Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a GGD four-in-one combination cabinet. Background Technology

[0002] In the design of small prefabricated substations, multiple cabinet types are typically required, including incoming line cabinets, outgoing line cabinets, capacitor banks, and metering cabinets. When the distribution capacity is small (generally less than 200KVA), the number of internal components in these cabinets is limited, resulting in a relatively empty interior space. The traditional approach is to use four separate cabinet types, which not only occupies a large volume and causes serious space waste, but also leads to excessive busbar and sheet metal usage for small-capacity power distribution systems, increasing production costs and resource consumption. Furthermore, it hinders the compact design of small prefabricated substations. Summary of the Invention

[0003] This utility model provides a GGD four-in-one combination cabinet, the purpose of which is to solve the technical problem that the existing small-sized box-type substations require four types of switch cabinets, namely incoming line cabinet, outgoing line cabinet, capacitor cabinet and metering cabinet, which occupy too much space.

[0004] A GGD four-in-one combination cabinet includes a cabinet body. The cabinet body includes four sets of vertically arranged supports, which divide the cabinet body into a first space, a second space, and a third space in sequence. A first support plate is provided in the upper part of the first space, and a frame circuit breaker is provided on the first support plate. A main busbar is provided in the middle of the second space and the third space. The main busbar is connected to the frame circuit breaker. The height of the main busbar is the same as the bottom of the frame circuit breaker. Multiple high-capacity molded case circuit breakers are provided at the bottom of the main busbar in the second space, and multiple low-capacity molded case circuit breakers are provided at the bottom of the main busbar in the third space.

[0008] Furthermore, the projections of each of the first connecting busbars along the support direction overlap, and there is a gap between the projections of each of the first connecting busbars along the back plate direction.

[0009] Furthermore, the cabinet door corresponding to the first space is equipped with a control display panel for the frame circuit breaker, the cabinet door corresponding to the third space is equipped with a capacitor controller connected to the capacitor bank, and the cabinet door corresponding to the second space is equipped with a metering window connected to the main busbar.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3This utility model provides a GGD four-in-one combination cabinet, including a cabinet body 1. The cabinet body 1 includes four vertically parallel supports 2, which divide the cabinet body 1 into a first space 3, a second space 4, and a third space 5 in sequence. The upper half of the first space 3 is provided with a first support plate 13, and a frame circuit breaker 6 is provided on the first support plate 13. The second space 4 and the third space 5 are provided with a main busbar 7 in the middle, which is connected to the frame circuit breaker 6. The height of the main busbar 7 is the same as the bottom of the frame circuit breaker 6. The upper half of the support 2 in the first space 3 away from the second space 4 is provided with a first support beam 8, which supports multiple incoming busbars 9. Each incoming busbar 9 is connected to the input terminal of the frame circuit breaker 6, and the input terminal of each incoming busbar 9 is connected to the power transmission terminal. Each adjacent bracket 2 has a back plate 10 and a cabinet door 11 connected to its side surface. The input and output terminals of each frame circuit breaker 6 are located near the back plate 10. Each incoming busbar 9 is connected to each input terminal of the frame circuit breaker 6 by a first connecting busbar 12. The connection terminals of each first connecting busbar 12 and the incoming busbar 9 are staggered. The output terminal of each frame circuit breaker 6 is connected to the main busbar 7. The projections of each first connecting busbar 12 in the direction of bracket 2 overlap, and there are gaps between the projections of each first connecting busbar 12 in the direction of back plate 10. The output terminal of each of the frame circuit breakers 6 is located below the input terminal of each of the frame circuit breakers 6. A plurality of second connecting busbars 23 are connected between the output terminal of each of the frame circuit breakers 6 and each of the main busbars 7. Each second connecting busbar 23 extends upward with a clearance portion. The clearance portion is connected to the main busbar 7. There is a gap between the clearance portion and the projection of the first connecting busbar back plate 10 in the direction of the clearance portion. The clearance portion coincides with the projection of the first connecting busbar back plate 10 in the direction of the clearance portion.

[0020] Upward-lifting frame circuit breaker: In traditional incoming line cabinets, the incoming busbar is usually located at the bottom of the cabinet, and the main busbar is located at the top. Therefore, the traditional main busbar must first be folded down to connect with the incoming busbar and then folded up to pass through the top of the cabinet, which results in a large number of busbars. In addition, the traditional incoming line cabinet frame circuit breaker is placed in the center of the switch cabinet. This utility model sets the frame circuit breaker 6 in the upper half of the first space, which can reduce the distance from the upper incoming busbar to the circuit breaker and make the height of the output end of the frame circuit breaker 6 the same as the height of the main busbar 7, which greatly saves the number of busbars.

[0021] The height of main busbar 7 is basically the same as the side outlet height of frame circuit breaker 6, which eliminates the need for reversing the busbar arrangement. Traditional low-voltage outgoing cabinets have all main busbars mounted at the top to leave enough space for molded case circuit breakers and cable installation. However, for small-capacity low-voltage power distribution systems, the components and busbars are much smaller than those in conventional power distribution systems, leaving ample space below. Therefore, placing the busbar in the middle is entirely reasonable and does not affect the installation of cables below.

[0022] The lower half of the third space 5 is provided with a second support plate 14, and a capacitor bank 15 is fixedly connected to the second support plate 14. The capacitor bank 15 is connected to one of the multiple small-capacity molded case circuit breakers 17 in the third space 5. A base plate 18 is provided at the bottom of the cabinet, and each bracket 2 is evenly distributed on the base plate 18. A second support beam 19 is provided at the bottom of each bracket 2. A busbar 20 is horizontally arranged at the bottom of the cabinet 1. The busbar 20 passes through each bracket 2 and is set on each second support beam 19. Traditional capacitor cabinets do not have space at the bottom for outgoing cables, but for small-capacity power distribution systems, the capacitance compensation is very small. Placing it on the tray at the bottom of the cabinet does not affect the installation of outgoing cables at the bottom. The capacitor compensation controller is placed on the far right, eliminating the need to leave a separate space for the capacitor bank 15. This reduces the length of the main busbar 7 extension and saves a lot of busbar usage.

[0023] The second space 4 has multiple large-capacity molded case circuit breakers 16 installed at the bottom of the main busbar, and the third space 5 has multiple small-capacity molded case circuit breakers 17 installed at the bottom of the main busbar 7. The large-capacity circuit breakers are placed on the left side because there is more space below on the left side, which facilitates the installation of cables. Since capacitors are placed below on the right side, placing the small-capacity circuit breakers on the right side is a reasonable choice.

[0024] The cabinet door 11 corresponding to the first space 3 is equipped with a control display panel 21 for the frame circuit breaker 6, and the cabinet door 11 corresponding to the third space 5 is equipped with a capacitor controller 22 connected to the capacitor 15. The cabinet surface 11 corresponding to the second space 4 is equipped with a metering window connected to the main busbar 7.

[0025] The second space 4 has a metering window on the cabinet surface 11 that connects to the main busbar 7. In traditional metering cabinets, because the main busbar is at the top, the metering window can only be placed in the middle of the cabinet, and the metering cabinet occupies a separate space. With the main busbar in the middle, the upper space of the cabinet is very empty, which is just right to place the metering window. This makes perfect use of the space.

[0026] In terms of space efficiency, this utility model uses three unit intervals, which are equivalent to the positions of three traditional GGD cabinets, to complete the functions of five traditional GGD cabinets, namely one incoming cabinet, one metering cabinet, one capacitor cabinet, and two outgoing cabinets.
