Description

A cable laying structure of a secondary screen cabinet

technical field

The utility model relates to a cable laying structure of a secondary screen cabinet in a substation and a power plant, and belongs to the technical field of cable laying in a substation and a power plant.

Background technique

There are many secondary screen cabinets arranged in the relay protection chamber or control room in the power plant or substation. All the time, the cables (mostly cables) entering and leaving these secondary screen cabinets are often laid through the bottom of the screen cabinet, and the bottom of the screen cabinet Open holes and communicate with the cable trench or access floor layer.

In recent years, the advancement of technology has led to the development of electric power engineering in the direction of digitalization and intelligence, especially in smart substations. Through the use of advanced digital communication, automatic control, intelligent analysis and other technologies, while realizing intelligence, it also makes the access to and from the secondary screen cabinet There are more and more optical cables (fibers) and network cables. Neither optical cables nor network cables have the plasticity of cables. Therefore, the original laying structure has caused defects such as irregular and unsightly laying of cables in the secondary screen cabinet. .

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the existing technology, and provide a simple structure, easy to use and install, adopt the mode of cable running to the bottom and optical cable to go to the top for laying, so that the laying path of the cable is clear, neat and beautiful. The cable laying structure of the screen cabinet.

The purpose of this utility model is accomplished through the following technical scheme, a cable laying structure of a secondary screen cabinet, which includes a secondary screen cabinet installed in a substation or a power plant, the bottom of the secondary screen cabinet Holes are opened, and the cables are arranged from the bottom of the secondary screen cabinet. The cable core wires are routed to the terminal blocks along the space areas on both sides at the rear of the secondary screen cabinet, and bundled into bundles; they pass out of the secondary screen cabinet Cables are bound and laid with cable trench brackets or movable floor brackets;

There is a hole on the top of the secondary screen cabinet, and the optical cables or pigtails are routed to the optical fiber distribution frame or the optical fiber socket of the equipment along the space areas on both sides at the rear of the secondary screen cabinet, and bound in bundles; The optical cables outside the cabinet are laid on bridges on the top of the cabinet.

The cabinet top bridge is a kind of trough bridge or combined bridge, which is closed on all sides and has one or more side panels that can be disassembled to facilitate laying and installation; the cabinet top bridge is erected on the structural frame of the secondary screen cabinet or suspended at the bottom of the building ceiling.

The bridge on the top of the cabinet is matched with the opening on the top of the secondary screen cabinet and connected with rivets or screws.

The beneficial technical effect of the utility model is:

(1) The optical cable enters and exits the screen cabinet from top to bottom from the top of the screen cabinet, which avoids the difficulty of laying from bottom to top due to the softness of the optical fiber, and facilitates construction;

(2) Roofing of the optical cable reduces the total amount of cables passing through the lower part of the screen cabinet, which is conducive to reducing the cable laying capacity of the cable trench and saving the amount of engineering;

(3) The bridge on the top of the cabinet is conveniently integrated with the secondary screen cabinet, and the combined installation is simple and beautiful; at the same time, compared with the laying method of the bracket, the laying of the bridge is more conducive to protecting the optical cable from external damage;

(4) The cables passing out of the bottom of the cabinet shall be bundled and laid with cable trench brackets or raised floor brackets, so that the cable laying path is clear and arranged neatly.

The utility model has the advantages of simple structure, convenient use and installation, and adopts the mode of laying the cable at the bottom and the top of the optical cable to make the laying path of the cable clear, neat and beautiful, which can save the engineering amount of the cable trench, improve the quality of the optical cable laying process, and reduce the construction cost. cost and other characteristics.
