. In this way, the two plug rods 3 can be pushed simultaneously by pushing the push rod 6, so that they can be inserted into the slots of the two fixing seats 5 on the other high-voltage switchgear body 1, which is relatively convenient to operate. In addition, springs 4 are slidably sleeved on both plug rods 3. These springs 4 will maintain the position of the plug rods 3 in the first sliding hole of the fixing block 2 in the natural state, that is, when the high-voltage switchgear body 1 is not combined, to prevent the plug rods 3 from extending on their own without external force. This design ensures that when the combination function is not in use, the plug rods 3 will not exceed the width and space range of the high-voltage switchgear body 1, thereby ensuring the independence and stability of the high-voltage switchgear body 1.

[0039] In a further preferred embodiment of the present invention, the limiting mechanism includes: a mounting seat 8 fixedly mounted on the top of the high-voltage switchgear body 1, and a second sliding hole is opened on the mounting seat 8; two pin rods 9 are slidably mounted in the second sliding hole on the mounting seat 8, the two pin rods 9 are adapted to the second sliding hole, and the ends of the two pin rods 9 away from each other extend outside the second sliding hole, and pin holes are opened on both sides of the two fixing seats 5 and the two plug rods 3, and the two pin rods 9 extend into the corresponding pin holes respectively for limiting the plug rod 3, so that the plug rod 3 is fixed between the fixing seat 9, thereby connecting and fixing the two high-voltage switchgear bodies 1; a compression spring 10 sliding in the second sliding hole of the mounting seat 8, the compression spring 10 is used to press the two pin rods 9 to insert them into the pin holes; two pinching rods 11 are respectively fixedly mounted on the top of the two pin rods 9, the two pinching rods 11 both pass through the strip hole opened on the top of the mounting seat 8, and the two pinching rods 11 are used to make the two pins 9 approach each other and disengage from the pin holes.

[0040] In this embodiment, the limiting mechanism is designed and implemented in detail. The limiting mechanism mainly includes a mounting seat 8, two pin rods 9, a compression spring 10 and two pinch rods 11. When the two high-voltage switch cabinet bodies 1 are combined, the insertion rod 3 will be inserted into the slot of the fixing seat 5. At this time, the pin rod 9 will also be inserted into the pin holes on the insertion rod 3 and the fixing seat 5, thereby limiting the insertion rod 3, fixing the insertion rod 3 and the fixing seat 5, and then connecting and fixing the two high-voltage switch cabinet bodies 1; in addition, in order to ensure that the pin rod 9 can be inserted into the pin hole and will not fall off, a compression spring 10 is slidably installed in the second sliding hole of the mounting seat 8. This compression spring 10 will apply pressure to the pin rod 9 so that it always remains inserted into the pin hole; finally, in order to facilitate the operation of the pin rod 9, a pinch rod 11 is fixed on the top of each pin rod 9. Both pinch rods 11 pass through the strip hole opened at the top of the mounting seat 8. When it is necessary to release the limit of the pin rod 9 on the insertion rod 3, it is only necessary to pull the two pinch rods 11 closer to each other so that the two pin rods 9 are closer to each other and break away from the pin hole.

[0041] In a further preferred embodiment of the present invention, a stopper 7 for blocking the push rod 6 is fixedly installed on the top of the high-voltage switch cabinet body 1 to prevent the insertion rod 3 from detaching from the fixing block 2 and preventing the insertion rod 3 from falling.

[0042] In this embodiment, the stopper 7 fixedly mounted on the top of the high-voltage switch cabinet body 1 blocks the push rod 6 to prevent the insertion rod 3 from detaching from the fixed block 2 when subjected to external force or misoperation, thereby preventing the insertion rod 3 from falling.

[0043] In a further preferred embodiment of the present invention, a plurality of wire threading holes are provided on both sides of the high-voltage switch cabinet body 1, which are used to connect the components in the two high-voltage switch cabinet bodies 1 through wires after the two high-voltage switch cabinet bodies 1 are combined. A dust cover 12 is plugged in the wire threading hole, and the dust cover 12 is provided with a M-shaped slit, which is used to not affect the passage of the connecting wire during threading and to prevent dust when not threading.

[0044] In this embodiment, a number of wire threading holes are designed on both sides of the high-voltage switch cabinet body 1. The main function of these wire threading holes is to allow the components inside the two high-voltage switch cabinet bodies 1 to be connected through wires after they are combined. Such a design not only enhances the functionality and flexibility of the high-voltage switch cabinet, but also facilitates its expansion and maintenance in actual applications; in addition, in order to prevent dust and debris from entering the wire threading holes, each wire threading hole is plugged with a dust cover 12. These dust covers 12 adopt a M-shaped slit design, so that when threading is required, the connecting wires can be easily passed through, and when not threading, they can effectively block dust and debris, keeping the inside of the high-voltage switch cabinet clean and dry. The design of the wire threading holes and dust covers 12 not only improves the functionality and flexibility of the combined high-voltage switch cabinet, but also enhances its dustproofness and convenience of maintenance, so that it can maintain excellent performance and service life in various environments.

[0045] In a further preferred embodiment of the present invention, universal wheels 13 are installed at the four corners of the bottom of the high-voltage switch cabinet body 1 to facilitate the movement of the high-voltage switch cabinet body 1.

[0046] In this embodiment, universal wheels 13 are installed at the four corners of the bottom of the high-voltage switchgear body 1. The universal wheel 13 is a wheel that can rotate 360 degrees. It has very good mobility and stability, can be easily moved on various ground surfaces, and greatly improves work efficiency.

[0047] In a further preferred embodiment of the present invention, the four corners of the bottom of the high-voltage switchgear body 1 are equipped with support mechanisms for stably supporting the high-voltage switchgear body 1 on the ground, and the support mechanisms include: an inner sleeve 14 fixedly mounted on the bottom of the high-voltage switchgear body 1, and the universal wheel 13 is located in the inner sleeve 14; an outer sleeve 15 threadedly sleeved on the outer wall of the inner sleeve 14, and the outer sleeve 15 and the inner sleeve 14 are both made of stainless steel; a rubber washer 16 fixedly mounted on the bottom of the outer sleeve 15, which is used to prevent the outer sleeve 15 from slipping when it is supported on the ground.

[0048] In this embodiment, support mechanisms are installed at each of the four corners of the bottom of the high-voltage switchgear body 1. This mechanism not only ensures stable support of the high-voltage switchgear body 1 on the ground but also provides convenient adjustment. Specifically, the support mechanism consists of an inner sleeve 14 and an outer sleeve 15. The inner sleeve 14 is fixedly mounted on the bottom of the high-voltage switchgear body 1, while the universal wheel 13 is located within the inner sleeve 14. This design ensures both the mobility of the high-voltage switchgear body 1 and its stability when stationary. The outer sleeve 15 is threadedly mounted on the outer wall of the inner sleeve 14. This structure allows the outer sleeve 15 to move up and down on the inner sleeve 14, thereby supporting the outer sleeve 15 on the ground and preventing the high-voltage switchgear body 1 from moving freely due to the universal wheel 13. Notably, both the inner sleeve 14 and the outer sleeve 15 are made of stainless steel, which is not only durable and rust-resistant, but also ensures the stability of the support mechanism during long-term use. In addition, a rubber washer 16 is fixedly mounted on the bottom of the outer sleeve 15. The rubber gasket increases the friction between the outer sleeve 15 and the ground, thereby playing an anti-slip role and effectively preventing the high-voltage switch cabinet body 1 from accidentally sliding during use and causing safety accidents.

[0049] In summary, compared with the related art, by installing the support mechanism and the universal wheel 13 on the high-voltage switchgear body 1, not only the stability of the high-voltage switchgear body 1 is ensured when it is stationary, but also convenient mobility is given;

[0050] The design of the threading holes allows the components between the high-voltage switchgear body 1 to be easily connected via wires, thereby achieving functional expansion and flexible configuration. The design of the dust cover 12 with a crisscross slit makes it easy to operate when threading is required, and effectively prevents the entry of dust and debris when not threading, thereby ensuring the normal operation and life of the components inside the high-voltage switchgear.

[0051] The coordinated use of the connecting mechanism and the limiting mechanism enables the two pressure switch cabinet bodies 1 to be fixed when combined, making them a whole, thereby facilitating overall movement, and providing great convenience when the connecting wires between the two adjacent pressure switch cabinet bodies 1 do not need to be removed but the pressure switch cabinet bodies 1 need to be moved.

[0052] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
