Description

A prefabricated cabin type combined secondary equipment wiring structure

technical field

The utility model relates to a wiring structure of prefabricated cabin type combined secondary equipment, which belongs to the technical field of prefabricated cabin type combined secondary equipment.

Background technique

With the promotion of the construction of standard distribution substations, the application of prefabricated cabin-type secondary combination equipment has played an important role in realizing modular construction in substations. Prefabricated cabin-type secondary combination equipment, hereinafter referred to as prefabricated cabin, is composed of prefabricated cabin, secondary equipment screen cabinet or rack, cabin auxiliary facilities, etc., and the production, assembly, wiring, debugging and other work are completed in the factory. It is transported to the project site as a whole in the form of a box room, and installed in place and on the foundation. However, after the prefabricated cabin arrives at the project site, it is still necessary to carry out more wiring work on site to connect with external equipment. On site, it is necessary to connect the external cables to the interior of the prefabricated cabin through the reserved wire hole at the bottom of the prefabricated cabin. During this process, it is necessary to disassemble and assemble the anti-static floor on the ceramic surface in the prefabricated cabin and the baffle plate of the inlet hole in the bilge, which will often damage the anti-static floor on the ceramic surface and may cause difficulties to the cables that have been connected in the prefabricated cabin. expected adverse effects. It not only prolongs the on-site wiring time, but also increases the failure rate of on-site wiring, failing to realize the real "fabricated construction".

There are two types of existing wiring technologies. One is to manufacture and produce cables in the factory that can only pre-connect some of the screen cabinets. All cables or optical fibers that need to be connected to external equipment need to be wired at the engineering site. This method cannot reflect the advantages of the secondary combination equipment of the prefabricated cabin at all, and does not conform to the modular concept of "prefabrication" and "combination". Leaving most of the wiring work to the engineering site increases the time and labor cost of on-site wiring; and every cable introduced from outside the cabin during on-site construction must be connected to the corresponding equipment or interface, and the number of cables is huge It is large and has many interfaces, which is not conducive to wiring and arrangement, and it is easy to cause confusion of cables; when wiring, the on-site construction personnel also need to remove the ceramic surface anti-static floor in the prefabricated cabin, and restore it after the wiring is completed, which is easy to damage the anti-static The ceramic veneer of the floor, and the flatness of the floor plane in the cabin after restoration will also be greatly affected.

The other one has a centralized wiring cabinet in the prefabricated cabin, which is an improvement on the first scheme. However, at the project site, the external cables enter the cable through the bilge hole and are connected to the centralized distribution cabinet. They still need to enter the prefabricated cabin and remove part of the anti-static floor for wiring. In addition, because the external incoming lines of the prefabricated cabin and the wiring between the screen cabinets in the cabin must be connected to the centralized distribution cabinet, the cables at the centralized distribution cabinet are very dense, which increases the difficulty of wiring and the separation of internal and external cables, optical fibers and cables. .

In this design, a special electrical interface cabinet is installed in the preset cabin. The cabinet body is placed against the bulkhead, and an operation door is opened on the bulkhead. When the door is opened, the aviation plugs in the electrical interface cabinet can be connected directly without entering Wiring can be completed in the cabin and by dismantling the floor, which makes up for the deficiencies in the prior art.

Utility model content

Purpose: In order to overcome the deficiencies in the prior art, the utility model provides a prefabricated cabin type combined secondary equipment wiring structure.

Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the utility model is:

A prefabricated cabin-type combined secondary equipment wiring structure, including: a prefabricated cabin, an electrical interface cabinet, a wire inlet, and an operating door. and the back are provided with mounting plates, the front mounting plate is provided with optical cable sockets, and the rear mounting plate is provided with cable sockets; the rear bulkhead of the electrical interface cabinet is provided with an operation door; the bottom of the electrical interface cabinet is provided with an incoming line mouth.

It also includes prefabricated optical cables and prefabricated cables. There is a wiring trough box under the floor of the prefabricated cabin. The wiring trough box is divided into upper and lower layers.

It also includes aviation plugs, and the ends of the prefabricated optical cables and the prefabricated cables are all provided with aviation plugs.

As a preferred solution, the back of the electrical interface cabinet faces the operation door.

Beneficial effects: the utility model provides a prefabricated cabin-type combined secondary equipment wiring structure, which aims to improve the deficiencies in the two existing schemes. The wiring between the inner screen cabinets is completed in the factory, and the cable sockets are prefabricated, so that "plug and play" can be realized after the prefabricated cabin arrives at the engineering site; secondly, the utility model can enable workers to complete the external wiring without entering the prefabricated cabin. Cable access eliminates the need to disassemble and assemble the ceramic anti-static floor in the prefabricated cabin, saving man-hours, improving efficiency, and completely avoiding the risk of damaging the floor and destroying the completed lines in the cabin.
