Background Art

[0002] With the acceleration of social development, people's demand for electricity and the requirements for power supply stability have increased significantly. In power transmission, overhead lines and power cables play a key role. Overhead lines are low-cost and easy to maintain, but they are easily affected by environmental factors and have poor stability. Power cables are increasingly becoming the first choice for urban power supply due to their strong resistance to external environmental factors, low failure rate, low maintenance cost, small land occupation and no impact on urban landscape. In the process of cable laying, due to the production and transportation conditions and topological requirements, the cables need to be connected through intermediate joints. As a key accessory, the intermediate joint of high-voltage cables is crucial to ensure the smoothness, sealing and insulation level of the line. Due to its complex structure, it has high requirements on the skill level and working environment of the construction personnel. Any minor defects may cause insulation breakdown, affecting the reliability of power supply and even the operation of the entire system.

[0003] The assembly of high-voltage cable accessories usually requires multiple operating procedures; among the multiple operating procedures, the pretreatment process of high-voltage cable accessories is the top priority. As the basis for subsequent procedures, the construction quality of pretreatment directly affects each subsequent process link. In the traditional cable accessory assembly pretreatment process, due to the large number of subdivided steps in the pretreatment process and the need for multiple tests to ensure the assembly quality, that is, the construction personnel need to frequently check the standards such as the specific stripping length of the outer sheath, and also need to frequently obtain relevant information of the steps, which greatly affects the operation efficiency; multiple length measurements during construction also prolong the construction time; at the same time, the technical capabilities of the operators are different, making it difficult to ensure uniform and reliable construction quality.

The auxiliary method for high-voltage cable accessories assembly pretreatment process according to claim 8, characterized in that: The high-voltage cable accessories assembly pretreatment process includes: Strip off the outer sheath, strip off the metal sheath, scrape off the semi-conductive layer, first pre-treatment inspection, heat straightening, second pre-treatment inspection, strip off the conductor, grind the main insulation, insulation shielding layer processing and third pre-treatment inspection.

10. The auxiliary method for high-voltage cable accessories assembly pretreatment process according to claim 9, characterized in that: When the next preprocessing operation step prompt information outputted corresponds to the first preprocessing test, the second preprocessing test or the third preprocessing test; Scan the construction site with laser and build a 3D cable model based on the scanned images; Compare the cable 3D model with the standard samples in the database to determine whether it meets the standards; If the standard is met, a prompt message indicating that the test is qualified is output; if the standard is not met, a prompt message indicating that the test is unqualified is output; According to the detection qualified prompt information, the next pre-processing operation step of this pre-processing detection step is prompted; According to the detection failure prompt information, the next preprocessing operation step of the previous preprocessing detection step is prompted or the initial preprocessing operation step is prompted.
