[0001] This utility model belongs to the field of high and low voltage switchgear technology, specifically a high and low voltage switchgear based on modular assembly. Background Technology

[0002] High and low voltage switchgear are important equipment used in power systems for power distribution, control and protection circuits. They are divided into high voltage switchgear (usually above 1kV) and low voltage switchgear (below 1kV) according to different voltage levels.

[0003] Currently, existing high and low voltage switchgear generally has a large size, which makes it very inconvenient to transport and install during use. This not only makes the switchgear susceptible to accidental damage during transportation, but also significantly increases the transportation cost. In addition, the switch components inside the switchgear cannot be installed in the required positions as needed, which seriously affects the applicability of high and low voltage switchgear. Therefore, it is necessary to design a high and low voltage switchgear based on modular assembly. Summary of the Invention

[0004] To address the aforementioned issues and solve the problems of existing high and low voltage switchgear being generally large in size, which makes transportation and installation extremely inconvenient, not only increasing the risk of accidental damage during transportation but also significantly increasing transportation costs, and preventing the installation of switch components in the required positions, thus severely affecting the applicability of high and low voltage switchgear, this utility model provides a high and low voltage switchgear based on modular assembly. This effectively achieves modular combination functionality, with each module allowing for relatively independent installation of corresponding switch components. This not only facilitates the transportation and use of the switchgear but also streamlines the classification of switch components within the cabinet. Furthermore, it enables the selection and installation of the appropriate number of switch component support components in the required positions, and the installation and disassembly of these support components are relatively convenient. This high and low voltage switchgear has a simple structure and strong practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high and low voltage switchgear based on modular assembly, including a connecting component and multiple protective components. The protective components are used to support and protect the side support components and the support components. The connecting component is used to connect the multiple protective components. The side support components are used to limit the height of the support components. The support components are used to support the switching elements.

[0006] The aforementioned high and low voltage switchgear based on modular assembly includes a cabinet body. One outer wall of the cabinet body has a cabinet groove, and the other outer wall of the cabinet body has a groove and a first slot. One end of the inner wall of the cabinet groove has a first connecting hole, and the other end of the first connecting hole extends to the inner wall of the first slot. The cabinet groove and the groove are connected by a wire hole.

[0007] The aforementioned high and low voltage switchgear based on modular assembly includes a connecting plate. The outer surface of the connecting plate has a second slot, and the inner sidewall of the second slot has a second connecting hole. The inner sidewall of the second slot is engaged with the inner sidewall of the first slot. The diameter of the second connecting hole is the same as the diameter of the first connecting hole. The first connecting hole and the second connecting hole are detachably connected by an external connector.

[0008] The aforementioned high and low voltage switchgear based on modular assembly includes a first end plate and a second end plate. Both the first end plate and the second end plate are detachably connected to the inner side wall of the cabinet slot. A first slot is provided on the upper surface of the first end plate, and a second slot is provided on the outer wall of the bottom surface of the second end plate. One end of a side rod is inserted into the inner side wall of the first slot, and the other end of the side rod is engaged with the inner side wall of the second slot. A side hole is provided on the outer surface of the side rod.

[0009] The aforementioned high and low voltage switchgear based on modular assembly includes a support plate with a socket on its upper surface. The inner wall of the socket and the outer wall of the side rod are interlocked. The side rod and the support plate are detachably connected by fasteners that penetrate the side holes. The outer surface of the support plate has a support hole for detachable connection with an external connector and the outer wall of the switch element.

[0010] In the aforementioned high and low voltage switchgear based on modular assembly, there are two side support components, and the two side support components are symmetrically distributed on the inner sidewall of the cabinet slot.

[0011] In the aforementioned high and low voltage switchgear based on modular assembly, there are multiple second slots, and the multiple second slots are evenly distributed on the outer surface of the connecting plate.

[0012] In the aforementioned high and low voltage switchgear based on modular assembly, there are multiple side holes, and the multiple side holes are linearly and uniformly distributed on the outer surface of the side rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) First, move the first end plate and fit the outer wall of the first end plate against the inner wall of the cabinet slot. Then, rotate the external connector to detachably connect the first end plate to the inner wall of the cabinet slot, thereby detachably connecting the first end plate to the cabinet body. Next, move the side rod and wedge the lower end of the side rod against the inner wall of the first slot to engage the side rod with the first end plate. Then, move the support plate and wedge the inner wall of the insertion hole against the outer wall of the side rod. Then, rotate the fastener along the side hole to detachably connect the support plate with the side rod. At the same time, by opening the... The multiple side holes allow for the selection of a corresponding number of support plates and their installation in the appropriate positions. Subsequently, the second end plate is moved and the inner wall of the second slot is wedged with the upper end of the side rod. The second end plate is then detachably connected to the cabinet, thereby limiting the position between the side rod and the cabinet. This effectively enables the high and low voltage switchgear to have the function of selecting a corresponding number of switch element support components and installing them in the appropriate positions as needed. The installation and disassembly of the switch element support components are relatively convenient, facilitating the inspection and maintenance of the high and low voltage switchgear. The high and low voltage switchgear has a simple structure and strong applicability.

[0015] (2) Move the cabinet and align the cabinets with each other, then move the connecting plate and wedge the inner wall of the second slot with the inner wall of the first slot. Then, along the first and second connecting holes and with the external connector, the connecting plate and the cabinet can be detachably connected, so that multiple cabinets can be quickly assembled. Then, along the support hole, the required switch element can be detachably connected to the support plate. Then, along the wire hole, the external cable can be inserted into the cabinet slot and detachably connected to the switch element. This effectively realizes the modular combination function of the high and low voltage switch cabinet, and the corresponding switch elements can be installed relatively independently between each module. This not only facilitates the transfer and use of the switch cabinet, but also facilitates the classification of the switch elements inside the switch cabinet and improves the control effect of the switch cabinet.

Next, the second end plate 303 is moved, and the inner wall of the second slot 304 is wedged together with the upper end of the side rod 305. Then, the second end plate 303 is detachably connected to the cabinet 101, thereby limiting the position between the side rod 305 and the cabinet 101, effectively achieving... This high and low voltage switchgear has the function of selecting the appropriate number of switch element support components and installing them in the appropriate positions as needed. The installation and disassembly of the switch element support components are relatively convenient, facilitating the inspection and maintenance of the high and low voltage switchgear. Then, the cabinet 101 is moved and aligned with each other. Next, the connecting plate 201 is moved, and the inner wall of the second slot 202 is wedged with the inner wall of the first slot 106.
