Description

Secondary cable color identification group

technical field

The utility model belongs to the field of power grid operation management, in particular to a secondary cable color identification group in a substation.

Background technique

The secondary cable is an indispensable part of the substation, and is responsible for important functions such as data collection, exchange, and control. Efficient and clear cable identification allows maintenance personnel to quickly grasp the function and connection of the cable, and facilitates the maintenance of the secondary system, thereby ensuring the safety of the power grid. At present, secondary cables in substations are identified by number pipes and cable signs. The number pipe is on the cable core connected to the terminal block. Some identify the secondary circuit where the core is located by the circuit number, and some identify the position where the opposite end of the core is connected by the opposite terminal row number. The cable label is hung at the root of the entire cable coming up from the bottom of the screen cabinet, indicating the position of the start and end screen cabinet of the cable, the cable number and the cable model, so that the corresponding cable can be found in the opposite screen cabinet. Among them, all number tubes and cable signs are in the form of black characters on a white background.

At present, this cable identification method mainly has the following deficiencies: 1. Although the cable labels with black characters on a white background are uniform in form, if you want to find a certain cable, you must carefully look at the start and end positions and cable numbers on each cable label, and search one by one. , the search range cannot be narrowed down according to the function and direction of the cable. 2. When the maintenance personnel check the cable signs, the external light is often not enough, and the lighting in the screen cabinet is not enough to illuminate the cable signs at the bottom of the screen cabinet. Therefore, it is often seen that the maintenance personnel check the cable signs one by one with a flashlight. inconvenient. 3. When the maintenance personnel check the line, they often need to find out the cable where the target core is located, so as to grasp the direction and function of the secondary circuit and whether the secondary cable has a spare core. At present, the clearest way is to print the cable number on the number tube, and determine the cable where the core is located by comparing the number tube and the cable number on the cable label. However, this method has certain disadvantages. In addition to the number and terminal row number, a long string of cable numbers must be added, which is time-consuming and laborious, and it is also inconvenient to search. Therefore, this method is not used much, and if this method is not adopted, in order to clear the secondary circuit, the maintenance personnel can only determine the cable by pulling the wire and pulling the wire core, which is time-consuming and labor-intensive and also has potential safety hazards.
