Problems solved by technology

[0003] a. The secondary equipment in the cabin is arranged in a single row, such as figure 2 As shown, a single row of secondary equipment devices is arranged inside the cabin, leaving space for operation and wiring at the front and rear; however, only a single row of secondary equipment devices is arranged in the cabin, which reduces the capacity of a single secondary equipment cabin by half, and needs to be increased during project implementation. The number of cabins to meet the function, thus increasing the cost
[0004] b. Use the secondary equipment device of the cradle, such as image 3 As shown, the secondary equipment device in the cabin does not have a rear door, and its back is closed, and a frame 3-2 that can be rotated out is installed inside, and the secondary equipment device 3-1 and its wiring and routing are all installed on the frame 3-2. 2. During equipment installation and wiring, put down the front door 3-3 of the cabin and shake out the frame 3-2; however, this method needs to increase the width of the cabin to ensure that the equipment in the cabin can meet the rotation requirements, and it is easy to be damaged during the rotation process Cables and optical cables, and it is easy to cause potential hidden dangers such as loosening and falling off of the wiring. At the same time, it is not easy to unscrew the cradle for testing and debugging when the power is on. Since the wiring of the secondary equipment of the cradle is located inside the box, the space is narrow, which is not conducive to operate
[0005] c. Doors are opened on both sides of the cabin, and the back of the secondary equipment cabinet in the cabin is open. There is no rear door. The traditional installation in front of the panel and wiring behind the panel is adopted. Doors are set on both sides of the cabin at the corresponding positions of the secondary equipment cabinets. Project implementation Opening the external cabin door can complete the wiring and testing work, but it is difficult to carry out the debugging work because the human-computer interaction and wiring belong to the inside and outside of the cabin; in this way, firstly, opening the doors on both sides of the cabin increases the manufacturing cost and affects the pre-installed type. The overall appearance of the secondary equipment is not conducive to the spraying or pasting of logos and product names outside the cabin; secondly, the opening of the cabin door destroys the integrity of the bulkhead seal, resulting in a decline in the cabin’s protection level, fire rating, and impact resistance. In addition, in actual engineering applications, regardless of wiring or debugging, the staff need to detour inside and outside the cabin, which seriously affects work efficiency; Installing rainproof (canopy) facilities on the outside of the cabin increases the corresponding manufacturing cost and wastes the site space

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as Figure 4 As shown, the traditional secondary equipment adopts the method of front-panel installation and rear-panel wiring. The human-computer interaction module 1 is located on the front side of the device, and there is a motherboard 3 inside the box body 4. The connectors are connected to each other. The plug-in 2 is provided with a wiring interface and a test port. The end face of the plug-in faces the opposite direction to the human-computer interaction module. When wiring or testing, pull out the plug-in 2 from the end face, such as Figure 4 The direction indicated by the arrow in the middle; if it is necessary to monitor the status of the system or press keys, etc., the user needs to operate on the human-computer interaction module 1 in front.

[0032] Such as Figure 5 As shown, the secondary equipment device for fro...

Abstract

The invention discloses a secondary apparatus for installation, wiring and operation in front of a board. A traditional plug-in connector inserted backwards is inserted in from the installation direction of a man-machine interaction module which is simultaneously erected on the front side of the plug-in connector for installation. The plug-in connector and a terminal on the rear side of the secondary apparatus are exposed by overturning or translating the man-machine interaction module, so that operations of wiring, testing, debugging and the like can be finished, and the functions of installation, wiring and operation in front of the board can be achieved. The secondary apparatuses can be arranged in a secondary apparatus compartment as many as possible, and the aims of utilizing the space in the compartment to the maximum, reducing the manufacturing cost, avoiding protection risks and the like can be achieved.

Description

technical field [0001] The invention relates to a secondary equipment device capable of front-panel installation, front-panel wiring, and front-panel operation, which is convenient for installation, wiring and debugging on a secondary equipment screen cabinet where a back door cannot be opened, and belongs to the technical field of secondary equipment of electric power systems. Background technique [0002] According to the core concept of "standardized design, factory production, and prefabricated construction" put forward by the State Grid Corporation of China, the use of outdoor prefabricated secondary equipment cabins is being vigorously promoted, which can reduce the actual area of ​​the project, facilitate on-site installation, and simplify On-site wiring, easy on-site inspection and maintenance. The prefabricated secondary equipment compartment is produced, installed, and transported by the factory as a whole, and realizes factory integration and factory commis...
