3. Binciken Misali Na Amfani Da Kablun Optical-Electrical Mai Sauƙi

Wannan littafi ya zama bayanan bayanai 110 kV da 220 kV sides of a certain intelligent substation. By comparing the specific situations of the application of prefabricated optical-electrical hybrid cables, it specifically elaborates on the main characteristics of the application of prefabricated optical-electrical hybrid cables as follows:

(1) Statistical Analysis of the Specifications and Quantities of Optical-Electrical Hybrid Cables on the 110 kV Side

Based on the double-busbar wiring mode on the 110 kV side and the use of GIS equipment for research, there is a single-set configuration in the integrated device of the intelligent terminal merging unit for the 110 kV power line and the sectionalization; there is a double-set configuration in the integrated device of the intelligent terminal merging unit for the 110 kV main transformer incoming line. Two bus voltage merging units are installed in the intelligent control positions of the busbar equipment.

The following mainly takes the 110 kV line bay as an example. By centrally analyzing the quantities of optical cables and cables between the intelligent control cabinet and the secondary equipment, the specifications and quantities of the optical-electrical hybrid cables on the 110 kV side are sorted out and analyzed.

Table 1 Statistics of cable and optical cable coefficients in 110-kilovolt line intervals

As shown in Table 1, by centrally counting the number of optical fiber cores and cable cores from the process layer to the bay layer in the 110 kV line bay, and comprehensively considering the maximum demand and actual spare cores, a prefabricated optical - electrical hybrid cable composed of one 12 - core optical fiber plus 6×1.5 - sized copper wires is selected for the outgoing line and sectionalization bays. According to the dual - configuration of the main substation, two prefabricated optical - electrical hybrid cables, each composed of 12 - core optical fibers plus 6×1.5 - sized copper wires, are selected for the main intelligent control cabinet on the 110 kV side.

(2) Statistical Analysis of the Specifications and Quantities of Optical - Electrical Hybrid Cables on the 220 kV Side

Based on the double - busbar wiring mode on the 220 kV side and the use of GIS (Geographic Information System) equipment, the intelligent terminals and merging units are uniformly arranged in the intelligent control cabinet. The research on the configuration of the process layer and the bay layer is carried out using a dual - configuration method.

The following mainly takes the 220 kV line bay as a specific example. By statistically analyzing the quantities of optical cables and cables from the intelligent control cabinet to the secondary equipment room, the actual specifications and quantities of the 220 kV optical - electrical hybrid cables are sorted out and summarized.

Considering the dual - configuration on the 220 kV side, the number of cable cores and optical fiber cores of the second cable and its configuration are the same as those of the first cable. The specific content is shown in Table 2. By statistically analyzing the number of cable cores and optical fiber cores from the process layer to the bay layer in the 220 kV line bay, and systematically considering the maximum demand and spare cores, each intelligent control cabinet can use two prefabricated optical - electrical hybrid cables with a specification of 24 - core optical fibers plus 6×1.5 copper wires .

(3) Data Aggregation and Analysis of the Application of Optical - Electrical Hybrid Cables in Intelligent Substations

Based on the data from the above - mentioned statistical process, the analysis shows that in terms of specifications, the prefabricated optical - electrical hybrid cables used inside intelligent substations can be optimized into 24 - core optical cables + 6 - core cables and 12 - core optical cables + 6 - core cables.

The number of cables from the intelligent control cabinets on each side of the 220 kV and main substations to the secondary equipment room can be minimized to two, and the number of cables from the intelligent control cabinet on the 110 kV side to the secondary equipment room can be minimized to one.

As the cost of equipment materials in the investment process continues to decrease, a series of indirect economic benefits are generated, as follows:

• The process - oriented and streamlined levels of cable component assembly are higher, and the work efficiency in the construction process is higher. This can maximize the savings in labor and engineering time and reduce the cost of on - site installation and construction.

• After using prefabricated cables, it can specifically improve the standardization level of users, reduce the variety and quantity of materials, reasonably release the occupancy of the original inventory of users, and reduce the cost of management.

• It reduces the workload in the later operation and maintenance process, has better green and environmental protection performance, and is more in line with the overall requirements of the construction of "two - type and one - standardization" substations.

4. Conclusion

In summary, the application of prefabricated cables in intelligent substations aims to achieve standardized and regulated connections for optical cables and cables between primary and secondary equipment, as well as among secondary equipment. This can specifically enhance the construction efficiency and process quality of secondary equipment during the construction phase.

This article has mainly discussed the application scope and technical characteristics of prefabricated optical - electrical hybrid cables. It has studied and analyzed the specific application of optical - electrical hybrid cables in 220 kV intelligent substations, and summarized and analyzed several common standard interfaces of hybrid cables used in 220 kV substations.

The use of prefabricated optical - electrical hybrid cables can organically integrate cables and optical cables. It can specifically reduce the laying workload at the construction site, decrease the cross - sectional size of cable trenches and the actual occupied area, and effectively cut down the project cost throughout the entire project cycle of intelligent substations.

The research content in this article mainly focuses on how to use optical-electrical hybrid cables to replace prefabricated optical cables for connecting secondary equipment between switchboards across different sites and in areas such as across rooms .
