Description

Centralized optical fiber distribution cabinet based on prefabricated optical cable plug-in box

technical field

The utility model relates to a centralized optical fiber distribution cabinet based on a front-connection prefabricated optical cable plug-in box, which belongs to the field of electrical technology.

Background technique

The layout scheme of the indoor optical fiber distribution unit in the smart substation is generally: the optical fiber distribution box is scattered in many secondary equipment screen cabinets such as protection cabinets, measurement and control cabinets, and switch cabinets. Space for optical cable fusion construction. The connection between the outdoor equipment and the indoor equipment adopts a long optical cable, which enters the cabinet through the inlet hole at the bottom of the screen cabinet, strips the fiber core and enters the optical fiber distribution box at the lower part of the cabinet, and connects through the flange of the optical fiber distribution box after welding , and then a custom-made length of optical fiber jumper is connected to the optical port on the equipment in the cabinet. The on-site welding workload is very large, and it requires professionals to operate. The quality of welded joints varies, leaving hidden dangers for the long-term operation of substations, and cannot meet the long-term development needs of smart substations.

In recent years, the construction of smart substations has vigorously promoted the distribution construction mode, and centralized optical fiber distribution cabinets have also appeared in prefabricated secondary equipment cabins. The layout method of the centralized optical fiber distribution cabinet is an innovative approach in domestic intelligent pilot substations. First of all, the centralized layout of optical fiber distribution units and centralized wiring are conducive to the consolidation of long outdoor optical cables, fully integrating and optimizing the wiring and connection methods, and saving the number of optical cables. The construction of smart substations vigorously promotes the distribution-type construction model, and the more common forms are as follows:

(1) Centrally assemble the traditional optical fiber distribution box. This form still adopts the traditional fusion splicing method, and needs to be constructed at the front and rear sides of the centralized optical fiber distribution at the same time, and a construction space needs to be reserved in front of the cabinet and behind the cabinet.

Because the distribution substation adopts the prefabricated secondary equipment cabin to replace the traditional secondary equipment room, the prefabricated cabin has strict requirements on the number and size of the screen cabinets due to space constraints, and the screen cabinets are often arranged against the wall, and the door can only be opened from the front side. Wiring on the front side. The arrangement of centralized assembly of traditional optical fiber distribution boxes not only wastes the already narrow space in the equipment cabin, but also fails to meet the requirements of prefabricated interior screen cabinets arranged against the bulkhead, doors in front of the screen cabinets, and wiring in front of the device, and construction must be carried out both front and rear , Time-consuming and labor-intensive; and the traditional optical fiber distribution box is large in size, which makes the remaining space in the cabinet narrow, which is not conducive to the arrangement and routing of optical cables, and is not easy to debug and manage.

(2) Centralized arrangement of high-density side-pull junction boxes

Install the junction box on the column of the cabinet, or just keep the panel of the junction box on the column, and the junction box can be pulled out for optical cable wiring. The indoor pigtail cable is plugged into the adapter from the inside, and the prefabricated optical cable outside the cabinet is plugged into the adapter from the outside to complete the connection.

The side-pull junction box type centralized optical fiber distribution cabinet is used for front wiring construction, but because the side-pull junction box needs to be pulled frequently when wiring, the optical cable and tail cable wiring is easy to loosen and be damaged, and the side-pull junction box is relatively large. It makes the arrangement of optical cables difficult, which is not conducive to the arrangement and routing of optical cables, and is not easy to debug and manage.
