Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear installation technology, and in particular to an installation structure and a low-voltage switchgear. Background Technology

[0002] Quick-connect low-voltage switchgear, also known as plug-in distribution panel, is an electrical device used for power control, distribution and protection in power systems, mainly responsible for power transmission, distribution and power conversion.

[0003] The main components inside a low-voltage switchgear include the main incoming circuit breaker, the feeder circuit breaker, and the busbar. They work together to achieve effective power distribution and control. When inspecting the feeder circuit breaker and the busbar, the maintenance personnel usually need to disassemble the back panel for maintenance. However, if the low-voltage switchgear is installed against the wall, the cabinet cannot be easily moved, which will cause inconvenience to the actual maintenance work.

[0004] To facilitate installation and commissioning, we propose an installation structure and a low-voltage switchgear. Utility Model Content

[0005] In view of the above problems, the installation structure in this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an installation structure, comprising a plate, the plate comprising a first block and a second block, wherein the second block is separable from the first block; the first block and the second block are respectively used to install different component groups.

[0007] In a preferred embodiment of the installation structure described in this utility model, both the first block and the second block are provided with a plurality of connection holes.

[0008] In a preferred embodiment of the installation structure described in this utility model, both the first block and the second block are fixedly installed using screws through the connecting holes.

[0009] As a preferred embodiment of the installation structure described in this utility model, the second block is provided with a plurality of assembly holes.

[0010] One of the beneficial effects of this utility model is that by dividing the board for installing the component group into two parts, namely the first block and the second block, when some components can be disassembled and repaired individually, they can be installed on the second block. Workers can directly remove the second block to maintain the relevant components, thus avoiding the inconvenience caused by having to disassemble and re-enclose the board for maintenance when encountering low-voltage switch cabinets installed against the wall.

[0011] In view of the above problems, the low-voltage switchgear of this utility model is proposed.

[0012] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-voltage switch cabinet, which includes an installation structure, and also includes a component group, including a main incoming circuit breaker, a feeder circuit breaker, and a busbar that is plugged into and plugged into the feeder circuit breaker; and a cabinet body, wherein plates are installed inside the cabinet body.

[0013] In a preferred embodiment of the low-voltage switchgear described in this utility model, the main incoming circuit breaker is installed on the first block; and the feeder circuit breaker and the busbar are each installed on the second block.

[0014] As a preferred embodiment of the low-voltage switchgear described in this utility model, the second block has a corresponding mounting space; and the mounting space, in addition to accommodating the installation of feeder circuit breakers, can also accommodate busbars of different sizes and specifications, such as 36P, 42P, 54P, and 66P.

[0015] In a preferred embodiment of the low-voltage switchgear described in this utility model, the busbar is installed and connected through assembly holes.

[0016] As a preferred embodiment of the low-voltage switchgear described in this utility model, the cabinet body includes an outer door panel and a rear sealing panel, and a base is provided at the bottom of the cabinet body.

[0017] As a preferred embodiment of the low-voltage switchgear described in this utility model, a top cover plate is provided above the cabinet body, and the top cover plate gradually decreases in height from the center to both sides.

[0018] Another beneficial effect of this utility model is that the main incoming circuit breaker is installed on the first block, and the feeder circuit breaker and busbar are installed on the second block. The staff can disassemble the second block separately to maintain the components installed on it. In addition, the second block has corresponding space for installation, so that different specifications of busbars can be installed. The busbar capacity can be quickly expanded without changing the cabinet's external dimensions. Attached Figure Description

[0033] Example 1

[0034] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an installation structure, which includes a plate 100. The plate 100 includes a first block 101a and a second block 101b, and the second block 101b can be separated from the first block 101a. The first block 101a and the second block 101b are respectively used to install different component groups.

[0035] The board 100 is used to arrange the component groups inside the low-voltage switchgear. The board 100 is divided into two areas: a first block 101a and a second block 101b. The first block 101a and the second block 101b are detachable and can be disassembled. The first block 101a and the second block 101b can be of any shape, such as... Figures 1-4 As shown, for ease of maintenance, different component groups are distributed in corresponding blocks. The first block 101a and the second block 101b need to have sufficient space to facilitate the arrangement of the corresponding component groups.

[0036] In summary, when installing components in a low-voltage switchgear, to facilitate subsequent maintenance and prevent environmental requirements that necessitate wall mounting, and to address the increased maintenance difficulties caused by moving the switchgear and disassembling the back panel when maintaining certain components, a first block 101a and a second block 101b are provided. Workers can directly disassemble the second block 101b to repair the relevant components.

[0037] Example 2

[0038] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that a plurality of connecting holes 101a-1 are provided on both the first block 101a and the second block 101b.

[0039] Preferably, both the first block 101a and the second block 101b are fixedly installed using screws through the connecting hole 101a-1.

[0040] Preferably, the second block 101b is provided with a plurality of assembly holes 101b-1.

[0041] The connection holes 101a-1 are preferably symmetrically arranged on both sides of the first block 101a and the second block 101b. The first block 101a and the second block 101b can be connected to the low-voltage switch cabinet by screws. When it is necessary to repair the components on the second block 101b, the screws on top can be removed directly.

[0042] The second block 101b has a reserved mounting hole 101b-1 for installing related components.

[0043] In summary, board 100 is divided into a first block 101a and a second block 101b, which are fixed to the low-voltage switchgear by connecting holes 101a-1 and screws. When some components need to be repaired, the second block 101b can be disassembled separately. The overall design facilitates daily installation and debugging by the staff.

[0044] Example 3

[0045] Reference Figures 1-9 This is the third embodiment of the present invention. This embodiment provides a low-voltage switch cabinet, which includes a component group 200, including a main incoming circuit breaker 201a, a feeder circuit breaker 201b, and a busbar 201c that is plugged into and plugged into the feeder circuit breaker 201b; and a cabinet body 300, on which a plate 100 is installed.

[0046] Preferably, the main incoming circuit breaker 201a is installed on the first block 101a; and the feeder circuit breaker 201b and the busbar 201c are each installed on the second block 101b.

[0047] The low-voltage switchgear includes a quick-connect busbar 201c for the quick-plug feeder circuit breaker 201b, and a universal adapter integrated connector. This allows for hot-plugging of the feeder circuit breaker for maintenance and capacity expansion without interrupting the main incoming circuit breaker 201a. At this time, the feeder circuit breaker must be in the open state, with the incoming terminals energized and the outgoing terminals de-energized, so as not to affect other feeder circuits.

[0048] Preferably, the second block 101b has a corresponding installation space M; and the installation space M can accommodate, in addition to accommodating the feeder circuit breaker 201b, busbars 201c of different sizes such as 36P, 42P, 54P, and 66P.

[0049] The 201c quick-connect busbar can be modularly installed, such as... Figure 5As shown, the second block 101b has corresponding installation space M, which can be used to install 66P, 54P, 42P, and 36P busbars 201c. Through project application, the busbar capacity can be quickly expanded without changing the cabinet's external dimensions.

[0050] Preferably, the busbar 201c is installed and connected through the mounting hole 101b-1.

[0051] Modular assembly holes 101b-1 are arranged in the second block 101b. Several assembly holes 101b-1 are set according to the size requirements, mainly to assist the staff in installing the busbar 201c.

[0052] In summary, this design allows the panel 100 to be installed in two separate sections, enabling the quick-access cabinet to be installed independently or against a wall. This allows staff to replace or maintain related component groups directly by removing the second section 101b from the front of the cabinet when inspecting or expanding the busbar 201c without disassembling the rear cover 302. This is suitable for situations where the cabinet is installed against a wall on-site and the rear cover 302 cannot be removed.

[0053] Example 4

[0054] Reference Figures 1-9 This is the fourth embodiment of the present utility model. This embodiment is based on the previous embodiment, except that the cabinet body 300 includes an outer door panel 301 and a rear sealing panel 302, and a base 303 is provided below the cabinet body 300.

[0055] Preferably, a top cover plate 304 is provided above the cabinet body 300, and the top cover plate 304 has a gradually decreasing trend from the center to both sides.

[0056] In summary, low-voltage switchgear may be installed indoors or outdoors depending on the usage environment. The 304 stainless steel top cover is designed with a certain slope to guide rainwater from both sides during rain, preventing rainwater accumulation and ensuring the long-term operation of the equipment.
