Description

A front wiring cabinet

technical field

The invention relates to a front wiring cabinet.

Background technique

The secondary equipment of a traditional substation mainly includes protection, monitoring, metering, power supply and other auxiliary systems, and is centrally arranged in the secondary equipment room. The equipment is installed in front of the panel and wired behind the panel. In recent years, the State Grid Corporation of China has innovated the construction mode of substation projects, vigorously promoted the core concept of "standardized design, factory processing, and assembled construction", and promoted the use of prefabricated cabin-type secondary combination equipment for smart substations. In the new generation of smart substations, single-chamber double-row has been widely used due to its advantages of high space utilization, low cost, and high degree of prefabrication. The characteristic of this structure type is that a row of panel cabinets is arranged in the cabin close to the side walls of the long sides, and the middle of the two rows of panel cabinets is the inspection and maintenance channel. Since the two rows of secondary equipment must be placed against the bulkhead, only the secondary equipment Open the door at the front side, and change the traditional screen assembly mode of front-panel installation and rear-panel wiring to front-mounting and front-display screen assembly.

At present, the structural layout of the 800mm wide front wiring and front display panel used in the new generation of smart substations is as follows: face the panel, the entire frame structure is set to the right offset, the right side is close to the side panel of the panel, and the left side is the terminal installation area and maintenance In the left part of the area, field cables are arranged near the left panel of the cabinet, and in the right part, redundant jumper fibers or field optical cables are arranged near the left side of the equipment. Covers internal wiring status. On the right side of the frame, from top to bottom, there are open space installation area and equipment installation area. The equipment with front wiring and front display structure is directly installed on the front module hole of the cabinet. The label frame panel, pressure plate panel, and empty panel are four The front convex panel of the first outrigger is installed on the front module hole of the cabinet, and the height of the front convex panel is the same as that of the display device panel in front of the front wiring. The group screen layout has the following problems:

(1) It is inconvenient to disassemble and assemble the equipment: since the equipment to be installed is in the front wiring and front display mode, there is a distance of 130mm between the equipment panel and the equipment ear at the installation place of the module hole of the panel; the component installation panel and the empty panel are front The structural form of the convex plate also has a distance of 130mm from the installation place. The device and the panel are installed close to the right rib of the cabinet, and the space is limited. Even if the extension tool is used to disassemble the equipment, the screws often fall off and the installation holes are not easy to install, which is extremely inconvenient to operate. (2) The aesthetics of the overall layout is not good: the right-biased frame structure does not conform to the traditional "symmetrical beauty" aesthetics; in addition, the equipment that does not have front wiring and front display currently uses the wiring side to the outside and the panel to face inward installed on the front modulus hole of the cabinet, so that it is not on the same plane as the front panel of the equipment with front wiring and front display, which affects the appearance of the overall screen layout; in addition, because the empty panel is a four-legged The front convex panel is installed on the front module hole of the cabinet, and the four legs need to occupy at least 2U of height space. If there is a 1U height space between the devices, it cannot be sealed with an empty panel, and the 1U space is not blocked. , which greatly affects the overall aesthetics of the cabinet; (3), the layout of departmental components is limited: due to the current frame's right-offset layout, the opening angle of the pressure plate panel is limited, and only 6 pressure plates can be arranged in each row. The row can hold 9 pressure plates.
